Abstract: Data on 675 ejaculates collected from four Malabari bucks spread over six years were utilized to assess the influence of genetic and non-genetic factors on semen quality traits. The overall least-squares means for semen volume, mass activity, initial sperm motility, pre-freeze motility, post-thaw motility and number of frozen semen doses per ejaculate were 0.81 ± 0.01 ml, 4.80 ± 0.02, 79.60 ± 0.00 per cent, 76.31 ± 0.00 per cent, 35.16 ± 0.00 per cent and 27.16 ± 0.59 doses respectively. The genetic and non-genetic factors had significant influence (p<0.05) on pre-freeze and post-thaw motility, while season and buck had highly significant influences (p<0.01) on semen volume, initial sperm motility and number of doses per ejaculate. Bucks had highly significant influence (p<0.01) on mass activity. Winter season had highest semen volume, post-thaw motility and number of doses per ejaculate, whereas initial sperm motility and pre-freeze motility were higher in summer and south-west monsoon seasons respectively. The second ejaculate had higher prefreeze and post-thaw motility than the first ejaculate. Buck No. 3 was found to be best among the bucks in terms of mass activity, initial sperm motility, post-thaw motility and number of doses per ejaculate.
