190 RESULTS OF EXPERIMENTS IN SWINE FEEDING 



and states : " With pigs f rom four to ten months old, repre- 

 senting the various breeds of swine, an acre of rape, when 

 properly grown, has a feeding value when combined with a 

 ration of corn and shorts equivalent to 2346 pounds of a 

 mixture of these grain feeds." 



The Central Experimental Farm, Canada, reports feeding 

 six pigs on three-sixteenths of an acre of rape pasture from 

 August 14th until 'snow covered the ground. It is estimated 

 that the rape saved 156 pounds of meal, or an acre of rape 

 would save 832 pounds of meal. This is far short of the 

 Wisconsin returns, but the pigs were young at the commence- 

 ment of the trial, and it is the writer's experience that young 

 pigs do not make as good use of pasture as older ones. 



Rape vs. Clover. The Wisconsin Experiment Station re- 

 ports two trials with pigs on rape and clover. In the first 

 trial there were twenty pigs in each group, and in the second 

 trial twenty-one in each group. The pigs were from five to six 

 months old at the commencement. The following table shows 

 gains and feed consumed : 



It will be seen that the rape gave somewhat better gains 

 with a smaller meal requirement per 100 pounds gain than 

 the clover, though the difference was not great in the second 

 trial. 



Rape vs. Soy Beans. The Ontario Agricultural College 

 fed "soy beans and rape to pigs in pens, the green fodder being
