 authorities in many places to the use of this feed. If fed 

 in moderate amounts under proper sanitary conditions, they 

 are not objectionable. However, the use of them is so often 

 abused that some officials have found it easier to prohibit 

 their use than to regulate it. The objection comes from

 condition that exists if special care is not taken to keep the

This feed should not be used to exceed twenty pounds per 

 day, and should be supplemented with hay and some other 

 grain, such as corn. The greater part of the brewer's grains 

 now produced are dried, and in this form may be transported

 pounds may be used in the ration with advantage. At present 

 the larger part of this by-product finds a market in Europe. 



Mixed Feeds. No small proportion of the grain supplied

 and make such mixtures as may be advisable for the purpose 

 in view. The main purpose in view by the manufacturers 

 or dealers in preparing feed mixtures is to sell material of 

 inferior quality or some by-product of little or no value. One 

 of the most common ingredients of mixed feeds is oat hulls, 

 from oatmeal factories. In many cases the hulls are ground 

 fine to escape detection, while the claim may be made that 

 ground oats is a part of the mixture. A careful examination
