DOI: 10.1016/j.anireprosci.2018.08.015
Abstract: The key prerequisite for successful insemination is sperm characterized to have positive values for morphological and biological variables which are determined by, among others, effective antioxidant protection during the lifespan of sperm cells. This study… read more here.

DOI: 10.1016/j.anireprosci.2020.106641
Abstract: Horses are long-day seasonal breeding animals, however, with modern stallion reproductive management it is important for collection of semen during periods that are not part of the traditional breeding season. This study was conducted to… read more here.

DOI: 10.1016/j.cryobiol.2021.07.009
Abstract: The quality of fresh or thawed sperm in stallions has been generally determined by the viability and total and progressive motility of the sperm. Today, the expression of ProAKAP4, a protein present in the flagellum… read more here.

DOI: 10.1016/j.jevs.2017.03.225
Abstract: Abstract Seminal cryopreservation provides several advantages in horse breeding. However, improvement on post‐thaw sperm survival is still necessary. One of the main factors known to impair post‐thaw quality of stallion’s sperm is the oxidative damage… read more here.

DOI: 10.1016/j.theriogenology.2021.07.008
Abstract: Different stallions exhibit a high level of variation in the ability of their sperm to survive cryopreservation. A large fraction of stallions show poor post-thaw sperm motility, and their semen is not suitable for commercial… read more here.
