Online published on 31 August, 2018. Abstract The study was carried out with eight apparently healthy male buffalo calves to see the effect of Saccharomyces cerevisae (Yea Sacc1026) supplementation on rumen microbial population and metabolites during summer season. The animals were divided into three groups of four each. Group I (Pre-summer), Group II (summer control) and Group III (summer treatment). Same animals were used in pre-summer and summer control Groups. The animals of Group III were supplemented with Yea Sacc1026 @ 1 bolus (consisting of 25 billion live yeast cells)/animal/d. There was significant (P<0.05) decrease in total bacterial count, total protozoal count, percent entodiniomorphs and A significant increase (P<0.05) in percentage of holotrichs during summer season. The microbial population was higher in Yea Sacc1026 supplemented group as compared to presummer and summer contol groups. However, following supplementation of Yea Sacc1026, there was no significant change in percentage of holotrichs and entodiniomorphs as compared to pre summer and summer control groups. During summer season, there was significant decrease in concentration of total volatile fatty acids and significant increase in levels of ammonia N and total N. The values of above parameters improved with yeast administration. Molar proportion of acetic acid and butyric acid was higher during summer season whereas proportion of propionic acid decreased and these values were restored to normal after Yea Sacc1026 supplementation but butyric acid did not show any change. Hence, supplementation with Yea Sacc1026 could be useful in improving rumen microbial population and optimizing the concentration of rumen metabolites thus ameliorating the adverse affects of summer stress on rumen profile in buffalo calves without affecting feed intake.
