acid content). The hulls (skin) contain very nearly one-half of 

 the total fiber, and the starchy part about 90 per cent of the total 

 nitrogen-free extract of the kernel. 



The only by-products of corn or hominy mills used for feeding 

 farm animals are corn bran and hominy meal. Both of these are 

 obtained by similar manufacturing processes as those given under 

 wheat feeds. The corn bran does not differ greatly from wheat 

 bran in chemical composition; it is lower in ash and protein, and 

 somewhat higher in carbohydrates and fiber, however; its digesti- 

 bility is slightly higher than that of wheat bran, except for the 

 protein it contains, which is consider- 

 ably lower, viz., 54 per cent, against 

 77 per cent for wheat bran. The two 

 feeds may, in general, be considered 

 of similar feeding value, in so far as 

 it is possible to compare the feeding 

 values of two feeds of as different nu- 

 tritive ratios. 



Hominy meal, feed or chop, con- 

 sists of the bran ? germ, and soft floury 

 portion of the kernel which are sepa- 

 rated in the process of making hominy 

 grits for human consumption. It 

 forms a very valuable, palatable, fat- 

 tening feed, of a similar composition to 

 Indian corn, the main difference being 

 that it is higher in fat and lower in nitrogen-free extract than is 

 Indian corn, and also somewhat higher in fiber, as will be seen 

 from the following average analyses :

Hominy meal is a highly valued feed for milch cows and fatten- 

 ing steers, and may serve a useful purpose as a substitute for Indian 

 corn in rations for these and other farm animals. Like all corn
