A study was undertaken to investigate the effect of supplementing different doses of yeast cultures (Saccharomyces cerevisiae) on milk production, milk composition and feed conversion efficiency. The experiment was conducted by using Randomized Block Design (RBD) with three treatments T0 -Without Saccharomyces cerevisae, T1 - (Saccharomyces cerevisae) @ 0g / day. T2 -Saccharomyces cerevisae @ 20g / day. The dietary supplementation of yeast cultures significantly (P<0.05) increased DMI when presented in kg/100 kg body weight and kg/whole milk. The average roughage intake was significantly higher (P<0.05) in T2 group as compared to T0 group. The average milk yield and fat yield were significantly (P<0.05) higher in T2 groups, as compared to T0 and T1 group. However, average fat per cent in milk did not differ significantly from each other. The feed conversion efficiency for dry matter (kg/kg whole milk) was 1.076±0.140, 1.118±0.153 and 1.172±0.175 in T0, T1 and T2 groups, respectively, which significantly (P<0.05) differed from each other. The average daily DCP intake and TDN intake in T0, T1 and T2 groups were similar. The daily feed cost was significantly (P<0.05) higher in T2 groups, as compared to T0 and T1 group. When the economics of milk production on supplementing yeast culture was calculated, it was observed that supplementing yeast cultures to crossbred cows resulted in increase in net daily income of Rs. 14.26 per cow, in T2 groups, as compared to control group (T0).
