Summary

Twenty-four Murrah buffalo cows were divided into 4 groups and were fed 0·3, 0·4, 0·5 or 0·6 kg of concentrate mixture per litre of milk produced. Energy and N balance studies were conducted on 2 animals from each group in the sixteenth and seventeenth weeks of the study. The efficiency of conversion of gross energy into milk energy ranged from 10·9 to 12·7%. The efficiency of conversion of metabolizable energy (ME) and ME above maintenance into milk energy ranged from 25·0 to 32·2% and from 51·7 to 78·6% respectively. Differences amongst groups were not significant for all the 3 parameters.

The conversion of digestible N into milk N varied between 23·6 and 27·3% in different groups. The efficiency of utilization of metabolizable N for milk production ranged between 47·6 and 56·4%. Various groups however did not differ significantly from each other in these respects.
