Upshot of washing of Prepuce on bacterial load of semen and its consequences on semen quality in Sahiwal bulls

Abstract

Douching and cleaning of preputial cavity of bulls used for semen collection is very important for quality semen production. Preputial washing reduces the semen microbial contamination to a greater extent without harmful effect on semen quality and preservability. By effective douching and cleaning of prepuce, based on measured capacity of prepuce is of prime importance for quality semen production. It is well established that prepucial capacity may vary from breed to breed and, hence, for optimum douching and cleaning of prepuce of a bull, volume used for douching, may also vary. Hence, keeping in views of the fact the present works was conducted with aim to reduce the bacterial contamination of the fresh semen and frozen thawed semen. In the present experiment the preputial capacity was measured 431.33±21.65 ml. On comparing the overall mean, 70% of volume of fluid showed significantly lower bacterial load in comparison to other volume of wash fluid. A significantly (p<0.05) higher bacterial load was observed by full volume of fluid.
