AB  - The aim of this study was to examine the effect of using tannin supplement in ration for mid-lactation dairy cows (90 +/- 17 days in milk) and the number of lactation on metabolic profile parameters values. Additionally, the effect of tannin supplementation on cows' production characteristics in the 2nd lactation was evaluated. Research was conducted on 80 Holstein cows divided into two groups of 40 cows (control and experimental group) that included 16 cows in 2nd and 12 in 3rd and 4th lactation. The tannin supplement Tanimil SCC (40 g/cow/day; 40% of tannins) was added in the total mixed ration (TMR) of experimental group, while the control group of cows was fed ration without the tannin supplement. The trial lasted 60 days. Dairy cows, fed diet supplemented with tannin, had markedly lower values (P lt 0.05) of B-hydroxybutyrate concentration (0.79 vs. 0.96 mmol/L) and lower blood urea concentration (5.89 vs. 6.93 mmol/L). Difference in the blood glucose concentrations (3.92 vs. 3.89 mmol/L) was not significant. The lactation number had no significant effect on values of metabolic profile parameters (concentration of glucose, B-hydroxybutyrate and urea). The effect of interaction of lactation number and tannin supplement on the values of examined parameters of metabolic profile was not significant. Supplementation of tannin in the diet for cows in the second lactation, had a positive effect (P lt 0.05) on the milk yield (4.42%) and yield of 4% fat corrected milk (FCM, 5.24%). The use of tannin, improved concentration (3.20 vs. 3.12%) and yield (from 1.16 to 1.24 kg/day) of milk protein (P lt 0.05). Addition of tannin also improved concentration and yield of milk fat, as well as the concentration of lactose. The supplementation of Tanimil SCC to mid-lactation dairy cows had a positive impacts on reduction of blood content of B-hydroxybutyrate and urea, and improved productive performances of cows in the second lactation.

AB  - Visual evaluation and recognition of dairy traits of cows are preliminary indicators of milk yield, longevity, and reproductive ability of the individual animal, which is very important from the aspect of the economics of milk production. The deficiencies in the fundament traits lead to poor production, poor health and premature culling of cows from the herd. The paper examines the frequency of preferred scores of a certain trait in the first calving heifers according to the housing method (animals reared by individual agricultural producers and farm animals) and their origin (domestic and imported animals), as well as the impact of these two factors on the observed properties. Four fundament traits were analysed: the position of the hind legs, the development of the hocks/joints, the pastern joints and the height of the feet on a total of 954 first-calving Simmental heifers. Observed by the housing method, the higher frequency of the preferred scores for all of the fundament traits, was achieved by the farm cows, while according to the origin of the cows, the higher frequency of the preferred scores for all of the fundament traits was realized by imported animals in relation to domestic cows. The influence of the factors of the housing method and origin of animals examined by χ2 test on all the tested linear scores (frequency of scores) of the fundament traits was statistically very significant (p≤0.001), while the analysis of the variance (F test) determined high significance (p≤0.001) of the interaction between the origin and housing method on the height of the feet, as well as significant effect (p≤0.05) on the position of the hind legs, while on other linear scores of the fundament traits it did not exhibit statistical significance (p>0.05).

AB  - The objective of this study was to determine the frequency of the kappa-casein and beta-lactoglobulin genotypes in the Simmental cattle in Serbia and compare it with the frequency according to the Hardy-Weinberg equilibrium law. Blood samples were taken from a total of 157 cows of the Simmental breed in Toplica and Rasina districts. Of the 157 cows included in this study, the AA kappa-casein genotype was found in 53 cows, which makes a frequency of 33.80%, the AB genotype in 81 cows or 51.60% and the BB genotype in 23 cows or 14.60%. The allelic frequency A was 59.60%, while allele B had a frequency of 40.40%. In regard to the frequency of genotypes and beta-lactoglobulin alleles for the total studied population of cows obtained for AA, AB and BB genotypes for beta-lactoglobulin, was 33.10%, 49.70% and 17.20%, respectively, which means that 52 animals had genotype AA, 78 genotype AB and 27 genotype BB. The frequency of alleles A and B resulting from the incidence of genotypes was 58.00% for allele A and 42.00% for allele B. The specified frequencies for both protein fractions statistically differed significantly from the frequency according to the Hardy-Weinberg equilibrium law, which confirmed the absence of equilibrium in the examined population.

AB  - Problems with legs and various forms of lameness of cows, in intensive milk production, are the third significant problem occuring in this production, after mastitis and reproductive disorders, both globally and in our country. The paper analyzes the incidence of the deformation of legs of 145 cows of the Simmental breed in the Kolubara region, and the influence of paragenetic factors (housing/holding and type of stall/bedding and lactation) on the incidence of deformations. The obtained results show that, of the total number of cows assessed, 3.45% had 'X' position of the front legs, 14.8% had a 'X' position of the hind legs. The convergent position of the front legs was recorded in 35.86%, and divergent in 8.28% of animals. The convergent position of the hind legs was observed in 16.55% of cows, and divergent in 2.76%. The outward position of the front legs was observed in 4.14% of cows, inward position in 11.03%, and broad position in 4.14% of studied cows. Also, 17.24% of the cows had a so called sable like position of hind legs, and 7.59% showed steap angle of hind legs. The pronounced soft front leg pasterns were observed in 7.59% of the cows, and the soft pasterns of the hind legs in 33.79% of the total number of observed cows. The observed changes in the ankles in the shape of swelling were recorded in 1.38% of cattle on the carpal joint and 2.76% on the tarsal ankle. The damaged shoulder and body joint (scabbed shoulder) was observed in 43.45% of the total number of cows evaluated. Scores for the front and hind legs front, back and side views, varied at different levels of significance under the influence of the type of stall/bedding, while the scores for the condition of the hind leg pasterns varied highly significantly (p lt 0.001) under the influence of the type of stall/bedding. The scores for the front leg pasterns and scores for shoulder and body joint were not significant (p> 0.05) depending on the type of stall/bedding and the method of housing/holding of cows.

Od ukupnog broja ocenjenih krava 3,45 % je imalo 'X' stav prednjih nogu, 14,8% je imalo 'X' stav zadnjih nogu. Konvergentan stav prednjih nogu imalo je 35,86%, a divergentan 8,28%. Konvergentan stav zadnjih nogu imalo je 16,55% krava, a divergentan 2,76%. Isturen stav prednjih nogu imalo je 4,14% krava, podvučen 11,03%, a širok stav 4,14%. Sabljast stav zadnjih nogu imalo je 17,24% krava, a stubast 7,59%. Izražene mekane kičice prednjih nogu imalo je 7,59% krava, a mekane kičice zadnjih nogu imalo je 33,79% od ukupnog broja ocenjenih krava. Uočene promene na zglobovima u vidu otoka imalo je 1,38% krava na karpalnom zglobu i 2,76% na tarzalnom zglobu. Narušen spoj lopatice i tela (odvaljena plećka) imalo je 43,45% od ukupnog broja ocenjenih krava. Ocene za stavove prednjih i zadnjih nogu posmatrano spreda, otpozadi i sa strane varirale su na različitom nivou značajnosti pod uticajem tipa ležišta, dok ocene za stanje kičica na zadnjim nogama su vrlo visoko značajno (p lt 0,001) varirale pod uticajem tipa ležišta. Ocene za kičice prednjih nogu i ocene za spoj lopatice i trupa, nisu značajno (p>0,05) zavisile od tipa ležišta i načina držanja krava.",

AB  - This research paper gives an analysis on the size of world's domestic buffalo populations, their milk production and the size of buffalo population in Serbia. Population of domestic buffalo in the world is constantly increasing so that in 2013 there were 199 783 549 individuals, out of which in India in the same year they raised 57.77% of buffalo world population, in Pakistan 18.87%, and in China 11.64%. The share of total world production of buffalo milk in total world milk production in 2012 was 12.92 % or 97 417 135 t out of which 67.76% was produced in India. In Serbia buffalo is raised in the regions of Raška (about 1000 individuals) and Kosovo. Populations of buffalo in central Serbia show a tendency of decreasing in size what was the reason to start a programme of in situ conservation 10 years ago. On the sample of buffalo population encompassed by the programme of conservation the body measures were analysed indicating that the population of buffalo is quite unequalised and that average values obtained for exterior measures are similar to the results obtained by the authors of earlier period for the population of buffalo in the area of former Yugoslavia.

U Srbiji bivoli se gaje u području Raške oblasti (oko 1000 bivola) i na području Kosova. Populacija bivola u centralnoj Srbiji ima tendenciju smanjenja veličine, zbog čega je pre 10 godina počeo da se sprovodi program konzervacije. Na uzorku populacije (37 bivolica) obuhvaćene programom in situ konzervacije utvrđene su prosečne vrednosti za telesne mere. Visina grebena bivolica u populaciji koja je merena bila je 125,97 cm, visina krsta 126,98cm, dužina trupa 142,19cm, dubina grudi 68,75 cm, širina grudi 44,48cm, a obim grudi 184,25 cm. Populacija bivolica je bila dosta neujednačena što ukazuje na odsustvo odgajivačko-selekcijskog rada kod bivola u Srbiji u prethodnim decenijama.

AB  - The quality and yield of milk, and therefore of dairy products as well, depends directly on their protein composition. Milk gene proteins represent structural locuses that are functionally associated with milk production. In cattle selection a special importance is attached to the variability of kappa casein (kappa-CN) as one of the four casein milk proteins. Genotypes of 21 Simmental breed cows, 20 crossbred cows obtained by crossing of Simmental and Red Holstein breed, and 25 cows of autochthonous Busha breed were determined for kappa casein by restriction fragment length polymorphism analysis (PCR-RFLP) of amplified DNA. The kappa-CN genotype frequencies for Simmental breed were: 42.8; 47.6 and 9.6 % for AA, AB and BB genotype, for crossbreds: 75.0; 25.0 and 0.0% and for Busha individuals: 41.7; 50.0 and 8.3 %, respectively. Frequencies of A and B alleles, assessed on the basis of genotypic frequencies were 0.667 and 0.333 for Simmental breed, 0.875 and 0.125 for crossbreds and 0.667 and 0.333 for autochthonous Busha cattle breed, respectively. For confirming the phenotypic variability of milk yield in standard lactation, yield of milk fat and the content of milk fat per kappa-CN genotypes within breeds observed the fixed model which included the breed effect, lactation in order and effect of kappa-CN genotype (AA, AB and BB) was used. The kappa-CN genotype statistically significantly (p  lt = 0.05) influenced milk yield and highly significantly (p  lt = 0.01) milk fat yield, while the content of milk fat was not statistically significantly (p >0.05) influenced in examined animals.

AB  - The conducted research was aimed at constructing equations of selection index that would be used in the selection of the Holstein-Friesian breed animals in Serbia. The construction of the selection index includes the most important milk traits observed in standard lactation: milk yield (MY305), milk fat content (% MF305) and protein content (% MP305). The variance and covariance necessary for the construction of selection index are calculated using the mixed model by the method of least squares. The economic value of traits is expressed as a ratio of relative changes in costs per unit of traits included in the selection index. Livestock included in the research produced, in the first standard lactation, an average of 7681 kg of milk with 3.58% milk fat and 3.28% protein. The equation of the selection index presented in the paper is selected from the group of equations of selection index, as an equation with the highest correlation between the equation and the aggregate genotype, which amounted to 0.2156.

AB  - The objective of this study was a construction of selection index on the basis of whose score the cows could be graded during their selection and formation of parent pairs. The most important milk yield traits in standard lactation: milk yield (PM305), milk fat content (%MM305) and protein content (%MP305) were included in the construction of selection index. Variances and covariances deemed necessary for construction of selection index were calculated by use of the mixed model of the Least Squares method. Economic value of the traits was expressed as a relationship of relative cost changes per unit of the traits included in the selection index. The individuals included in the trial on average produced 8261 kg milk with 294.14 kg milk fat and 270.07 kg protein in standard lactation. Equation of selection index used in this study was chosen from a set of selection index equations, as an equation having the highest correlation between the equation and aggregate genotype which amounted to 0.4275.

AB  - This paper presents the most important production results obtained for the population of Simmetal breed raised in majority of the European countries which with a total population of about 9 million animals rates as the second biggest important cattle breed in Europe. Breeding goals from previous period were analysed along with newly defined  breeding goals in some Simmental breed populations. Current mean values for milk yield of Simmental cows in standard lactation in the European countries range from 5500 to 7500 kg. Depending on the Simmental breed population in most countries a breeding goal set for first lactation cows is milk yield of 5500 or 6000 kg with 4.0% milk fat and 3.5% protein, while in cows who finished their third lactation required milk production is more than 7000 kg for Simmental breed, over 8000 kg for Simmental breed with share of Red and White Holstein genes and over 8500 kg for Montbeliard breed. A special emphasis is given on the prolonging of the duration of life and production span. During life span the demand is to produce minimum 30 000 kg milk/cow. This demand can be realised if functional traits in breeding goal participate with over 40 %  with proper implementation of improvement programme. As for the traits that are significant for meat production, depending on the population, defined breeding goal for daily liveweight gain are values above 1500 g/day (i.e. 1400 g /day) for Simmental male bullcalves.

AB  - Aim of this research was to determine the influence of lactation order on fertility, milk yield and Sanska goat milk chemical composition. Monitoring of mentioned parameters was conducted from first till third lactation. It has been concluded that from first till third lambing fertility was increasing. In first lactation goats produced significantly (P lt 0,01) less milk (561,13 kg), than goats in second (654,25 kg) and third (743,20 kg) lactation. Amount of milk fat and proteins was increasing from first till third lactation. Research has shown that lactation order, goat age has significant influence on fertility, milk yield and milk chemical composition.

AB  - In this paper Sanska goat reproductive parameters after the first kidding are shown as well as influence of birth type on kid body weight at birth. At first insemination average age of young goats was 252 days. Average gestation period for goats that carried twins was 150.19 days and for goats that carried singles 151.10 days. Determined difference in gestation length of 0.91 days in favor of goats that carried singles was not statistically significant (P0.05). Goat fertility after first kidding was 164.70%. Kid body weight at birth was analyzed based on birth type (singles-twins). Singles had higher body weight at birth than twins by 0.91kg (34.60%) which was statistically very significant (P lt 0.01). Average body weight of singles was 3.54kg, and twins 2.63kg, twins were approximately 74.29% of body weight of singles. Gender based differences at birth in body weight were present in favor of male kids, but they were not statistically significant (P0.05). Based on obtained results in this research we can conclude that the results which were obtained for researched parameters are within average limits for Sanska goat breed.

AB  - The aim of this research was to determine if there are differences in sexual reaction of the grown sheep II de frans breed depending on the body weight of treated eves during induction and synchronization of estrus with fluorogestonacetate (FGA) + PMSG in anoestrus season. Total number of 262 eves was treated and they were divided in to three groups. The first group consisted of the sheep whose body weight was from 40 to 50kg, the second group of the sheep whose weight was from 50-60kg and the third group of the sheep whose weight was above 60kg. Each group received sponges of FGA. After removal of the sponges all sheep received intramuscular injection of 500 i.u of PMSG. The 'Sugonal' prepared by Veterinary institute Subotica was used. After two days the insemination was conducted. The results show that from first group 43.78% sheep lambed, from second group 46.66% and from third group 59.32%. Average sheep fertility after treatments was for the first group 113.28%, 118.37% for the second group and 137.14% for the third group. The ratio of singles, twins and triplets was for the first group 72:28:0 %, for the second group 70.69:24.14:5.17%, and for the third group 47.92:45.83:6.25%. Determined differences between number of lambed sheep and treated sheep, fertility and number of twins, as well as between investigated groups were statistically significant (P lt 0,05). Conclusion is that sheep of body weight above 60kg have had significantly better reaction to the treatment.
AB  - Cilj ovog istraživanja je da se utvrdi da li postoje razlike u polnom reagovanju odraslih ovaca rase II d,frans u zavisnosti od telesne mase tretiranih plotkinja pri indukciji i sinhronizaciji estrusa pomoću fluorogeston acetata (FGA) i gonadotropnog hormona gravidnih kobila (SGŽK ili PMSG) u sezoni anestrije. Ukupno je tretirano 262 plotkinje, podeljene u tri grupe. UI grupu svrstane su ovce telesne mase 40-50 kg t.m., u II grupu 50-60 kg t.m. i u III grupu > od 60 kg t.m. (kontrolna grupa). Životinjama svih grupa intravaginalno su aplikovani sunđeri (30 mg fluorogeston acetata/sunđer) koji su ostali u vagini 12 dana. Na dan vađenja sunđera, ovcama je s.k., jednokratno aplikovan SGŽK u dozi od 500 i.j./grlo. Nakon dva dana izvršen je 'pripust iz ruke'. Dobijeni rezultati pokazuju da se iz I grupe ojagnjilo 43,78%; iz II 46,66% a iz III 59,32% tretiranih plotkinja. Prosečna plodnost ovaca po tretmanima I, II i III je iznosila 116,28% kod I grupe, 118,37% Il grupe, sto je ispod očekivanih vrednosti za rasu, dok je plodnost od 137,14% kod III grupe u granicama prosečnih vrednosti za rasu. Utvrđene razlike između ispitivanih grupa, u korist III grupe u odnosu na I i II grupu, bile su statistički značajne (P lt 0,05). Zaključak je da su ovce III grupe prosečne telesne mase od 67,68 kg, znatno bolje reagovale na primenjeni tretman jer je postignuta očekivana plodnost.

Each group received sponges of FGA. After removal of the sponges all sheep received intramuscular injection of 500 i.u of PMSG. The 'Sugonal' prepared by Veterinary institute Subotica was used. After two days the insemination was conducted. The results show that from first group 43.78% sheep lambed, from second group 46.66% and from third group 59.32%. Average sheep fertility after treatments was for the first group 113.28%, 118.37% for the second group and 137.14% for the third group. The ratio of singles, twins and triplets was for the first group 72:28:0 %, for the second group 70.69:24.14:5.17%, and for the third group 47.92:45.83:6.25%. Determined differences between number of lambed sheep and treated sheep, fertility and number of twins, as well as between investigated groups were statistically significant (P lt 0,05). Conclusion is that sheep of body weight above 60kg have had significantly better reaction to the treatment., Cilj ovog istraživanja je da se utvrdi da li postoje razlike u polnom reagovanju odraslih ovaca rase II d,frans u zavisnosti od telesne mase tretiranih plotkinja pri indukciji i sinhronizaciji estrusa pomoću fluorogeston acetata (FGA) i gonadotropnog hormona gravidnih kobila (SGŽK ili PMSG) u sezoni anestrije. Ukupno je tretirano 262 plotkinje, podeljene u tri grupe. UI grupu svrstane su ovce telesne mase 40-50 kg t.m., u II grupu 50-60 kg t.m. i u III grupu > od 60 kg t.m. (kontrolna grupa). Životinjama svih grupa intravaginalno su aplikovani sunđeri (30 mg fluorogeston acetata/sunđer) koji su ostali u vagini 12 dana. Na dan vađenja sunđera, ovcama je s.k., jednokratno aplikovan SGŽK u dozi od 500 i.j./grlo. Nakon dva dana izvršen je 'pripust iz ruke'. Dobijeni rezultati pokazuju da se iz I grupe ojagnjilo 43,78%; iz II 46,66% a iz III 59,32% tretiranih plotkinja. Prosečna plodnost ovaca po tretmanima I, II i III je iznosila 116,28% kod I grupe, 118,37% Il grupe, sto je ispod očekivanih vrednosti za rasu, dok je plodnost od 137,14% kod III grupe u granicama prosečnih vrednosti za rasu. Utvrđene razlike između ispitivanih grupa, u korist III grupe u odnosu na I i II grupu, bile su statistički značajne (P lt 0,05). Zaključak je da su ovce III grupe prosečne telesne mase od 67,68 kg, znatno bolje reagovale na primenjeni tretman jer je postignuta očekivana plodnost.",

AB  - Agriculture and food processing are most important branches of the economy in Republic of Serbia and account for 17% of gross domestic product (10.6% agricultural production and 6.4% food processing). In agriculture, 70% of production comes from plants and 30% from livestock. Annual consumption per capita in Serbia is 56 l milk and 38 kg meat products (18 kg of poultry, 16 kg of pork and 4 kg of beef). To obtain a more precise description of the dairy and beef sectors, as well as data for improving zoo-technical and farm conditions for ruminant production, a survey was conducted amongst farmers. A total of 1,180 questionnaires were mailed to farmers whose farms are registered for cattle, sheep, goat or mixed farming production. The questionnaire was divided into 6 sections: (1) general information about the farm; (2) technical and structural information; (3) education and advisory services; (4) perspectives for future activities; (5) sanitary and veterinary information; and (6) zoo-technical aspects. For more than 70% of farmers livestock production is the only source of income. One of the main structural problems which impede efficient development of ruminant production is the small scale of operation. A small property, with a small arable area results in a smaller number of animals being kept. About 37% of farmers have 10 or fewer cows on their farms, less than 20% of farmers have more than 20 sheep, and goat keeping is the least represented sector. Farmers and breeders associations are very fragmented and are not able to support their members in an effective way. About 75% of farmers expressed a positive expectation about future membership of Serbia in the EU, although these expectations are not clearly defined.

AB  - Well planned breeding program refers to achieving the advancement through selection of milking cattle. One of the most significant parameters of achieved results was the selection effect. The aim of this research was to show potential selection results which can be achieved in optimized breeding conditions for domestic population of milking cattle. Potential effects for the most important milk yield traits were estimated in standard lactation: milk yield, milk fat content and milk fat yield. Values of parameters that were used during the estimation were taken based on data from literature that engages in this type of research. Estimated selection effects in simulation I for milk yield, milk fat content and milk fat yield were 134,84 kg; 0,0258% i 4,95 kg. In second simulation estimated selection effect for same traits was: 217,55 kg; 0,029% i 7,87 kg. Results of conducted simulation point out at significant potential, meaning that in future period in order to put that potential to realization certain conditions have to be created by selective breeding work.

AB  - The objective of this research paper was to make an assessment of breeding value of performance tested gilts of Swedish Landrace and F-1 crossbreds of Swedish Landrace and Great Yorkshire by the method of selection index. The traits on whose basis the breeding value was estimated were: daily liveweight gain, average backfat thickness measured at two sites and carcass meat percentage. These traits were corrected for body mass of 100kg by the method of base indexes and the following average values were determined: corrected daily liveweight gain (KZDP) 408.93g/day, corrected average backfat thickness measured at two sites (KSL) 9.77mm and corrected carcass meat percentage (KPM) 61.08%. Studying the effect of genotype, year and birth season of gilts a statistically significant variation (P>0.05) of these traits provoked by the mentioned factors was not determined while the gilts sire statistically highly significantly (P lt 0.001) influenced all studied traits. Heritability coefficients were: h(2)= 0.255 for KZDP, h(2)= 0.356 for KSL and h(2)= 0.349 for KPM. The four selection index equations were constructed among which as the most optimal was chosen the one which includes all three traits (KZDP, KSL and KPM) and whose coefficient of the correlation of selection index and aggregate genotype was r(IAG) = 0.594.

AB  - In this paper results of age and different dosages of PMSG (500 and 750 i.u) on young II d’frans sheep fertility trait in anestric season are discussed. This research has clearly shown that first conception of young II d’frans sheep can be done at the age of 12-14 months as they reacted better at hormone dosages, compared to the group of sheep that was 11-13 months old. Higher dose of PMSG of 750i.u(for testing group) compared to 500i.u (control group) led to the result that test group had higher fertility rate by 30.66% compared to control group. Higher fertility of test group is represented by higher number of twins by 24.13% and triplets by 5.18% compared to control group.

AB  - In order to conduct selection on the larger number of traits, that are significant from the economic aspect, it is necessary to know the direction and strength of correlation between observed traits. In this research average values and variability of the most significant milk yield traits as well as coefficients of genetic and phenotype correlations are described. This research was conducted on 1369 cows that had finished their first three lactations in period from 2006 to 2010th year. Cattle were bread at 7 farms of Agricultural Corporation Belgrade and they are descendants of 29 bulls. The following traits were researched: milk yield, milk fat content and milk fat yield. Obtained genetic correlation values in this research were from -0.375 between milk fat content in entire lactation and milk yield in standard lactation, up to 0.998 for milk fat content in entire and standard lactation. Obtained phenotype correlation values were from -0.207 between milk yield in standard lactation and milk fat content in entire lactation up to 0.958 between milk yield and milk fat content in entire lactation.

AB  - Exceptionally important aspect in cattle production, from the aspect of production and economy, is ensuring normal and regular fertility. Every cattle breeder wants to have high-yielding animals which at the same time have good fertility. In proper cattle breeding this means that from each cow during single year one healthy calf is obtained. Use of artificial insemination has enabled that one breeding male is used as sire for several tens of thousands of progeny, however, there is always the risk that sires could be carriers of lethal and semi-lethal genes, which can cause huge losses of calves. In order to bring these undesirable occurrences to a minimum, so called bilogical test is included in the breeding and selection activities, i.e. bulls are tested through their progeny for presence of difficult calving (dystocia) abd calf losses caused by genetic anomalies. In Republic of Serbia, this test is carried out on ehtire Simmental population in an exchange of data produced by primary breeding organizations. Per each tested bull, it is necessary to have data on minimum 50 randomly selected calves. Calves are examined visually 65 days after the birth, at the latest. In the present study, the results of the biological testing of 35 Simmental bulls, sires of total 3572 calves on the territory of Central Serbia, in the period 2008-2009, are used. The effect of sires on parameters of biological test were studied: body mass of calves at birth, calf score and calving score. Also, bulls were ranked based on said parameters, male/female calves ratio and percentage of twins and still-born calves for each bull individually were determined. After the rank of bulls was established, the correlation between the rank and studied fertility traits was determined. Correlations were expressed using the Spearman coefficient. Research results show that the effect of bulls was very high p lt 0,001 on all three parameters of the biological test, and also that the percentage of still born calves for all bulls was within limits, with the exception of bulls Zahlo (HB 1497) and Woz (HB 1433) where it was above 5.
AB  - Izuzetno važan aspekt u govedarskoj proizvodnji, gledano sa proizvodnog i ekonomskog stanovišta je obezbeđivanje normalne i redovne plodnosti. Svaki odgajivač goveda želi da ima grla koja su visoko proizvodna i istovremeno poseduju dobru plodnost. Za pravilno odgajivanje goveda to znači da se od svake krave u toku godine dobije po jedno zdravo tele. Upotreba veštačkog osemenjavanja omogućila je da jedan priplodnjak bude otac nekoliko desetina hiljada potomaka. Međutim, uvek postoji rizik da su očevi nosioci letalnih i semiletalnih gena, što može prouzrokovati velike gubitke teladi. Da bi se ove nepoželjne pojave svele na najmanju moguću meru u odgajivački i selekcijski rad uključeno je ispitivanje bikova po potomstvu na teška teljenja i gubitke teladi izazvane genetskim anomalijama, tzv. biološki test. Ovaj test se u Republici Srbiji vrši jedinstveno za čitavu populaciju simentalske rase, razmenom podataka između odgajivačkih organizacija. Po svakom biku koji se testira, neophodno je imati podatke za najmanje 50 slučajno odabrane teladi. Vizualni pregled teladi se obavlja najkasnije do 65 dana, od datuma rođenja teleta. U ovom istraživanju korišćeni su rezultati biološkog testa 35 bikova simentalske rase koji su bili očevi ukupno 3572 teladi na teritoriji centralne Srbije u periodu 2008. i 2009. godine. U radu je ispitivan uticaj očeva na parametre biološkog testa: telesnu masu teladi po rođenju, ocenu teleta i ocenu toka teljenja. Takođe je izvršeno rangiranje bikova na ove parametre, kao i utvrđivanje odnosa muške i ženske teladi, procenat bližnjenja kao i procenat mrtvorođene teladi za svakog bika posebno. Nakon utvrđenog ranga bikova izvršena je korelacija ranga ispitivanih osobina plodnosti. Korelacije su iskazane Spirmanovim koeficijentom. Rezultati istraživanja pokazali su da je uticaj bikova izuzetno visok p lt 0,001 na sva tri parametra u biološkom testu, kao i da je procenat mrtvorođene teladi kod svih bikova u dozvoljenim granica, osim bikova Zahlo (HB 1497) i Woz (HB 1433) gde je iznosio preko 5.

AB  - In order to have a more precise description of dairy farm structure and characteristics of dairy production systems, as well as to assess possibilities for improving production and farming conditions in which milk production is organized, a survey based research was directed at a select group of farms across the Serbia. 1180 questionnaires have been mailed to farmers whose farms are registered for either cattle or mixed production. Questionnaire was divided into 6 sections: general information of the farm, agricultural and structural information, zootechnical information, sanitary and veterinarian information, information about education and extension, and information on the perspectives of future farming. About 59% of analyzed farms have size up to 20 ha, with average size of about 10 ha. On the other hand, about 55% farms raises up to 15 cows and heifers with average of 6 heads per farm, while 3% of farms have more than 200 cows and heifers. Over 86% of surveyed farmers intend to expand existing farm production, mainly by increasing the number of animals, stricter selection and improvement of the conditions for feeding, housing, care and milking. About 75% of farmers have expressed a positive expectation from future membership of Serbia in EU, although these expectations are not clearly defined.

Values of phenotype variability as well as coefficient of heritability and correlations between milk yield traits analyzed in this research are shown in this paper. The paper includes 1109 first standard lactations of black and white breed cows, offspring of 9 fathers bred at 7 farms of Agricultural Corporation Belgrade during the year 2008. The paternal influence was researched as well as breeding farm, calving season influence to phenotype expression and variations of milk yield traits in standard lactation. Statistically very significant (p lt 0,01) influence of the bull, farm and calving season on phenotype expressiveness, variability of milk yield, milk fat yield and protein yield in standard lactation was determined. Determined values of heritability for milk yield traits, milk fat contents, protein contents in milk, milk fat yield and milk protein yield were: 0.115, 0.049, 0.017, 0.119. and 0.111, retrospectively. Genetic correlations coefficient values of milk yield traits were from: -0.746 (milk fat yield - protein content) to 0.983 (milk fat yield-protein yield).

AB  - It is of economic interest for breeders that dairy cattle should be long enough in production, without compromising their health or reproductive performance. In modern dairy cattle breeding programs, in addition to traits of which dairy production directly depends on, emphasis is also placed on those traits that contribute to improving production efficiency, primarily by reducing production cost. These traits are known as functional traits, among which is longevity of cows one of the most important. Longevity indicates the time period during which the cow remains in the herd before being culled. The aim of this paper is to present the most important characteristics of longevity of cows as a very important functional traits of dairy cattle.

AB  - In this paper, the effect of different systems of crossing of sheep: two-breed (PxW) and three-breed (PxWxIDF) on production results - body weight and average daily gain of lambs weaned at the age of 60 days and fattened to age of 120 days, was investigated. Also, the effect of crossing on consumption and conversion of food and nutrients was monitored. Study was carried out on the Experimental sheep farm of the Institute for Animal Husbandry, Belgrade-Zemun, and following breeds were used in the crossing: Pirot Pramenka (P), Wurttemberg (W) and Ile de France (IDF). Pirot Pramenka was used as the maternal basis, while Wurttemberg rams were used as sires, and as terminal breed, Ile de France rams were used. Results have shown that the three-breed crosses of F1 generation, compared to two-breed crosses, obtained higher body gain for 19.23% with lower food intake for 5.19%, during fattening period lasting from 60th to 120th day of age. Regarding feed conversion ratio, they used per 1 kg of body gain 29.61% less hay and 20.82% less concentrate feeds. Positive biological effect exhibited in three-breed crosses (PxWxIDF) is consequence of individual heterosis and maternal heterosis.

Istraživanja su obavljena na eksperimentalnoj farmi ovaca Instituta za stočarstvo Beograd-Zemun, a za ukrštanje su korišćene sledeće rase ovaca: pirotska pramenka (P), virtemberg (W) i Il de frans (IDF). Rezultati su pokazali da su trorasni melezi u odnosu na dvorasne, u tovu od 60. do 120. dana uzrasta ostvarili za 19.23% veći prirast i za 5.19% manje konzumiranje hrane. U pogledu konverzije hrane, po kg prirasta su utrošili za 29.61% manje sena i za 20.82% manje koncentrata. Pozitivan biološki efekat koji se ispoljio kod meleza (PxWxIDF) je posledica korišćenja heterozisa individue i heterozisa majke.

AB  - Grasslands represent significant natural resource with important role in economy and ecology of every country. Properly cultivated and utilized grasslands provide cheap and high quality food for sheep, which they easily transfer into milk and meat. However, extensive management has caused degradation of pasture areas. Improvement of production of forage plants on pastures is achieved by using melioration measures, primarily fertilization. Fertilization is important also from the aspect of increase of yield and quality of forage plants. The effect of application of fertilizer depends on the present plant species in the mixture. Application of nitrogen mineral fertilizers in mixtures reduces the nitrogen fixating abilities of leguminous species, which leads to the diminishing of their competitive abilities and favouring of the grass component in the mixture. Use of excessive quantities of N fertilizer in plants causes the accumulation of nitrates, as a unfavourable quality parameter in plant tissues, which can have harmful effect on animal health. Therefore, attention should be focused on application of N fertilizers, which should be harmonized with the plant requirements, so that used quantities are not excessive and harmful. Objective of this paper is to point out the significance of fertilization as one of the most important melioration measures.
AB  - Travnjaci su značajan prirodni resurs koji ima važnu ulogu u ekonomiji i ekologiji svake zemlje.Pravilno negovani i iskorištavani ,travnjaci obezbeđuju jeftinu i kvalitetnu hranu za ishranu ovaca koju one uspešno transformišu u mleko i meso. Međutim, ekstenzivno gazdovanje je uslovilo degradaciju pašnjačkih površina.Unapređenje proizvodnje krme na pašnjacima se postiže primenom meliorativnih mera, u prvom redu đubrenja. Đubrenje ima značajan uticaj na povećanje prinosa i kvaliteta krme. Efekat primene đubriva zavisi od prisutne biljne vrste u smeši. Primena azotnih mineralnih đubriva u smešama, smanjuje azotofiksatorne sposobnosti leguminoznih vrsta, što dovodi do slabljenja njihovih konkurentnih sposobnosti i favorizovanja travne komponente u smeši.

abstract = "Grasslands represent significant natural resource with important role in economy and ecology of every country. Properly cultivated and utilized grasslands provide cheap and high quality food for sheep, which they easily transfer into milk and meat. However, extensive management has caused degradation of pasture areas. Improvement of production of forage plants on pastures is achieved by using melioration measures, primarily fertilization. Fertilization is important also from the aspect of increase of yield and quality of forage plants. The effect of application of fertilizer depends on the present plant species in the mixture. Application of nitrogen mineral fertilizers in mixtures reduces the nitrogen fixating abilities of leguminous species, which leads to the diminishing of their competitive abilities and favouring of the grass component in the mixture. Use of excessive quantities of N fertilizer in plants causes the accumulation of nitrates, as a unfavourable quality parameter in plant tissues, which can have harmful effect on animal health. Therefore, attention should be focused on application of N fertilizers, which should be harmonized with the plant requirements, so that used quantities are not excessive and harmful. Objective of this paper is to point out the significance of fertilization as one of the most important melioration measures., Travnjaci su značajan prirodni resurs koji ima važnu ulogu u ekonomiji i ekologiji svake zemlje.Pravilno negovani i iskorištavani ,travnjaci obezbeđuju jeftinu i kvalitetnu hranu za ishranu ovaca koju one uspešno transformišu u mleko i meso. Međutim, ekstenzivno gazdovanje je uslovilo degradaciju pašnjačkih površina.Unapređenje proizvodnje krme na pašnjacima se postiže primenom meliorativnih mera, u prvom redu đubrenja. Đubrenje ima značajan uticaj na povećanje prinosa i kvaliteta krme. Efekat primene đubriva zavisi od prisutne biljne vrste u smeši. Primena azotnih mineralnih đubriva u smešama, smanjuje azotofiksatorne sposobnosti leguminoznih vrsta, što dovodi do slabljenja njihovih konkurentnih sposobnosti i favorizovanja travne komponente u smeši. Upotreba prevelikih količina N đubriva kod biljaka izaziva nagomilavanje nitrata, kao nepoželjnog parametra kvaliteta u biljnim tkivima, koji mogu da imaju štetno dejstvo na zdravstveno stanje životinja. Iz tih razloga treba pokloniti veliku pažnju primeni N đubriva, koja treba da bude u skladu sa potrebama biljaka, kako upotrebljene količine ne bi bile prevelike i štetne. Cilj ovog rada je bio da ukaže na značaj đubrenja kao jedne od najvažnijih meliorativnih mera.",
