Abstract:

Data on 106197 semen ejaculates of 310 crossbred Jersey bulls maintained at three frozen semen stations in Tamil Nadu, India were collected from the year 2002 to 2014. The effects of various non-genetic factors such as farm, ejaculate number, period of semen collection, season of semen collection and age of the bulls at collection were studied on semen quality parameters using least-squares method. The overall least-squares means for semen volume, sperm concentration, mass activity, initial sperm motility, post-thaw motility and number of doses per ejaculate were 4.03 ml, 1056.18 million per ml, 2.31, 67.08 per cent, 51.04 per cent and 172.58 doses, respectively. The effects of farm, ejaculate, period and age of the bulls were significant (P<0.05) on all semen quality parameters. Season had significant (P<0.05) effect on sperm concentration, mass activity and initial sperm motility. The farm x season and age x ejaculate interaction effects were found to have significant (P<0.05) effect on all semen quality parameters.
