Abstract :

India is the highest milk producer in the world, contributing about 17% of the world production. The annual growth rate in this sector is 4% which is nearly three times that of world. As the agricultural lands are far decreasing and the human population is far increasing, our aim to improve milk output should be by way of improving productivity of animals rather than increasing the heads of bovine population. The pricing of milk throughout India is based on the fat and SNF content. During early lactation there will be a drop in both of these parameters as the production is increasing. In a state like Kerala where there is scarcity of roughage, alternative sources to address the low milk fat syndrome during early lactation are the need of the day. A study was conducted to evaluate the effect of bypass fat supplementation on milk constituents in crossbred cows in early lactation. 18 early lactating crossbred cows were selected and divided into 3 groups of 6 each. Animals in group T2 and T3 were supplemented with 200 gm. and 400 gm. bypass fat respectively for 45days.The milk fat and total solid per cent in animals supplemented with 400 g of bypass fat (T3) was higher than T2 and T1 at the end of the experiment, but the milk protein per cent was lower in both supplemented group compared to T1. Keywords: early lactation, milk fat, milk protein, bypass fat, energy
