FIFTY-THIRD ANNUAL CONVENTION 49 



which are on pasture or which get plenty of well cured hay 

 secure enough of vitamin A. 



Most of the cereal grains are low in this vitamin, but 

 it has been recently discovered by Dr. Steenbock at the 

 Wisconsin Experiment Station that yellow corn is fairly rich 

 in it, while white corn contains little or none. Among 

 human foods, Irish potatoes, wheat flour and beets are low 

 in the vitamin, while liver, yellow carrots and sweet pota- 

 toes are high in it. 



It is very essential that children secure plenty of the 

 fat-soluble vitamin in their diet, for most of the foods which 

 we eat are low in it. A lack of this vitamin, is undoubtedly 

 one of the causes of poor health in children throughout the 

 world. It has been found that twenty percent of the chil- 

 dren of school age in the United States suffer from malnu- 

 trition, and a much larger percentage in less progressive 

 countries. For this reason nutrition authorities all over the 

 world now emphasize the need of a liberal consumption of 

 milk and dairy products. 



In considering the use of milk as a food we must always 

 bear in mind that most of vitamin A is in the butter fat. 

 Therefore, skim milk, although it is an excellent food from 

 other standpoints, is not rich in this vitamin. 



In stock feeding a plentiful amount of the vitamin is 

 furnished if cattle, horses and sheep get an abundance of 

 well cured hay and good silage. If young pigs which are 

 not on pasture are fed white corn and skim milk, they will 

 often develop paralysis or die from pneumonia, due to a 

 lack of this vitamin. Pigs on pasture secure plenty of the 

 vitamin from the green feed they eat. White corn is safe 

 for winter feeding if a small amount of well cured legume 

 hay is fed along with it, even to young pigs. 



Vitamin B 



Next I will discuss Vitamin B, or the water-soluble 

 vitamin, as it is often called. Doubtless you have heard 

 of the disease called beri-beri, which formerly affected 

 many of the people in the oriental nations, such as the Chin-
