 lasted twenty weeks, practically the entire fattening period. Fur-

 in the second experiment. 



LINSEED-MEAL (A PROTEIN CONCENTRATE) COMPARED WITH ALFALFA 



(A PROTEIN ROUGHAGE). 



The two experiments with protein concentrates conducted to 

 date favor the use of linseed-meal as a food supplementary to corn 

 when the roughness consists of either prairie hay or corn-stover. 

 The question now arises, would it be possible to supply sufficient 

 protein by making half of the roughness alfalfa, dispensing with 

 the use of the concentrates, and still be able to secure just as satis- 

 factory gains? This would make it possible to utilize a great deal 

 of stover or prairie hay, and at the same time obviate the neces- 

 sity of purchasing the commercial food. Two experiments in which 

 the ration corn and linseed-m.eal was compared with corn without 

 such a food when alfalfa forms half the roughness are here re- 

 ported.
