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 im which 100 pounds 
of a mixture of tive parts corn to one part linseed meal proved 
equal toucarly 148 pounds of corn wone. 
Tankage.— As the result of numerous experiments, the Ohio 
Experiment Station draws the conclusion that for dry lot feeding 
of pigs 3 to S 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 .\labama 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: 
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:

None of the pigs showed any ill effects from cottonseed meal

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