may be given up to 6 Ibs. per head per day, either 

 moistened or scalded. 



In the same manner and quantities they are 

 given to draught oxen and fattening bullocks,

 in the coombs, may cause these disturbances of

Brewers grains are the waste products left

 material, such as maize, rice, potatoes, etc. They 

 can be fed either fresh or dried, and amongst the 

 latter the lighter, less strongly heated, and there-

 and useful food, but they easily become sour and
