Estimation of breeding value, genetic variation of reproductive performance by genotyping of DRB3 gene in Holstein cows
Firas Ahmed Mahmood, Al-Waith H.K, Maad Hasani Al-Ameri
Kufa Journal for Agricultural Sciences, 2025
This study was carried out in Al-salam station for Dairy cattle, from January/11/2016 to January/11/2017, on 50 Holsein cows to study the effect of DRB3 gene information and estimate gene substitution, breeding value, dominance deviation which leads to genetic variation for services per conception and days open depending on DRB3 gene information. the results show a significant impact (p<0.05) of gene polymorphism on both traits, cows with AA genotype were better than cows with AB, BB respectively, also cows with AA genotype were better than cows with AB, BB genotype in breeding value for both traits, the variance value tended to additive variance at the expense of dominance variance for both traits, the effect was positive for the genetic replacement of the A allele compared to the B allele for both traits. This supports the selection of the A allele when it is present in homozygotes or heterozygotes for genetic data used in breeding programs and its importance for both traits.

Abstract This study aims to investigate the effect of low concentrations of sulfuric antioxidants on sperm of rams. This study was conducted in the field of sheep and goats of the Department of Livestock in the collage of Agricultural Engineering Sciences, University of Baghdad. The semen was collected using the artificial vagina at weekly rate (Pooled semen) and was subjected to different tests and then was divided into seven treatments but different concentrations of cysteine (0.5, 1mM) and glutathione (0.5, 1mM) and taurine (0.5, 1mM).The sample of the semen was diluted with Tris dilution (10: 1). The results showed that the low concentrations of glutathione, cysteine and taurine resulted in an improvement in the motility and integrity of the plasma membrane, dead sperm, DNA damage and survival sperm during the conservation period (0, 24, 48 hours).
