III. Protein 14 to 20 per cent. Wheat middlings, wheat bran, 

 wheat shorts, oat middlings, flax feed, rye feed, cotton seed, sun- 

 flower seed. 



IV. Protein 10 to 14 per cent. Rice bran, rice polish, ground 

 oats, ground wheat, barley meal, rye meal, hominy feed, oats 

 mixed with barley. 



V. Protein 8 to 10 per cent. Corn bran, corn meal, corn chops, 

 corn and oat feed, oat feed, dried beet pulp, beet molasses, kaffir 

 corn, milo maize, corn and cob meal, sorghum seed. 



VI. Protein less than 8 per cent. Cane molasses. 



Classes of Roughages. Roughages may be divided into the 

 following groups : 



I. Fodders. Corn fodder, corn husks, katfir stover, sorghum. 

 These contain from 3 to 12 per cent, protein and from 23 to 35 

 per cent, crude fiber. 



II. Cereal Straws. Oat, barley, rice, rye, and wheat straws, 

 containing 3 to 6 per cent, protein and 35 to 40 per cent, crude 

 fiber. 



III. Grass Hays. Bermuda, Johnson grass, timothy, millet, 

 etc., containing 5 to 15 per cent, protein, and 22 to 35 per cent, 

 crude fiber. 



IV. Legume Hays. Alfalfa, clover, cowpeas, peanuts, vetch, 

 etc., containing 12 to 20 per cent, protein and 20 to 28 per cent, 

 crude fiber. 



V. Waste Milling Products. Peanut hulls, corn cobs, cotton- 

 seed hulls, oat chaff, oat hulls, rice hulls, wheat chaff, etc., some- 

 times mixed with concentrated feeds, but properly classed with 

 roughage. They contain 2.5 to 5 per cent, protein and 30 to 48 

 per cent, crude fiber. 



VI. Fresh Grass or Fodder. Millet, oats, barley, sorghum, 

 timothy, etc., contain about 80 per cent, water and I to 4 per cent, 

 protein. 



VII. Fresh Legumes. Alfalfa, clover, cowpea, vetch, etc., 

 containing 70 to 85 per cent, water and 2.5 to 5 per cent protein. 



VIII. Silage. Corn, sorghum, clover, usually corn containing 

 70 to 85 per cent, water and I to 4 per cent, protein.
