gluten feed, because of their concentration, are usually fed 

 in conjunction with foods less concentrated, as wheat bran. 

 Corn bran is composed of hulls removed from the kernels. 

 From 5 to 6 per cent of the grain consists of hull or 

 bran. Corn bran contains practically all the crude fibre 

 found in the grain. Its feeding value is low, but it may be 

 used with advantage in diluting concentrated foods by mix- 

 ing it with them. Corn germs are very rich in protein, 

 ether extract and in mineral matters, hence their adaptation 

 for being fed with caution to young animals. They com- 

 prise about 10 per cent of the kernel. Corn oil meal is the 

 residue of the germ that is left after the oil has been ex- 

 tracted from it. It may be fed in considerable quantities to 

 young animals. For such feeding it is valuable. When the 

 products of the factories are disposed of in a wet condition, 

 they are known as wet starch or wet glucose feeds. 



To cattle of all classes and ages, gluten meal has been 

 found not only a safe food, but also one that is relatively 

 economical. It is palatable also as well as safe. It may be 

 fed with much freedom to calves during the milk period and 

 subsequently, and also to growing animals to which concen- 

 trates are fed. The other foods to be fed with it will de- 

 pend on the object sought in feeding. When growth only is 

 sought, the complement of the gluten should be such food 

 as oats. When fattening also is sought it should be such 

 food as corn. As a food adjunct in fattening cattle at the 

 Ohio experiment station, it was found fully equal to oil 

 meal in making increase on the basis of relative cost when 

 the price paid for oil meal pound for pound was twice that 

 of gluten meal. For feeding cows it has been found fully 

 equal to cottonseed meal when fed so that the nutrients are 

 equal. When feeding gluten meal to cattle the aim should 

 be to feed it with some more bulky concentrate unless when 

 it is being fed to young calves. 



For sheep, gluten meal has not been much used as 

 concentrate. It should, however, because of its reasonably 

 fine character and high protein content, make an excellent
