AB  - In this study, a total of 30 poultry (chicken and laying hens) feed samples collected from different poultry farms in Serbia in 2016 were tested for fungal and aflatoxin contamination. Using the plate count and standard mycological methods, total fungal counts and potentially toxigenic fungal genera were determined. Natural occurrence of aflatoxin B1 (AFB1) was detected by ELISA (enzyme-linked immune sorbent assay) method. The total fungal count was in the range from 1 x 102 (2 log CFU g-1 ) to 1.83 x 105 CFU g-1 (5.26 logCFU g-1 ). The majority of the chicken feeds (78.57%) had the total fungal count in the ranged from 1 x 102 to 4.8 x 104 CFU g-1 , whereas in 68.75% of the laying hens feeds it was ranged from 5.3 x 104 to 1.83 x 105 CFU g -1 . In 21.43% of the chicken feeds fungal contamination reached the level above the regulation limits. Three potentially toxigenic fungal genera, Aspergillus, Fusarium, and Penicillium, have been identified. In the tested poultry feed samples, more samples contaminated with Aspergillus were determined compared to samples contaminated by Fusarium and Penicillium species. The AFB1 was detected in concentrations from 1.34 to 18.29 g kg-1 , with an average of 4.47 and 4.56 g kg-1 in the chicken and laying hens feed samples, respectively. In 14.29% of the chicken feeds, the level of AFB1 was above the regulation limits. The obtained results confirmed the importance of continuous mycological and mycotoxicological control of poultry feed, as well as need to improve risk assessments of such contaminants along the food chain.
AB  - U ovom radu je 30 uzoraka hrane za živinu sakupljenih tokom 2016. godine iz različitih živinarskih farmi u Srbiji, ispitivano na prisustvo gljiva i aflatoksina u uzorku. Primenom metode razrešenja i standardnih mikoloških metoda utvrđeni su ukupan broj gljiva i identifikovani su potencijalno toksigeni rodovi gljiva. Prirodna pojava aflatoksina B1 (AFB1) utvrđena je primenom biohemijske imunoadsorpcione metode (ELISA). Ukupan broj gljiva bio je od 1 x 102 (2 logCFU g-1 ) do 1,83 x 105 CFU g-1 (5.26 log CFU g-1 ). Najveći broj uzoraka hrane za piliće (78,57%) imao je ukupan broj gljiva u rangu od 1 x 102 do 4,8 x 104 CFU g-1 , dok je 68,75% uzoraka hrane za nosilje imalo ukupan broj gljiva u rangu od 5,3 x 104 do 1,83 x 105 CFU g-1 . U 21,43% hrane za piliće ustanovljen je nedozvoljen ukupan broj gljiva. Identifikovana su tri potencijalno toksigena roda gljiva Aspergillus, Fusarium i Penicillium. Najveći broj ispitivanih uzoraka hrane za živinu bio je kontaminiran Aspergillus vrstama, u odnosu na Fusarium i Penicillium vrste koje su kontaminirale manji broj uzoraka. Rang sadržaja AFB1 bio je od 1,34 do 18,29 µg kg-1 , sa prosečnim sadržajem od 4,47 µg kg-1 u uzorcima hrane za piliće, i 4,56 µg kg-1 u uzorcima hrane za nosilje. U 14,29% uzoraka hrane za piliće ustanovljen je nedozvoljen sadržaj AFB1. Dobijeni rezultati potvrđuju značaj stalne mikološke i mikotoksikološke kontrole hrane za živinu, kao i potrebu za usavršavanjem procene rizika od štetnih (gljivičnih) kontaminenata u lancu ishrane.

AB  - This review paper aims to give an overview of the literature data on common behavioral and health problems in broiler chickens and laying hens and to explain their interrelation and relation to the rearing system. In the initial part, the mechanism of arising of the most common forms of abnormal behavior and the way they affect the poultry are briefly described. Furthermore, the possibility of poultry to fulfill behavioral needs in different rearing systems and some of the consequences to the birds in the case of their inability to meet their needs are displayed. The influence of the main microclimate and space factors is also discussed, as well as the occurrence of some infectious, parasitic and production diseases in poultry rearing systems. The welfare problems of poultry are complexes and most often caused by the system design and its improper use. Continuous work on improving rearing systems is as important as better informing the producers and the public on poultry welfare problems.

AB  - This study presents research results of quality and incubation values for Isa Brown hybrid eggs. Eggs were produced in the 33rd week of age at the production peak. Research was conducted on the sample of 252 incubation eggs (240 fertilized eggs). Chick hatchability compared to the number of inserted eggs was 86.51%, and compared to the number of fertilized eggs 90.83%. Average values for quality parameters of brooding eggs and incubation results were as follows: egg weight before insertion 58.41 g, egg length 5.49 cm, egg width 4.29 cm, egg shape index 78.16% and egg volume 53.14 cm3, one day old chick weight was 39.15 g, absolute egg weight loss was 6.60 g, relative egg weight loss was 11.31% and relative chick share in the egg weight was 67,03%. Statistically justified (P<0.001; P<0.01; P<0.05) correlation (complete one) was determined between egg weight and egg width (0.908), egg weight and egg volume (0.923) and egg weight and chick weight (0.918), very strong correlation was determined between egg weight and egg length (0.870), strong correlation was determined between egg weight and absolute egg weight loss (0.690), weak correlation was determined between egg shape index and egg width (0.395), and very weak correlation was determined between egg weight and egg shape index (0.188), egg weight and relative egg weight loss (-0.166), egg shape index and egg length (-0.147) and egg shape index and chick weight (0.189). Between egg weight and relative chick share in the egg weight, egg shape index and absolute egg weight loss, egg shape index and relative chick share in the egg weight no statistically justified (P>0.05) correlation was determined.

AB  - This study was carried out in order to investigate the natural occurrence of toxigenic fungi and levels of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in the maize stored immediately after harvesting in 2016 and used for animal feed in Serbia. A total of 22 maize samples were collected from four different districts across the country: City of Belgrade (nine samples), Šumadija (eight samples), Podunavlje (four samples) and Kolubara (one sample). Toxigenic fungi were identified according to the morphological characteristics whereas the mycotoxins contamination were detected using biochemistry enzyme-linked immuno-sorbent (ELISA) assay. The tested samples were mostly infected with Aspergillus, Fusarium and Penicillium spp., except that one sample originated from Kolubara was not contaminated with Aspergillus species. Fusarium graminearum was the most common species in the maize sample from Kolubara district (60%), F. verticillioides in the maize samples from Podunavlje (43.75%) and City of Belgrade (22.4%) districts, and Penicillium spp. in the maize samples from Šumadija district (26.38%). In the analysed maize samples the presence of Aspergillus species was low (0-1.78%). Mycotoxicological analysis revealed the presence of zearalenone (ZEA), deoxynivalenol (DON) and aflatoxin B1 (AFB1) in all the investigated samples, except that DON and AFB1 were not recorded in the samples from Podunavlje and Kolubara districts, respectively. The investigated samples were highly contaminated with ZEA, with incidence of 100% for the samples from Šumadija, Podunavlje and Kolubara districts and 88.89% for the samples from City of Belgrade district. In addition, the samples contamination with DON was 100% and 22.2% for the samples from Šumadija, Kolubara and City of Belgrade, districts, respectively. The highest number of AFB1 positive samples was found in Šumadija district (87.5%), while in the City of Belgrade and Podunavlje districts, 55.56% and 50% AFB1 positive samples were established, respectively. Generally, remarkable infection of all the tested samples with toxigenic fungal species from Aspergillus, Fusarium and Penicillium genera were recorded. In addition, high contamination with mycotoxins ZEA, DON and AFB1 were also recorded; nevertheless, only in one sample the level of DON exceeded the allowed legal limit (1750 μg kg-1 ) according to Regulation for unprocessed maize. Therefore, permanent mycological and mycotoxicological analyses of maize grain are necessary for risk assessment of fungal and mycotoxin contamination throughout the food chain.
AB  - Ispitivanja u ovom radu izvedena su s ciljem da se odredi prirodna pojava potencijalno toksigenih gljiva iz rodova Aspergillus, Fusarium i Penicillium i sadržaj mikotoksina zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u kukuruzu uskladištenom neposredno posle berbe u 2016. godini i korišćenom za ishranu životinja. Ukupno 22 uzoraka zrna kukuruza sakupljeni su iz četiri regiona u Srbiji: Beogradski (devet uzoraka), Šumadijski (osam uzoraka), Podunavski (četiri uzorka) i Kolubarski (jedan uzorak). Toksigene vrste gljiva su identifikovane na osnovu morfoloških osobina, a sadržaj mikotoksina određen je pomoću biohemijske, imunoadsorpcione enzimske metode (ELISA). Ispitivani uzorci kukuruza većinom su bili inficirani sa Aspergillus, Fusarium i Penicillium spp., izuzev što u uzorku iz Kolubarskog regiona nisu bile identifikovane Aspergillus vrste. Fusarium graminearum bila je najučestalija vrsta u uzorku kukuruza iz Kolubarskog regiona (60%), F. verticillioides u uzorcima iz Podunavskog (43,75%) i Beogradskog regiona (22,4%) i Penicillium spp. u uzorcima iz Šumadijskog regiona (26,38%). U ispitivanim uzorcima kukuruza zastupljenost Aspergillus vrsta bila je niska (0-1,78%). Mikotoksikološkim analizama ustanovljeno je prisustvo zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u svim ispitivanim uzorcima kukuruza, izuzev što DON nije detektovan u uzorcima iz Podunavskog a AFB1 u uzorku iz Kolubarskog regiona. Ispitivani uzorci su visoko kontaminirani sa ZEA, 100% uzoraka iz Šumadijskog, Podunavskog i Kolubarskog regiona i 88,89% uzoraka iz Beogradskog regiona. Isto tako, sa DON bilo je kontaminirano 100% uzoraka iz Šumadijskog i Kolubarskog regiona i 22,2% iz Beogradskog regiona. Najveći broj AFB1 pozitivnih uzoraka ustanovljen je u Šumadijskom regionu (87,5%), dok je u Beogradskom i Podunavskom regionu ustanovljeno 55,56% i 50% AFB1 pozitivnih uzoraka, respektivno. Uopšteno razmatrajući, u ovim analizama ustanovljena je visoka zastupljenost toksigenih vrsta u svim ispitivanim uzorcima kukuruza. Isto tako, ustanovljena je visoka kontaminiranost uzoraka sa mikotoksinima ZEA, DON i AFB1, iako je samo u jednom uzorku sadržaj DON premašio dozvoljeni limit (1750 μg kg-1 ) prema zakonskoj regulativi za neprerađeni kukuruz. Zbog toga, stalne mikološke i mikotoksikološke analize zrna kukuruza neophodne su radi ocene rizika od gljivične i mikotoksin kontaminacije u lancu ishrane.

Ispitivani uzorci kukuruza većinom su bili inficirani sa Aspergillus, Fusarium i Penicillium spp., izuzev što u uzorku iz Kolubarskog regiona nisu bile identifikovane Aspergillus vrste. Fusarium graminearum bila je najučestalija vrsta u uzorku kukuruza iz Kolubarskog regiona (60%), F. verticillioides u uzorcima iz Podunavskog (43,75%) i Beogradskog regiona (22,4%) i Penicillium spp. u uzorcima iz Šumadijskog regiona (26,38%). U ispitivanim uzorcima kukuruza zastupljenost Aspergillus vrsta bila je niska (0-1,78%). Mikotoksikološkim analizama ustanovljeno je prisustvo zearalenona (ZEA), deoksinivalenola (DON) i aflatoksina B1 (AFB1) u svim ispitivanim uzorcima kukuruza, izuzev što DON nije detektovan u uzorcima iz Podunavskog a AFB1 u uzorku iz Kolubarskog regiona. Ispitivani uzorci su visoko kontaminirani sa ZEA, 100% uzoraka iz Šumadijskog, Podunavskog i Kolubarskog regiona i 88,89% uzoraka iz Beogradskog regiona. Isto tako, sa DON bilo je kontaminirano 100% uzoraka iz Šumadijskog i Kolubarskog regiona i 22,2% iz Beogradskog regiona. Najveći broj AFB1 pozitivnih uzoraka ustanovljen je u Šumadijskom regionu (87,5%), dok je u Beogradskom i Podunavskom regionu ustanovljeno 55,56% i 50% AFB1 pozitivnih uzoraka, respektivno. Uopšteno razmatrajući, u ovim analizama ustanovljena je visoka zastupljenost toksigenih vrsta u svim ispitivanim uzorcima kukuruza. Isto tako, ustanovljena je visoka kontaminiranost uzoraka sa mikotoksinima ZEA, DON i AFB1, iako je samo u jednom uzorku sadržaj DON premašio dozvoljeni limit (1750 μg kg-1 ) prema zakonskoj regulativi za neprerađeni kukuruz. Zbog toga, stalne mikološke i mikotoksikološke analize zrna kukuruza neophodne su radi ocene rizika od gljivične i mikotoksin kontaminacije u lancu ishrane.",

AB  - The main purpose of the study was to determine the effect of egg mass and egg weight groups (group I eggs under 160 g, group II egg mass 160 g to 180 g and group III eggs over 180 g) on incubation results, loss of egg weight (moist) during incubation, gosling hatchability and the relative share of the gosling in the egg mass. Eggs with mass between 160 g and 180 g (group II) demonstrated the highest fertilisation rate (91.28 %) and the highest hatchability out of the number of incubated eggs (83.14 %), while the eggs from the group I (lighter than 160 g) showed the highest number of gosling hatchability out of the number of fertilised eggs (91.08 %). The lowest embryo mortality was that of the group I (5.17 % and 6.06 %), while the highest is reported for the group III (14.29 % and 16.67 %). The lowest relative loss of egg mass (moist) by day 25 of the incubation period was established for the group I eggs (10.98 %), and the highest for the group III (11.71 %), with a statistically significant (P lt 0.01) difference of -0.73 %. Other differences were not statistically significant (P>0.05). Gosling percentage in the egg mass was significantly higher (P lt 0.001) in the group III of incubated eggs (67.81 %) than in the group II (66.61 %) and the group I (65.24 %).

AB  - The European Union in 2012 banned conventional battery cages for the welfare reasons. However, transition to new housing systems uncovered some new problems, such as keel bone damage (KBD), which also could endanger welfare of laying hens. Although KBD is a research topic which attracts a growing attention in the EU, in Serbia it is still rather unknown phenomenon, even among the scientific and professional community. This research is the first attempt to determine the prevalence of KBD in laying hens in housing systems currently existing in Serbia. The results of conducted monitoring show presence of KBD on all observed farms, except the organic one. The occurrence of KBD was at an acceptable level (from the standpoint of hen welfare) in the free-range system, enriched cages without equipment and conventional battery cages (4%, 3% and 1%, respectively), while in the fully equipped enriched cages it was high (39%). One could assume that this high prevalence of KBD in this system is a consequence of a long roosting on a metal perches.

AB  - Certain investigations have been conducted in two broiler breeder flocks of Ross 308 and Cobb 500 hybrids. At the beginning of the production cycle (24 weeks of age), an average laying hens' body weight of 2680.40 g was found in the case of Ross 308 hybrid, and 2697.80 g in the case of Cobb 500 hybrid. During 42nd week of age (the middle of the production cycle), the body weight of laying hens was 3565.10 g (Ross 308) and 3599.05 g (Cobb 500), while at the end of the production cycle (61 weeks of age) the body weight of laying hens of Ross 308 hybrid was 3841.50 g, and 3850.00 g of Cobb 500. Identified differences in body weight of laying hens (17.40 g, 33.95 g, 8.50 g) in certain periods of the production cycle, as well as the difference in body weight of laying hens for the entire production cycle (23.26 g) were not statistically significant (P>0.05). More specific observation of the effect of body weight of laying hens on productive capacity of broiler breeders was determined by calculating the coefficients of phenotype correlation between the indicators studied. Thus, statistically significant (P lt 0.001, P lt 0.01, P lt 0.05) coefficients of phenotype correlation between the body weight of laying hens and the majority of production indicators have been determined, while statistically significant (P lt 0.001, P lt 0.01, P lt 0.05) correlation coefficients between the body weight of laying hens and the intensity of laying capacity for hatching and fertilized eggs have been determined, but for a shorter period of the production cycle.

Utvrđene razlike telesne težine nosillja (17.40 g, 33.95 g i 8.50 g) u određenim periodima proizvodnog ciklusa, kao i razlika u telesnoj težini nosilja za ceo proizvodni ciklus (23.26 g) nisu bile statistički signifikantne (P>0.05). Konkretnije sagledavanje uticaja telesne težine nosilja na proizvodne sposobnosti brojlerskih roditelja utvrđeno je izračunavanjem koeficijenata fenotipske korelacije između ispitivanih pokazatelja.

AB  - Examinations were conducted in two flocks of broiler parents' hybrids Ross 308 and Cobb 500. At the beginning of the production cycle (24th weeks of age) was determined that the average hens body weight of hybrid Ross 308 was 2680.40 g, and to hybrid Cobb 500 was 2697.80 g. At 42nd weeks of age (middle of the production cycle) hens body weight was 3565.10 g (Ross 308) and 3599.05 g (Cobb 500), while at the end of the production cycle (61st weeks of age) hens body weight of hybrid Ross 308 was 3841.50 g, and to the Cobb 500 was 3850.00 g. Determined differences of hens body weight (17.40 g, 33.95 g and 8.50 g) in specific periods of the production cycle, and the difference in hens body weight for the entire cycle (23.26 g) weren't statistically significant (P>0.05). Specific consideration of the impact of hens' body weight on reproductive performances of broiler parents was determined by calculating the coefficients of phenotypic correlation among the tested indicators. Thus, between hens body weight and most reproductive indicators of broiler parents were determined statistically very significant (P lt 0.001) coefficients of phenotypic correlation, while between hens body weight and the percentages of chickens feasibility from fertilized eggs were determined significant (P lt 0.001; P lt 0.01; P lt 0.05) correlation coefficients for a slightly shorter period than anticipated production cycle.

abstract = "Examinations were conducted in two flocks of broiler parents' hybrids Ross 308 and Cobb 500. At the beginning of the production cycle (24th weeks of age) was determined that the average hens body weight of hybrid Ross 308 was 2680.40 g, and to hybrid Cobb 500 was 2697.80 g. At 42nd weeks of age (middle of the production cycle) hens body weight was 3565.10 g (Ross 308) and 3599.05 g (Cobb 500), while at the end of the production cycle (61st weeks of age) hens body weight of hybrid Ross 308 was 3841.50 g, and to the Cobb 500 was 3850.00 g. Determined differences of hens body weight (17.40 g, 33.95 g and 8.50 g) in specific periods of the production cycle, and the difference in hens body weight for the entire cycle (23.26 g) weren't statistically significant (P>0.05). Specific consideration of the impact of hens' body weight on reproductive performances of broiler parents was determined by calculating the coefficients of phenotypic correlation among the tested indicators. Thus, between hens body weight and most reproductive indicators of broiler parents were determined statistically very significant (P lt 0.001) coefficients of phenotypic correlation, while between hens body weight and the percentages of chickens feasibility from fertilized eggs were determined significant (P lt 0.001; P lt 0.01; P lt 0.05) correlation coefficients for a slightly shorter period than anticipated production cycle., Ispitivanja su sprovedena na dva jata brojlerskih roditelja hibrida Ross 308 i Cobb 500.

AB  - The main goal of this work was comparative testing of fattening (body weight - gain, consumption - feed conversion and mortality) and classical (meat yield, warm and chilled carcasses, classical carcass yield - “prepared for the grill”) characteristics of two line hybrids of turkey (Hybrid Converter and Nicholas) fattened up to ten weeks (male and female specimens), i.e. up to 12, 14, 16 and 18 weeks of age (male specimens). Male specimens in relation to females had a higher growth, so that at the end of the tenth week of age average weight of male broilers was 5.22 kg (Hybrid Converter) and 4.64 kg (Nicholas). With eighteen weeks, average weight of males was 12.80 kg (Hybrid Converter) and 13.44 kg (Nicholas). Mortality till the tenth week of age (both genders of turkeys) was 5.07% (Hybrid Converter) and 4.17% (Nicholas). From the tenth to the eighteenth week of age mortality of males was 9.02% (Hybrid Converter) and 12.31% (Nicholas). Feed conversion to the tenth week of age to turkeys of the both genders was 2.47 kg (Hybrid Converter) and 2.49 kg (Nicholas). From the tenth to the eighteenth week of age feed conversion to the males was 3.72 kg (Hybrid Converter) and 3.82 kg (Nicholas). To the both hybrids of turkey, male specimens had statistically significant (P lt 0.05) lower yield of meat of warm and chilled carcasses, (carcass yield) at the age of ten weeks. Then, carcasses yield of the both sexes Hybrid Converter in relation to Nicholas was statistically significant lower (P lt 0.05). Therewith, yield of warm carcasses of males was statistically significant (P lt 0.05) lower to the hybrid Hybrid Converter in relation to the Nicholas at each age (12th, 16th, and 18th week), except 14th week because determined difference (-0.63%) wasn’t statistically confirmed (P>0.05). Similar statistical significance had been determined to the yield of chilled carcasses.

AB  - Research was conducted on New Hampshire (in further text NH) and Sombor Crested (in further text SC) breeds which were kept in semi extensive system. 56 birds of each breed were used (50 females and 6 males) in the experiment. 100 eggs from every chicken breed were used for natural hatching, and remained eggs were sold. From the total number of the naturally incubated eggs, 83 (NH) and 85 (SC) chickens were hatched, and they were used for the study of performance and related parameters.
Eggs and chickens originating from NH breed were statistically significantly heavier (P lt 0.001; P lt 0.01) compared with SC breed. Egg shape index and chicken percentage in egg weight were significantly higher at SC (P lt 0.001; P lt 0.05) compared to NH breed. Very strong positive correlation was determined between egg weight and chicken weight in both breeds. Very weak negative correlation was determined between egg weight and relative chicken intake in the egg weight. Similarly, between egg shape index and chicken weight, negative correlation coefficient was determined in both breeds. However, between egg shape index and chicken percentage, statistically significant (P lt 0.001) negative correlation coefficient was determined in NH breed. Significant (P lt 0.05) positive correlation for the same performances was determined in SC breed.

AB  - The study was conducted on hens at the age of 49 - 57 weeks to identify opportunities for replacing, with raw grain, thermally processed soybean Lana variety with a reduced level and Lydia variety with a standard level of trypsin inhibitor. The effect of using different levels of participation of both varieties of raw soybean in mixtures for layers on egg quality and eggshell quality was examined. The research was conducted according to the principle of two-factorial experiment (2 varieties x 4 levels of participation of raw soybeans). The average values of properties of the external and internal egg quality were under statistically significant influence of the level of participation of raw soybean in the mixture. Share of 8 % of raw soybeans of both varieties in diets for layers influenced significantly lower eggshape index, albumen height and Haugh's unit in relation to the mixture with a lower level of participation of raw soybeans. Yolk color and eggshell firmness were not significantly influenced by the studied factors.

AB  - The study was conducted on Isa Brown hybrid hens at the age of 49-57 weeks. The effect of using different levels of share of raw soybean of two varieties in mixtures for feeding hens on egg production, body weight, food consumption, the occurrence of defective eggs, mortality and the relative weight of the pancreas was studied. The possibility of replacing the heat-treated soybean grains, varieties Lana, with reduced trypsin inhibitor (TI) and Lydia with a standard level of TI, with raw soybean grains was examined. The research was conducted on the principle of two factorial experiment 2 x 4 (2 varieties x 4 levels of share of raw grain in the mixture) with a total of 8 diet treatments and 4 replicates per each treatment. In the first 5 weeks of the study, the differences in the number of eggs produced under the influence of tested factors were not significant. Under the influence of soybean varieties, the level of share of raw soybean and interaction of the studied factors showed significant differences (p lt 0.01) after 53 week of age. The use of soy with lower TI in the diet for laying hens resulted in a significantly greater capacity compared to standard variety. The share of raw soybean grains of 8 % in the mixtures significantly reduced the number of eggs laid. The differences in body weights, food consumption, occurrence of defective eggs and the relative weight of the pancreas were not significantly influenced by the studied factors or by their interaction effect.

Ispitan je efekat korišćenja različitog nivoa učešća sirove soje obe sorte u smešama za ishranu kokoši nosilja hibrida Isa Brown na proizvodnju jaja, telesne mase, konzumaciju hrane, pojavu defektnih jaja, mortalitet i relativnu masu pankreasa. Istraživanje je izvedeno po principu dvofaktorijalnog ogleda 2 x 4 (2 sorte soje x 4 nivoa učešća sirovog zrna u smeši) sa ukupno 8 tretmana ishrane i 4 ponavljanja po tretmanu. U prvih 5 nedelja ispitivanja razlike u broju ukupno snešenih jaja pod uticajem ispitivanih faktora nisu bile značajne. Pod uticajem sorte soje, nivoa učešća sirovog sojinog zrna i interakcije ispitivanih faktora utvrđene su značajne razlike (p lt 0,01) nakon 53. nedelje uzrasta. Korišćenje soje sa nižim nivoom TI u ishrani nosilja uticalo je na značajno bolju nosivost u odnosu na standardnu sortu soje. Sa učešćem sirovog sojinog zrna od 8 % u smešama značajno se smanjio broj ukupno snešenih jaja. Razlike u ostvarenim telesnim masama, konzumaciji hrane, pojavi defektnih jaja i relativnoj masi pankreasa koje su se javile nisu bile pod značajnim uticajem ispitivanih faktora kao ni pod uticajem njihovog interakcijskog dejstva.

AB  - Incidence of toxigenic fungi (molds) and concentration of mycotoxin aflatoxin B1 (AFB1), deoxynivalenol (DON), zearalenone (ZON) and fumonisin (FB1) were studied in the maize grains collected immediately after harvesting in 2012. A total of 29 maize samples were analyzed and the highest incidence was determined for fungal species of Rhizopus (56.41%), Aspergillus (43.66%) and Fusarium (14.97%) genera. Significantly lower incidence was obtained for species of genus Penicillium (3.31%), and especially for species of genera Acremonium (1.38%), Alternaria (0.75%) and Cladosporium (0.14%). Among toxigenic fungi Aspergillus flavus (36.69%) was the most common species of Aspergillus genus, whereas the Fusarium verticillioides with 14.69% of incidence was the predominant species of Fusarium genus. In all studied maize samples, the presence of AFB1, ZON and FB1 mycotoxins was established, except for DON which was established in 75.86% samples. AFB1 was detected in average concentration of 13.95 μg kg-1 for 44.83% of samples, and average concentration higher than 40 μg kg-1 for 55.17% of samples. The average concentrations of DON which was detected was 235 μg kg-1, while it was 98.38 μg kg-1 and 3590 μg kg-1 for the presence of ZON and FB1, respectively. Moderate positive correlation was obtained between concentrations of AFB1 and FB1 (r=0.35), while weak positive correlation was established between concentrations ZON and DON (r=0.02).

AB  - The objective of this paper is to investigate the effect of multiphase feeding, i.e. the effect of different mash feeds with multi-phase protein reduction, on growth, main carcass parts and nitrogen content in faeces of broiler chickens. The experiment was conducted on 1216 chickens of Ross 308 provenience, separated by sex. The experiment lasted for 42 days and the standard technology was used. The groups differed in a type of a mash (treatment) given in the starter period, as follows: T1 (control group) was given a mash with 23% crude proteins from day 1 to day 21; T2 - a mash with 23% proteins from day 1 to day 7, followed by a mash with 21.5% proteins given from day 7 to day 21; T3 - a mash with 23% proteins from day 1 to day 14, followed by a mash with 21.5% proteins given from day 14 to day 21; T4 - mashes changed every three days, having 23%, 22.55%, 22.10%, 21.65% , 21.20%, 20.75% and 20.30% of crude proteins, respectively. Slaughtering performance was investigated on a total of 64 broiler chickens, with eight male and eight female chickens used separately for each of the treatments. Nitrogen content in faeces was determined using the pooled sample of faeces. The obtained results showed some differences in the average daily growth of the male and female chickens when comparing the control (T1) and the experimental groups. Those differences were not statistically significant. However, when comparing the male-only groups, it was determined that the experimental group T4 had statistically significantly higher growth than T2 and T3 group. The effect of the multi-phase feeding programme on the breast, thigh and drumstick share of both male and female broilers was not significant. The applied multi-phase feeding programmes resulted in a reduction in the nitrogen content in the faeces. Considering the obtained results, it can be concluded that the multi-phase feeding programmes had no negative effect on the growth and slaughtering performances of broilers. This goes in favour of these programmes, since they can result in some positive economic and environmental effects of production.
AB  - Cilj rada je ispitivanje uticaja multifazne ishrane, odnosno različitih smeša za ishranu brojlera u kojima je sadržaj proteina višefazno smanjen, na prirast, osnovne delova trupa i sadržaj azota u fecesu. Ispitivanje je izvedeno na 1216 pilića provenijence Ross 308, razdvojenih po polu. U oglednom periodu od 42 dana primenjena je standardna tehnologija. Razlika između grupa (tretmana) bila je u tipu smeša za ishranu u starter periodu, a prema sledećem programu: T1 (kontrolna grupa) - ishrana smešom sa 23% sirovih proteina u trajanju od 1. do 21. dana; T2 - ishrana od 1. do 7. dana smešom sa 23% i od 7. do 21. dana sa 21,5% proteina; T3 - ishrana od 1. do14. dana smešom sa 23% sirovih proteina i od 14. do 21. dana sa 21,5% proteina; T4 - ishrana smešama sa dinamikom promene na svaka 3. dana, odnosno sa 23% , 22,55% , 22,10%, 21,65% , 21,20%, 20,75% i 20,30% sirovih proteina. Ispitivanje klaničnih osobina, obavljeno je na ukupno 64 brojlera, odnosno na po 8 pilića oba pola, za svaki tretman. Sadržaj azota u fecesu određen je na zbirnom uzorku fecesa. Prema dobijenim rezultatima, kod pilića muškog i ženskog pola, utvrđene razlike u prosečnom dnevnom prirastu, između kontrolne (T1) i oglednih grupa nisu bile na nivou statističke značajnosti. Međutim, poređenjem oglednih grupa međusobno, kod pilića muškog pola utvrđeno je da je ogledna T4 grupa ostvarila statistički značajno veći prirast u poređenju sa T2 i T3 grupom. Uticaj programa multifazne ishrane na prinos i udeo grudi, bataka i karabataka, kod pilića oba pola, nije bio signifikantan. Primenjeni programi multifazne ishrane rezultirali su izvesnim smanjenjem sadržaja azota u fecesu. Na osnovu dobijenih rezultata može se zaključiti da programi multifazne ishrana brojlera nisu imali negativan uticaj na prirast i klanične performanse, što ide u prilog njene primene, s obzirom da se ovim programima mogu ostvariti pozitivni ekonomski i ekološki efekti proizvodnje.

abstract = "The objective of this paper is to investigate the effect of multiphase feeding, i.e. the effect of different mash feeds with multi-phase protein reduction, on growth, main carcass parts and nitrogen content in faeces of broiler chickens. The experiment was conducted on 1216 chickens of Ross 308 provenience, separated by sex. The experiment lasted for 42 days and the standard technology was used. The groups differed in a type of a mash (treatment) given in the starter period, as follows: T1 (control group) was given a mash with 23% crude proteins from day 1 to day 21; T2 - a mash with 23% proteins from day 1 to day 7, followed by a mash with 21.5% proteins given from day 7 to day 21; T3 - a mash with 23% proteins from day 1 to day 14, followed by a mash with 21.5% proteins given from day 14 to day 21; T4 - mashes changed every three days, having 23%, 22.55%, 22.10%, 21.65% , 21.20%, 20.75% and 20.30% of crude proteins, respectively. Slaughtering performance was investigated on a total of 64 broiler chickens, with eight male and eight female chickens used separately for each of the treatments. Nitrogen content in faeces was determined using the pooled sample of faeces. The obtained results showed some differences in the average daily growth of the male and female chickens when comparing the control (T1) and the experimental groups. Those differences were not statistically significant. However, when comparing the male-only groups, it was determined that the experimental group T4 had statistically significantly higher growth than T2 and T3 group. The effect of the multi-phase feeding programme on the breast, thigh and drumstick share of both male and female broilers was not significant. The applied multi-phase feeding programmes resulted in a reduction in the nitrogen content in the faeces.

AB  - Analysis results regarding the external traits of breeding eggs quality originating from Leghorn breed reared in semi extensive system are given in this research. Research was done on the 55 egg sample, divided in to two categories according to weight: I group - eggs weighing up to 60 g (≤ 60 g) and II group - eggs weighing over 60 g (> 60 g). Aim of this research was to analyze the influence of weight group to base quality traits of eggs, such as weight, length, width, shape index in above mentioned breeding system. Obtained results point the fact that Leghorn breed in semi extensive breeding system achieves very satisfying results in terms of the base external quality characteristics of the eggs. Results of conducted research show that more attention should be given to the quality of eggs for planting, especially for pure breeds, then towards breeding goals with aim to improve their productive - reproductive traits, therefore preserving genetic potential of different breeds, species and races of poultry.
AB  - U radu su izloženi rezultati ispitivanja spoljašnjih osobina kvaliteta priplodnih jaja poreklom od Leghorn rase kokoši gajene u poluekstenzivnom sistemu držanja. Ispitivanja su izvršena na uzorku od po 55 jaja, podeljenih u dve težinske grupe i to: I grupa - jaja mase do 60 g (≤ 60 g) i II grupa - jaja mase preko 60 g (> 60 g). Cilj istraživanja je bio da se ispita uticaj težinske grupe na osnovne pokazatelje kvaliteta jaja, kao što su masa, dužina, širina i indeks oblika jaja u navedenom sistemu držanja. Dobijeni rezultati ukazuju na činjenicu da leghorn rasa kokoši u poluekstenzivnom sistemu gajenja ostvaruje zadovoljavajuće rezultate u pogledu osnovnih karakteristika spoljašnjeg kvaliteta jaja.

AB  - In order to make comparative examination of lying eggs capacity, an experiment was carried out. It lasted from 19th to 63rd week of age. Examination included two hens’ hybrids Shaver 579 and Hisex Brown. For both examined hybrids, similar conditions of growing and feeding technology were provided. For the whole period of egg production, average values and variability of weekly number of eggs per hen for Shaver 579 was 5.72, and Hisex Brown had a little higher weekly egg production-5.99 eggs. The greatest part of eggs per hen was in 11th week of production in both examined provenience. In both examined light line hybrids, statistically significant difference was determined between age of hens and average weekly egg production per hen.

AB  - In this research influence of the rooster body weight on reproductive performance of broiler parents was examined for Ross 308 and Cobb 500 hybrids. At the beginning of the productive cycle (24 weeks of age) for roosters Ross 308 hybrids average body weight of 3,030.00 g has been determined, while for Cobb 500 rooster average body weight was 3,045.00 g. In the 42nd week of age (middle of productive cycle), body weight of Ross 308 roosters was 4,306.00 g and 4,323.00 g for Cobb 500 roosters, while at the end of productive cycle in the 61st week of age Ross 308 hybrids had average 4.908,00 g and Cobb 500 had 4,918.50 g. Determined differences in body weight of roosters (15.00 g, 17.00 g and 10.50 g) in specific periods of productive cycle, as well as difference in body weight for the entire productive cycle (19.97 g) were not statistically significant (P>0.05). Between rooster body weight and fertilized eggs laying intensity positive statistically significant (P lt 0.001; P lt 0.01; P lt 0.05) correlation coefficients were determined. Between rooster body weight and hatchability percentage of the chicks positive statistically significant (P lt 0.001; P lt 0.01; P lt 0.05) correlation coefficients were determined for both hybrids. However, based on correlation coefficient it has been determined that rooster body weight had positive influence on laying intensity of fertilized eggs till 58th week of age (Ross 308) and 60th week of age (Cobb 500), while on hatchability of chicks it had positive influence till 58th week of age for both hybrids.
AB  - Ispitivanje uticaja telesne težine petlova na reproduktivne performanse brojlerskih roditelja sprovedeno je kod hibrida Ross 308 i Cobb 500. Na početku proizvodnog ciklusa (24. nedelja starosti) kod hibrida Ross 308 utvrđena je prosečna telesna težina petlova 3.030,00 g, a Cobb 500 3.045,00 g. U 42. nedelji starosti (sredina proizvodnog ciklusa) telesna težina petlova iznosila je 4.306,00 g (Ross 308) i 4.323,00 g (Cobb 500), dok je na kraju proizvodnog ciklusa (61. nedelja starosti) telesna težina petlova kod hibrida Ross 308 iznosila 4.908,00 g, a hibrida Cobb 500 4.918,50 g. Utvrđene razlike telesne težine petlova (15.00 g, 17.00 g i 10.50 g) u određenim periodima proizvodnog ciklusa, kao i razlika u telesnoj težini petlova za ceo proizvodni ciklus (19.97 g), nisu bile statistički signifikantne (P>0.05). Između telesne težine petlova i intenziteta nosivosti oplođenih jaja utvrđeni su pozitivni statistički značajni (P lt 0.001; P lt 0.01; P lt 0.05) koeficijenti korelacije do 50. nedelje starosti kod hibrida Ross 308, odnosno 53. nedelje kod roditeljskog jata hibrida Cobb 500, a između telesne težine petlova i procenta izvodljivosti pilića utvrđeni su pozitivni statistički značajni (P lt 0.001; P lt 0.01; P lt 0.05) koeficijenti korelacije do 51. nedelje starosti kod oba ispitivana hibrida. Međutim, na osnovu koeficijenata korelacije utvrđeno je da je telesna težina petlova pozitivno uticala na intenzitet nosivosti oplođenih jaja do 58. nedelje starosti (Ross 308), tj. 60. nedelje starosti (Cobb 500), a na izvodljivost jednodnevnih brojlerskih pilića do 58. nedelje starosti kod oba ispitivana roditeljska jata.

Between rooster body weight and fertilized eggs laying intensity positive statistically significant (P lt 0.001; P lt 0.01; P lt 0.05) correlation coefficients were determined. Between rooster body weight and hatchability percentage of the chicks positive statistically significant (P lt 0.001; P lt 0.01; P lt 0.05) correlation coefficients were determined for both hybrids. However, based on correlation coefficient it has been determined that rooster body weight had positive influence on laying intensity of fertilized eggs till 58th week of age (Ross 308) and 60th week of age (Cobb 500), while on hatchability of chicks it had positive influence till 58th week of age for both hybrids., Ispitivanje uticaja telesne težine petlova na reproduktivne performanse brojlerskih roditelja sprovedeno je kod hibrida Ross 308 i Cobb 500. Na početku proizvodnog ciklusa (24. nedelja starosti) kod hibrida Ross 308 utvrđena je prosečna telesna težina petlova 3.030,00 g, a Cobb 500 3.045,00 g. U 42. nedelji starosti (sredina proizvodnog ciklusa) telesna težina petlova iznosila je 4.306,00 g (Ross 308) i 4.323,00 g (Cobb 500), dok je na kraju proizvodnog ciklusa (61. nedelja starosti) telesna težina petlova kod hibrida Ross 308 iznosila 4.908,00 g, a hibrida Cobb 500 4.918,50 g. Utvrđene razlike telesne težine petlova (15.00 g, 17.00 g i 10.50 g) u određenim periodima proizvodnog ciklusa, kao i razlika u telesnoj težini petlova za ceo proizvodni ciklus (19.97 g), nisu bile statistički signifikantne (P>0.05). Između telesne težine petlova i intenziteta nosivosti oplođenih jaja utvrđeni su pozitivni statistički značajni (P lt 0.001; P lt 0.01; P lt 0.05) koeficijenti korelacije do 50. nedelje starosti kod hibrida Ross 308, odnosno 53. nedelje kod roditeljskog jata hibrida Cobb 500, a između telesne težine petlova i procenta izvodljivosti pilića utvrđeni su pozitivni statistički značajni (P lt 0.001; P lt 0.01; P lt 0.05) koeficijenti korelacije do 51. nedelje starosti kod oba ispitivana hibrida. Međutim, na osnovu koeficijenata korelacije utvrđeno je da je telesna težina petlova pozitivno uticala na intenzitet nosivosti oplođenih jaja do 58. nedelje starosti (Ross 308), tj. 60. nedelje starosti (Cobb 500), a na izvodljivost jednodnevnih brojlerskih pilića do 58. nedelje starosti kod oba ispitivana roditeljska jata.

AB  - In this paper results of research of external quality traits of the fertile eggs of Partridge Italian bread in semi extensive system are shown. Research was conducted on sample of 64 eggs, divided in to two groups according to the weight. First group was eggs weighing up to the 60 g (≤ 60 g) and second group eggs weighing above 60 g (> 60 g). Aim of the research was to determine influence of the weight of the eggs to the external quality traits of fertile eggs, such as weight, length, width and shape index of the eggs in quoted breeding system. Obtained result points to the fact that Partridge Italian in semi extensive system achieves satisfying results in regard of the basic external characteristics of egg quality. Results of the conducted research show that it is needed to give higher attention to the quality of eggs used for planting, to the breeding direction, improvement of the productive and reproductive traits, and therefore to preservation of the genetic potential of different breeds and strains of chicken.

AB  - The quality of poultry feed is an important precondition to achieve optimal production results, and the preservation of the health status of animals, especially in intensive livestock production, hence it is necessary to control both raw materials and finished feed mixtures. The presence of fungi (moulds) in food for animals is a natural phenomenon, not an exception. Sources of contamination of poultry feed with fungi and resulting mycotoxins vary, starting with raw materials (e. g. corn as the most common component) during harvest and transport, during storage of raw materials and finished products, as well as in the production process and manipulation of poultry feed. Mineral adsorbents are increasingly used in poultry production, especially in the nutrition of various types and categories of poultry, to control fungal contamination. Using different mineral adsorbents in poultry nutrition can prevent the losses due to mycotoxicosis. It can also prevent appearance of toxic residues in poultry products, improve production and reproductive ability of birds, and contribute to improving the quality of poultry products. In addition, the use of mineral adsorbents in poultry feeds has application in neutralising the harmful effects of mycotoxins in buildings where poultry is reared.

AB  - Objective of the research was to investigate the effect of phase nutrition, i.e. different mixtures used in broiler nutrition with phase reduction of protein cotnent during starter period on production peformances of fattening chickens of different genotypes and on nitrogen content in faeces. Differences between groups (treatments) were in the type of mixtures use din starter period, and according to the following program: T1 (control group) - nutrition consisted of mixtures with 23% of proteins in duration from day 1 to 21; T2 - from day 1 to 14, mixture containing 23% of protein was used, and from day 14 to 21, mixture with 20% of proteins; T3 - from day 1 to 7, mixture was used containing 23% of protein and from day 7 to 21, mixture with 20% of proteins; T4 - nutrition with mixture containing 20% of proteins in duration from day 1 to 21. During the trial period (from day 1 to 21) production parameters were followed. Nitrogen content was determined in a collective faeces sample. Results showed that chickens of different genotypes expressed different sensitivity to protein restriction. Comparing the trial groups with the control in the third week, in chickens of Ross 308 provenience significantly lower body weight was registered only in chickens of T4 group with the highest protein reduction. In Cobb 500 chickens, significantly lower body weight was determined in T3 and T4 trial groups. In case of both hybrids, in T2 group, slightly lower body weight was established, but without statistically significant difference compared to the control. Feed conversion in both genotypes was the highest in T3 and T4 treatments. The program of phase nutrition resulted in decrease of the nitrogen content in faeces. Based on obtained data it can be concluded that applied nutrition treatments with drastic protein reduction during starter period in both genotypes had negative effect on production performances. Therefore, the composition and dynamics of mixture changes must be taken into consideration when formulating the program of phase nutrition, in order to achieve both goals - decrease of protein content in feed with simultaneous diminished nitrogen excretion and achieving good results.
AB  - Cilj istraživanja je da se ispita uticaj fazne ishrane, odnosno različitih smeša za ishranu brojlera u kojima je sadržaj proteina smanjen fazno u starter periodu na proizvodne osobine tovnih pilića različitog genotipa i sadržaj azota u fecesu. Razlika između grupa (tretmana) bila je u tipu smeša u starter periodu, a prema sledećem programu: T1 (kontrolna grupa) - ishrana smešom sa 23% proteina u trajanju od 1. do 21. dana; T2 - ishrana od 1. do 14. dana smešom sa 23% proteina i od 14. do 21. dana sa 20% proteina; T3 - ishrana od 1. do 7. dana smešom sa 23% proteina i od 7. do 21. dana sa 20% proteina; T4 - ishrana smešom sa 20% proteina u trajanju od 1. do 21. dana. U oglednom periodu (od 1. do 21. dana) praćeni su proizvodni parametri. Sadržaj azota u fecesu određen je na zbirnom uzorku. Rezultati su pokazali da su pilići različitih genotipova ispoljili različitu osetljivost na restrikciju proteina. Poređenjem oglednih grupa sa kontrolnom u trećoj nedelji, kod pilića provenijence Ross 308 konstatovano je da je signifikantno manju telesnu masu ostvarila samo T4 grupa sa najstrožijom redukcijom proteina. Kod provenijence Cobb 500 signifikantno manja telesna masa utvrđena je za T3 i T4 oglednu grupu. Kod oba hibrida za T2 oglednu grupu utvrđena je nešto manja telesna masa, ali bez statistički značajne razlike u poređenju sa kontrolnom. Konverziju hrane kod oba genotipa imala je najveće vrednosti za T4 i T3 tretman. Programi fazne ishrane rezultirali su smanjenjem sadržaja azota u fecesu. Na osnovu dobijenih rezultata može se zaključiti da su primenjeni tretmani ishrane sa drastičnom restrikcijom proteina u starter periodu kod oba genotipa imali negativan uticaj na proizvodne performanse. Zbog toga se prilikom formulisanja programa fazne ishrane strogo mora voditi računa o sastavu i dinamici promene smeša, a kako bi se postigla oba cilja - smanjenje sadržaja proteina u hrani uz smanjenu ekskreciju azota i postizanje dobrih proizvodnih rezultata.

AB  - The use of betaine can influence the resistance, production performance and quality of broiler carcass, and potentially it can reduce the need for choline and methionine in food due to the mutual correlation of these three substances in the organism. Objective of the paper was to investigate the effect of full substitution of added DL-methionine with betaine in diets for broilers on production and slaughter parameters in conditions of optimal amount of choline in the feed. Study was carried out on 1725 one day old broiler chickens of Cobb 500 hybrid divided into 3 groups: Control group (C) fed complete forage mixtures with usual addition of DL methionine and two trial groups where methionine was substituted by 1g (B1group), and by 2g of betaine per kilogram of mixture (B2 group). Research results indicate that the full substitution of supplemented methionine with betaine in feed can have positive and negative impact in broiler fattening. Negative effects on final body mass, gain and feed conversion were determined in broilers fed mixtures where 1g of synthetic methionine was replaced with 1g of betaine preparation, and at the same time positive influence on mortality was observed, especially in broilers fed diets containing 2g of betaine. Production index showed no significant differences between trial groups, as well as studied broiler carcass quality parameters.
AB  - Upotreba betaina može imati uticaja na otpornost, proizvodne performanse i kvalitet trupa brojlera, a potencijalno može smanjiti i potrebu za holinom i metioninom u hrani usled međusobne povezanosti ove tri supstance u organizmu. Cilj rada je da se ispita uticaj kompletne zamene dodatog DL-metionina betainom u obrocima brojlera na proizvodne i klanične parametre u uslovima optimalne količine holina u hrani. Istraživanje je izvedeno na 1725 jednodnevnih brojlerskih pilića hibrida Cobb 500 podeljenih u 3 grupe: kontrolnu grupu (C) hranjenu potpunim krmnim smešama sa uobičajnim dodatkom DL metiona i dve ogledne grupe kojima je umesto metionina dodavan 1gram (B1grupa), odnosno 2g betaina po kilogramu smeše (B2 grupa). Rezultati istraživanja ukazuju da potpuna zamena dodatnog metionina betainom može imati i pozitivne i negativne efekte u tovu brojlera. Utvrđen je negativan uticaj na završnu telesnu masu, prirast i konverziju hrane kod brojlera kojima je u smešama 1g sintetičkog metionina zamenjen sa 1g betainskog preparata, ali i pozitivan uticaj na smanjenje mortaliteta, posebno kod brojlera sa 2g betaina u hrani. Proizvodni indeks se nije značajnije razlikovao između oglednih grupa, a takođe i ispitivani parametri kvaliteta trupa brojlera.

AB  - This study involves the analysis of two breeds [Naked Neck (NN) and Svrljig chickens (Sv)], that is, strains [White Naked Neck (WNN) and Black Svrljig strain (BSv)] of chickens (birds) of both sexes reared under a semi-intensive system until day 84 of age. At 28 days of age, the test birds were kept in a litter housing system (about 8 birds/m(2)), following which they were provided a free-range paddock at 4 m(2)/bird. The following parameters were evaluated in the two strains and sexes of broilers (totalling 56 chickens) aged 84 days: body weight at slaughter, carcass weight, yields of breasts, thighs, drumsticks, wings, pelvis, back, head, neck, feet, abdominal fat and giblets. At the end of the fattening period, the test broilers of both sexes of the WNN strain had higher values (P lt 0.05) for yield of drumsticks and thighs (34.20 to 33.93%), a statistically lower yield (P lt 0.01) of the back and pelvis (26.34 to 26.97%), and a somewhat higher live body weight (1587.07 to 1562.28 g). The difference was not statistically significant (P>0.05); however, a similar yield was obtained for ready to grill carcass (61.73 to 61.99%) when compared with the black Svrljig strain. The differences obtained were not statistically significant (P>0.05). In addition to the genotype (breed, strain), broiler sex had a statistically significant effect (P lt 0.001; P lt 0.01; P lt 0.05) on body weight, carcass yield, yields of drumsticks and thighs, wings, head, feet, giblets and abdominal fat. Specifically, male broilers were found to have higher live body weight (1669.29 to 1480.07 g), carcass weight (1342.86 to 1198.28 g), yields of head (5.13 to 4.39%), drumsticks and thighs (34.26 to 33.96%), feet (5.39 to 5.06%) and giblets (6.46 to 6.31%), whereas the relative yields of carcass (conventional processing (CP): 80.96 to 80.44%; ready to roast (RR): 73.02 to 72.19%; ready to grill (RG): 62.30 to 61.45%), wings (14.06 to 13.76%) and abdominal fat (1.13 to 1.07%) were higher in female broilers.

AB  - Here we have results of examination of eggs quality in two light line hybrids of chickens (Hisex Brown and Shawer 579). At the end of every four-week period an examination of external qualities of eggs was carried out. The examination was carried out on the sample of 30 eggs for each hybrid. There were total of ten examinations. The aim of these researches was to examine effects of genotype and age of hens on deformation of egg shell in 10-month period. Obtained measuring average of egg shell deformation for Shawer 579 was 26.27/1000mm and it was a little higher than deformation in Hisex Brown (25.82/1000mm). On the basis of the research, it was noticed that with the age of hen, deformation of egg shell increases, too. Higher range of variability in egg shell deformation in 4-week periods of examinations was found in Hisex, but differences were not significant. Accordingly, differences between obtained results for egg shell deformation in examined hens were very small.
AB  - U radu su izloženi rezultati ispitivanja kvaliteta jaja dva laka linijska hibrida kokoši (Hisex Brown i Shaver 579). Krajem svakog 4-nedeljnog perioda obavljeno je ispitivanje spoljašnjih osobina kvaliteta jaja. Ispitivanje je vršeno na uzorku od 30 jaja za svaki hibrid. Ukupno je izvršeno 10 ispitivanja. Cilj ovih istraživanja, bio je da se ispita uticaj genotipa i uzrasta nosilja na deformaciju ljuske kokošijeg jajeta u periodu od 10 meseci. Dobijeni prosek merenja deformacije ljuske jajeta za Shaver 579 nosilje iznosio je 26,27/1000 mm i bio je nešto veći u odnosu na deformaciju koju je imao Hisex Brown (25,82/1000 mm). Na osnovu istraživanja, zapaženo je da se sa uzrastom nosilja deformacija ljuske jajeta povećavala. Veći raspon variranja deformacije ljuske jajeta po 4-nedeljnim periodima ispitivanja imale su nosilje Hisex, ali razlike nisu bile signifikantne. Prema tome, razlike između dobijenih rezultata za deformaciju ljuske kokošijih jaja kod ispitivanih nosilja, bile su zanemarljivo male.
