Sperm quality improvement of cryopreserved boar semen through colloidal centrifugation gradient
Czech Journal of Animal ScienceBoar semen cryopreservation is limited due to the lower thermal shock resistance of sperm cells. A colloidal centrifugation gradient is an enhancement to cryopreservation that could improve the frozen boar semen quality.

Cryopreservation of boar semen [PDF]
, 2000 The world’s pig population is consistently being upgraded through the international trade of superior genetics. The two major systems that are used for this purpose are the transport of live animals and the export of frozen boar semen. The main limiting factors for a wider use of frozen-thawed (FT) boar semen are low fertility levels of FT in ...

An Outbreak of Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) in a German Boar Stud: A Retrospective Analysis of PRRSV Shedding in Boar Semen [PDF]
Veterinary SciencesThe porcine reproductive and respiratory syndrome virus (PRRSV) causes high economical costs due to reduced productivity and losses in pig production. The virus can infect sow herds through various routes.

Recent development in freezing strategies of pig semen-A review
Indian Journal of Animal Sciences, 2022 Of late studies on frozen thawed boar semen have dramatically improved boar semen cryopreservation technique, albeit the commercial application of cryopreserved boar semen has not yet been popular. Some studies claimed successful fertility/ fertilization

Colloid Centrifugation of Boar Semen [PDF]
Reproduction in Domestic Animals, 2011 ContentsColloid centrifugation of boar semen has been reported sporadically for at least the last two decades, beginning with density gradient centrifugation (DGC) and progressing more recently to single layer centrifugation (SLC). Single layer centrifugation through a species‐specific colloid has been shown to be effective in selecting the best ...

Recent advances in boar semen cryopreservation [PDF]
Bioscientifica Proceedings, 2020 Since 35 years ago boar semen has been frozen and used for artificial insemination (AI). However, fertility of cryopreserved porcine sperm has consistently been low as boar sperm are more sensitive to cellular stress imposed by changing osmotic balance, oxidative stress, low-temperature exposure, cryo-protectant intoxication etc.

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,
