Projekat:

Ključne reči: genotype; sex; interaction effect; growth traits; body weights; lamb
Sažetak
Metode odgajivanja imaju važnu ulogu u ovčarskoj proizvodnji. Od suštinskog značaja u proizvodnji mesa ovaca je održavanje genetske raznovrsnosti i varijabilnosti populacija. Cilj ovih istraživanja je da se utvrdi uticaj genotipa i pola, kao i njihovih interakcija na osobine porasta jagnjadi. Rezultati studije pokazali su da muški pol svih genotipova je dominantan u pogledu mase tela u svim uzrastima (od BWB do BW90). Najveća telesna masa (BWB) bila je kod muških grla genotipa 2 (W). Najnižu telesnu masu na rođenju, imala su ženska jagnjad genotipa 1. Masa tela pri uzrastu od 30, 60 i 90 dana, kod oba pola je bila dominantna kod genotipa 4 (PxWxF). Genotip 1 (P)- oba pola, imao je najniže vrednosti masa u svim uzrastima (BWB, BW30, BW60, BW90). Rezultati istraživanja su pokazali bolju efikasnost rasta kod muških u odnosu sa ženska grla. Rezultati fiksnih faktora i njihovog uticaju na telesnu masu jagnjadi pokazali su veoma značajan efekat genotipa (P <0,01) pri rođenju (BWB), kod uzrasta 30, 60 i 90 dana (BW30, BW60, BW90). Pol je imao visoko značajne efekte (P <0,001) kod svih uzrasta. Interakcija između genotipa i pola pokazala je veoma značajan efekat (P≤0.01) na telesnu masu pri rođenju (BWB), ali dobijene vrednosti razlika nisu bile značajne (P≥0.05) u dobi BW30, BW60 i BW90. Superiornost genotipa 4 (PxWxF) pokazala se u uzrastu od 30, 60 i 90 dana, što može biti izazov i praktična korist za farmere koji koriste ukrštanje.
