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

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-

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 Fig. 36,—Section of corn_ kernel. 
Indian corn, the main difference being Sra ere ay 
that it is higher in fat and lower in nitrogen-free extract than is 
Indian corn, and also somewhat higher in fiber, 4s will be seen

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
