 milk, the average cost of production per loo pounds with 

 the tankage rations was $3.35, with the skim milk rations 

 $3.62, and with the check ration of middlings, corn meal 

 and water, $4.09. In the three original tests the tank-

 5.67 pounds skim milk per pound gain. In the check ra-

 amount of meal mixture required per pound gain was 

 4.09 pounds. The average daily gains from the three 

 tankage rations was .98 pounds ; from the three skim 

 milk rations. 1.08 pounds, and from the check ration. .8
