Methods of Feeding on Forage 



205 



The green feed available for these pigs was not abun- 

 dant at any time. The difference in the rate of gain, 

 and the amount of total concentrated feed required to 

 produce 100 pounds of gain in the two lots was very 

 small, though favoring slightly those fed the larger 

 proportion of tankage. With corn figured at 56 cents 

 a bushel and tankage 48 dollars a ton, the pigs fed the 

 smaller proportion of tankage made the cheaper gains. 

 One hundred pounds of gain on the 10 per cent of tankage 

 ration cost $4.28, while on the 5 per cent tankage ration 

 the cost was only $4.17, a difference of 11 cents. 



Corn alone on clover. 



At the Iowa Experiment Station one lot of pigs on 

 medium red clover was fed a ration of straight corn, 

 while a second similar lot on clover was given corn with 

 10 per cent meat-meal added. The experiment began 

 June 20 and closed November 10, covering a period of 

 141 days. The pigs were given full rations during the 

 last 85 days only. The results of this test are shown in 

 Table LXXV.
