Genome-wide association and genomic prediction for scrotal circumference in Hereford and Braford bulls
(2021-09-15)
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: ...
Genome-wide association study identified genomic regions and putative candidate genes affecting meat color traits in Nellore cattle
(2021-01-01)
Single and multiple-trait GWAS were conducted to detect genomic regions and candidate genes associated with meat color traits (L*, lightness; a*, redness; b*, yellowness) in Nellore cattle. Phenotypic records of 5000 ...
Genome-wide CNV analysis reveals variants associated with growth traits in Bos indicus
(2016-06-01)
Background: Apart from single nucleotide polymorphism (SNP), copy number variation (CNV) is another important type of genetic variation, which may affect growth traits and play key roles for the production of beef cattle. ...
Estimates of genomic heritability and genome-wide association study for fatty acids profile in Santa Inês sheep
(BioMed Central, 2018)
Abstract
Background
Despite the health concerns and nutritional importance of fatty acids, there is a relative paucity of studies in the literature that report genetic or ...
Genome-wide association analysis of feed intake and residual feed intake in Nellore cattle
(Biomed Central Ltd., 2014-02-11)
Background: Feed intake plays an important economic role in beef cattle, and is related with feed efficiency, weight gain and carcass traits. However, the phenotypes collected for dry matter intake and feed efficiency are ...
Genome-wide scan highlights the role of candidate genes on phenotypic plasticity for age at first calving in Nellore heifers
(2020-12-01)
Age at first calving (AFC) plays an important role in the economic efficiency of beef cattle production. This trait can be affected by a combination of genetic and environmental factors, leading to physiological changes ...
