WHAT IS WHEAT MIXED FEED? 



According to the definition adopted by the Association of Feed Control Officials, 

 "Wheat Mixed Feed (Mill Run Wheat Feed) consists of pure wheat bran and the 

 gray or total shorts or flour middlings combined in the proportion obtained in the 

 usual process of commercial milling." In other words, it should be the combined 

 residual product of the flour mill exclusive of screenings. In order to determine ap- 

 proximately the proportions of wheat bran, standard and flour middlings found in the 

 wheat mixed feed sold in Massachusetts markets, an attempt was made to separate 

 the several ingredients by means of sieves. Two sieves were used: A, with 1 milli- 

 meter, and B, with ^ millimeter, perforations. Sieve A retained the bran, while the 

 standard and flour middlings passed through. Sieve B retained the standard middlings 

 and the flour middlings passed through. While this method is not exact, in that fine 

 bran and standard middlings to a certain extent passed through the sieves intended to 

 retain them, it is believed that the results are at least indicative of the amount of the 

 bran, standard and flour middlings in the products examined. The table following 

 gives the percentage of ingredients found in several brands of wheat mixed feed by the 

 method above described : —
