In the present study 24 high milk yielding crossbred cows were selected based upon their parity, lactation milk yield and body condition score. These cows were divided into four groups keeping 6 cows in each group. Cows in Group 1 and group 2 were fed with ration containing high NEL having and designated as high energy control (HEC) and high energy choline (HECh). Cows in Group 3 and Group 4 were fed with ration containing low NEL having and designated as low energy control (LEC) and low energy choline (LECh). Cows of HECh and LECh were supplemented with Rumen Protected Choline (RPC) at the rate of 30 g/day. The feeding of the cows was started 21 days before expected date of calving and continued upto 10 days post calving. Body weight and BCS were recorded up to 90 days post calving. Significant difference for average DMI was found between low and high energy groups during pre calving period and average DMI was significantly lower for cows fed on low energy ration. | Effect of prepartum rumen protected choline supplementation on postpartum nutrient intake, digestibility and body weight changes in crossbred dairy cows
