Abstract

Semen from Holstein Friesian and a Holstein Friesian x Red Sindhi bull were collected at regular intervals of 4 to 5 days. Using the split ejaculate technique, samples were extended in yolk-citrate, boiled pasteurized wholemilk with and without glycerol, and boiled pasteurized skimmilk with and without glycerol at the rate of 1 volume of semen to 20 volumes of diluter. The 10 per cent glycerol was added at 3 equal parts at 10 minutes interval.

It was found out that the two bulls yielded different results. Analysis of variance revealed that the difference between bulls was insignificant. In Bull No. 1, percentage spermatozoa motility was somewhat higher in milk diluters; however, the difference was significant. The difference between milk diluters with glycerol and without glycerol was found to be highly in favor of milk with glycerol. In Bull No. 2, a highly significant differences was found between yolk-citrate diluter and milk diluters in favor of yolk-citrate. Between milk diluters with glycerol and without glycerol, the difference was found to be highly significant in favor of milk diluter with glycerol.
