trate mixture. It was found that the dried heet pulp is a highly digesti- 

 hle concentrate ingredient. As fed, it contained 4.24 per cent digestihle 

 protein, 70.93 per cent total digestihle nutrients and 78.3 therms net 

 energy per 100 lhs. The protein content of the dried heet pulp is in 

 the range of that of corn and it is well utilized. 



The results of the experiment' show that dried heet pulp is an ex- 

 cellent source of energy for dairy cattle when fed with hay or as part 

 of the concentrate mixture.
