| Abstract |
| Survival records and pedigree information from 3056 Raeini kids born between 1993 and 2004 were used to determine genetic and non-genetic factors affecting kids survival. To estimate the effect of environmental factors on survival kids used GLM procedure from SAS. The variances and genetic parameters were estimated by the Restricted Maximum Likelihood method (REML), with single trait animal models. The models included fixed factors that had significant effects and random direct genetic, maternal genetic and residual effects. overall mean of kids survival were 0/90 , 0/95 , 0/98 , 0/98 and 0/98 from birth up to 10 , 30 , 60 , 90 and 120 days of age, respectively. Direct and maternal heritability estimates of kid survival ranged from 0/01 to 0/11 and 0/01 to 0/04 , respectively. Direct heritability increased with age of lamb, while maternal heritability decreased. The results of this study suggest that progress in survival traits could be possible through managerial strategies and genetic selection. |
