Posters CATTLE RESIDUAL FEED INTAKE CANDIDATE GENES
One option that can be used to select cattle for improving feed efficiency is to select for genes affecting residual feed intake. Previous studies using two groups of cattle, the Trangie Angus residual feed intake (RFI) selection line cattle and the Davies Jersey x Limousin gene mapping cattle have identified five chromosomal regions or QTL that have significant effects on net feed efficiency. ...
متن کاملGenome-wide association and pathway analysis of feed efficiency in pigs reveal candidate genes and pathways for residual feed intake
Residual feed intake (RFI) is a complex trait that is economically important for livestock production; however, the genetic and biological mechanisms regulating RFI are largely unknown in pigs. Therefore, the study aimed to identify single nucleotide polymorphisms (SNPs), candidate genes and biological pathways involved in regulating RFI using Genome-wide association (GWA) and pathway analyses....
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 Studies for Net Feed Intake, Body Weight and Hip Height in Beef Cattle
We report on a genome-wide association study (GWAS) from the CRC for Beef Genetic Technologies using the 50k Illumina SNP chip. Here, we present the results for net feed intake (NFI), body weight and hip height. The aims of this analysis are to discover SNPs associated with all traits but especially NFI and to test the consistency of SNP effects across datasets and breed types using the weight ...
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...
