FORTY-SECOND ANNUAL CONVENTION 245 



tein to increase the palatability ,and improve the physiological 

 effect. It is very heavy, so that it is well to feed it in connec- 

 tion with a bulky feed. It is especially applicable in a mixture 

 to be fed with dry roughage. 



Cottonseed Meal (Choice). 



Digestible nutrients' — Protein, 37 per cent; carbohydrates and fat, 

 41.2 per cent. 



Cottonseed meal is the richest in protein of all the com- 

 mon cow feeds on the market. It is usually the cheapest source 

 of protein available, but it does not have the best physiological 

 effect upon the cow, often causing digestive troubles if fed in 

 large quantities for long periods. At first it is advisable to start 

 with I to 2 pounds a day, gradually increasing the quantity if nc 

 bad results are observed. In some herds in the North as high 

 as 5 to 6 pounds a day are fed without bad results. In the. South 

 there seems to be no limit in this direction. 



Cottonseed meal is a highly concentrated feed and should, 

 if possible, be fed in a mixture with some bulky feed like bran. 

 It can be fed to better advantage when the roughage contains 

 an ample quantity of succulent feed. While its physiological ef- 

 fect in the North at least is not good as compared with most 

 other cow feeds, its cheapness and the fact that in time the cows 

 seem to overcome this tendency to digestive trouble from it are 

 rapidly giving it great prominence as a cheap source of protein 

 for dairy cows. 



Gluten Meal and Gluten Feed. 



Digestible nutrients — Gluten meal: Protein, 30.2 per cent; carbo- 

 hydrates and fat, 53.8 per cent. Gluten feed: Protein, 21.6 per cent; 

 carbohydrates and fat, 59.1 per cent. 



Gluten meal is a by-product of the manufacture of starch 

 from corn. The basis of the meal is the germ part of the corn 

 kernel. Gluten feed is composed of the gluten meal plus a cer^ 

 tain quantity of corn bran, which makes it lighter than the meal. 

 Both feeds are fairly palatable and are usually among the cheap- 

 est source of protein.
