Breeding soundness examinations for bulls rely heavily on the subjective, visual
assessment of sperm motility and morphology. Although these criteria have the potential to …

Reference genomes of cattle and sheep have lacked contiguous assemblies of the sex-
determining Y chromosome. Here, we assemble complete and gapless telomere to telomere …

Cattle are a well-suited “model organism” to study the genetic underpinnings of variation in
male reproductive performance. The adoption of artificial insemination and genomic …

Background Genetic causes that lead to spermatogenetic failure in patients with
nonobstructive azoospermia (NOA) have not been yet completely established. Objective To …

Context Plastics can break down into millions of microplastic (MPs,< 5 mm) particles in the
soil and ocean. These MPs can then affect the function of the reproductive system. There is …

In brief Bull fertility is an important economic trait, this study identified some DNA methylation
biomarkers that are associated with bull fertility. Abstract Subfertile bulls may cause huge …

Background Cattle are ideally suited to investigate the genetics of male fertility. Semen from
individual bulls is used for thousands of artificial inseminations for which the fertilization …

Background Reproductive performance plays an important role in animal welfare, health
and profitability in animal husbandry and breeding. It is well established that there is a …

Bull fertility is considered an indispensable trait, as far as farm economics is concerned
since it is the successful conception in a cow that provides calf crop, along with the ensuing …

Due to their unique multi-gastric digestion system highly adapted for rumination, dairy
livestock has complicated physiology different from monogastric animals. However, the …
