Abstract
Eighteen Mehsani buffaloes in their 2nd and 3rd lactation were selected to conduct on-farm trial at the Jalat and Borkheda villages of Dahod district for 150 days duration. The animals were selected on the basis of their average daily milk yield of last lactation, present daily milk yield, fat % and body weight. The experiment was initiated on 5th day of lactation. The experimental animals were randomly allotted to three dietary treatments i.e. T1 (Control) and T2 (Bypass protein) and T3 group (Bypass protein and bypass fat). There were six animals in each group. The experiment was conducted following Completely Randomized Design. All the experimental buffaloes were individually offered a basal diet of green shedha grass (5 kg) and wheat straw ad lib along with required amount of concentrate mixtures to meet their protein and energy needs for maintenance arid for milk production as per NRC (2001). The CP requirement of control group buffaloes was worked out and was supplied through 1.5 kg cotton seed cake; 1.5 kg gram chuni and the remaining from Type n compound concentrate mixture as per ISI (1979) Specification. The UDP requirement of treatment groups' (T2 and T3) buffaloes was worked out and was supplied through 1 kg formaldehyde (HCHO) treated guar meal and 2 kg cotton seed cake. The remaining quantity of CP required in treatment groups was supplied through gam chuni (up to 1.5 kg) and from compound concentrate mixture, so as to make the control and treatment ration isonitrogenous and isocaloric. The commercial bypass fat supplement, Megalac was provided to buffaloes in T3 group @ lOg/kg milk yield as per the recommendation of the manufacturer M/s. Vetcare India Ltd., Bangalore.
