Four groups of 3 Surti buffaloes were given the following diets in a Latin-square design experiment as described previously [see Egyptian Journal of Dairy Science (1989) 17 (1) 137]: (i) low-protein concentrate mixture; (ii) as (i) plus thyroprotein; (iii) high-protein concentrate mixture; and (iv) as (iii) plus thyroprotein. Mean yield and composition of milk from cows given (i) to (iv) resp. was as follows: yield, 3.8, 3.4, 3.0 and 2.7 kg/day; fat, 7.1, 7.5, 6.8 and 7.5%; TS, 17.78, 17.94, 17.08 and 17.25%. Results showed that feeding a low-protein diet tended to increase milk yield and thyroprotein supplementation tended to increase milk fat; none of the treatments had an adverse effect on body wt. No significant differences were observed between treatments for digestibility coeff. of the diet, DCP intake or N, P and Ca balances.
