Abstract

This study was conducted for genetic analysis of Markhoz goats for autosomal and X chromosomes for Average Daily Gain traits from birth to yearling. The data set contained 3837 Average Daily Gain from birth to weaning (ADG1), 3467 Average Daily Gain from weaning to 6-month (ADG2), 3133 Average Daily Gain from 6-month to 9-month (ADG3) and 2726 Average Daily Gain from 9-month to 12-month (ADG4) collected during 1992-2014 in Markhoz Goat Breeding Center of Sanandaj. Fixed effects affecting the studied traits were determined using Proc GLM of the SAS 8. 2 software and variance components and genetic parameters were estimated by Average Information algorithm of Restricted Maximum Likelihood (AI-REML) using Wombat software. The most appropriate model for each trait was determined by Akaike’ s Information Criterion (AIC) test. Direct Autosomal heritability estimates for ADG1, ADG2, ADG3 and ADG4 were 0. 14± 0. 03, 0. 00± 0. 02, 0. 14± 0. 04 and 0. 06± 0. 03, respectively. X-linked direct heritability estimates for these traits were negligible values of 0. 00± 0. 02, 0. 08± 0. 02, 0. 06± 0. 02 and 0. 04± 0. 02, respectively. Maternal heritability for ADG1 and ADG3 were 0. 06± 0. 02 and 0. 04± 0. 03, respectively. Maternal permanent environmental variance for ADG3 and ADG4 were 0. 03± 0. 02. The low estimations of direct heritabilities for autosomal and sexual chromosomes were obtained in the current study, therefore direct selection for these traits would be generate a relatively slow genetic progress.
