162 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



over linseed meal in these tests, the difference is slight. 



Linseed Meal. E. B. Forbes, of the Missouri Experiment 

 Station, reports results of an experiment in which 100 pounds 

 of a mixture of live parts corn to one part, linseed meal proved 

 equal to nearly 148 pounds of corn alone. 



Tankage. As the result of numerous experiments, the Ohio 

 Experiment Station draws the conclusion that for dry lot feeding 

 of pigs 3 to 8 months old, an average of one part of tankage to 

 from 9 to 13 parts! of corn ordinarily produces larger gains 

 with a lower feed requirement per unit of gain than rations 

 containing larger or smaller percentages of tankage. 



The same station also states that there is strong evidence to 

 indicate that as a supplement to corn, skim milk has a distinct 

 advantage over tankage, particularly for young pigs. 



Cottonseed Meal. The Alabama Station reports tests with 

 cottonseed meal as a supplementary feed with corn. In two 

 tests the feed was mixed in the proportion of one part cotton- 

 seed meal to 9 parts corn, by weight. The average for two 

 years shows feed for 100 pounds gain as follows : 



Corn alone 727 Ibs. 



Corn and cottonseed meal 436 Ibs. 



In a third test, a third group was added to which was fed 

 1 part cottonseed meal to 2 parts corn. Feed required for 100 

 pounds gain was as follows : 



Corn alone 581 Ibs. 



Corn %o, cottonseed meal y,,,, 389 Ibs. 



Corn -/; cottonseed meal y,, 354 Ibs, 



None of the pigs showed any ill effects from cottonseed meal 

 in the three tests noted, but in another test, all of the pigs, but 

 one, fed cottonseed meal, were dead before the experiment had
