158 VARIETIES OF FOOD. 



Much of the barley imported contains a large percentage of 

 dirt, and it is manifestly absurd to expect the same result 

 from feeding with an equal weight of barley mixed with dirt 

 as with clean oats. In one marked case in connection with a 

 large stud in which barley has recently been condemned as 

 horse food, the real mistake, I believe, was in giving dirty 

 barley, and the condemnation should have been confined to- 

 the dirt, and not extended to the barley." 



My readers will consult with advantage Mr. Shaw's re- 

 marks on barley, page 180. 



DRIED BREWERS' GRAINS. 



"Sattig reports using dried brewers' grains and finding them 

 a cheap winter feed for horses, the energy and general con- 

 dition 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 Ib. ; bran, 2 Ib. ; maize, 4 Ib. ; dried 

 brewers' grains, 8 Ib. 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 Ib. : Hay, 8 Ib., maize meal, 6^4 Ib., and dried brewers* 

 grains, 6% Ib. 



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. Conse- 

 quently, 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"
