The following table taken from Bulletin No. 156 of Virginia, shows 

 the comparative value of gluten meal and cottonseed meal for milk 

 production : 



The authors conclude that the two feeds have nearly the same 

 value in milk production. 



Based upon the comparative percentage of digestible protein and 

 assuming clover to be worth $5 per ton, Smith** quotes alfalfa at $8; 

 cow pea hay at $8; wheat shorts at $9; wheat bran at $9; Canadian 

 peas at $12.50; cow peas at $13.60; skim milk at $2.10; soy beans at 

 $21.70; oil meal (old process) at $21.50; gluten meal at $19. When 

 the fats and carbohydrates are taken into consideration, assuming 

 clover to be worth $5 per ton, gluten meal is worth $23 a ton. 



Corn Bran. Corn bran differs from wheat bran in containing 

 more crude fiber and less protein. As a pure product when first put 

 out it found but little sale. The hulls, even when ground finely, have 

 very little flavor and are not palatable. 



Gluten Feed. In order to dispose of the corn bran and to 

 lighten the gluten meal, the two are now mixed and a product known 

 as gluten feed put on the market. By a close study of the foregoing 

 table, it will be noted that the content of protein is lowered about 

 5 per cent, while the percentage of crude fiber and ash is increased. 

 This change widens the nutritive ratio. 



According to tests made at the Nfew Jersey Station*, 100 pounds 

 of milk were produced for 86.40 cents with gluten feed, when fed in 

 conjunction with wheat bran, cottonseed meal, corn silage, and corn 

 stalks. 



Corn Oil Meal. — Corn Oil Cake. The residue remaining 

 after all but about 10 per cent of the oil has been extracted, is 

 known in the slab form as it comes from the press as "corn oil cake,"
