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 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 …

Simple Summary In this study, we investigated the association between single nucleotide
polymorphisms (SNPs) and reproductive traits in order to identify candidate genes and …

Genome-wide association studies (GWAS) are one of the best ways to look into the
connection between single-nucleotide polymorphisms (SNPs) and the phenotypic …

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 …

Zebu cattle (Bos taurus indicus) are highly adapted to tropical regions. However, females
reach puberty after taurine heifers, which affects the economic efficiency of beef cattle …

Reproductive traits are economically important for beef cattle production; however, these
traits are still a bottleneck in indicine cattle since these animals typically reach puberty at …

Background Subfertility is one challenge facing the dairy industry as the average Holstein
heifer conception rate (HCR), the proportion of heifers that conceive and maintain a …

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 …

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