Estimation of Genetic Parameters and Non-Genetic factors for Birth Weight and Reproduction Traits of Pure Jersey Dairy Cattle at Adea Berga Research Station

Abstract:

This study was conducted to estimate non-genetic factors and genetic parameters for birth weight and reproduction traits of pure Jersey dairy cattle at Adea Berga Research Station. A total of 11,794 pure Jersey dairy cattle performance records which were collected from 1986 to 2019 was used for the study. The General Linear Model (GLM) procedures of SAS software were used to determine the effects of non-genetic factors. Genetic parameters and variance components were estimated by Average Information Restricted Maximum Likelihood (AIREML) algorithm using WOMBAT software fitting animal models. The results indicated that the the overall least square means (± SE) of age at first service (AFS), age at first calving (AFC), days open (DO), calving interval (CI), number of service per conception (NSC) and birth weight (BW) were 22.88 ± 0.20 months, 32.68 ± 0.1 9 months, 205.53 ± 4.48 days, 479.80 ± 4.45 day, 2.01 ± 0.02 and 22.3 ± 0.09kgs, respectively. Year of birth had highly significant (P
