Zebu animals (Bos indicus) are known to take longer to reach puberty compared with taurine
animals (Bos taurus), limiting the supply of animals for harvest or breeding and impacting …

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 …

Selection for bulls that would reach puberty early reduces the generation interval and
increases fertility and herd productivity. Despite its economic importance, there are few QTL …

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

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 …

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 …

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 …

Simple Summary Reproductive performance has direct economic implications on the beef
cattle industry. The majority of Zebu breeds (eg, Nellore; Bos taurus indicus) have poor …

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 …

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 …
