66 THE FARM DAIRY. 



Calculating Feed Values. — When buying feed 



I figure about as follows : When com is worth 

 50 cents per bushel, it costs $18 per ton, which 

 contains 125 lbs. of protein and makes the pro- 

 tein cost 14 cents per pound. 



When wheat bran costs $16 per ton and con- 

 tains 250 lbs. of digestible protein, the cost per 

 pound of protein is 6.4 cents. 



When oats are worth 32 cents per bushel it is 

 equal, to $20 per ton which contains 182 lbs. of 

 digestible protein and makes the protein cost 



II cents per pound. 



With the Chicago cream gluten meal costing 

 $26 per ton and containing 644 lbs. of protein 

 (or 32.2 per cent) the protein costs 4.5 cents 

 per pound. 



Grano Gluten feed at $17.20 and containing 

 26 7/10 per cent protein, or 534 lbs. in a ton, 

 makes the protein cost 3.25 cents per pound. 



Ground oats are an excellent food for cows, 

 but many times they are bringing such a price 

 in the market that it makes it economical to sell 

 them and buy some of the feeds that are rich in 

 protein. To illustrate: a ton of oats, or 62i/^ 

 bushels, may sell at 28 cents per bushel and the 

 $17 received if invested in gluten meal at $28 

 per ton will buy 1,250 pounds of this feed, which 

 contains 32 per cent or more of protein. This 

 exchange of oats for gluten feed gives 400 

 pounds of protein in place of the 182 pounds
