Supplementation Effect of Bypass Fat on Production Performance of Lactating Crossbred Cows

An on farm trial was conducted on 20 lactating crossbred cows randomly divided into two groups on the basis of milk yield (10 to 13 kg/d) and day of calving less than 60 d to note the effect of supplementing bypass fat on milk yield and fat percentage for a period of three years (2012 to 2015). Cross bred cows were fed concentrate, green and dry fodder and wheat straw in control group and addition of 100 g of bypass fat was given in treatment group. Experimental feeding was continued up to 90 d. The average milk production and fat percentage was significantly higher in treatment group. Milk production efficiency was also significantly higher in bypass fat supplemented group in comparison to control group. It was, thus concluded that bypass fat supplementation @ 100 g per day per animal in cows significantly increased the milk production and fat percentage over the control group.
