Repeatability was estimated for volume, initial freezing motility per cent at 0 hr of freezing, post-thaw motility per cent after 0 hr, 1 hr and 2 hrs of incubation at 37°C, live per cent (non-eosinophilic) spermatozoa count, per cent head abnormalities and acrosomal integrity of stored frozen Murrah buffalo spermatozoa. The estimates were 0.202±0.089, 0.383±0.107, 0.104±0.084, 0.135±0.090, 0.142±0.092, 0.1l5±0.088, 0.402±0.100 and 0.155±0.090, respectively. The estimates were moderate to high for motility at 0 hr of freezing and per cent head abnormalities indicating that sufficient variation existed between different bulls which could be attributed to genetic and permanent causes and also suggesting an important role of these characteristics in screening of bulls.
