Abstract

In this study, the records of survival of 3056 kids related to the breeding station of Raini Cashmere goat were used during years 1993-2004. These records were collected in Raein Breeding station located in the Baft city, Kerman province, Iran. The data were analyzed using linear and hazard ratio models with Weibul function. These models included fixed factors such as year and month of birth, sex, type, age of dam and birth weight as quadratic covariate, and direct additive genetic, maternal additive genetic, maternal permanent environmental and residual random effects. Genetic parameters were estimated using restricted maximum likelihood procedure and different animal models contained with and without maternal and common environmental effects and sire model. The direct heritability of length of life and survival rate estimated from different linear models was low (0.01 to 0.06). The estimates of heritability in logarithmic scale, original scale and effective heritability obtained from sire and animal models with Weibull function were medium to high (0.17 to 0.70) and higher than analogous values estimated by different linear models. Medium estimates show that genetic and non-genetic factors affect survival. Hence, to improve these traits, selecting beside suitable management are necessary.
