The present equine genetic variation mirrors the deep influence of intensive breeding
programs during the last 200 years. Here, we provide a comprehensive current state of …

Simple Summary The genetic origins behind reproductive traits are still far from clear: this is
especially true in horses, where the lack of objective reproductive phenotypes (particularly in …

Background Excessive inbreeding increases the probability of uncovering homozygous
recessive genotypes and has been associated with an increased risk of retained placenta …

In brief Adverse trends in reproductive function are a concern in humans, companion,
livestock, and wildlife species. This study indicates that equine populations are at risk of a …

Simple Summary The stallion is a horse like any other horse, and social interactions are an
important part of daily life. Although many free-roaming stallions fulfil their life's purpose …

The objectives of this study were to establish baseline information for seminal traits in
Lusitano stallions, to assess the impact of inbreeding, interval between collections and age …

Horses are non-ruminant, herbivorous mammals, been used through history for various
purposes, with a gut microbiota from cecum to the colon, possessing remarkable …

The effect of inbreeding depression on sperm motility is well documented, but its influence
on sperm morphometry has been scarcely examined to date. Here, we combined the use of …

Acrosomal dysfunction has been considered as a cause of subfertility in males of different
species, including stallions. A subset of subfertile stallions with acrosomal dysfunction is …

Allele a variant at a particular region of DNA. Genetic load deleterious genetic variation often
