FIFTY-SECOND ANNUAL CONVENTION 45 



we advise people to consume more dairy products in gen- 

 eral, that they are going to be benefited thereby in addi- 

 tion to benefiting their pocket books, so we can be good 

 business men and altruists at the same time. 



From the standpoint of stock feeding, the most im- 

 portant thing with reference to vitamine A is this: vitamine 

 A is contained in large amounts in all green-leaved plants. 

 Right away that means that all the livestock on pasture 

 do not suffer from a lack of vitamine A. Furthermore this 

 vitamine is not destroyed when hay is cured well, so that 

 the good green color is retained, therefore all livestock 

 which consumes fairly liberal amounts of good, well-cured 

 roughage get an abundant supply of vitamine A. That 

 frees us from a great deal of worry about vitamine A in 

 stock feeding, does it not, that one general fact with ref- 

 erence to high content in green-leaved plants. That means 

 when stock is fed plenty of well-cured hay we do not need 

 to worry about vitamine A. 



When feeding swine and poultry there may be a de- 

 cided lack of vitamine A because these animals do not eat 

 much roughage. Yellow corn is rich in vitamine A, while 

 white corn is lacking in it. We found out in experiments 

 with pigs that we could kill young pigs by feeding them 

 white corn, lacking vitamine A, and milk with plenty of 

 water and so on. This was due to a lack of vitamine A, 

 and also another vitamine. However, by simply mixing in 

 five pounds of chopped alfalfa hay, good, well-cured al- 

 falfa hay, the situation was entirely changed, and on a 

 combination of ninety pounds of white corn and five pounds 

 of chopped alfalfa and skim milk, the pigs would do just 

 as well as on yellow corn and skim milk. 



In feeding white corn to swine and poultry in the win- 

 ter time, be sure you have some other feed furnishing 

 plenty of vitamine A or you may run into grief. I am not 

 talking primarily about swine feeding, but I will interrupt 

 at this time to state that in feeding swine the two most 

 important things are an abundance of growing pasture dur- 

 ing the growing season for all pigs and hogs, and also 

 legume hay for all pigs in the winter time. The same im- 

 portance of vitamine A applies to poultry feeding.
