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

We hypothesized the manner that heifers achieve puberty may indicate their future
reproductive longevity. Heifers with discontinued or delayed cyclicity during puberty …

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 …

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

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 …

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 …

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

Background Reproductive efficiency has a great impact on the economic success of pork
production. Gilts comprise a significant portion of breeding females and gilts that reach …

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 …

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