"Sattig reports using dried brewers' grains and finding them a cheap winter feed for horses, the energy and general condition of the animals being pronounced as good as though they were maintained on oats. Trials in feeding the dried grains to street-car horses by the New Jersey Station gave satisfactory results, with the cost of the ration reduced several cents per day" (Henry). The ration in question was as follows : - Hay, 6 lb.; bran, 2 lb.; maize, 4 lb.; dried brewers' grains, 8 lb. We also learn from Henry's Feeds and Feeding, that the following low-priced ration has given good results in America with cart horses weighing from 1,100 to 1,200 lb. : Hay, 8 lb., maize meal, 6 1/2 lb., and dried brewers' grains, 6 1/2 lb.

In brewing, the starch which has been converted into soluble compounds by the process of malting and the sugar that is present in the grains are utilised for the manufacture of beer, while the nitrogenous matters remain unchanged. Consequently, these grains are rich in nitrogen. They also contain a large amount of phosphates, but are poor in potash, which deficiency is no drawback to their feeding value; because the percentage of potash in hay and other kinds of forage is in excess of the requirements of the horse. "While brewers'" grains dried by any open air process may be subject to criticism, the charge cannot stand for grains which are dried rapidly in partial vacuum" (Henry).

Owing to its high percentage of starch, maize would be a very useful addition to dried brewers' grains, which are particularly rich in nitrogen.
