AB  - Ishrana brojlera je jedan od najznačajnijih uslova za ispoljavnje genetskog potencijala savremenih hibrida, a u ukupnim troškovima proizvodnje čini oko 70 %. U proizvodnim uslovima, kod nas i u svetu, najčešće primenjivan koncept ishrane brojlera je sa tri do pet potpunih krmnih smeša. NCR 1994 (National Research Council, USA) za ishranu brojlera definiše potrebe za tri fiksna perioda: starter (1-3 nedelje), grover (3-6 nedelja) i finišer (6-8 nedelja). Rezultati istraživanja ukazuju da pri ishrani sa tri ili četiri smeše, potrebe brojlera u pojedinim fazama tova nisu usaglašene sa nutritivnim sastavom smeša. Posledice pothranjenosti/prehranjenosti brojlera istovremeno predstavljaju ekonomski i ekološki problem u proizvodnji pilećeg mesa. Nedostatak proteina u starter periodu rezultira izostankom osnove za optimalan rast, dok višak proteina u finišer periodu dovodi, sa jedne strane do povećanja troškova proizvodnje usled ishrane smešama višeg nivoa proteina, koje imaju višu cenu, pri čemu za njima nema realne potrebe, a sa druge strane, do ekološkog problema usled povećanja ekskrecije azota u fecesu, koji potiče iz viška proteina u hrani. U rešavanju problema neprecizne ishrane primenjuju se različiti programi multifazne ishrane, pri čemu su jedni sa fokusom na ekonomičnost, pojedini na očuvanju životne sredine, dok pojedini programi imaju za cilj jedno i drugo i zasnivaju se na konceptu sniženog sadržaja proteina do nivoa kojim se ne ugrožavaju proizvodne performanse brojlera, a ostvaruje se smanjenje ekskrecije azota.
Inovacija novog modela multifazne ishrane brojlera zasniva se na definisanom programu ishrane za provenijencu Ross 308, za tov pilića po polovima, sa ukupno devet smeša, uključujući i tehnološki postupak njihovog dobijanja.

AB  - This study evaluates the effect of protease-supplemented diets containing different crude protein levels, sex and length of the fattening period on the weight and percentage yield of primal cuts in Cobb 500 broilers. Chickens were fed maize-and-soybean-based diets. Fattening periods lasted 49 and 63 days. The results showed that the recommended crude protein reduction by 4% in diets
supplemented with 0.2% protease had no effect on the weight and percentage yield of primal cuts (P>0.05), while the effect of broiler sex and slaughter age on the studied carcass quality parameters was significant (P<0.05).

AB  - The aim of this study was to evaluate the effect of rearing system, genotype and hens age on egg weight and eggs components share. The tested rearing systems were the floor and organic, and tested genotypes were Isa Brown hybrid and New Hampshire breed. Eggs were collected for analyses three times in production cycle (32 weeks hens age, 48 weeks hens age, and 72 weeks hens age). In these samples (fifteen eggs per group, eggs were one day old) were investigated: egg weight, albumen share, yolk share and shell share. Egg weight was increased with hens age. Also, the interaction between the genotype and hens age was found, so the New Hampshire eggs in 32 weeks had less weight then Isa Brown eggs (p≤0.05), while in the 48 and 72 weeks this difference was lost (p≥0.05). The share of egg albumen and yolk was significantly affected by the rearing system, genotype and hens age (p≤0.05). Floor produced eggs had a lower proportion of albumen and a higher proportion of yolk compared to organic eggs. New Hampshire eggs had a higher content of yolk and the smaller content of albumen compared to Isa Brown eggs (p≤0.05). With hens age, the share of yolk was increased and albumen share was decreased. Interaction of all three studied factors - rearing system x genotype x hens age had the most important effect on the shell share.
AB  - Cilj ovog rada je bio da ispita uticaj sistema gajenja, genotipa i starosti kokoši nosilja na masu i udeo glavnih delova jaja. Ispitivani sistemi gajenja su bili podni i organski, a ispitivani genotipovi Isa Brown hibrid i New Hampshire rasa. Jaja su sakupljana za analizu tri puta za vreme proizvodnog ciklusa (kod 32-nedeljnih nosilja, 48-nedeljnih i 72-nedeljnih). Na ovim uzorcima (15 jaja po grupi, jaja stara jedan dan) su ispitivani: masa jaja, udeo belanca, udeo žumanca i udeo ljuske jaja. Masa jaja se povećavala sa starenjem nosilja. Takođe, interakcija genotip x starost nosilja je bila značajna, pa su New hampshire kokoši u 32. nedelji nosile jaja manje mase od Isa Brown hibrida (p≤0.05), dok tih razlika u 48. i 72. nedelji nije bilo (p≥0.05). Udeo belanca i žumanca je bio od značajnim uticajem sistema gajenja, genotipa i starosti nosilja (p≤0.05). Podno gajenje kokoši su nosile jaja koja su imala manji udeo belanca a veći udeo žumanca u poređenju sa organskim kokošima (p≥0.05). Jaja New Hampshire rase su imala manji udeo belanca a veći udeo žumanca u poređenju sa Isa Brown genotipom (p≥0.05). Sa starenjem kokoši, udeo žumanca se povećavao a udeo belanca smanjivao. Interakcija sva tri ispitivana faktora - sistema gajenja, genotipa i starosti nosilja je imala najznačajniji uticaj na udeo ljuske jaja.

AB  - The aim of this paper was to estimate the effect of rearing systems (floor and organic) on the chemical composition of meat of laying hens. The tested genotypes were Isa Brown hybrid and dual purpose breed New Hampshire. Based on the results of this research can be concluded that the rearing system, generally, did not caused statistically significant differences in any of the parameters examined chemical composition of meat. On the other hand, the breast meat - white meat and thigh and drumstick - dark meat of New Hampshire genotype had significantly higher fat content compared to the Isa Brown hybrid. It must be noted that in the breast meat reported significant interaction genotype x rearing system. The other parameters of the chemical composition of meat were not significantly different between reared genotypes.

AB  - This study evaluates the effect of different crude protein levels in broiler diets supplemented with 0.2% and 0.3% protease enzyme (Ronozyme Pro Act) on dressed carcass weight and dressing percentage during two fattening periods (49 and 63 days). The fast-growing strain Cobb 500 was used. At the end of the fattening trial i.e. at 49 and 63 days, 10 male and 10 female birds were randomly sacrificed from each experimental group to determine body weights and conventionally dressed, ready-to-roast and ready-to-grill carcass weights. The data obtained were used to calculate the dressing percentages of the differently dressed carcasses. Results indicated that carcass weights and dressing percentages were not affected by diet (P>0.05), but also showed that the increase in the length of the fattening period by two weeks (from 7 to 9 weeks) led to increased carcass weights, while dressing percentages decreased (P (lt) 0.05).
AB  - U radu su prikazani efekti različitih nivoa sirovih proteina u hrani za tovne piliće, uz dodatak enzima proteaze (Ronozyme Pro Act) u količini 0,2% i 0,3% na masu i randmane obrađenih trupova pri različitom trajanju tova (49 i 63 dana). U ogledu je korišćen brzorastući tovni hibrid Cobb 500.

abstract = "This study evaluates the effect of different crude protein levels in broiler diets supplemented with 0.2% and 0.3% protease enzyme (Ronozyme Pro Act) on dressed carcass weight and dressing percentage during two fattening periods (49 and 63 days). The fast-growing strain Cobb 500 was used. At the end of the fattening trial i.e. at 49 and 63 days, 10 male and 10 female birds were randomly sacrificed from each experimental group to determine body weights and conventionally dressed, ready-to-roast and ready-to-grill carcass weights. The data obtained were used to calculate the dressing percentages of the differently dressed carcasses. Results indicated that carcass weights and dressing percentages were not affected by diet (P>0.05), but also showed that the increase in the length of the fattening period by two weeks (from 7 to 9 weeks) led to increased carcass weights, while dressing percentages decreased (P (lt) 0.05)., U radu su prikazani efekti različitih nivoa sirovih proteina u hrani za tovne piliće, uz dodatak enzima proteaze (Ronozyme Pro Act) u količini 0,2% i 0,3% na masu i randmane obrađenih trupova pri različitom trajanju tova (49 i 63 dana).

AB  - Egg producers in the EU had more than a decade to adapt to Directive 1999/74/EC which prohibits keeping laying hens in battery cages after 2012. Meanwhile, numerous studies have been conducted in order to assess the socio-economic implications of this ban and to evaluate consumers' willingness to support improvement in layer welfare by paying a higher price for eggs produced in alternative systems. The adoption of such regulations in Serbia with the implementation timeframe of less than two years, and without any assessment of consumers' willingness to pay a higher price for eggs from alternative systems, places the burden of animal welfare on producers. Considering the overall difficult financial situation of egg producers, this poses a risk that a large number of egg producers in Serbia will leave the sector after 2012.

AB  - The aim of this work was to evaluate production traits, egg quality parameters and welfare indicators of two strains of layers (Hisex White and Hy Line Brown) kept in different housing systems. In each housing system both strains of layers were housed and that made 6 treatments in 2 x 3 factorial design (2 genotypes x 3 cage types). A) conventional battery-cages with 5 hens per cage providing 500 cm(2) of floor space per bird (n = 180 (90 white and 90 brown layers), 36 cages in total, 5 hens/cage, floor space = 500 cm(2)/hen); 13) enlarged battery-cages with 5 hens per cage providing 650 cm(2) of floor space per bird (n = 120 (60 white and 60 brown layers), 24 cages in total, 5 hens/cage, floor space = 650 cm(2)/hen); C) enriched cages with 60 hens per compartment providing 750 cm(2) of floor space per bird (n = 360 (180 white and 180 brown layers), 6 cages in total, 60 hens/cage, floor space = 750 cm(2)/hen). Examination of egg quality parameters was carried out in 8 lour-week periods, starting from 32 weeks of rage on the random sample of 30 eegs per treatment. Condition of feathers ware evaluated by scoring system at the end of the production cycle (70 weeks of age), and at the same time duration of tonic immobility was measured. The results showed that white layers in conventional cages achieved the best production results. The highest number of eges was achieved with white layers in B and the lowest with the brown layers in C. White layers laid considerably more eggs compared to brown layers and had the best shell quality in all of the three housing systems. The birds in enriched cages laid significantly less eggs compared to other two cage types. The worst feather condition at the end of the production cycle was noticed in conventional cages (A) in both hybrids. Generally, brown layers suffered from more severe feather damage in all cage types compared to the white layers. The results showed a significant effect of cage type (p (lt) 0.01) and hybrid type (p (lt) 0.05) on duration of tonic immobility (TI) indicating that fearfulness of the birds was highly affected by, housing system and genotype. Birds from both genotypes kept in conventional cages showed a shorter duration of TI than the birds kept in enriched cages and the white layers showed longer duration of TI than the brown layers.

AB  - In broiler production, stocking density, i.e. floor surface per chicken, is very important welfare factor which directly and indirectly influences and determines the level of growth of chicken body weight, but it is also related to other welfare indicators. Objective of the paper was to define the broiler welfare in different stocking densities by evaluation of their walking ability (gait score), feathering, incidence and degree of hock burns, foot pad lesions, and by determination of the biochemical blood parameters (glucose concentration, total cholesterol concentration), as indicators of condition of stress. One day old chickens of Hubbard genotype were housed in boxes in floor rearing system, in 3 stocking densities and 5 repetitions of each treatment. Treatment A scored stocking density of 10 birds/m2; treatment B, 13 birds/m2 and treatment C, 16 birds/m2. Results of the trial indicate absence of significance of differences between trial groups of broilers in regard to their walking ability, condition of skin and legs, and stress indicators. In general, broiler welfare in all trial groups was satisfactory. However, determined tendencies of worsening of the condition of litter, increase of the frequency of lower scores for walking ability (gait score), hock burns and foot pad lesions which occur with increase of stocking density, indicate the importance of this rearing factor and need to define limiting stocking densities from the aspect of broiler welfare but also economical efficiency of production.
AB  - U brojlerskoj proizvodnji gustina naseljenosti, odnosno površina poda po piletu, je veoma važan faktor dobrobiti koji svojim direktnim i indirektnim uticajima određuje nivo porasta telesne mase pilića ali se dovodi u vezu i sa drugim indikatorima dobrobiti. Cilj rada je bio definisanje dobrobiti brojlera u različitim gustinama naseljenosti ocenom sposobnosti kretanja (gait score), operjalosti, pojave i stepena zapaljenja kože zgloba, lezije na jastučiću stopala i utvrđivanjem biohemijskih parametara krvi (koncentracija glukoze, koncentracija ukupnog holesterola) kao pokazatelja stanja stresa. Jednodnevni pilići genotipa Hubbard su razmešteni u bokseve podnog sistema gajenja u 3 gustine naseljenosti i 5 ponavljanja svakog tretmana. Tretman A je označavao gustinu naseljenosti 10 grla/m2; tretman B, 13 grla/m2 i tretman C, 16 grla/m2. Rezultati ogleda ukazuju na nesignifikantnost razlika oglednih grupa brojlera u pogledu sposobnosti kretanja, stanja kože i nogu, indikatora stresa. Generalno, dobrobit brojlera u svim oglednim grupama je bila zadovoljavajuća. Međutim, utvrđene tendencije pogoršanja kvaliteta prostirke, povećanja frekvencije lošijih ocena sposobnosti kretanja (gait score), zapaljenja kože zgloba i lezije na jastučiću stopala sa povećanjem gustine naseljenosti, ukazuju na značaj ovog faktora gajenja i potrebu definisanja limitirajućih gustina naseljenosti sa aspekta dobrobiti brojlera ali i ekonomičnosti proizvodnje.

AB  - Research was carried out on chickens of four genotypes: two slow-growing genotypes, Master Gris (MG) and Farm Q (FQ), one fastgrowing, Hubbard Classic (HC) and one medium-growing Red Bro (RB). To the age of 3 weeks, chickens were reared according to all technological norms for intensive production. After that period, chickens were moved and fattening in extensive conditions resumed, using unlimited free range. The significance of genotype on body mass was established. The greatest final body mass was established in chickens of the Master Gris genotype (1983 g) and the lowest in Farm Q (1371 g). Fast-growing chickens of genotype Hubbard Classic at the age of 84 days had body mass at the level of medium-growing Red Bro genotype at the age of 91 days (1730 g, and 1759 g, respectively). In accordance to the established body mass, slaughter yields of Farm Q broilers were significantly the lowest. Also, chickens of this genotype also had significantly (p (lt) 0.05) lower share of abdominal fat compared to other genotypes. Chickens of Master Gris and Red Bro genotypes had significantly greater shank length (22.57 and 21.01 g/mm, respectively), whereas in fast-growing genotype Hubbard Classic a significantly greater breast angle (90.15 degrees) was determined. Accordingly, share of breast (15.90 %), as well as share of breast meat (10.11 %) was significantly greater in carcasses of Hubbard Classic chickens.
AB  - Ovo ispitivanje je obavljeno na pilićima četiri genotipa: dva sporog porasta, Master Gris (MG) i Farm Q (FQ), jednog brzog porasta, Hubbard Classic (HC) i jednog 'medium-growing' Red Bro (RB). Pilići su do uzrasta 3 nedelje gajeni po svim tehnološkim normativima intenzivne proizvodnje. Nakon tog perioda, izvršeno je preseljenje pilića i nastavljen je tov u ekstenzivnim uslovima, sa korišćenjem neograničenog ispusta. Utvrđen je signifikantan uticaj genotipa na telesnu masu. Najveću završnu telesnu masu su postigli pilići genotipa Master Gris (1983 g) a najmanju Farm Q (1371 g). Brzo-rastući brojleri genotipa Hubbard Classic su u uzrastu od 84 dana imali telesnu masu u nivou 'medium-growing' genotipa Red Bro u uzrastu od 91 dana (1730 g, odnosno 1759 g). U skladu sa utvrđenom telesnom masom, i klanični randmani pilića Farm Q su bili signifikantno najmanji. Takođe, pilići ovog genotipa su imali i značajno (p (lt) 0,05) manji udeo abdominalne masti u odnosu na ostale genotipove. Pilići genotipa Master Gris i Red Bro su imali značajno veću dužinu piska (22,57 i 21,01 g/mm), dok je kod brzorastućeg genotipa Hubbard Classic utvrđen signifikantno veći grudni ugao (90,15 stepeni). Saglasno tome i udeo grudi (15,90 %), kao i udeo mesa grudi (10,11 %) je bio signifikantno veći u trupu pilića Hubbard Classic.

In accordance to the established body mass, slaughter yields of Farm Q broilers were significantly the lowest. Also, chickens of this genotype also had significantly (p (lt) 0.05) lower share of abdominal fat compared to other genotypes. Chickens of Master Gris and Red Bro genotypes had significantly greater shank length (22.57 and 21.01 g/mm, respectively), whereas in fast-growing genotype Hubbard Classic a significantly greater breast angle (90.15 degrees) was determined. Accordingly, share of breast (15.90 %), as well as share of breast meat (10.11 %) was significantly greater in carcasses of Hubbard Classic chickens., Ovo ispitivanje je obavljeno na pilićima četiri genotipa: dva sporog porasta, Master Gris (MG) i Farm Q (FQ), jednog brzog porasta, Hubbard Classic (HC) i jednog 'medium-growing' Red Bro (RB). Pilići su do uzrasta 3 nedelje gajeni po svim tehnološkim normativima intenzivne proizvodnje. Nakon tog perioda, izvršeno je preseljenje pilića i nastavljen je tov u ekstenzivnim uslovima, sa korišćenjem neograničenog ispusta. Utvrđen je signifikantan uticaj genotipa na telesnu masu. Najveću završnu telesnu masu su postigli pilići genotipa Master Gris (1983 g) a najmanju Farm Q (1371 g). Brzo-rastući brojleri genotipa Hubbard Classic su u uzrastu od 84 dana imali telesnu masu u nivou 'medium-growing' genotipa Red Bro u uzrastu od 91 dana (1730 g, odnosno 1759 g). U skladu sa utvrđenom telesnom masom, i klanični randmani pilića Farm Q su bili signifikantno najmanji. Takođe, pilići ovog genotipa su imali i značajno (p (lt) 0,05) manji udeo abdominalne masti u odnosu na ostale genotipove. Pilići genotipa Master Gris i Red Bro su imali značajno veću dužinu piska (22,57 i 21,01 g/mm), dok je kod brzorastućeg genotipa Hubbard Classic utvrđen signifikantno veći grudni ugao (90,15 stepeni). Saglasno tome i udeo grudi (15,90 %), kao i udeo mesa grudi (10,11 %) je bio signifikantno veći u trupu pilića Hubbard Classic.",

AB  - Subsequent to banning of use of antibiotics as growth promoter sin poultry nutrition, numerous studies turned to finding of alternative solutions, i.e. other, natural substances, which would have positive effect on chicken growth and feed conversion. Today, several groups of these additives are in use, and most often probiotics, prebiotics, enzymes, acidifiers, antioxidants and phytogene additives. Considering that each of the stated groups has its own specificities, objective of this work was to present main mechanism of their action and to present their effect on production results in fattening of broiler chickens through review of research published in this field.
AB  - Nakon zabrane upotrebe antibiotika kao promotera porasta u ishrani živine, veliki broj istraživanja okrenut je upravo iznalaženju alternativnih rešenja, odnosno nekih drugih, prirodnih supstanci koje će imati pozitivan efekat na prirast pilića i konverziju hrane. Danas je u upotrebi više grupa ovih aditiva, a najčešće se koriste probiotici, prebiotici, enzimi, zakišeljivači, antioksidanti i fitogeni aditivi.

AB  - One of the by-products of corn processing which can successfully be used in poultry nutrition is livestock meal. In this trial corn meal was investigated, meal in two form: non-extruded (T1 and T2) and extruded (T3 and T4) as a replacement of cracked corn (K) in the amount of 100% (T1 and T3) and 50% (T2 and T4). Investigation was carried out in 4 repetitions, 75 chickens of Arbor Acres x Ross 308 hybrid in each group. Trial lasted 42 days. Chickens were fed three standard mixtures (starter, grower and finisher). Investigation demonstrated that group of chickens of treatment T3 realized the best final body masses (2254g), followed by chickens in treatment T4 (2173g), chickens of group T2 (2112g), K group (2106 g), and the worst results were established in chickens of group T1 (2103g). It was established that differences in final body mass of chickens from group T3 in relation to chickens from groups T1, T2, T4 and were statistically highly significant (P (lt) 0,001). Statistically significant differences (P (lt) 0,05) were established between body masses of chickens from group T4 in relation to T1, T2 and K group. Mortality of chickens was as followes: K-3,64%, T1- 2,50%, and T2-5,00%, T3-6,39%, and T4-3,33%. Feed conversion in all investigated groups was almost identical (K-1,91; T2-,93; T3-1,93; T4-1,94) with the exception of T1 with 1,97. In regard to production index (PI), the best results were realized by group of chickens T3 (261), followed by chickens T4 (258), K (253), and the worst results were established in chickens of groups T1 (248) and T2 (248).
AB  - U radu je dat efekat primene neekstrudiranog (T1 i T2) i ekstrudiranog (T3 i T4) kukuruznog stočnog brašna u ishrani brojlerskih pilića. U smešama kukuruz (K) je zamenjen kukuruznim stočnim brašnom u iznosu 50% (T2 i T4) i 100% (T1 i T3). Ogled je trajao 42 dana po sistemu 5 x 4 (5 tretmana x 4 ponavljanja). U svakom tretmanu je bilo po 300 pilića. Ishrana je bila ad libitum sa tri smeše: starter sa 23,30% SP i 12,78 MJ/kg ME, grover sa 20,30% SP i 13,10 MJ/kg ME, i finišer 17,70% SP i 13,25 MJ/kg ME. Rezultati ispitivanja su bili sledeći: telesne mase K-2106g, T1-2103g, T2-2112g, T3-2254g, i T4-2173g; dnevni prirast K-50,13g, T1-50,08g, T2- 50,29g, T3-53,66g, i T4-51,73g; mortalitet pilića K-3,64%, T1-2,50%, T2- 5,00%, T3-6,39%, i T4-3,33%; Konverzija hrane K-1,91 kg/kg, T1-1,97 kg/kg, T2-1,93 kg/kg, T3-1,93 kg/kg, i T4-1,94 kg/kg. Pokazalo se da su razlike u završnoj telesnoj masi pilića iz T3, u odnosu na T1, T2, T4 i K grupe, bile statistički visoko značajne (P (lt) 0,001). Utvrđene su statistički značajne razlike (P (lt) 0,05) između telesnih masa grupe pilića T4 u odnosu na T1, T2 i K grupe. Randmani su bili ujednačeni po grupama, a razlike u sadržaju abdominalne masti u trupovima su bile minimalne ali nešto niže kod petlića i kojica grupe T1 i petlića T2. Razlike su bile su statistički značajne.
