Feeds and Feeding. 



556. Roughages with cotton-seed meal. — During each of three 

 years, Duggar and Ward of the Alabama Station^ fed 4 lots each of 

 5 grade 2-yr.-old steers for 84 days on the rations averaged below: 



The table shows that the steers fed cotton-seed hulls for roughage 

 made larger and more economical gains than those fed either shredded 

 corn stover or cut sorghum hay. When corn-and-cob meal was sub- 

 stituted for one-third of the cotton-seed meal with steers fed cotton- 

 seed hulls for roughage, about the same returns were secured as with 

 cotton-seed meal alone. 



557. Legume hay w^ith cotton-seed meal. — Craig and IMarshall of 

 the Texas Station- fed 4 lots of 5 yearling steers each on cotton-seed 

 meal and rice bran with peanut, alfalfa, or cowpea hay or cotton- 

 seed hulls for roughage. After 6 weeks the steers getting peanut hay 

 developed looseness of the bowels and showed redness of the eyes and 

 some swelling about the sheath ; when changed to prairie hay the un- 

 favorable symptoms disappeared and the gains increased. (264) Al- 

 falfa hay fed with a large allowance of cotton-seed meal likewise pro- 

 duced scours, the steers gaining only 1.9 lbs. each daily. When 

 shelled corn replaced a part of the cotton-seed meal they gained 2.7 

 lbs. each daily. When fed with a large allowance of cotton-seed meal, 

 cowpea hay proved more satisfactory than either alfalfa or peanut 

 hay, tho slightly less valuable than cotton-seed hulls. (261) Peanut, 

 alfalfa, and cowpea hay, being rich in nitrogenous matter, serve their 

 best purpose when combined with carbohydrate-rich concentrates 

 such as corn, kafir, and milo. Where heavy nitrogenous cotton-seed
