Genome-wide association study of growth in crossbred beef cattle.
Chromosomal regions harboring variation affecting cattle birth weight and BW gain to 1 yr of age were identified by marker association using the highly parallel BovineSNP50 BeadChip (50K) assay composed of 54,001 individual SNP. Genotypes were obtained from progeny (F(1); 590 steers) and 2-, 3-, and 4-breed cross grandprogeny (F(1)(2) = F(1) x F(1); 1,306 steers and 707 females) of 150 AI sires...
متن کاملGenome-Wide Association for Growth Traits in Canchim Beef Cattle
Studies are being conducted on the applicability of genomic data to improve the accuracy of the selection process in livestock, and genome-wide association studies (GWAS) provide valuable information to enhance the understanding on the genetics of complex traits. The aim of this study was to identify genomic regions and genes that play roles in birth weight (BW), weaning weight adjusted for 210...
متن کاملPost-partum anoestrus in dairy cows: a review.
In modern high-yielding dairy herds fertility is of major economic importance. In order to gain maximum profit, calving intervals should not exceed 365 days. The achievement of a 365-day calving interval requires an early resumption of ovarian activity, an excellent oestrus detection, and a high first-service conception rate. Especially the inability to detect oestrus and to mate the cows by 60...
متن کاملGenome-wide Association Study to Identify Genes and Biological Pathways Associated with Type Traits in Cattle using Pathway Analysis
Extended Abstract Introduction and Objective: Type traits describing the skeletal characteristics of an animal are moderately to strongly genetically correlate with other economically important traits in cattle including fertility, longevity and carcass traits. The present study aimed to conduct a genome wide association studies (GWAS) based on gene-set enrichment analysis for identifying the ...
متن کاملGenome-wide association study for behavior, type traits, and muscular development in Charolais beef cattle.
Behavior, type traits, and muscular development are of interest for beef cattle breeding. Genome-wide association studies (GWAS) enable the identification of candidate genes, which enables gene-based selection and provides insight in the genetic architecture of these traits. The objective of the current study was to perform a GWAS for 3 behavior traits, 12 type traits, and muscular development ...
