Objective of the research was to investigate the effect of genotype on production and slaughter properties of broiler chickens. The usual technology of broiler production was implemented, therefore fattening lasted 42 days. Trial included total of 2070 broiler chickens of following hybrids: Cobb 500, Ross 308 and Hubbard Classic. Chickens of genotypes Cobb 500 and Ross 308 realized significantly higher average body masses compared to Hubbard chickens. The highest mortality rate in the trial was recorded in Hubbard genotype. Chickens Cobb 500 and Ross 308 had the same feed conversion and statistically insignificant differences in production indices, whereas the values of these parameters in Hubbard chickens were significantly less favourable. The breast depth as carcass conformation measure showed no statistically significant differences between genotypes. Significantly higher values of breast angle were established in chickens of Cobb 500 compared to other two genotypes, whereas the hi...ghest values of thigh girth and the metatarsus length were established in Ross 308 chickens. Better slaughter results were obtained in carcasses of Cobb 500 genotype, chickens of both genders. Share of abdominal fat in percentage was similar in all genotypes, so the genotype had no significant effect on variation of this trait.
Cilj istraživanja bio je da se ispita uticaj genotipa na proizvodne i klanične karakteristike brojlerskih pilića. Primenjena je uobičajena tehnologija gajenja tako da je tov trajao 42 dana. Ogledom je obuhvaćeno ukupno 2070 brojlerskih pilića hibrida: Cobb 500, Ross 308 i Hubbard Classic. Pilići genotipa Cobb 500 i Ross 308 su postigli značajno veće prosečne telesne mase od pilića genotipa Hubbard. Najveći procenat mortaliteta u toku ogleda uočen je kod genotipa Hubbard. Istu konverziju hrane i statistički neznačajno različite proizvodne indekse postigli su pilići Cobb 500 i Ross 308, dok su vrednosti ovih parametara kod pilića Hubbard bile značajno nepovoljnije. Dubina grudi kao mera konformacije trupa se nije statistički značajno razlikovala među genotipovima. Značajno veće vrednosti grudnog ugla imali su pilići Cobb 500 u odnosu na ostala dva genotipa, dok su najveće obime bataka i najveće dužine piska imali pilići Ross 308. Bolji klanični rezultati su dobijeni na trupovima oba pola... genotipa Cobb 500. Procentualno učešće abdominalne masti je slično kod genotipova, tako da genotip nije imao značajan uticaj na variranje ove osobine.
