■' The sample contains not less than lo per cent of screenings,, 

 which are mainly composed of weed seeds. An examination for 

 poisonous weed seeds shows the presence of some corn cockle, but 

 whether or not the corn cockle is present in sufficient amounts to be 

 injurious, can only be settled by physiological experiments." 



" I find that the sample contains, in addition to wheat middlings, 

 a certain amount of foreign seeds, among which are the following : 

 flax seed, cockle, mustard seed, foxtail and black bindweed. The 

 latter seed, as you are well aware, is often known as wild buckwheat. 

 Quite possibly the manufacturers refer to this when they state that 

 the product contains buckwheat." 



In the light of all the evidence furnished the Station has taken ex- 

 ception to the tag used as not conforming to the requirements of the 

 Massachusetts feed law (Section 6), and upon correspondence the 

 manufacturers have agreed to use a tag like the one reproduced below: 



New Occidental Milling Co. 

 Minneapolis, Minn. 

 Aloras, loo lbs. 



Protein, i6 per cent. 



Fat, 5 per cent. 



Fiber, 7.5 per cent. 



This feed is made of 90 per cent pure ' 

 wheat middlings and 10 per cent of care- 

 fully selected ground screenings. 



Wheat mixed feed should contain, with the exception of screen- 

 ings, all the by-products of the flour mill. Occasional samples are 

 noted which appear to be nothing more or less than wheat bran. 

 There appeared to be a noticeable improvement in the quality of the 

 mixed feed offered as to the amount of middlings incorporated, and 

 with a few exceptions the feeds were comparatively free from screen- 

 ings. A good quality of mixed feed has a feeding value somewhat 

 higher than wheat bran. 



Wheat brail was, with few exceptions, of the usual quality. Some 

 samples contained an appreciable amount of screenings. Several 

 manufacturers are now marking their bran, when screenings are 

 added, as " Bran and Screenings," in accordance with the United 

 States Department of Agriculture Pure Food Decision No. 90. While 

 wheat bran is a comparatively expensive protein concentrate because 

 of its relatively low digestibility, its other many desirable qualities 

 commend it as a valuable component of the dairy ration.
