Heifer early calving (HC) plays a key role in beef cattle herds' economic sustainability and
profitability by reducing production costs and generation intervals. However, the genetic …

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 …

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 …

Puberty is a complex physiological event by which animals mature into an adult capable of
sexual reproduction. In order to enhance our understanding of the genes and regulatory …

We performed a genome‐wide mapping for the age at first calving (AFC) with the goal of
annotating candidate genes that regulate fertility in Nellore cattle. Phenotypic data from 762 …

The liver plays a central role in metabolism and produces important hormones. Hepatic
estrogen receptors and the release of insulin-like growth factor 1 (IGF1) are critical links …

The age at first calving has a great economic impact on the beef cattle system and calving at
24 months is an objective of selection for a more efficient herd. However, an age at first …

This study aimed to perform a genome-wide association analysis (GWAS) using the
Random Forest (RF) approach for scanning candidate genes for age at first calving (AFC) in …

Puberty onset is a developmental process influenced by genetic determinants, environment,
and nutrition. Mutations and regulatory gene networks constitute the molecular basis for the …

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 …
