high that most commercial dairymen combine it with other feeds 

 in which protein costs less per pound. Aside from the value of 

 the nutrients which it contains, it has a special value in a feeding 

 mixture ,as it gives bulk and adds to the palatabihty. Wheat 

 bran may be used when the rest of the grain ration is lacking in 

 palatability or is of a constipating nature. It is especially good* 

 when the roughage is all dry. The best grades of wheat bran 

 are of light weight, with large flakes. Some of the large milla 

 put the sweepings of the mill into the bran; therefore, it is 

 usually best* to buy the highest grade of bran, provided the mills, 

 grading it are reliable. The output of small country mills is 

 usually of excellent quality. Bran contains a high proportiou 

 of phosphorus and potash in its ash content.

. Standard wheat middlings or shorts are composed of the 

 finer portions of the bran together with the coarser portion of, 

 the flour. They are not quite so flaky as bran, are a little less 

 laxative, and contain a somewhat smaller quantity of ash. In 

 other respects they may be said to resemble bran closely. This 

 feed is somewhat pasty when moist, and consequently lacks 

 bulk. 



Linseed Meal. 



Digestible nutrients — Old process: Protein, 30.2 per cent; carbohy- 

 drates and fat, 47.7 per cent. New process: Protein, 31.7 per cent; car- 

 bohydrates and fat, 44.2 per cent. 



Linseed meal is a by-product of the manufacture of lin- 

 seed oil from flaxseed, and is produced under two processes, 

 known as the old and the new. Linseed meal or oil meal from 

 a physiological standpoint is one of the very best feeds. It is> 

 laxative, palatable, and a very good ''conditioner," but, like 

 wheat bran, its price is usually excessive for its nutritive value. 

 It has, however, a distinct place in a mixture in supplying pro-
