44 ILLINOIS STATE DAIRYMEN'S ASSOCIATION. 



Q. — When you got a pretty good cow on the dairy farm, 

 are you changing them from the poorest of these? 



A. — No, sir, what do you mean. 



Q. — Why, I mean when you got a cow not coming up to the 

 standard and have a better one on the dairy farm, do you trade 

 them around? 



A. — No, sir, that would not be fair. The thing to do is to 

 raise the heifers from those, and keep all going right along. I 

 don't say we can keep up this 6.000 pounds of milk to the acre 

 right along. 



Q. — Will you express briefly why we want this protein ? 



A. — There are three classes of digestible nutrients, protein, 

 carbohydrates and fat. The protein is the white of an egg, the 

 lean of meat and that class of substance. Carbohydrates are the 

 starchy substances and fat, you know the vegetable race and but- 

 ter fat. The carbohydrates and fat cannot take the place of pro- 

 tein. We must have protein in the milk. No matter how much 

 carbohydrates and fat you have and no protein, you cannot pro- 

 duce milk. You should raise alfalfa. A great many farmers 

 of northern Illinois are raising it for the protein. Next is the 

 red clover for those who don't want to raise alfalfa. 



Q. — Alfalfa is a heavier crop to handle than red clover? 



A. — Farmers want to get aware of that fact. 



Q. — How about manure, can't you hold up fertility there? 



A. — Yes, sir, you can hold up fertility, but you get insects. 



Q. — It would pay to buy corn if you can raise alfalfa? 



A. — Possibly. But to illustrate. The farmers in Illinois 

 can raise their own grain.
