Concentrate supplement containing 18-20% CP and 60-70% TDN was given to the animals based on their milk production at the ratio of 1:1 (kg of concentrate/kg milk) for treatment I, 1:1.5 for treatment II and 1:2 for treatment III. Rice straw-molasses-waste mixture (RSMW) was fed ad libitum. Animals under treatment IV which served as to control were given concentrate and Napier grass following the usual feeding management of Baturraden Breeding Center. Animals under treatment I consumed significantly (P0.05) more dry matter (19.01 kg/day) than those under treatment II (15.52 kg/day), treatment III (14.7 kg/day) and treatment IV (11.7 kg/day). Milk production of the animals under treatment I was the highest among the four treatments. However, daily milk production and 120-day record showed significantly different from those under treatment III. Income over feed cost of treatment I was found to be highest among the four treatments, but not significantly different from that of treatments II and IV. The results indicate that rice straw can be utilized as the sole roughage source for dairy cows provided 1 kg concentrate supplement (18-20% CP; 60-70% TDN) is given
