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 …

Global demand for animal proteins is increasing, necessitating increased efficiency of global
food production. Improving reproductive efficiency of beef cattle, especially bull fertility, is …

Fertility plays a key role in the success of calf production, but there is evidence that
reproductive efficiency in beef cattle has decreased during the past half-century worldwide …

Sperm motility is the main index used to assess the quality of bull semen. It may also be
used to evaluate the fertility potential of bulls. Protein-coding mRNA and long noncoding …

Sperm motility is directly related to the ability of sperm to move through the female
reproductive tract to reach the ovum. Sperm motility is a complex trait that is influenced by …

Intensive selection for improved productivity has been accompanied by an increase in
inbreeding rates and a reduction in genetic diversity. The increase in inbreeding tends to …

The aim of this study was to estimate genotype by time-lagged heat stress (HS) variance
components as well as main and interaction SNP-marker effects for maternal HS during the …

Background Twenty-five phenotypes were measured as indicators of bull fertility (1099
Brahman and 1719 Tropical Composite bulls). Measurements included sperm morphology …

Circular RNAs (circRNAs) are emerging as a novel class of noncoding RNAs which potential
role as gene regulators is quickly gaining interest. circRNAs have been studied in different …

Sperm quality traits routinely collected by artificial insemination (AI) center for rams progeny
test are related with the capacity to produce sperm doses for AI and, in more or less grade …
