Weed Seeds. — Many feeds contain large quantities of different 

 kinds of weed seeds, added as an adulterant. One feed widely adver- 

 tised and sold in Maine was found to be made up of from 20 to 60 

 kinds of weed seeds. A germination test showed that this feed would 

 produce at the rate of about 2,000,000 noxious plants for each 100- 

 pound bag of the feed. 



Coloring Feeds.- — The prices of feeds have advanced so much that 

 the coloring process has commenced. Low-grade and inferior feeds, 

 by the use of coloring agents, are made to look fresh and green, and 

 now when we see a nice, bright-colored feed we don't know whether it 

 is the natural color of the product or a worthless imitation artificially 

 colored. 



Free Acid. — In the manufacture of gluten feeds, through careless- 

 ness enough free acid has been left in some of them to make their use 

 as a feed dangerous. 



ANALYSES OF SAMPLES OF CONCENTRATED FEEDING STUFFS, 



SEASON 1908. 



On the following pages will be found the results of the chemical 

 and microscopic examinations of the samples of concentrated stock 

 feeds collected by the inspectors of the Department, and those sent in 

 by farmers, dealers and manufacturers. These analyses, with the 

 discussion of the results which follow them, are deserving of careful 

 consideration on the part of all local dealers and also feeders.
