Abstract

Ovo proučavanje je izvedeno u cilju determinacije najboljeg modela za procenu genetičkih parametara kod Farskog domaceg pileta korišćenjem Bejzovog i REML metoda. Proučavane su osobine: težina trupa prvog dana (BW1), težina trupa posle osam nedelja (BW8), težina trupa posle 12 nedelja (BW12), uzrast polne zrelosti (ASM), broj proizvedenih jaja (EGP) i prosecna težina jaja tokom 28-e, 30-e i 32-e nedelje starosti uključujući tri generacije 17,18 i 19, tokom 2010 i 2012. godine. Genetički parametri su procenjeni REML metodom korišćenjem WOMBAT softvera i Bejzovim modelom upotrebom MTGSAM softvera. Na osnovu AIC i DIC kriterijuma, utvrden je najbolji model. Procena direktne aditivne heritabilnosti za BW1, BW8, BW12, ASM, EGP i EGW pomocu najboljeg modela, upotrebom REML metoda bile su 0.31, 0.32, 0.29, 0.45, 0.24 i 0.22, a primenom Bejzovog metoda 0.36, 0.33, 0.30, 0.48, 0.26 i 0.25. Koeficijenti genetičke korelacije bili su u opsegu od -0.709 izmedu EGP i ASM do 0.844 izmedu BW8 i BW12 (Bejzov metod), odnosno od -0.724 izmedu ASM i EGP do 0.894 izmedu BW12 i BW8 ( REML metod). Zaključak je, na osnovu primenjenih kriterijuma, da se prvi i drugi model mogu preporuciti za analizu težine trupa (BW1, BW8 and BW12), dok su za ostale osobine (ASM, EGP and EGW), prvi, cetvrti, peti i šesti model pogodniji za procenu genetickih parametara. Bejzov model se preporučuje za ocenu genetickih parametara kod Farskog domaćeg pileta.
