210 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



In the first test all the pigs were fed a mixture of ground 

 corn, wheat middlings, and bran; and in the second test, 

 hominy chop and middlings. In each test dry meal was fed 

 in the hoppers, and wet meal in the troughs. The results were :

Fia. 48. A type of self-feeding hopper in use on some large farms. 



First Test: Hopper fed. Average daily gain per pig, .71 pound. 



Meal consumed per 100 pounds gain, 520 pounds. 

 Trough fed. Average daily gain per pig, .73 pound. 



Meal consumed per 100 pounds gain, 478 pounds. 

 Second Test: Hopper fed. Average daily gain per pig, 1.26 pounds. 



Meal consumed per 100 pounds gain, 387 pounds. 

 Trough fed. Average daily gain per pig, 1.36 pounds. 



Meal consumed per 100 pounds gain, 348 pounds. 



Notice that in both tests trough-fed pigs gained the more 

 rapidly and cheaply, though the labor is less with hoppers. 



REVIEW. 



1. What was the old belief as to the value of cooking feed for swine? 

 What do the trials show? 



2. What is shown regarding the benefit of grinding small grains and 

 corn for swine? Under what circumstances does it pay? 



3. Give advantages and disadvantages of wetting or soaking feeds? 



4. Tell of the method of feeding by use of a hog motor grinder. 



5. Compare it with the hopper method. 



6. How does hopper feeding compare with trough feeding?
