tankage ration, a total of 437.17 pounds. As determined 

 by the feed required to produce 100 pounds of gain, 

 111 pounds of shorts were equal to 118.6 pounds of coca 

 and 6.87 pounds of tankage. 



The rations containing shorts could, no doubt, have 

 been made cheaper without sacrificing palatability or 

 balance, by increasing somewhat the proportion of corn 

 and reducing that of shorts. 



Tankage versiis soybean meal. 



Eight experiments conducted at four experiment 

 stations give information regarding the relative values 

 of tankage and soybean meal when fed to balance corn 

 for fattening pigs. In each of the tests here summarized, 

 the corn was fed as meal and the soybeans ground. The 

 experiments covered an average period of 70 days. A 

 compilation of the results obtained is shown in the sum- 

 mary. Table CVII.

 (Av. 8 Exps.)' 



The pigs fed an average of 12 per cent tankage in their 

 ration gained faster than those receiving a ration con-
