gotten better results with the oil meal. The only explanation I can 

 give is, that the steers relish oil meal better than cotton seed meal. 

 We find they walk up to the racks with a little more enthusiasm, 

 and I believe the difference we get is due to the higher palatability. 



Question: Which do you find is the most loosening on the 

 bowels? 



Prof. Smith: I haven't noticed much difference. We do not 

 find that in either case they are too laxative ; the bowels seem to be 

 in good shape most of the time. 



Question : Have you conducted any experiments with molasses 

 feed? 



Prof. Smith: No. I think we ought to deal with the form of 

 food that is constant. When you are out of that material on the 

 farm, then it might be well to take up secondary material. 



The trouble with these molasses feeds and feeds of that nature, 

 they are not the same from one year to the other. Oil meal is con- 

 stant, and so is bran. 



We will take up next a thing I think will interest you. I have 

 shown to you, I think, by these experiments, that if you are feeding 

 corn and prairie hay, or corn and straw, something like oil meal is 

 desirable, or cotton seed meal. 



Can we get along mthout the commercial protein food, if we 

 have alfalfa hay? 



I will direct your attention to the following table :
