The conservation of genetic resources in pig breeds, notably the Iberian pig, is crucial for improvement and sustainable production. Prolonged storage liquid nitrogen (LN
Cryopreservation of porcine spermatozoa is detrimental due to their high sensitivity cold shock, leading changes akin capacitation, known as cryocapacitation. These changes, including the acrosomal reaction, hypermotility induction, and protein phosphorylation, might be influenced by presence progesterone in seminal plasma egg yolk, used most freezing extenders. We tested effect various concentrations added extenders (1, 10, 100 μg/mL). At μg/mL, decreased proportion straightness tended...
Abstract This study investigates the impact of bovine serum albumin (BSA) inclusion in thawing extender on boar sperm quality. Thawing protocols cryopreservation are vital, yet underexplored. It has been determined that BSA can interact with membranes, stabilizing them and preventing damage during freezing process, for this reason it could also have a beneficial effect thawing. Our explores modifications conventional Beltsville solution, incorporating at different concentrations (0.005,...
Abstract Sperm capacitation is a crucial step towards the acquisition of fertilizing capacity. Despite attempts to mimic in vivo situation, there still lack standardization vitro techniques. Bicarbonate and serum albumin (BSA) are routinely used, although controversial results reported regarding optimal concentration each compound. In addition, whether caffeine needed on media boar sperm remains be elucidated. Here, 18 commercial artificial insemination doses were used test different...
