Feeds and Feeding, 



days on pasture, tested the value of a limited allowance of cotton- 

 seed meal as a partial substitute for corn. 



Cotton-seed meal as a supplement to corn for steers on pasture. 



It is shown that the substitution of 0.9 Ib. of cotton-seed meal for 

 an equal weight of corn increased the daily gain by 0.2 Ib., and ef- 

 fected a saving of 21 per ct. in the concentrates required for 100 Ibs. 

 of gain. 



At the Mississippi Station 1 MacLean fed 20 thousand-lb., poor-qual- 

 ity grade steers cotton-seed meal mixed with an equal weight of cot- 

 ton-seed hulls for 97 days in summer while grazing on mixed pasture. 

 The steers made an average daily gain of 1.3 Ibs., requiring 326 Ibs. 

 of cotton-seed meal and 328 Ibs. of hulls for 100 Ibs. of gain. These 

 steers fed on pasture made more economical gains and returned a 

 much greater profit than did a similar lot fed cotton-seed meal and 

 hulls during the winter. 



538. Linseed oil meal. Smith of the Nebraska Station, 2 as a re- 

 sult of 3 trials with steers fed corn and prairie hay in comparison 

 with others fed 90 per ct. corn and 10 per ct. linseed meal with 

 prairie hay, found that it required 23 per ct. less concentrates for 

 100 Ibs. gain when the ration containing linseed oil meal was used. 

 For steer fattening linseed meal was rated a little higher than cotton- 

 seed meal and much more valuable than wheat bran for supplement- 

 ing corn fed with prairie hay or corn stover. Smith found that 

 alfalfa hay furnished sufficient protein, and proved much cheaper 

 than linseed oil meal with fattening steers, yet no form of hay can 

 quite take its place in giving finish to such steers. (200) 



539. Linseed meal, corn, and pasture. At the Nebraska Station 

 Burnett and Smith pastured 2 lots, each of five 2-yr.-old steers, one 

 receiving 17.8 Ibs. corn meal per head daily and the other 16 Ibs. corn 

 meal and 1.8 Ibs. linseed meal. The steers getting the linseed meal 

 each gained 0.4 Ib. more daily, consumed 200 Ibs. less concentrates
