Fattening Pigs in the Dry Lot 



257 



The averaged results as given in the summary table 

 show that the pigs fed corn and tankage gained more 

 than 56 per cent faster than did those fed corn alone, 

 and were 46 pounds heavier at the close of the average 

 feeding period. The fact that the pigs fed corn and 

 tankage ate 1.3 pounds of feed daily in excess of that 

 consumed when corn alone was fed, testifies to the palata- 

 bility of this feed. 



Not only were the gains faster, but they were also made 

 on less feed. The feeding of 40.21 pounds of tankage 

 had the effect of saving an average of 165.74 pounds of 

 corn. In other words, as fed in these experiments, 

 1 pound of tankage in the balanced ration had the value 

 of 4.12 pounds of corn in the ration of corn alone. This 

 does not include the credit due the tankage for the faster 

 gains and earlier market finish, but is based alone on the 

 saving of corn effected in the production of a given gain. 

 The money value of tankage in reducing the cost of 

 gains, then, when fed under the average conditions repre- 

 sented in these experiments, would be as given in the 

 following table :

If no other supplements were available, the feeder 

 could afford to pay these extreme prices for the best 

 grade of tankage rather than feed corn alone. With the
