Choosing a Forage Crop

rape proved the least profitable. The authors stated 

 that the vetch was of little value in the mixture. It 

 came on and made good growth in July and August, 

 but the pigs ate little of it. As the result of their observa- 

 tions, they strongly advise against the use of hairy vetch 

 as a hog pasture in Iowa. The returns in lot IV, in which 

 oats and clover were alternated with rape, were dis- 

 appointing. After the rape had been well eaten down 

 early in the season, the pigs were changed to oats and 

 clover. From late July until the end of the season, the 

 pigs were on the rape again, as the oats and clover fur- 

 nished practically no feed during this time. 



Oats versus other forages. 



In Table XLIV are shown the results of an experiment 

 at the Iowa Station 1 in 1911. In this test a comparison 

 was made of a mixture of oats, Canadian field peas, and 

 rape with oats alone, and with rape alone. The pigs 

 in all three lots were turned in June 13. At this date 

 the oats in the oats-alone lot were just beginning to head.
