Camellia oil with its rich in fatty acids enhances post-thawed boar sperm quality [PDF]
Acta Veterinaria ScandinavicaBackground Boar sperm are highly susceptible to specific conditions during cryopreservation, leading to a significant decrease in their fertilizing potential due to damage to their membranes.

Validation of the polysemen admixture on viability and acrosomal morphology of boar spermatozoa
Online Journal of Health & Allied Sciences, 2007 Semen were collected using artificial vagina (AV), from 5 large white boars aged 2-2.5 years twice a week for 16 weeks in each of the two seasons, early rainy (ER) and late rainy (LR) seasons, to determine the effects of multiple semen pool admixture on ...

Cysteine improves boar sperm quality via glutathione biosynthesis during the liquid storage [PDF]
Animal Bioscience, 2022 Objective Sperm is particularly susceptible to reactive oxygen species (ROS) stress. Glutathione (GSH) is an endogenous antioxidant that regulates sperm redox homeostasis.

Frontiers in Veterinary Science, 2021 Cryopreservation induces sperm cryoinjuries, including physiological and functional changes. However, the molecular mechanisms of sperm cryoinjury and cryoresistance are still unknown. Cryoresistance or the freeze tolerance of sperm varies across species,

Pig Spermatozoa Defect in Acrosome Formation Caused Poor Motion Parameters and Fertilization Failure through Artificial Insemination and Fertilization [PDF]
Asian-Australasian Journal of Animal Sciences, 2014 The selection of morphologically normal spermatozoa is critical to obtain high breeding performances in boar breeding farms and artificial insemination (AI) centers. Parameters for the selection of semen mainly include total sperm motility, concentration,

Sperm capacitation as a predictor of boar fertility
Molecular Reproduction and Development, 2023 AbstractPrediction of a boar's fertility level has great economic importance for sow herds. After standard sperm morphology and motility metrics are met, approximately 25% of boars have less than 80% conception rates. Due in part to the many factors involved in the fertilization process, a multifactorial model incorporating multiple relevant sperm ...

Scrotal insulation and sperm production in the boar [PDF]
Molecular Reproduction and Development, 2017 Seasonal infertility is a limiting factor in boar fertility, and is increasingly important as climate changes. Spermatogenesis in the boar produces 256 spermatozoa per type A1 spermatogonium, but the process is inefficient such that only 10–30% of these potential spermatozoa are actually produced.
