legitimately contain all of the screenings, dirt and chaff purchased 

 with the wheat regardless of quality. Wheat mixed feed may 

 be the so-called "mill run" or it may be a mixture of bran and 

 Red Dog put out by a jobber or wholesaler. A difference of 10 

 per cent in the feeding value is frequently noted between different 

 samples of mixed feed, depending upon the amount of flour con- 

 tained in the different brands. 



Some brands contained enough screenings to be considered 

 adulterated, but, in keeping with our policy of not entering cases 

 for prosecution during the year just past, offenders were simply 

 warned. In a number of instances wheat feeds were guaranteed 

 as containing screenings, which complies with the requirements 

 of the Massachusetts law. 



Wheat bran has from 5 to 10 per cent less feeding value than 

 wheat mixed feed. From the standpoint of nutrition, wheat bran 

 cannot usually be considered economical, but on account of its 

 beneficial effect on the animal, it is usually used as a component 

 of the dairy ration and is also quite generally used as an occa- 

 sional feed for horses. On account of its fiber content, it will 

 not prove as valuable for hog feeding as middlings. 



The remarks in regard to screenings in wheat mixed feed apply 

 with equal force to wheat bran. 



All of the wheat by-products ran quite uniformly true to guar- 

 antee in regard to protein, fat and fiber.
