Air Contact and the pH of Extended Porcine Semen
Artificial insemination is a routine procedure in sows. But what happens if the porcine semen is exposed to air? There are lots of effects, e.g. on the sperm motility parameters. A brandnew and very interesting and important study from Belgium.

In this study, the pH-rise during storage of extended porcine semen was examined.

This pH-rise was found to be caused by CO2-loss from the buffering system in the extender and was more pronounced with increasing air volume in the recipient.

An influence on sperm motility parameters was observed between semen samples stored in the presence of different amounts of ambient air in the recipient.

Velocity parameters and percentage motile spermatozoa were significantly lower for semen stored in recipients with higher air volume and elevated pH.

Adjusting extender preparation by avoiding air contact in commercial AI-centres may minimize the pH-rise and its influence on sperm motility.

Oral fluid and plasma oxytetracycline concentrations after i.m. administration in pigsmembers
The penetration of oxytetracycline (OTC) into the oral fluid and plasma of pigs and correlation between oral fluid and plasma were evaluated after a single intramuscular (i.m.) dose of 20 mg/kg body weight of long-acting formulation. An important study regarding one of the most popular long-acting antibiotics in pigs.
