I, — CLASSIFICATION OF THE CONCENTRATED FEEDS. 

 Table II. 



Division I. 



Division II. 



Medium to high in protein. Medium in car- 

 bohydrates. 

 75 to 85 per cent digestible. 



LoiD in protein. High in carbohydrates. 

 75 to 85 per cent digestible. 



Cotton and linseed meals, gluten meal, pea 

 and bean meals, peanut meal, gluten feeds, 

 corn oil cake. Atlas meal, Chicago maize 

 feed. Hall's dairy feed, dried brewers* 

 grain, malt eprouts,* bran and middlings,* 

 Boston and Quincy mixed feeds.* 



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

 and cob meal, corn-germ feed, hominy feed 

 or chop, 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 carbohydrates, between 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 DIGESTIBILITY OF 

 CONCENTRATED FEEDS. 



Division I. 



Cotton-seed 3feal. — The seeds of the cotton plant are black in 

 color, irregular egg-sliaped in form, and almost hidden by a tuft 

 of white fiber 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 eliptical 

 oval, pointed at the lower end, and of a brown color. The seed 

 in its natural state contains 30 to 35 per cent of oil. Twenty to 

 28 per cent of the oil of the seed can be removed by warm pres- 

 sure. The pressed cake, dried and ground, furnishes the old proc- 

 ess linseed meal. Some factories secure a more thorough removal 

 of the oil by the use of naphtha or other solvent. The naphtha is 

 removed by steam, and the dried material furnishes what has been 



* From 60 to 70 per cent digestible.
