'In a series of carefully conducted experiments, Prof. 

 Evvard determined that the cost of 100 lbs. of gain when 

 oil meal was the supplementary feed with corn, was $5.62. 

 When tankage was used with corn, the cost per 100 lbs. was 

 $5.30. When equal parts of tankage and oil meal were used, 

 the cost of 100 lbs. gain was $5.04. 



"Another interesting fact that was brought out in these 

 series of experiments and one that will interest every 

 thoughtful swine breeder, is that hogs that are allowed an 

 opportunity to eat their feed at will, gain more rapidly and 

 on less feed that when fed by hand. In the experiments 

 conducted by Prof. Evvard, an equal number of 260-pound 

 sows were placed in two lots and both fed the same ration. 

 One lot was fed shelled corn in a self-feeder, and gained 

 2.4 pounds a day and required 457 pounds of corn for 

 100 pounds of gain. Another lot was placed in the care of 

 a practical and experienced swine feeder and fed by hand. 

 The gain was 2.09 pounds a day, and it required 478 

 pounds of corn for 100 pounds of gain. In another lot the 

 same number of sows of the same average weight as lots one 

 and- two, were fed shelled com and tankage. The com and 

 tankage was fed in a self-feeder and the daily gain was 

 2.35 pounds, and it required 470 pounds of com for 

 100 pounds of gain. Lot number four averaging the same 

 weight and the same number as lots one, two and three, 

 were fed shelled corn and tankage by hand and had the 

 watchful care of an experienced feeder and made a daily 

 gain of 1.03 pounds, and it required 483 pounds of corn 

 to 100 pounds of gain. 



"This experiment plainly shows that com supplemented 

 with proper concentrated feed and fed so that Mr. Pig has 

 an opportunity to feed himself at his own free will, makes 

 the most desirable .gain at the lowest cost."
