I.— CLASSIFICATION OF THE CONCENTRATED FEEDS. 



Table II. 



Division I. 



Medium to high in protein. Medium in 



carbohydrates. 



la to 85 per cent digestible. 



Division II. 



Loic in protein. High in carbohydrates. 

 To to 85 per cent digestible. 



Cotton and linseed meals, gluten meal, pea 

 atid bean meals, peanut meal, gluten feeds, 

 corn oil cuke. Atlas meal, Chicago maize 

 feed. Hall's dairy feed, dried brewers' 

 ^rain, malt sprouts,* bran and middlings,* 

 Buston and Quincy mixed feeds.* 



Wheat, oats, barley, rye, Indian corn, corn 

 and cob meal, corn-germ feed, hominy feed 

 orchop, cerealine feed, rice meal, oat feeds.* 



Below 12 per cent may be termed low protein, from 12 to 

 23 per cent medium protein, and above 23 per cent high 

 protein. Below 50 per cent may be termed low carbohy- 

 drates, l)etween 50 and 60 medium, and from 60 to 75 per 

 cent high carbohydrates. All of the feeds in Division I. 

 have a narrow nutritive ratio (1:2 to 1:5), and those in 

 Division II. a wide ratio (1 : 8 to 1 : 10). 



II. — PREPARATION, COMPOSITION AND DIGESTI- 

 BILITY OF CONCENTRATED FEEDS. 



Division I. 



Cotton-seed 2Iecd. — The seeds of the cotton plant are 

 black in color, irregular egg-shaped in form, and almost 

 hidden by a tuft of white fibre which covers their surface. 

 The meat of the seed is covered with a thick, tough hull. 

 Machines have been invented to remove this hull, and the 

 meat is subjected to warm pressure which removes the 

 greater part of the oil. The pressed cake is ground, 

 and results in the decorticated, bright yellow cotton-seed 

 meal of commerce. Sometimes a considerable portion of 

 the hull is ground with the meat, making a dark meal of 

 inferior feeding value. 



Linseed Meals. — The seeds of the flax are flattened 

 elliptical oval, pointed at the lower end, and of a brown
