One of the most frequently isolated bacteria in porcine semen was Escherichia coli. Overgrowth by contaminant bacteria such as E. coli has a deleterious effect on semen quality and longevity. The objective of this study was to determine the effects of E. coli isolated from porcine semen on sperm motility, viability, semen pH, and field fertility in sow. Semen samples were prepared using BTS extender that did not contain antibiotics. E. coli ...

Ascorbic acid 2-glucoside (AA-2G), a stable ascorbate derivative, is a prominent antioxidant characterized by its stability in an oxidative environment. The objective of this study was to evaluate the effect of AA-2G on sperm motility, viability and acrosome integrity during semen cryopreservation in Korean native pig. Semen samples were diluted into a freezing extender (LEY) containing lactose hen-egg yolk with glycerol and Orvus Es Paste (OEP) and loaded in 0.5 ml plastic st...
