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 drj^ 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 com 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 ISTebraska experiments, it was found that they stood 

 in the following order in point of strength of bone: Corn and 

 ground bone, corn and tankage, com and skim-milk, com and 

 shorts, com 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 com. 



The proportion of tankage to com 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 com meal 

 was twice as great as the proportion of tankage to com meal, 

 the linseed meal being poorer in protein than the tankage.
