Mixed feeds with few exceptions show only ordinary variations, 

 and are free from adulteration. An average of a large number of 

 determinations shows these feeds to consist of about 76 percent bran 

 and coarse middlings, and 24 per cent flour middlings or red dog. 

 They cannot be considered as being worth over 5 per cent more than 

 bran. Heilmati's mixed feed (see above) containing but 11 per cent 

 of protein, is very inferior. Several mixed feeds, without name, 

 said by dealers to have come from the Heilman Co. show only from 

 7.94 to 10.59 per cent protein. These feeds contain large quantities 

 of woody material ground fine. They are not more than one-half as 

 valuable as the genuine article, and all farmers are especially cau- 

 tioned against their use. The Lexington mixed feed is also below 

 the average in quality.

Malt sprouts and brewers' grains are of average quality. Protena 

 is evidently a mixture of several feeds. Its value would be about 

 equal to the better class of gluten feeds.
