RESTRICTED SELECTION INDEX FOR GROWTH TRAITS OF SHAMI KIDS

A Restricted Selection Index was constructed to genetically evaluate animals using a dataset composed of body weights Shami kids at the ages birth, weaning, and 6-month. The variance-covariance matrix (VCV) generated used estimate genetic parameters for index construction after adjusting fixed effects; year, birth month, kid sex, type (single, twin or triplet) doe age, kidding (KW), (BWT) weaning (WWT) as covariates. General Linear Model Maximum Likelihood methods were BLUE effects variance components random effects, respectively. BW 3.6 ± 0.017, WW 16.8 0.10, weight 6 months (MWT) 26.7 0.21 Kg. With exception buck origin all tested factors significantly affected growth traits. Heritability BWT, WWT, MWT 0.70 0.32 0.075, 0.41 0.12, repeatability 0.78, 0.35, 0.47, Genetic phenotypic correlations positive significant between BWT WWT MWT. restricted selection increasing with restriction on yielded strong correlation coefficient (rIA) merit 0.54 (p<0.01).
