Individual Variation on the Sperm Freezing Capability of Etawah Grade

Abstract

This research aims to evaluate the individual variation in the freezing capabi lity sperms of Etawah Grade bucks at Lembang Artificial Insemination Center {LAIC). Five sexually mature Etawah Grade bucks were used as sperms sources. The semen was collected using artificial vagina and was evaluated macro- and microscopically .The semen was diluted with andromed and frozen according to LAIC standard procedure . The result of the experiment indicated there was no significant difference (P>0.05) in raw semen quality, except for sperm motility. The recovery rate of sperms obtained from Efrat buck was significantly higher (P<0.05) than the other bucks. This research concluded that there was an individua l variation in freezing capability of sperm in Etawah Grade bucks.
