Fertility is among the most important economic traits in dairy cattle. Genomic prediction for cow fertility has received much attention last decade, while bull been largely overlooked. The goal of this study was to assess genomic using markers with large effect and functional annotation data. Sire conception rate (SCR) used as a measure service sire fertility. Dataset consisted 11.5 k U.S. Holstein bulls SCR records about 300 single nucleotide polymorphism (SNP) markers. analyses included...
Abstract Background Achieving rapid genetic progress while maintaining adequate diversity is one of the main challenges facing dairy industry. The increase in inbreeding can be used to monitor loss diversity. Inbreeding tends proportion homozygous loci, some which cause homozygosity recessive alleles that results reduced performance. This phenomenon known as depression and most prominent on fitness-related traits, such male fertility. Traditionally, has been monitored using pedigree...
Summary Bovine leukemia virus ( BLV ) infections, causing persistent lymphocytosis and lethal lymphosarcoma in cattle, have reached high endemicity on dairy farms. We observed extensive inter‐individual variation the level of infection LI by assessing differences proviral load peripheral blood. This phenotypic appears to be determined host genetics variants, especially those located Bo LA ‐ DRB 3 MHCII molecule. performed an association study using sequencing‐based typed BOLA alleles from...
Bovine leukemia virus (BLV) infection is omnipresent in dairy herds causing direct economic losses due to trade restrictions and lymphosarcoma-related deaths. Milk production drops increase the culling rate are also relevant usually neglected. The BLV provirus persists throughout a lifetime an inter-individual variation observed level of (LI) vivo. High LI strongly correlated with disease progression transmission among herd mates. In context high prevalence, classical control strategies...
Research on loci influencing milk production traits of dairy cattle is one the main topics investigation in livestock. Many genomic regions and polymorphisms associated with have been reported worldwide. In this context, purpose study was to identify candidate yield Argentinean cattle. A database genes single nucleotide (SNPs) for composition developed. Thirty-nine SNPs belonging 22 were genotyped 1643 animals (Holstein Holstein x Jersey). The genotypes obtained subjected association studies...
