78 EXPERIMENT STATION. [Jan. 



Each of the two feedsturts contains substantially the same 

 amounts of digestible nutrients. The net energy values ex- 

 pressed in therms are as follows: brewers' dried grains, 50; 

 wheat bran, 40 ; or the brewers' grains are worth 10 per cent, 

 more than the bran. 



An experiment conducted at this station with 6 dairy cows, 

 in which brewers' grains were compared with wheat bran, led 

 to the following conclusions : — 



1. The brewers' grains ration produced slightly more live 

 weight, milk and milk ingredients than did the bran ration. 



2. Brewers' grains did not show any objectionable effect 

 either on the general condition of the animal or on the flavor 

 and keeping quality of the milk. They are nearly as bulky as 

 bran, and serve as a distributor of the heavy concentrates. 



(d) The Use of Brewers' Grains. 



Only those grains that have a light color and are free from 

 rancidity or sour taste and smell should be used. Grains that 

 have stood for any length of time before drying have fermented, 

 and are not satisfactory as a food. 



For Horses. — Brewers' dried grains serve excellently as a 

 partial oat substitute for horses, 2 pounds of the grains being 

 equivalent to 21/2 pounds of oats.^ Voorhees - states that brew- 

 ers' dried grains are a wholesome, nutritious and palatable horse 

 feed. He recommends for work horses, on the basis of 1,000 

 pounds live weight, 2 pounds bran, 4 pounds corn, S^/o pounds 

 brewers' gi'ains and 6 pounds hay. Very satisfactory results 

 are reported when hard-worked team horses received a daily 

 ration of brewers' dried grains and hay.^ The total amount 

 of dried grains to be fed daily will naturally depend upon the 

 size of the animal and the amount and character of the work 

 performed. From 3 to 8 pounds may be considered satisfactory, 

 the balance of the grain to consist of corn and oats, or corn and 

 wheat bran. 



For Pir/s. — Because of their deficiency in ash and starch, 

 and of the excess of hulls, the dried grains are not to be partic-
