To study the effects of probiotics supplementation in lactating kankrej cows, a farm trial of 90 days was conducted in Kushkal village, Palanpur taluka of Banaskantha district of North Gujarat. The parameters studied were production performance and economics of feeding. Fourteen lactating Kankrej cows were divided in to two dietary treatments T1 (control) and T2 (probiotics). The results revealed that supplementing probiotics to lactating Kankrej cows significantly improved fat percent, 4% FCM while milk production and return as percent of feed cost were increased but remained statistically similar as compared to control.
