ference in glutens, but, as a rule, they are guaranteed to contain 

 27 per cent, protein. We find they hold up well in analysis. 



Question. — I am feeding in equal parts, corn meal middlings 

 with good ensilage, morning and night. Can I get better results 

 by adding gluten instead of the meal? 



Mr. Cook. — The chances are that if you feed a cow constantly 

 on that ration in time you will have no cow. 



Question. — Can we increase the butter fat in a cow's milk? 



Mr. Cook. — Sometimes. It would depend on the cow's normal 

 capacity. She has one, but one may force her below it. If the 

 cow lias been kept up to that condition, the fat cannot be per- 

 manently increased. I tried my best permanently to increase the 

 butter fat in a herd of eight cows, but could not do it. One of 

 the hardest things to understand is the feeding value of a food. 

 Wo must bear in mind that there is no difference between 

 the protein in the gluten, bran or cotton seed meal, but there is 

 a difference in its per cent, in these foods, so we must be governed 

 by that factor, and at the same time take into consideration the 

 palatability of a food. For instance, there is a greater per cent, of 

 protein in cotton seed meal than in bran, and, at present prices, 

 the cheaper to buy, but it is not nearly so palatable as the bran. 



A Farmer. — A mixture of cotton seed and wheat bran or 

 gluten, half and half sprinkled on the ensilage or other coarse foods, 

 has given me better results than has any other combination I 

 have tried, and I am surprised that the farmers do not feed more 

 cotton seed than they do. 



Question. — Which is the cheaper and best to buy for making 

 milk, wheat bran or corn meal? 



Mr. Smith. — The two foods are not comparable. One is a 

 starchy, the other a protein food. Both are necessary in the 

 make up of a cow's ration; the corn to produce the needed heat 

 and fat, the bran to produce the muscle and blood. 



Question. — What is the difference, if any, between winter and 

 spring wheat bran for feeding purposes? 



Mr. Smith. — Not very much. Experiments to quite a large 

 extent were made in Pennsylvania a year or two ago; as I re- 

 member it, the results did not show much, if any, difference. If 

 you can get good, coarse, flaky bran, do not worry over the differ- 

 ence in ;>rice. 



A Farmer. — I think that you will find in the Pennsylvania 

 report a small difference in favor of spring wheat bran. 



Mr. Smith. — The law docs not require an analysis of wheat
