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 five parts corn to one part linseed meal proved 

 equal to nearly 148 pounds of corn alone. 



Tankage. The Indiana Experiment Station was among the 

 first to test tankage as a supplement to corn. In this trial, feeds 

 were valued as follows : Corn meal, $20.00 per ton ; shorts, $16.00 

 per ton; tankage $30.00 per ton. This method of valuing feeds 

 is very much more in favor of tankage, as compared with corn, 

 than the system followed in Nebraska. 



The cost of 100 pounds of gain was as follows : 



Lot I. 10 parts corn meal, 1 Lot III. Corn meal only $5.20 



part tankage $3.80 Lot IV. 10 parts mixture of 



Lot II. 5 parts corn meal, 1 corn and middlings, 1 part 



part tankage 4.00 tankage 3.60 



There were four pigs in each lot, and lot I gained 4.63 pounds 

 per day; lot II, 4.91 pounds; lot III, 2.68 pounds; and lot IV, 

 4.55: a striking illustration in favor of tankage. 



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 Yio cottonseed meal 1 / 10 , 389 Ibs. 



Corn %, cottonseed meal y 3) 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
