Jeiiks gluten meal is somewhat lower in protein than Chicago 

 gluten meal, but contains more fat. It is incorrectly guaranteed 

 so far as protein is concerned. The gluten feed made by Doug- 

 lass & Company has 4 per cent less protein than guaranteed. 

 Buffalo gluten feed is carrying approximately its guaranteed 

 percentage of protein. The sample of Jenks gluten feed, guar- 

 anteed 27 per cent protein, very materially overrun the protein 

 content; while Bay State gluten feed carried 5 per cent less 

 protein than the guaranteed called for. Tiger gluten feed has 

 no substantial agreement with its guarantee. Warner's gluten 

 feed is about 2 per cent below guarantee. 



It is unfortunate that the gluten feeds and meals are so irreg- 

 ular in their composition and that different makes vary so 

 greatly. The gluten meals and feeds are desirable sources of 

 protein and if the manufacturers placed proper guarantees upon 

 their goods, there seems to be but little reason why this class of 

 feeding stuffs should not become as popular as they were a few 

 years ago. 



DISTlIvIv^RS GRAINS. 



Analyses page 85. 



In composition, dried distillers grains resemble the gluten 

 feeds. They are derived chiefly from, corn from which the 

 starch is removed by fermentation. They are more bulky than 

 the gluten feeds and for the most part run higher in protein. A 

 feeding test with distillers grains was reported in Bulletin 92 of 

 this Station. 



Two samples of Anchors distillers grains, guaranteed to carry 

 25 per cent protein and fat, were examined. These were very 

 unusually low grade distillers grains. Biles Fourex continues 

 to run in fair accordance with its guarantee. 



Union grains are a ready made mixture carrying the protein 

 and fat practically in accord with the guarantee. They are made 

 up of distillers grains, gluten feed, ground corn, gi-ound oats, 

 and oil meal. For the farmer who must buy all his feed, Union 

 grains at a fair price would probably prove profitable. As a 

 rule, however, oats and corn are profitable for cows when the 

 feeds are home grown and are expensive feeds to purchase. A
