We understand it is the intention to introduce this material 

 in our eastern markets. Our inspectors have ah'eady noticed 

 it occasionally. For convenience in distinguishinii; the dif- 

 ferent qualities, the sellers have divided the various products 

 into five grades, namely, " R," "X," "XX," "XXX "and 

 "XXXX." Those marked "R" are lowest in protein and 

 fat, and those marked " XXXX " highest. Some two years 

 since, this department secured several tons of these grains. 

 They were analyzed, tested for digestibility and fed to milch 

 cows. 



Composition of Distillers' Grains. 



The several grades showed between 7 and 8 per cent, of 

 water ; for the sake of uniformity, they were all calculated 

 to a 7 per cent, basis. 



The sellers state that the markings on "X" and "XX" 

 must have been reversed, as the " XX" grains should show 

 a higher percentage of protein than those marked "X." 

 The "R" grains, as the sellers claim, are the poorest in 

 composition, showing in this particular lot 1G.67 per cent, 

 of protein and 5.68 per cent, of fat, — about equal to the 

 amounts found in wheat bran. The others gradually increase 

 in these two ingredients, the "XXXX" showing 35.46 per 

 cent, of protein and 10.04 per cent, of fat. The fibre is 

 not excessive, being from 2 to 4 per cent, more than in bran. 

 The analyses show these materials to be valuable feeding 

 stuffs and worthy of the attention of feeders, providing they 

 are sold on a guaranty. The sellers state that a guaranty 

 will always accompany the different grades.
