Accuracy of genome-wide imputation in Braford and Hereford beef cattle [PDF]

BMC Genetics, 2014
Strategies for imputing genotypes from the Illumina-Bovine3K, Illumina-BovineLD (6K), BeefLD-GGP (8K), a non-commercial-15K and IndicusLD-GGP (20K) to either Illumina-BovineSNP50 (50K) or to Illumina-BovineHD (777K) SNP panel, as well as for imputing from 50K, GGP-IndicusHD (90iK) and GGP-BeefHD (90tK) to 777K were investigated.

Genotype by environment interaction for tick resistance of Hereford and Braford beef cattle using reaction norm models [PDF]

Genetics Selection Evolution, 2016
The cattle tick is a parasite that adversely affects livestock performance in tropical areas. Although countries such as Australia and Brazil have developed genetic evaluations for tick resistance, these evaluations have not considered genotype by environment (G*E) interactions.

Linkage disequilibrium, persistence of phase and effective population size estimates in Hereford and Braford cattle [PDF]

BMC Genetics, 2016
The existence of moderate to high levels of linkage disequilibrium (LD) between genetic markers and quantitative trait loci (QTL) affecting traits of interest is fundamental for the success of genome-wide association (GWAS) and genomic selection (GS) studies.

Genome-wide association and genomic prediction for scrotal circumference in Hereford and Braford bulls

Theriogenology, 2021
Scrotal circumference (SC) is widely used as a selection criterion for bulls in breeding programs, since it is easily assessed and correlated with several desirable reproductive traits. The objectives of this study were: to perform a genome-wide association study (GWAS) to identify genomic regions associated with SC adjusted for age (SCa) and for both ...
