Value of Various Feeding Stuffs for Swine.

871. Linseed oil meal.— Forbes of the Missouri Station^ fed 6 lots, 

 each of 5 pigs averaging 93 lbs., for 90 days on corn meal supple- 

 mented with various feeds as shown below: 



It is shown that Lot III, fed linseed meal with corn meal, made 

 the largest and most economical gains. The lots fed middlings and 

 corn required from 13 to 16 per ct. more concentrates for 100 lbs. 

 gain than those fed linseed meal and corn. When germ oil meal, 

 gluten meal, or gluten feed was substituted for half the linseed 

 meal, the rate of gain was lowered and the amount of grain re- 

 quired for 100 lbs. gain increased. Gluten feed proved slightly- 

 more valuable than gluten meal or germ oil meal. Forbes writes 

 that the pork from pigs fed linseed meal was characterized by hard, 

 white fat. (200) 



872. Cotton-seed meal. — As now prepared, cotton-seed meal is 

 poisonous to swine. All the various proposed ways for safely feed- 

 ing this meal have failed under careful and continued tests. Pigs 

 thrive at first on the meal, but usually in from 4 to 6 weeks some 

 die — not all, as a rule, — but so many that all possible profits from 

 the use of this feed are lost. A few feeders continue to use the 

 meal, experience enabling them to avoid most of the losses. If cot- 

 ton-seed meal is not fed continuously for over 40 days and does not 

 form over one-fourth of the ration, and if the pigs are freely sup- 

 plied with green forage or grazed on pasture, the risk from this 

 feed is slight.
