108 MAINE AGRICULTURAL EXPERIMENT STATION. I907. 



to guarantee. The Bay State gluten feed did not come up to its 

 guarantee. The Jenks gluten feed is guaranteed higher than 

 the other gluten feeds but the 3 samples examined varied greatly 

 in composition, — one falling markedly below, while the two 

 other samples were practically in accord with the guarantee. 

 A good gluten feed can be expected to carry about 24 per cent 

 protein. Only two lots of gluten meal were found in the State. 



DISTILLERS GRAINS. 



Analyses pages 98 and 99. 



In composition, dried distillers grains resemble the gluten 

 feeds. They are derived from corn from which the starch is 

 removed by fermentation. They are more bulky than the glu- 

 ten feeds and for the most part run higher in protein. A feed- 

 ing test with distillers grains was reported in Bulletin 92 of this 

 Station. The Anchor Distillers Grains are low grade goods and 

 it is hoped that they will not be offered further in the State. 

 Ajax Flakes and Fourex are running a little below their guar- 

 antees in protein, but are well up in fat. 



BREWERS GRAINS. 



Analyses page 99. 



Brewers Grains are not largely used or sold in Maine. The 

 two brands that were offered in the State were of good quality, 

 free from acidity and were up to their guarantees in protein and 

 in fat. 



MISCELLANEOUS NITROGENOUS FEEDS. 



Analyses page 99. 



The Union Grains are quite largely used in the State. It is 

 probable that the other nitrogenous feeds here classed are not 

 so extensively used. It is interesting to note, however, that 

 practically all of these feeding stuffs come up to their guaran- 

 tees. A feeding test with Union Grains was reported in bulle- 

 tin 106 of this Station.
