AB  - The purpose of this review is to review the current state and achievements in poultry production in Serbia and worldwide, primarily the EU. Particular emphasis is placed on impacts of different rearing system, i.e. housing and fattening, on the production and the quality of the poultry meat and eggs and, simultaneously, on the welfare of poultry and environmental protection according to EU standards. According to the latest available data, total number of poultry produced in Serbia in 2015 was 17,450,000 units and production of meat amounted to around 86,000 t, while consumption was 12.12 kg per person. Egg production in 2015 was approximately 1.7 billion eggs, which is around 202 eggs per hen. A total of 13.1 million tons of poultry meat was produced in EU in 2015. It is evident from the literature that the poultry production in EU and worldwide has undergone significant changes, and clear criteria have been established to improve the quality of the products (meat and eggs), to guarantee the safety of the food, to protect the environment, and to ensure animal welfare in line with the relevant ethic norms. For these reasons, many countries within EU and worldwide, including Serbia, attach importance to housing systems for laying hens, with particular concern for animal welfare. Alternative housing systems (floor, aviary, free range and organic production) are increasingly used in the production of poultry meat and eggs instead of conventional systems. This is because it is considered that alternative housing systems may have positive effect on the productive traits of the poultry and, consequently, on the production of the quality organic meat. Furthermore, it is evident from research that pure (indigenous) breeds and strains are given growing importance in the production of organic meat and eggs in semi-intensive, semi-extensive and even in extensive rearing systems.

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.

U 42. nedelji starosti (sredina proizvodnog ciklusa) telesna težina nosilja iznosila je 3565,10 g (Ross 308) i 3599,05 g (Cobb 500), dok je na kraju proizvodnog ciklusa (61. nedelja starosti) telesna težina nosilja hibrida Ross 308 iznosila 3841,50 g, a Cobb 500 3850,00 g. Utvrđene razlike telesne težine nosilja (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 reproduktivne performanse brojlerskih roditelja utvrđeno je izračunavanjem koeficijenata fenotipske korelacije između ispitivanih pokazatelja.

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.

AB  - The use of selenium as animal feed supplement in Serbia was approved in 1989 for some categories of pigs, sheep and poultry. From 2000 selenium in animal feed became a requirement for all categories of farm animals. The aim of this study was to determine the consumption of selenium by Serbian livestock and in poultry production between 1990-1991 and 2000-2008 and to analyze the selenium content of meat, milk and eggs sold on Serbian markets to gain insight into human selenium intake. Data indicate a low level of selenium inclusion in animal feed during 1990-1991 compared to during 2000-2008. These results coincide with Serbian regulations. From 2001 an organic form of selenium (selenized yeast) was introduced in small quantities (less than 8% of the total consumed selenium). Analysis of meat, milk and eggs from Serbian markets shows increased selenium levels compared to 1991. However, the estimated total human daily intake in Serbia is 40.9 μg, which is under the recommended quantity. Increasing the quantity of selenium included in animal feed and the substitution of inorganic selenium with selenized yeast could be beneficial for animal health and farm productivity. As a consequence a further improvement in the human selenium status in Serbia should be possible.

Od 2000. propisan je obavezan sadržaj selena u hrani za sve domaće životinje. Cilj rada bio je istraživanje upotrebe selena za suplementaciju stočne hrane selenom u periodima 1990-1991 i 2000-2008 i analiza sadržaja selena u namirnicama životinjskog porekla. Rezultati ukazuju na povećanu upotrebu selena kao aditiva za stočnu hranu od 2000. i povećan sadržaj selena u svinjskom mesu i jajima u poređenju sa podacima iz 1991. Procenjeni dnevni unos selena stanovnika Srbije je 40.9 μg što je značajno manje od preporučenog dnevnog unosa selena. Povećana upotreba selena u ishrani domaćih životinja, i zamena neorganskih jedinjenja selena seleniziranim kvascem, pored povoljnih efekata na zdravlje i produktivnost životinja, dovela bi do daljeg poboljšanja statusa selena stanovnika Srbije.

AB  - A 42-day experiment was conducted to compare the effects of various levels of sodium selenite (SS) and Se-enriched yeast (SY) on chicken productivity, carcass traits, and breast Se concentration. Six hundred 1-day-old Cobb 500 broiler chicks were placed on 1 of 6 experimental treatments. The treatments consisted of feeding a diet without Se supplementation (basal diet) or basal diet with 0.6 mg/kg supplemented Se supplied by SS, SY, or a mix of the two (0.45 SS + 0.15 SY; 0.3 SS + 0.3 SY; 0.15 SS + 0.45 SY). Chicks in all Se-supplemented treatments had significantly higher final body weight and eviscerated weight than those on the basal diet (P  lt  0,05) and no significant differences were observed among selenium source (P  lt  0.05). Also, chicks in all Se-supplemented treatments had significantly higher Se contents in breast tissue than the control group (P  lt  0.05). Replacing SS by SY in the broiler diets resulted in increased concentrations of Se in the breast (P  lt  0.01). Strong correlations were found between breast Se concentrations and the level of SY supplementation of the broiler diet (r = 0.992). The results from this experiment indicate that SY is a superior source of selenium for the production of selenized meat, and can be used, without any detrimental effect on chicken performance, for adding nutritional value to broiler meat and thus safely improving human selenium intake.

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.
