The claim is not made here that protein is the only basis of value^ 

 but that a sufficient amount is essential to milk production, and that any 

 deficiency of this compound in the roughage must be supplied in the 

 grain. 



As there is' a limit to the grain a cow will consume, where roughage 

 having a low per cent of protein is used, highly cultivated grain must be 

 fed, which adds to the most of th e ration, as; is shown by the following 

 tables of balanced rations, made of corn silage and soja beans.

The above shows less colories of heat than is usually given in a 

 ration, but is sufficient for summer, and in winter can be supplemented 

 by warm brans and blankets at less cost than grain. 



As an answer to the claim that there is a great loss in ensilage, atten- 

 tion is here called to the loss in curing hay and fodder. (Bulletin No_
