Mr. Dulles: Let me say that I have taken the feed at exactly the 

 figures you have given us, because I have figured silage at $5 a ton and 

 hay at $18 a ton, cottonseed meal would cost $34 a ton, which is a little 

 more than you figure it (at an average of about $30), which is your figure. 



Prof. Larsen : The dairymen are doing it. 



Mr. Dulles : I do not think they do that on an 8,000 pound cow. 



Hon. Mr. Critchfield : You said something about the great value of 

 milk as a food. Which is the better, the milk which is rich in casein or 

 rich in butter fats? Which has the best value? 



Prof. Larsen: I cannot answer that question. Men who know 

 more about it than I do, do not agree on it, and men who know as much 

 as anybody, do not agree on it. Some claim that casein is more valuable 

 and others claim that butter fat is. They are entirely different. It 

 depends on what you are consuming with it. If you need fat to balance 

 up with some other food you are eating with the milk, then it would be 

 desirable to have fats; or if you are having fats in some other form, then 

 casein would be desirable. I can't answer that question. 



[The conference at . this point adjourned until 10 o'clock Friday
