Featured Blog: Biofilms in Mare Reproduction

February 27, 2015

A biofilm has been proposed to have a significant role in chronic infections in the horse. It has been suggested for over a decade that chronic uterine infections resistant to antimicrobials may be due to biofilm production. The involvement of a biofilm in cases of bacterial endometritis has not been clearly elucidated, but many reproductive specialists suspect a biofilm plays a significant role in infectious endometritis. In this article Dr. Ryan Ferris, a board certified theriogenologist from Colorado State University, explains the lifestyles of bacteria, how a biofilm is formed, how they protect bacteria and their implications on equine reproduction.

Featured Question

Is frozen semen less fertile than fresh or cooled semen?

Fertility of frozen semen is highly dependent upon the stallion. In one of the few published trials in which the fertility of fresh, cooled and frozen semen was evaluated from the same stallion, the fertility of cooled semen was less than fresh and the fertility of frozen semen was slightly less than cooled semen. However, in other studies based on a large number of inseminations, the fertility of cooled and frozen semen was found to be similar and both were slightly less than fresh. In 2010, for three breeding farms in MD managing a combined total of 36 stallions shipping either cooled or frozen semen to a total of 648 mares, the first cycle pregnancy rate was 63% for cooled semen and 60% for frozen semen. The end of season pregnancy rate was 79% for cooled semen and 76% for frozen semen. Demonstrating that in the general population of horse breeders comparable results can be achieved with cooled and frozen semen.
