tain an appreciable amount of flour. A good grade of wheat 

 mixed feed is superior in feeding value to wheat bran and usual- 

 ly sells for a somewhat higher price. 



Wheat bran is usually sold as spring or winter bran, depending 

 upon the wheat from which it is made. While this distinction 

 serves to denote its derivation, it is not believed that the feeding 

 value between spring and winter bran differs to any extent, and for 

 this reason no distinction is made in the classification given in this 

 bulletin . Wheat bran is one of the commercial feeding stuffs whose 

 true value is not shown entirely by its chemical composition. In 

 spite of its relatively low digestibility and protein content, on ac- 

 count of its bulky nature, laxative effect and safe feeding quali- 

 ties, it can be advantageously used as a component of most 

 grain rations.

 collected, consisted of wheat middlings and 

 ground wheat screenings (weed-seed, chaff and shrunken wheat). 

 It sold for about three dollars a ton less than the straight mid- 

 dlings. 



The wheat mixed feeds adulterated with ground corn cob have 

 been in the market for some years, and at the time the present 

 feeding stuffs law went into effect were often sold as straight 

 mixed feed. So far as known, these feeds at the present time when 

 offered for sale in Massachusetts, are tagged in such a manner as to 

 deceive no one in regard to their true composition. The price

 not in proportion to their decreased feeding value. They are in
