MISCELLANEOUS INVESTIGATIONS 141 



rich in protein are found beneficial, just as they are beneficial 

 when corn is fed directly to the hog. Waters points out that: 

 " Hogs make better gains when following cattle fed corn and 

 clover, or cow-pea, or alfalfa hay, than when following cattle 

 fed corn and timothy, millet, sorghum, or straw for roughage." 

 He also states that hogs following cattle fed linseed-meal or 

 cottonseed-meal along with their corn ration make better gains 

 than those following cattle fed corn alone, the linseed meal 

 proving especially beneficial. In twelve years' experience he 

 has found no evil effects upon hogs following cattle whose 

 meal ration contained one-sixth to one-quarter cottonseed meal. 

 In summer feeding, access to a pasture will take the 

 place of other supplemental feeds, clover and alfalfa being 

 especially effective.
