182. Wet brewers' grains. — These grains can only be fed in the 



vicinity of the brewery, o\nng to the large amount of water they 



carry. This fact has led to the extensive feeding of dairy cows 



in the proximity of breweries, which are generally located where 



there is a large demand for milk. Because a certain kind of city 



milk supply is often in the hands of ignorant people and is not 



' properly supervised by officials, the cows in some instances are 



crowded into dark sheds where the air is foul and the animals 



enjoy little or no exercise or sunshine. Because the wet grains 



are low priced and easily procured, the cows are wholly or almost 



entirely maintained upon them. The drippings from the wet 



grains pass downward through the feed boxes and under the 



floors of the stable, where fermentation takes place, giving rise to 



bad odors. Often, too, the grains accumulate in the stable an(? 



are not fed until they have become putrid. In view of all these 



; circumstances, it is not surprising that boards of health have 



I sometimes reached the conclusion that wet brewers' grains are not 



. a suitable feed for dairy cows under any circumstances, and have 



'prohibited the sale of roiilk from cows fed upon them. 



There is nothing whatever in wet brewers' grains which is 

 poisonous or deleterious in mUk production, provided they are 

 properly fed while fresh. The trouble arises from the great 

 abuse of a most excellent feeding material which is of such char- 

 acter that it can easily be abused. Supplied in reasonable 

 quantity while fresh, and fed in water-tight boxes which are 

 kept clean, with nutritious hay and other coarse pro-\'ender, 

 there is no better feed for dairy cows. So great and so frequent, 

 however, are the dangers from their abuse, that wet brewers' 

 grains should never be used for cows yielding milk for city 

 supply unless they are fed under the strict supervision of com- 

 petent officials. K this cannot be done, then perhaps it is best to 

 prohibit their use altogether. 



183. Dried brewers' grains. — By removing the excessive moist- 

 ure of the wet grains, through drying, a product is obtained 

 which is concentrated and no more perishable than bran. Dried 

 brewers' grains are riehjn i^rotein, lojwjn carbohydrates,and_rifiSj
