Effect of L-carnitine on sperm quality during liquid storage of boar semen [PDF]
Asian-Australasian Journal of Animal Sciences, 2020 Objective This study was conducted to investigate the effect of L-carnitine on the pig semen characteristics during storage. Methods Spermatozoa samples were examined for spermatozoa quality and then randomly divided into 5 groups: 0 (control), 12.5, 25,

Protein kinase C activity in boar sperm [PDF]
Andrology, 2017 SummaryMale germ cells undergo different processes within the female reproductive tract to successfully fertilize the oocyte. These processes are triggered by different extracellular stimuli leading to activation of protein phosphorylation. Protein kinase C (PKC) is a key regulatory enzyme in signal transduction mechanisms involved in many cellular ...

Artificial insemination with frozen‐thawed boar sperm [PDF]
Molecular Reproduction and Development, 2017 Artificial insemination with frozen‐thawed semen in pigs is not a routine technique; its use is restricted to specific cases, such as preservation of valuable genetic material (germplasm banks), safety strategies in case of natural disasters, long‐distance transport of sperm, and in combination with sex‐sorting.

Aquaporins 7 and 11 in boar spermatozoa : detection, localisation and relationship with sperm quality [PDF]
, 2014 Aquaporins (AQPs) are integral membrane water channels that allow transport of water and/or small solutes across cell membranes. Although water permeability is known to play a critical role in mammalian cells, including spermatozoa, little is known about

Assessment of quality in specific fractions of Large White Yorkshire boar semen [PDF]
Journal of Veterinary and Animal Sciences, 2021 Boar semen is voluminous and ejaculated as jets or fractions of pre-sperm, sperm rich (SRF) and post-sperm rich fractions. Recent studies have reported more resilient characteristics of sperm in initial portions of SRF towards cold shock and ...
