Abstract

This research was undertaken to study MATERNAL EFFECTS on five PRODUCTION AND REPRODUCTION TRAITS using records collected over six generations from a selected breeder flock of native hens kept at a breeding center in Fars province, Iran. The traits were body weight at 12 weeks of age (BW12), body weight at sexual maturity (MBW), age at sexual maturity (ASM), egg number up to 32 weeks of age (EN) and egg weight at 32 weeks of age (EW). Variance components and heritabilities were estimated by the Henderson's method 3 using paternal half-sib and full-sib models and restricted maximum likelihood (REML) procedure under an animal model (AM). Heritability estimates for BW12, MBW, ASM, EN, and EW were 0.237, 0.243, 0.348, 0.258, and 0.338, respectively, based on paternal half sibs, 0.436, 0.329, 0.363, 0.172 and 0.381, respectively based on full sibs, and 0.374, 0.341, 0.352, 0.186, and 0.389, respectively, based on animal model. Comparison of the results from paternal half-sib correlation with those of full-sib correlation and animal model for body weight traits indicated that these traits may be affected by MATERNAL EFFECTS.
