BARLEY. 133 



pounds of oil-cake contain one of albumen or other proteine compounds, and costs 5d. 

 This ingredient of the food, therefore, is cheaper in the form of oil-cake than in that of 

 brewers' draff. 



d. Again, the quantity of ash left by the dry draff is about five per cent. One hundred 

 pounds in the wet state contain 0.6 lbs. of phosphates ; or 160 lbs., costing Is., contain 1 

 lb. of phosphates. But 33 lbs. of oil-cake contain 1 lb. of phosphates at a cost of nearly 

 3s. ; thus the phosphates are cheaper in the form of draff. 



Hence a mixture of other food, such as oil-cake or beans, along with it, is recommended 

 where the draff is to be used most economically and with least waste. 



e. A part of the feeding value found in the draff by past experience, is probably to be 

 ascribed to the steeping it has undergone, rendering the otherwise innutritive or slowly 

 nutritious matter soluble in the stomach, and thus admitting of less waste. 



Turnips are the kind of food most usually given with brewers' grains. The following 

 letter from Mr. Caird, Baldoon, near Wigton, shows the profit of feeding milk-cows upon 

 draff and turnips, compared with beans and turnips, according to his experience. 



" I have fed for the last two winters a large dairy stock in the following manner, for 

 between 6 and 7 months, or 200 days : 



Each cow half a bushel of draff (23 lbs.) per day, for 200 days, 100 



bushels at 3d. £ 1 5 



Each cow (22' lbs. per day), 2 tons of turnips, at 10s. - - - 10 



£2 5 



" And the dairyman to whom my cows are let prefers this feeding to the following, 

 which is the usual allowance in this district to a dairy stock : 



Each cow 4 tons of turnips at 10s. - - - - .- £200 



" 2 bushels of beans, ground, at 4s. 6d. - - - - 9 



£2 9 



In both cases the same fodder is given. 



" On the draff and turnips the cows give fully more milk and butter, both of which are 

 well tasted, and they keep themselves in better condition than when fed on turnips alone. 

 With this feeding they are a very healthy stock. 



" On the turnips and beans, the butter and milk are always strong tasted, and the cows 

 are not kept in such high condition as on the draff and turnips. 



" If cows get an unlimited supply of turnips, they may yield more milk than on the 

 quantity of draff and turnips mentioned above. They do not eat beyond a certain quantity 

 of draff, while it is difficult to satisfy their appetite for turnips. 



" The question as to which of the two is the cheapest food, depends altogether on the 

 respective money values of draff and turnips in any given locality."
