Abstract:

The present study was undertaken with the objective to analyze the effect of age on various semen characteristics based on 11,008 ejaculates from 25 Hallikar bulls over a period of 15 years (January 1999 to December 2013). The data on semen collection from individual bulls were sub-clustered under four age groups namely 2-3 years, 3-5 years, 5-7 years and above 7 years. The study concludes that the semen production in Hallikar bulls is influenced by the factor age and has revealed a significant (P<0.05) effect of age on spermiogram (except initial motility).
