Effect of dietary oilseed supplement on nutrient utilization, milk yield and composition of lactating buffaloes [electronic resource].

Includes references.

Two groups, each offive multiparous lactating buffaloes were arranged into two swing over experiments. Crushed full fat cottonseed or canoia seeds was used to replace 25% and 50% of energy of concentrate mixture which contained 55% starch value and 14% crude protein. Fat content afthe experimentaL rations averaged 3.4, 4.5% and 6.3% for control, low and high oilseed levels, respectively. Nutrient requirements were individually calculated based on milk yield and live body weight. Nutrient digestibilities were significantly decreased exrcept ether extract, which showed .significant increase for high fat diets. Milk yield and 4%-fat corrected milk yield (FCM) increased, especially for buffaloes fed high cottonseed diet. Milk fat percentage was not significantly affected by dietary low fat inclusion, however, it was significantly increased in high cottonseed containing diet. Milk protein percentage decreased }Fhen high fat diets were fed. Milk total solids, lactose and solids not fat were not significantly affected b.v oilseed inclusion.
