Twelve early lactating crossbred cows were divided into two equal groups viz., Groups T0 (Control) and T1 (Treatment). The groupT0 received farm made concentrate mixture whereas groups T1 received concentrate mixture containing 1% slow release non-protein nitrogen compound (SRNPN). Concentrate mixtures in both the experimental groups were made iso-nitrogenous. The experimental groups received paragrass and paddy straw as a source of roughage and experiment lasted for 180 days. The average dry matter, TDN and DCP intake, milk yield and 4% FCM yield of cows from group T1 was significantly (P≤0.01) higher than that of the group T0. The average DM, TDN and DCP required per kg FCM was comparable between both the experimental groups. The average specific gravity, solid not fat, total solids and total ash percentage of milk revealed non-significant effect of feed treatments, however, the average milk fat and protein percentage of cows from groups T1 was significantly (P≤0.01) higher than the control group. The digestibility coefficients for all the nutrients were significantly higher for SR-NPN supplemented feeds. The economics of the milk production revealed that the profit realized per day over feed cost per cow from in groups T0 and T1 was Rs. 91.51 and 105.61, respectively. Thus, it can be inferred that efficient utilization of poor quality roughages, better productivity and profit margin in lactating cows can be achieved by inclusion of SR-NPN at 1 percent level in the concentrate mixture of lactating cows.
