114. Wide and narrow rations. At the Maine Station 1 Jordan 

 studied the influence of a ration rich in crude protein and of one 

 poor in crude protein on the rate of growth and character of the 

 flesh formed by growing steers. Four high-grade Shorthorn steer 

 calves, from 5 to 7 months old when the trial began, were used. 

 Two were fed a liberal ration rich in crude protein, while the 

 others received one equally ample in total nutrients, but poorer 

 in crude protein. One steer in each lot was slaughtered at the 

 end of 17 months and the remaining two at the end of 27 months, 

 all carcasses being analyzed to determine whether any difference 

 existed therein. The concentrates fed were as follows : 



Lot I. 

 Narrow ration 

 Linseed meal, 2 parts. 

 Corn meal, 1 part. 

 Wheat bran, 1 part. 



Nutritive ratio, 1:5.2. 



Lot II. 

 Wide ration 

 Corn meal, 2 parts. 

 Wheat bran, 1 part. 



Nutritive ratio, 1:9.7. 



The roughage, the same for all, consisted mostly of timothy hay, 

 some corn fodder and corn silage being fed during the first win- 

 ter only. It is seen that Lot I received a narrow ration, rich in 

 crude protein and mineral matter, while Lot II was fed a wide 

 ration with much less, tho sufficient, protein and mineral matter. 

 Both lots were liberally fed, tho there was no attempt to force 

 growth.
