This study was carried out to determine the effect of yeast addition on dry matter intake, milk yield, milk composition and somatic cell count in Anatolian water buffalo diets. 10 buffaloes (genus: Bubalis, species: Bubalis bubalis) were randomly divided into two groups (five animals each), with 21 days of adaptation period and 7 days of the experimental period comprised the sampling period. SC-treated groups (n = 5 buffalo/group) received 30.0 g of SC per buffalo per day. Compared to the control group, the SC-treated group consumed more total dry matter (P<0.05; 14.27 vs. 13.50 kg/day) and produced more milk/day (P<0.01; 7.13 vs. 6.22 kg/day). Dietary yeast inclusion significantly increased alfalfa dry matter intake during a 28-day lactation period (P<0.01; 10.41 vs. 9.81 kg/day) compared with the control diet. Yeast application significantly reduced the somatic cell count (SCC) in milk (P<0.05; 3.33 and 1.08 SCC (log 10/ml) for control and SC-treated groups, respectively). The compositions of milk fat (58.40 and 59.00 g/kg), non-fat solids (120.00 and 122.80 g/kg), protein (46.40 and 46.26. g/kg) and lactose (37.72 and 38.90 g/kg) were similar for both groups. In conclusion it has been thought that farmers with Anatolian water buffalo can benefit from the use of yeast cultures in early lactation diets, which may improve efficiency and provide economic advantages.
