The amount of total digestible nutrients fed daily in each ration 

 was practically the same during both periods. The brewers' grain 

 ration contained rather more protein and a little less carbohydrate 

 material than did the bran ration. 



HERD GAIN IX LIVE WEIGHT. 



Character of Ration. Pounds. 



Brewers" grains no. 



Wheat bran 6i.

 the difference was not marked. 



HERD YIELD OF MILK AND MILK INGREDIENTS. 



{Founds). 



The brewers' grain ration produced a slightly larger yield of milk 

 (3 %) and milk ingredients (i to 2 %) than did the bran ration, but 

 the difference was not much more than would be allowed for a 

 reasonable e.xperimental error. 



AVERAGE COMPOSITION OF THE HERD MILK. 



The average composition of the milk produced during both periods 

 was quite similar. While the brewers' grain ration produced 

 slightly more milk, it was a trifle more dilute than that produced by 

 the bran ration. The difTerence, however, has no significance.
