Effect of genetic and non-genetic factors on initial seminal characteristics of Murrah buffalo bulls

摘要

The present investigation was carried out by taking data on six initial seminal attributes of 110 collection corrresponding five different ejaculates from each of 22 Murrah bulls maintained at N.D.R.I. from 1987 to 1999 except 1996. The overall leastsquares means of volume (ml), mass activity, after diluation motility percent, Motility percent after 0hr. 24 hrs and 7 days of freezing were 2.92+- 0.23, 3.41+- 0.11, 67.05+- 1.94 percent, 48.91+- 2.03 percent, 47.24+- 2.05 percent and 46.11+- 1.63 percent Least squares analysis of variance revealed significant (P<0.05) effects of bull on volume of ejaculate, mass activity and motility after 0hr. 24 hrs and 7 days of freezing, respectively. Non-genetic factor(season) had only significant (p<0.05) effect on volume of ejaculate.
