The lot of distillers' grains used was especially high in protein, 

 containing some 8j4 per cent more than the Buffalo gluten. This 

 increase was largely equalized by the higher digestibility of the 

 protein in the latter feed. The Buffalo gluten feed also contained 

 more digestible starchy matter. The calculated amount of total 

 digestible nutrients in the daily ration was nearly the same in each 

 case. These rations may be considered a trifle narrow.

It is evident that the cows received rather more food than was 

 necessary for a normal milk yield, which resulted in a slight increase 

 in weight. Though the gain was larger in the distillers' grains 

 period, the difference may be considered of minor importance.

The amount of milk and butter produced was slightly in favor of 

 the distillers' grains ration (4 to 6 per cent), but the difference was 

 not at all excessive.
