1. From all considerations, semen obtained during spring was found to be best while that obtained during summer was at its worst. It improved considerably with the onset of the rainy season. 2. Autunn was conspicuous by being as inferior as summer in certain respects. Although live spermatozoa was as high as 91% during the autumn, effect of cold shock treatment revealed that many of the spermatozoa were not resistant to it indicating their fragile natureza. Incindentally, the per cent decline in initial mortility following in vitro storage was also highest during autumn. The observation that buffalo semen obtained during autumn cannot be stored well after dilution in vitro appears to be closely linked with the behaviour of the autumn spermatozoa to cold shock treatment. 3. Fructolysis/live sperm did not vary significantly between seasons but O2 consumptions did. The later attribute appeared to reflect correctly the influence of season on the metabolic behaviour of spermatozoa. 4. There was a higly significant inverse correlation between sperm concentration/ml. and initial fructose content. 5. The estimates of initial motility was found to posses a highly significnt correlation with concentration of live spermatozoa, per cent survival following cold shock, oxygen consumption, fructolysis and "half-life" stortage.
6. Incidence of live spermatozoa was positively correlated with consumption and "half-life" storage. 7. The resistance to cold shock was also significantly correlated with fructolysis, O2 uptake and potentiality of storage in vitro. 8. The multiple regressions of the various semainal attributes on the climatic elements have been worked out. It was revealed that temperature was by far the most important of the three climatic variates. It was also evident from the study that altough three variates were considered in determining their relationships with the seminal attributes, the multiple correlation coefficient values were not very high. They were only significant at 5% level in case of live sperm concentration before and after cold shock treatment and O2 uptake pattern of the spermatozoa, whereas in the remaining cases no significant relationship could be established. Reasons for such findings have been discussed. 9. The need for complete reorientation of the management practices of buffalo bulls to help obtain best quality semen during the breeding season of the buffalo cows in order to put the A.I. programme on a sound basis has been discussed.
