Prof. Mumford — Ihere is very liltle nutriment in the cob, it is 

 sometimes an advantage to lessen the ration, it promotes digestion, 

 averages real nutrition in the corn meal better. It would probably be 

 just as efficient, if not more, to mix the corn meal with chaff. 



My experience in grinding corn and cob meal is if you grind the 

 cob fine enough so that it is finished as a feed, it will cost more than it 

 is worth. It is of no advantage to feed cob the way it is ordinarily 

 ground in large pieces. However, where the experiment stations have 

 carefully investigated this matter and have ground the cob fine enough, 

 it is true that a pound of corn and cob meal has been as valuable as a 

 pound of pure corn meal and we might assume that it is, when mixed in 

 that proportion, of the same value as a poimd of corn meal, but you 

 must always carry with that the idea that it must be ground fine, and 

 there's the rub. 



Q. Is the corn worm or its fungus injurious to live stock that is 

 fed on such corn? 



Prof. Mumford — That is a question that has agitated a good many 

 men in the last few years. 



Mr. Gabbert — It is not the worm, it is the dust that injures the horses 

 more than cattle. 



Prof. Mumford — It seems to be the general impression that there 

 is some injury following the feeding of such corn to animals. Whether 

 from insects or dust, it is not as good corn as corn not worm-eaten. 



Q. Is it better to feed cotton seed meal to beef cattle in con- 

 nection with corn? 



Prof. Mumford — We have fed cotton seed meal a little to beef 

 cattle at the Experiment Station for seven years, and it has been our 

 experience in almost all of these experiments that when corn is worth 

 50 cents a bushel and cotton seed meal is worth $22 to $24 a ton that 

 it does pay to feed cotton seed meal. 



There are two things that we aim at in feeding cattle, we aim to 

 finish them to a point where they will satisfy the demands of the market 

 and to make the gain necessary to produce that finish at the smallest 

 possible cost. If you consider only the increased gain from a given 

 amount of grain, it does not always pay to feed the cotton seed meal. 

 A hundred pounds of corn fed on blue grass pastures will produce the 

 gain more cheaply than the corn and cotton seed meal can but the 

 cotton seed meal will fit them for sale very quickly. 



It sometimes pays to feed a small amount of corn and cotton seed 

 meal when it would not pay to feed a large amount. 



O. Should each farmer have a corn breeding plat next year?
