The relationship between acrosome reaction and polyunsaturated fatty acid composition in boar sperm.

open access: yesReproduction in domestic animals = Zuchthygiene, 2019
This study investigated the relationship between acrosome reactions and fatty acid composition with respect to fertility in boar sperm. The acrosome reaction was induced more than 85% by 60 mM methyl-beta-cyclodextrin (MBCD) and plasma membrane integrity

Partial purification of a boar sperm membrane protein inducing sperm agglutinating antibody

open access: yesBioscience Reports, 1990
For the development of immunological contraception, attention is being concentrated on the possibility of using a sperm membrane antigen. Boar sperm membrane was extracted with triton-X 100 and fractionated by Sephadex G-150 column chromatography. The glycosylated and nonglycosylated portions of protein peaks from the gel filtration were obtained by ...

Sperm quality improvement of cryopreserved boar semen through colloidal centrifugation gradient

open access: yesCzech Journal of Animal Science
Boar 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.
