Puberty onset is a multifactorial process influenced by genetic determinants and
environmental conditions, especially nutritional status. Genes, genetic variations, and …

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

Introduction: Pubertal attainment is critical to reproductive longevity in heifers. Previously,
four heifer pubertal classifications were identified according to attainment of blood plasma …

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 …

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 …

Age at puberty is an important component of reproductive performance in beef cattle
production systems. Brahman cattle are typically late-pubertal relative to Bos taurus cattle …

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 …

An efficient strategy to improve QTL detection power is performing across-breed validation
studies. Variants segregating across breeds are expected to be in high linkage …

Successful development of replacement gilts determines their reproductive longevity and
lifetime productivity. Selection for reproductive longevity is challenging due to low heritability …

Harsh tropical environments impose serious challenges on poorly adapted species. In beef
cattle, tropical adaptation in the form of temperature and disease resistance, coupled with …
