The samples of unadulterated mixed feed collected, showed the 

 usual variations in the proportions of bran and middlings. Gener- 

 ally speaking, the larger the proportion of fiour middlings, the higher 

 the percentage of protein and the more valuable the feed. Farmers 

 should examine mixed feed before purchasing, and note if it contains 

 a noticeable quantity of fine material. 



It is customary, in many mills at least, to run the screenings, 

 ground or unground, into the mixed feed, and while the practice may 

 not be very objectionable in some instances, still the amount and 

 character of the screenings should determine whether it is permissi- 

 ble or otherwise. Screenings consist largely of light wheat, hulls, 

 pieces of straw, oats and weed seeds. The latter constitute a rather 

 large percentage, and are especially objectionable from the possi- 

 bility of introducing a pest on the farm, 



B/ijn, as a whole, averages cleaner and more uniform than 

 mixed feed, though more or less screenings are occasionally noted, 

 especially chaff and grain hulls. Farmers should refuse an article 

 containing any noticeable amount of such material. Light colored, 

 flaky, so-called Canada bran, contains rather more starch and less 

 protein than the American product. 



All wormy, caked and mouldy wheat feeds should be avoided. 

 Purchasers are advised to give preference to those articles that bear 

 the name of a reputable manufacturer or jobber, which are bright 

 and clean, and which have shown a high protein content by previous 

 analyses.
