MAIZE GRAIN AS FOOD 715 



677. Distillery Slop. — After the alcohol has been taken off, CHAP, 

 in the distilling of spirits, the residue is pressed to remove as XIV - 

 much of the remaining liquid matter as possible ; this is used 



by cattle feeders under the name of distillery slop. 



678. Brewers Grains. — Brewers' grains are a by-product 

 obtained in the brewing of beer ; they usually consist of a 

 mixture of several grains, varying according to the locality 

 where they are made ; commonly maize, barley, and rye. 

 Brewers' grains form an acceptable food for milch cows, where 

 large percentages of protein are required {Hunt, 1). 



679. " New Corn Product ." — Under this name a substance 

 has been sold for stock-food in the United States which is 

 composed of the husks, leaf-blades, and stalks (freed from the 

 pith) of the maize plant, ground into a coarse meal. Though 

 it contains a high percentage of indigestible matter (" crude 

 fibre"), the Maryland (U.S.A.) Station (Bull. 51) found it more 

 digestible than timothy hay, in place of which it was success- 

 fully used for feeding horses. The protein content is only 

 6 - 5 per cent, which is less than that of maize bran ; the ash is 

 high (5-4 percent); carbohydrates moderately high (49/3 per 

 cent). 



A somewhat similar product is made by mixing maize 

 leaves with the rough outer part of the stalk and other refuse 

 from the cellulose factories (see chap. XVII.), and grinding the 

 whole finely for stock-food. A by-product of the paper fac- 

 tories {ibid.) is also sold for stock-food ; experiments show 

 that the feeding value of this material is higher than that of 

 the original stalk containing the pith. 



Another stock- and poultry-food sold in the United States 

 is said to be prepared from the dry leaves, husks, and outside 

 of the maize stalk, mixed with ox blood, molasses, meals, and 

 chopped meat. 



680. Cerealine-feed. — This is a by-product obtained in the 

 manufacture of " cerealine " breakfast foods. The crude fibre 

 is low ; the protein, ash, and fat are moderate, and the carbo- 

 hydrates high ; it is almost identical with " hominy-feed ". 



68 1 . " Hominy-chop " and " Hominy-feed ". — These consist 

 of the hull, germ, and starchy refuse from the samp or hominy 

 factory, and differ from crushed maize in that a large portion 

 of the starchy endosperm has been removed, leaving a higher
