FEEDS AND FEEDING.

meal, 3 Ibs. wheat bran, 10 Ibs. red clover hay and 15 

 Ibs. corn stover. Let us figure this ration and find out 

 if it is properly balanced for the herd of dairy cows. 

 Turn to Table i and find that the following amounts 

 of digestible ingredients are present in 100 Ibs. of each 

 feed stuff.

Then as 5 Ibs. of cotton-seed meal are in the ration, 

 we multiply the amounts of dry matter, digestible pro- 

 tein, digestible carbohydrates, and digestible fat as 

 given above for cotton-seed meal, by 5. Or 5 x .918 

 = 4.590 Ibs. of dry matter in 5 Ibs. cotton-seed meal. 

 5 x .372 = i. 860 Ibs. digestible protein in 5 Ibs. cotton- 

 seed meal. 5 x .169 .845 Ibs. digestible carbo- 

 hydrates in 5 Ibs. cotton-seed meal. 5 x .122 = .610 

 Ibs. of digestible fat in 5 Ibs. of cotton-seed meal. In 

 the same way we compute the digestible ingredients in 

 the wheat bran, red clover hay and corn stover.

With the fat reduced to carbohydrates the ration 

 reads:

The ration is too high in dry matter, digestible pro- 

 tein and digestible carbohydrates. The ration is also 

 too narrow.
