Fertility is a critically important factor in cattle production because it directly relates to the
ability to produce the offspring necessary to offset costs in production systems. Female …

Before fertility traits were incorporated into selection, dairy cattle breeding primarily focused
on production traits, which resulted in an unfavorable decline in the reproductive …

Background Genome-wide association studies (GWAS) are a powerful tool for detecting
genomic regions explaining variation in phenotype. The objectives of the present study were …

Background Fertility is considered an important economic trait in dairy cattle. Most studies
have investigated cow fertility while bull fertility has received much less consideration. The …

Fertility is one of the most economically important traits in both beef and dairy cattle
production; however, only female fertility is typically subjected to selection. Male and female …

Background Genetic progress for fertility and reproduction traits in dairy cattle has been
limited due to the low heritability of most indicator traits. Moreover, most of the quantitative …

In brief The first week of gestation is a period of major pregnancy loss in cattle, this study
reveals that the male plays a key role in regulating embryonic development during this time …

Bull fertility is an important economic trait in sustainable cattle production, as infertile or
subfertile bulls give rise to large economic losses. Current methods to assess bull fertility are …

Genetic variants underlying reduced male reproductive performance have been identified in
humans and model organisms, most of them compromising semen quality. Occasionally …

The service sire has been recognized as an important factor affecting herd fertility in dairy
cattle. Recent studies suggest that genetic factors explain part of the difference in fertility …
