Genome wide association study for feed efficiency traits in beef cattle using CNV
The purpose of this study was: (i) to validate and detect copy number variations (CNV) in the cattle genome, and (ii) to find associations between CNV and feed efficiency traits. Average daily gain and dry matter intake were obtained from 3,884 beef cattle. Animals were genotyped with the panels of 50,000 single nucleotide polymorphisms (SNP) or 770,000 SNP. The log R ratio (LRR) was used as an...

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 کاملSystems genetics and genome-wide association approaches for analysis of feed intake, feed efficiency, and performance in beef cattle.
Feed intake, feed efficiency, and weight gain are important economic traits of beef cattle in feedlots. In the present study, we investigated the physiological processes underlying such traits from the point of view of systems genetics. Firstly, using data from 1334 Nellore (Bos indicus) cattle and 943,577 single nucleotide polymorphisms (SNPs), a genome-wide association analysis was performed ...
متن کاملGenome-wide association study for feed efficiency traits using SNP and haplotype models.
Feed costs comprise the majority of variable expenses in beef cattle systems making feed efficiency an important economic consideration within the beef industry. Due to the expense of recording individual feed intake phenotypes, a genomic-enabled approach could be advantageous towards improving this economically relevant trait complex. A genome-wide association study (GWAS) was performed using ...
متن کاملInitial Genome-Wide Association Study of Feed Intake Related Traits in Beef Cattle
Importance of Feed Efficiency The ability to improve the utilization of nutrients has tremendous potential to improve profitability. It has been estimated that a 10% improvement in performance (gain) would increase profit by 18%, while a 10% improvement in efficiency could improve profit by upwards of 43%. It has also been estimated that a 10% improvement in feed efficiency (assumed to be a 2 l...
