Feeds and Feeding. 



was confined in a lot free from vegetation and fed corn. All 

 were supplied with coal -slack, salt and water. The first period 

 in each trial lasted eight weeks and the second four weeks. The 

 averages for the four trials are given below: 



Trials with pigs fed corn on blue-grass pasture, or corn only Illi- 

 nois Station. 



We learn from the above that the best returns were secured 

 when giving a half feed of corn on blue-grass pasture during the 

 first period of eight weeks, then following for the next four weeks 

 with a full feed of corn, the pigs still running on pasture. Under 

 these conditions 441 pounds of corn gave 100 pounds gain. Where 

 the pigs were given a full feed of corn at all times while on past- 

 ure, 507 pounds of corn were required for 100 pounds of gain. 

 The check lots fed in yards without grass required 629 pounds of 

 corn for 100 pounds of gain. There was a saving of 30 per cent, 

 when a half feed of corn was given on pasture, and of 20 per cent, 

 when a full feed was given, as compared with feeding hogs in the 

 lot without pasture. 



878. Teeding pigs on pasture only. The trials reported by Mills 

 (875) show that pigs may make fair gains on pasture alone when 

 alfalfa is the main forage plant. Morrow 1 reports that all at- 

 tempts to carry pigs On blue-grass pasture without feeding grain 

 resulted so unfavorably that he was forced to give up experiments
