Abstract
In this study, total number of 4817, 1913, 1515, 6249, 1871, 1532, 1208 records of birth weight, weight of 3 and 12 month age, cashmere weight, total number of lambs born, total number of lambs weaned and lambing interval in Raienian cashmere goat were used. These records were collected in Baft station from 1989 to 2006. The animal model was used for genetic evaluation and estimation of genetic and phenotypic correlations for these traits. Heritability above was estimated 0.24, 0.07, 0.20, 0.17, 0.06, 0.08 and 0.03, respectively on the basis of the best model for each trait. Genetic correlation between birth weight and12 month weight, birth weight and cashmere weight, 3month weight and total number of lambs weaned, 3month weight and total number of lambs born, 12 month weight and cashmere weight, 12month weight and total number of lambs born, 12 month weight and total number of lams weaned, 12month weight and lambing interval, lambing interval and total number of lambs born, lambing interval and total number of lambs weaned, was estimated 0.27, 0.072, 0.02, -0.16, 0.28, 0.10, -0.27, -0.12, 0.30 and 0.42, respectively and phenotypic correlation was estimated 0.23, 0.056, 0.066, 0.07, 0.20, 0.01, -0.54, -0.43, 0.02 and 0.04 respectively, using Bivariate analaysis.
