Abstract

In this study, performance records of the native Fars chickens collected by the FARS NATIVE FOWLs Breeding Centers, during 1988 to 1999 were analyzed. The multi-trait ANIMAL MODEL and restricted maximum likelihood procedure was used to estimate HERITABILITY, correlations between traits and breeding values. Estimates of heritabilities were 0.68, OAO,0.64 and OA9 for body weight at 12 weeks (BW12), egg number (EN), egg weight (EW) and age of sexual maturity(ASM), respectively. The Cumulative genetic gains, after 8 generations of selection, expressed by regression coefficients of breeding values on generation for BW12, EN, EW and ASM, were 22.73,0.17,0.04 and -1.38, respectively. A pedigree file collected on 21245 female and male birds was used to calculate the INBREEDING coefficient. The average INBREEDING coefficients for all birds were 0.048%, and ranged from zero to 25%. In this population, 8% of the birds were inbred, and average INBREEDING coefficients for inbred bird was 0.67% Due to relatively high HERITABILITY of productive and reproductive traits, it is possible to achieve more progress in these traits using appropriate genetic selection.
