FIFTY-THIRD ANNUAL CONVENTION 53 



ing nearly as rich in protein as is wheat bran. 



Next, I discussed the importance of the quality of 

 proteins, and pointed out that legume hay contains protein 

 of the right kind or quality to supplement the deficiencies 

 of the cereal grains. 



It was next pointed out that minerals are highly im- 

 portant in economical milk production, and the calcium was 

 the mineral constituent, in addition to common salt, most 

 apt to be lacking in dairy rations. One of the important 

 advantages of alfalfa hay or hay from other legumes is 

 that it is always high in calcium or lime content. 



Then I discussed the importance of the various vitamins 

 in stock feeding, and pointed out that only vitamin A and 

 vitamin D are apt to be lacking in the rations fed livestock. 

 Legume hay is rich in both of these vitamins, if it is well- 

 cured and green in color. 



There are, therefore, all of these important reasons for 

 growing plenty of legume hay on every stock farm. In 

 other words, these recent discoveries in stock feeding, re- 

 duced to their simplest terms, emphasize anew the import- 

 ance of large acreages of legumes in any well-planned sys- 

 tem of agriculture.
