Also three rations where molasses contributed 25, 55 and 90 per cent of the cow's energetic requirements for maintenance and production. Rice straw represented 83.48, 69.12 and 58.89% of ration consumption/animal/day in treatments A, B and C, respectively. The average milk production/cow/day, was 6.0, 5.4 and 6.6 liters for groups 1, 2 and 3, respectively. Indistinctively of treatment to which animals were submitted. In period 1, group 1, energetic contribution after rations were below the requirements for the milk produced. During period 1 and 4 of group 3, there was an excess of energy. In all cases there was a 28% of protein more than required.
