Background Identification of single nucleotide polymorphisms (SNPs) for specific genes
involved in reproduction might improve reliability of genomic estimates for these low …

Advancing the age at which puberty and subsequent sexual maturation is attained in cattle
is central to the reproductive and economic efficiency of both beef and dairy production …

A current challenge in genetic improvement of cattle is to identify genomic selection
strategies that could work across breeds. Breed differences, scarcity of data, and lack of …

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 …

The genetics of reproduction is poorly understood because the heritabilities of traits currently
recorded are low. To elucidate the genetics underlying reproduction in beef cattle, we …

Data from developing Brangus heifers (3/8 Brahman-Bos indicus× 5/8 Angus-Bos taurus;
n≈ 802 from 67 sires) registered with International Brangus Breeders Association were …

The objective of this study was to perform a genome-wide association study (GWAS) to
detect chromosome regions associated with indicator traits of sexual precocity in Nellore …

Insulin‐like growth factor I (somatomedin C)(IGF 1) influences gonadotrophin‐releasing
hormone (G n RH) neurons during puberty, and G n RH release guides pubertal …

ABSTRACT Brangus [3/8 Brahman (Bos indicus)× 5/8 Angus (Bos taurus); n≈ 800] heifers
from 67 sires were used to estimate heritability and conduct a genome-wide association …

Eighty-seven cows were GPS (Global Positioning System) tracked for 1 to 3 months in
