of both the North and the South. In every section of 

 the country, some variety of clover is grown successfully 

 for forage purposes. Crimson clover is an annual possess- 

 ing wide adaptations, particularly suited to the South 

 Atlantic states. It provides valuable forage for hogs 

 during the winter. Varieties of Bur clovers are success- 

 fully grown and used as forage crops for pigs in the South 

 and West. They are considered valuable supplements 

 in Bermuda pasture. Lespedeza, or Japan clover, is one 

 of the most valuable legumes of the South. It is an 

 annual, but reseeds itself every year. It does especially 

 well on poor sandy soils and should be of large value as 

 a forage for pigs, either as a part of permanent pastures 

 or as a specially grown crop. 



Investigations by Evvard and Kennedy of the Iowa 

 Station ^ would indicate that sweet clover, especially the 

 first year's growth, has considerable value as a forage 

 for pigs. When fed a ration of ear corn, with 10 per 

 cent meat-meal during the last 57 days of the period, 

 twenty-two 38-pound pigs were pastured on an acre of 

 sweet clover from June 22 to November 10. The good 

 results obtained are shown by the fact that the pigs made 

 an average daily gain of 1.02 pounds at a cost of 3.38 

 pounds of grain feed. The results secured from the same 

 plot by pasturing the second year's growth the succeeding 

 year, however, were very much less favorable. This 

 year the pigs made an average gain of only .53 pound 

 daily, while other pigs in the same experiment on rape 

 and alfalfa gained, with the same grain rations, more 

 than one pound daily. The poor results from the second 

 crop were attributed to the extremely coarse woody 

 nature of the growth. (See Table XL, page 161.)
