Gluten feed : The quality proved similar to last season. The 15 

 samples taken averaged in protein 24.71 percent and in fat 3.02 

 percent. The protein guarantees, however, ranged from 27 to 28.5 

 per cent and the fat from 2.50 to 3.38 per cent, a deficiency of 

 over 3 per cent in protein. The excuse of a temporary fall- 

 ing off due to inferior corn can no longer be considered. The 

 feed must substantially maintain its guarantee or lower tigures 

 must be adopted. It is believed that a guarantee of 25 per cent 

 would more nearly express the average amount of protein likely 

 to be contained in this feed. There was no intentional adulteration,, 

 except possibly an excess of hulls in some cases. 



Distillers'' dried grains : The seven samples collected 



Distillers' were free from adulteration and of satisfactory 



By-Products, quality, averaging in protein 33.08 per cent and in 



Page 12. fat 12.93 per cent. 



Mali sprouts : The five lots sampled were of good 

 quality with a protein content of 27.65 per cent. 



Four samples of flour middlings and eight of stand- 

 Wheat ard middlings were collected. The fiour middlings 

 By-Products, are usually the more valuable. A sample of inferior 

 Pages 12-15. flour, testing only 14.30 per cent in protein, was mis- 

 branded " red dog ", whereas, red dog should con- 

 tain 18 to 20 per cent. Millers are cautioned against such 

 misrepresentations. 



Standard middlings, or middlings as the term is employed by. 

 various shippers, has no definite limitations. Some samples con- 

 tained a considerable proportion of red dog. while others, both in 

 appearance and analysis, closely resemble finely ground bran or 

 mixed feed. One sample was inferior containing but 15.14 per 

 cent of protein. 



Mixed feed : This is a mixture of varying proportions of bran 

 and middlings. Of the 34 samples taken, one was below standard 

 and three others contained foreign admixtures. Several were guar- 

 anteed, which is certainly commendable. The practice of running 

 the screenings, ground or unground, into the mixed feed is well 

 known, and while it may not be very detrimental in some instances, 

 still the amount and character of the screenings should determine 

 whether it is permissable or otherwise. Many samples contained 

 straw, hulls and weed seeds. The latter are especially objectionable.
