Measures of heifer fertility are economically relevant traits for beef production systems and
knowledge of candidate genes could be incorporated into future genomic selection …

The aim of this study was to identify SNP markers that associate with variation in beef heifer
reproduction and performance of their calves. A genome-wide association study was …

Fertility traits measured early in life define the reproductive potential of heifers. Knowledge of
genetics and biology can help devise genomic selection methods to improve heifer fertility …

The development of replacement heifers is at the core of cow-calf beef production systems.
In 2020, the USDA, National Agricultural Statistics Service reported 5.771 million beef …

ABSTRACT Brangus [3/8 Brahman (Bos indicus)× 5/8 Angus (Bos taurus); n≈ 800] heifers
from 67 sires were used to estimate heritability and conduct a genome-wide association …

Heifer conception rate (HCR) is defined as the percentage of inseminated heifers that
become pregnant at each service. The genome-wide association analyses in this study …

Background An important goal of Zebu breeding programs is to improve reproductive
performance. A major problem faced with the genetic improvement of reproductive traits is …

The ability of livestock to reproduce efficiently is critical to the sustainability of animal
agriculture. Antral follicle count (AFC) and reproductive tract scores (RTS) can be used to …

The promise of genomic selection is accurate prediction of the genetic potential of animals
from their genotypes. Simple DNA tests might replace low-accuracy predictions for …

The genetics of reproduction is poorly understood because the heritabilities of traits currently
recorded are low. To elucidate the genetics underlying reproduction in beef cattle, we …
