160 RESULTS OF EXPERIMENTS IN SWINE FEEDING 
Following are some points taken from Professor Burnett's 
conclusions in connection with the investigation : 
When pigs were in a dry lot, the use of tankage as about 
5 per cent of the ration generally reduced the cost of the pork 
produced, 
All these experiments tend to show the suitability of corn 
and alfalfa as a ration for hogs. 
The lot receiving corn and steamed ground bone show gains 
at practically the same cost as the lot receiving 5 per cent 
tankage. The lot receiving ground bone required more feed 
for 100 pounds of gain, but the ground bone cost less per 
ton. 
Skim-milk at 20 cents per 100 pounds proved the most 
expensive supplementary feed used. 
Where supplementary feeds were used, the hogs generally 
made more rapid gains and reached heavier weights in a given 
length of time. 
In a test of the breaking strength of the bones of the hogs 
in the Nebraska experiments, it was found that they stood 
in the following order in point of strength of bone: Corn and 
ground bone, corn and tankage, corn and skim-milk, corn and 
shorts, corn alone. 
Tankage vs. Linseed Meal.—The Indiana Experiment 
Station reports four tests in which Swift’s digester tankage 
was fed in comparison with linseed meal as a supplement 
to corn, 
The proportion of tankage to corn meal was 1 to 10 in the 
first test, 1 to 32 in the second, 1 to 20 in the third, and 1 to 15 
in the fourth. 
In each test the proportion of linseed meal to corn meal 
was twice as great as the proportion of tankage to corn meal, 
the linseed meal being poorer in protein than the tankage.
