The present study was conducted to evaluate the effect of dietary supplementation of yeast (Saccharomyces cerevisiae) on haematological parameter in 21 Surti young female buffalo calves (aged 6-12 months). They were divided equally into 3 groups (7 calves in each group) viz. Group I (control), II (supplementation of rumen specific yeast Saccharomyces cerevisiae CNCM I-1077 @ 4x109 cfu/animal/day) and III (supplementation of product of inactivated whole cell yeast Saccharomyces cerevisiae containing elevated levels of L (+) selenomethionine @ selenium inclusion rate in feed at 0.3 ppm). Whole blood was collected at day 0, 45 and 90 and haematological parameters were studied. Except in Group II which showed significant decrease in TEC, all haematological parameters were found within normal physiological range. Thus it was concluded that in female Surti buffalo calves supplementation of yeast and selenized yeast did not cause any significant change in haematological parameters.
