cent as much meat-meal as corn is sufficient in the growing 

 and fattening of spring pigs while on rape." 



The feeding of the 7 to 8 per cent of tankage with the 

 corn was profitable here with the pigs on alfalfa. 



At the Ohio Station, one lot of pigs was fed corn alone 

 on rape, and a second corn and tankage on rape. These 

 pigs were spring farrowed and weighed about 44 pounds 

 each when the test began. The experiment lasted 77 

 days. The following table shows the results:

The pigs in this experiment were fed a very limited 

 amount of grain and the rates of gain in the two lots 

 were practically the same. Twenty-two pounds of tank- 

 age effected a saving only of 30 pounds of corn. Straight 

 corn was, therefore, practically as efficient as corn and 

 tankage. At the usual prices, corn alone was the more 

 profitable ration. In interpreting the results of this 

 trial, one should remember that no more than half rations 

 were fed.
