184 MASS. EXPERIMENT STATION BULLETIN 155. 



verted into its starch equivalent in the usual way, we find the 

 eocoanut meal furnishes 1,705 pounds of digestible matter and 

 the gluten feed 1,634 pounds. The eocoanut meal contains 88.4 

 therms of net available energy and the sample of gluten feed 

 82.7 therms. In case of gluten feed, Kellner requires a re- 

 duction of 10 per cent., making the therms 74.4 as against 88.4 

 for the eocoanut meal. It seems doubtful, however, to the 

 writer if this 10 per cent, reduction is allowable. It hardly 

 seems probable on the basis of composition and digestibility that 

 the eocoanut meal would have a much greater nutritive value 

 than would the gluten feed. 



3. Feeding Experiment with Cocoanut Meal, 1911. 



In order to test the relative efficiency of the eocoanut meal 

 as compared with gluten feed as a component of a dairy ration, 

 10 cows were fed by the reversal method in periods of five 

 weeks' duration. Hay and Avheat bran constituted the basal 

 ration to which were added definite amounts of either eocoanut 

 meal or gluten feed.^

1 Cow Betty, being particularly thin, was given 1 pound of corn meal daily as a part of the 

 basal ration in each half of the trial.
