bined. At the present time I consider gluten meal and corn stover 

 one of the very best feeds for the production of milk. I consider that 

 gluten meal is among the very best of the dairy foods. 



QUESTION: '-If the flush of feed does not affect the butter-fat- 

 content of milk, does the flush of feed change the cheese-content to 

 the milk?" 



PROF. COOKE: The present idea is that the cheese-content and 

 butter-fat-content rise and fall simultaneously. Take milk between 

 three and a half per cent, and four and a half per cent, of fat and the 

 probabilities are that the butter value and cheese value will rise and 

 fall almost exactly the same. Then when you get milk higher than 

 four and a half per cent. — when you get up to six or seven per cent, in 

 milk, the cheese value probably does not rise quite as far as the but- 

 ter value. 



QUESTION: *'Does the application of the milk-stool cause the 

 cow to retain a certain amount of butter-fat, or is it because she re- 

 tains a portion of her milk that contains the greater portion of the 

 fat?" 



PROF. COOKE: It seems to be the fact that she just holds up 

 the strippings, does not let down the last part of the milk. Of 

 course you know the last part of the milk is the richest. 



MR. HOWDEN: Don't you get it the next milking? 



PROF. COOKE: No, you don't. I don't know why, but I know 

 the fact that you don't. 



QUESTION: "What is the proper height of an ideal cow-stable?" 



PROF. COOKE: Well, a stall — I don't know the exact measure- 

 ment — the Bidwell stall is about four or four and a half feet high; I 

 think it should be high enough so that there is no danger of the ani- 

 mal getting over it. The less material you have in it, the better. If 

 a stable is meant^ it should not be lower than eight feet anyway, 

 and ten feet would be better. There is no necessity of its being 

 higher than ten feet that I know of except where there is no loft 

 over it, then of course, in the center, under" the cone, it must be 

 higher. 



QUESTION: "Will cows produce more milk at three milkings in 

 a day than at two if milked at regular intervals?" 



PROF. MAIRS: I am inclined to think, in general, they will, but 

 not enough more to pay for the extra milking. There are some 

 cows which it is found necessary to milk three times a day when giv- 

 ing a very large quantity of milk, but for an ordinary cow it is not
