be more accurate. The digestibility of the ash in the plain 

 pulp is uncertain, due, partly at least, to the small amount 

 present. There being only about Yi per cent, of ether extract 

 (fat) in beet pulp, it is not possible to secure digestion coef- 

 ficients for that ingredient. From the variations noted in the 

 digestibility of the different ingredients it is evident that the 

 several sheep differed in their ability to make use of the 

 different nutrients. 



Cocoamd Meal. 

 This product is the residue from the manufacture of cocoanut 

 oil, and is used largely in European countries. It contains 

 about 20 per cent, of protein and 8 to 10 per cent, of fat and 

 some 9 to 10 per cent, of fiber. The sample used was pur- 

 chased from the Edible Oils Company of New York.

2 Organic matter. 



This material shows a somewhat higher digestibility than the 

 average of European trials, due partly to its less fiber content. 



The digestibility of the fiber varied to such an extent as to 

 warrant the elimination of the fiber coeflBcient, Sheep V. show- 

 ing a slightly negative result, and the two trials with Sheep VI. 

 showing 7.01 and 39.71 per cent., respectively. It seems 

 probable that the addition of the cocoanut meal to the hay im- 

 proved the digestibility of the hay fiber, which accounts for the 

 apparently negative or variable fiber coefficients of the cocoanut 

 meal. The ash, protein, extract matter and fat all show a high 

 digestibility, and indicate this material to be a valuable protein 

 concentrate.
