Abstract: Twenty one postpartum Surti buffalo were selected and divided into 3 groups of 7 buffaloes each viz. group I (control), group II and group III. Diet of group II buffaloes was supplemented with rumen specific yeast Saccharomyces cerevisiae CNCM I-1077 @ 10x109 cfu/animal/day of group III was supplemented with selenized yeast-inactivated yeast Saccharomyces cerevisiae containing selenomethionine ensuring dietary inclusion of selenium @ 0.3 ppm.Dietary supplementation was done for 90 days from parturition. Rumen liquor (5 ml) was collected at day 0 (parturition), 45 and 90 day postpartum. Rumen liquor was analyzed for rumen parameters (pH, total volatile fatty acids concentration, concentration of ammonia-nitrogen, protozoal motility, enumeration of ruminal protozoa (Entodiniomorphs and holotrichs) and bacteria. Group II that was supplemented with rumen specific yeast showed significant increase in rumen pH, TVFA, protozoal motility and its count. Remaining rumen parameters in group II were better but non-significant as compared to other two groups. Selenized yeast supplementation in group III led to significantly higher levels of TVFA, protozoal count and entodiniomorphs and significant decrease in holotrichs during postpartum stages as compared to control group. Observations for remaining parameters mostly had levels between control (group I) and group II (rumen specific yeast supplemented group) however the differences were non-significant. Thus it was concluded from the present study that supplementation of rumen specific yeast (Saccharomyces cerevisiae CNCM I-1077) in the diet of postpartum Surti buffaloes for a period of 3 months after parturition favours production of beneficial fermentation metabolites in rumen and improves rumen microbial profile. It was also concluded that supplementation of rumen specific yeast in postpartum Surti buffaloes was more beneficial than selenized yeast.
