title: Seasonal variation in freezability of buffalo semen.
abstract: Fifty-six buffalo semen ejaculates of mass activity greater than plus three on a five-point scale (28 each in summer and winter seasons) were frozen in Tris yolk glycerol (TY-G) extender with four hours equilibration time. Motility of semen was checked after first extension (initial motility), after equilibration time, 15 minutes after freezing, and 30 days after freezing. Motility increased during winter season. Significant differences (P<0.01) in motility after freezing were observed between summer and winter seasons.
