Abstract

The data used in this study were collected from Kordy sheep breed research station, located in north of Khorasan province. The derivative free RESTRICTED MAXIMUM LIKELIHOOD procedure was used from model 8 of DFREML 1997 univariate soft ware to evaluate the mathernal effects. Maternal heritability of traits including birth weight, sucking weight, 6, 9, and 12 months weight and preweaning, post weaning, 6-12 months weights, birth to yearling, average daily gain were evaluated as follows: 0.11, 0.05, 0.01, 0.08,0.01, 0.005, 0.0001, 0.003, respectively and directed heritability of these traits using univariate ANIMAL MODEL were: 0.18, 0.06,0.29±0.06, 0.22, 0.31, 0.35, 0.05±0.02, 0.28±0.1,0.37±0.11, respectively. Sex effects, age of mother, birth type, year of birth, insemination method and management for all the traits were significant (P<0.05).
