The Wheat By-Products (Middlings, Bran and Mixed Feed). 



The Association of Feed Control Officials have adopted tentatively the following 

 maximum fiber standards for the various grades of middlings, and these standards are 

 used in this bulletin as a basis for classification regardless of the name adopted by the 

 manufacturer: — 



Standard middlings 

 Flour middlings 

 Red Dog flour 

 Brown shorts 

 Gray shorts . 

 White shorts . 



Maximum Fiber 

 {Per Cent). 



9.5 



6.0 



4.0 



6.5 



5.5 



3.5 



The maximum fiber content set for wheat mixed feeds is 8.5 per cent. None of the 

 samples exammed exceeded this amount. 



The wheat brans examined were of good quality, but varied to a considerable extent 

 in composition. This variation is probably due to two factors, — the kind of wheat 

 milled, and the efficiency of the milling process employed. 



There is no class of feeding stuffs where the eye can be used to better advantage 

 in selection than the wheat by-products. Flour middlings should contain a liberal 

 amount of low-grade flour; standard middlings and brown shorts, enough middlings 

 to indicate that they are not finely ground bran; while wheat mixed feed, supposedly 

 the mill run of all the wheat by-products, should show the presence of considerable 

 middlings. Wheat bran, as well as all of the other wheat products, should be reason- 

 ably free from screenings, which are readily detected by the dark color of the mixture, 

 as well as by the characteristic odor imparted by the weed seeds. 



Rye Feeds. 



The two samples of rye feed collected were of good quality. They are nearly as 

 digestible as flour middlings, for which they can partially be substituted in dairy 

 rations. They are also very desirable as a feed for hogs. 



The Cereal Meals. 



All samples collected were found to be unadulterated. 



Hominy Feeds. 



The twentj^ brands examined were all of good quality. Their principal variation 

 appeared to be in fat content, due to the proportion of corn germ incorporated. Hominy 

 feed is an excellent substitute for corn meal, especially during the spring and summer 

 months, when corn meal has a tendency to cause trouble through heating. 



Dried Beet Pulp. 



The favorable influence of beet pulp, especially with cows on forced feeding for 

 advanced registry records, is too well known to require comment. The samples ex- 

 amined were of good quality and varied but slightly in composition. In purchasing, 

 avoid beet pulp that has been dried at such a high temperature as to be nearly black 

 in color.
