Pork Production 



With 56-cent corn and $40 a ton tankage, the cost of 

 producing 100 pounds of gain would be practically the 

 same on the two rations. The more rapid gains of those 

 fed tankage, however, would indicate that the tankage 

 feeding would be profitable when an early finish is de- 

 sirable. 



Oats, Canadian field peas, and rape. 



Another experiment at the same station sought to de- 

 termine the best proportion of meat-meal to feed pigs 

 while grazing a forage mixture of oats, Canadian field 

 peas, and rape. These pigs were full fed during the last 

 100 days only, although receiving liberal rations during 

 the first 60 days. The experiment began June 13 and 

 lasted 160 days. The results are shown in Table LXXVI.

 WITH Corn to Pigs on a Mixture of Oats, Canadian 

 Field Peas, and Rape ' 



In this experiment, the smaller proportion of meat- 

 meal produced the cheaper and more economical gains, 

 and practically as rapid.
