WHEAT SCREENINGS. 



A gentleman in Kalamazoo sent to this station two packages of wheat 

 screenings for analysis, to learn something of their value as food for stock. 



The screenings consist of broken grain, shrunken wheat, chess, cockle, 

 seeds of weeds (pea vine especially), and fragments of straw, chaff, etc. 



The screenings were analyzed, and the results appear in the following 

 table :

Shrunken and immature wheat has little value for making flour, and many 

 persons suppose that its food value is of a low order. But young grains are 

 richer in nitrogen compounds than the fully ripened and plump berry. The 

 value of such grains for stock feeding is not to be measured by their flour 

 producing quality. These wheat screenings are worth more for stock food 

 than the same weight of plump wheat. The value of such materials when 

 ground and fitted for mixing with coarse materials like straw, etc., is obvi- 

 ous to the intelligent stock feeder. The material should be ground to kill all 

 seeds of weeds, as well as to secure complete digestion. 



In presenting the material for this bulletin, I wish to acknowledge the 

 valuable labors of G. L. Teller, my efficient assistant in the work of the 

 experiment station.
