Sixteen crossbred lactating cattle of average 411.75±14.23kg body weight, 14.01±1.38 milk yield and 30.87±6.10 DIM were divided into four treatment groups of four animals each on the basis of milk yield and parity following completely randomized design. All the experimental animals were fed weighed quantities of wheat straw, green fodder and concentrate mixture to meet out the requirements as per feeding standards (NRC, 2001). The concentrate mixture of lactating cattle of treatment groups T2, T3 and T4, the CP of GNC of control group was replaced with CP of DDGS @ 50, 75, and 100 %, respectively. For cattle fed 50 and 100% DDGS in place of groundnut cake CP intake increased (P<0.05) as compared to the cattle fed control diets containing no DDGS. No significant difference among control and treatment groups revealed that concentrate mixtures having either groundnut cake or DDGS were equally accepted by the experimental cattle. Nutrient digestibility and dry matter, DCP & TDN intake in lactating cattle are not affected by replacing 50% groundnut cake with DDGS in their concentrate mixture. Nutritive value in terms of DCP & TDN percent of the ration fed to cattle and feed efficiency & feed conversion ratio are not affected at 50% substitution level. Milk yield, its composition and energy value of milk in crossbred cattle are not impacted due to substituting 50 % ground nut cake with distiller’s dried grains with soluble as primary protein source in their concentrate mixture, however,4% FCM yield augmented. There was net saving of Rs. 1.32 for feed cost per kg FCM production in cattle by feeding 50% DDGS, as protein source in place of ground nut cake.
