weeks, practically the entire fattening period. Furthermore, 

 grade Shorthorns were used in the first experiment and grade 

 Angus in the second. 



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 concentrate, and still 

 be able to secure just as satisfactory gains? This would 

 make it possible to utilize a great deal of stover or prairie 

 hay and at the same time obviate the necessity of purchasing 

 the commercial food. Two experiments in which the ration 

 corn and linseed-meal was compared with corn without such 

 a food when alfalfa forms half the roughness are here 

 reported.
