PASTURE AND SOILING CROPS 189 



Station compared rape with alfalfa for pigs averaging 52 

 pounds at the conunencement of the experiment. Ten pigs 

 were used in each lot. Following are daily gains per head 

 and pounds of grain consumed per 100 pounds of gain : 



Daily Grain consumed per 



gain. 100 pounds gain. 



Lot 1. No pasture 1.04 pounds 371 pounds 



Lot 2. Rape pasture 1.09 pounds 301 pounds 



Lot 3. Alfalfa pasture 1.10 pounds 200 pounds 



An acre of rape was required for ten pigs, but half an 

 acre of alfalfa was sufficient for the same number. 



An acre of rape pasture produced 202 pounds of pork, and 

 an acre of alfalfa pasture produced 408 pounds of pork. 



" This experiment emphasizes the superior value of alfalfa, 

 and likewise emphasizes the value of dwarf Essex rape, which 

 can be seeded in the feed-lots that would otherwise go to 

 waste or grow up to weeds, and be made to pay a handsome 

 profit on the investment," 



Rape for Pasture. — At the Wisconsin Experiment Station, 

 Craig conducted two experiments with hogs on rape. In the 

 first experiment, 10 hogs, about eight months old, were pastured 

 on one-third of an acre of rape for 76 days, and fed com and 

 shorts in addition. Another lot was fed in a pen on com and 

 shorts only. In the second experiment, 19 hogs were pastured 

 seven weeks on six-tenths of an acre of rape, as compared 

 vdth a similar lot in pens on grain only. 



In the first trial one-third of an acre of rape was equivalent 

 to 1062 pounds of grain, and in the second trial six-tenths of 

 an acre of rape was equivalent to 1330.2 pounds of grain. 

 Therefore, in one case an acre of rape was equivalent to 3186 

 pounds of grain, and in the other to 2217 pounds of grain. 



Later, Carlyle, of the same institution, repeated the work.
