Abstract—Twenty four HFxDeoni cross bred cows were divided into four groups (6 cows in each group) on the basis of average milk yield, parity and stage of lactation. T0 (control group) cows were not fed with probiotics. T1, T2 and T3 (treatment groups) cows were fed with 10 gm, 15 gm and 20 gm probiotics per day, respectively, just before morning milking. The multi strain probiotic contained Saccharomyces cervisiae and Lactobacillus sporogenes. The animals were milked twice in a day; morning at 5.30 am and afternoon 3.30 pm. Daily milk yield was recorded in pre-trial period of 25 days and then during 60 days of experimental period. Milk samples from the individual cows were collected twice a week (in pre-trial period and in experimental period) and were analysed for fat, SNF, density, freezing point, protein, lactose and total ash using the milk analyzer. From pre-trial period to trial period, the milk yield increased from 8.31 L/day, 8.26 L/day and 8.48 L/day to 8.97L/day, 9.64L/day and 9.68L/day in T1, T2 and T3 group (highly significant; P<0.05), respectively, compared to from 8.45 L/day to 8.57L/day in T0 group. Milk were significantly higher in cows (T1, T2 and T3) supplemented with probiotics than T0. The freezing point decreased in T1, T2 and T3 groups indicating increase in the total solids of milk compared to T0. There were minor changes in ash content of milk by feeding probiotics. Economically, supplementing the diet with probiotic earned more profit and feeding @ 15 gm probiotic/day/animal was found more beneficial than feeding @ 10 and 20 g/day/cow.
