THE DIGESTIBILITY OF CATTLE FOODS.

contain a high ash content, but the small amount digested 

 shows it to be of comparatively little value. 



The experiment indicates that screenings, when finely ground 

 and reasonably free from dirt, chaff and noxious seeds, possess 

 considerable nutritive value. It is likely to be found primarily 

 in the protein and extract matter of the screenings. 



Flax Skives. 

 Plax shives, sometimes incorrectly called flax bran, consists 

 of the ground refuse stalks and pods of the flax plant. It is 

 found on the market as a component of some molasses and stock 

 feeds. 



Summary of Coefficients, Flax Shives, Series XVII., Period VI. 



This experiment show^ed flax shives to have a digestibility of 

 about 45 per cent, as compared with 66 per cent, for wheat 

 bran. It contained nearly 35 per cent, of fiber of which about 

 one-fourth proved digestible, and must be pronounced as 

 distinctlv inferior for feeding. 



Cocoa Shells. 

 Cocoa shells are the hard, outside coating or bran of the 

 cocoa bean. Up to the present time they have been used but 

 little as a feedstuff, although their chemical composition would 

 indicate that they have considerable feeding value. Prelimi- 

 nary feeding experiments have shown them to be rather un- 

 palatable.
