DIGESTION EXPERIMENTS WITH SHEEP. 



309 



The results of Period 14, Series XX., are rather surprising, and in a 

 way hardly to be explained, being noticeably below Series XXI., Periods 

 1 and 11, which are reasonably uniform. They will be discussed further 

 in considering the digestibility of gluten feed. Series XIX., Period 15, 

 has more hay in proportion to gluten feed, and the coefficients are some- 

 what below the other series, with the exceptions mentioned. 



Summary of Coeffi,cients of English Hay, Potato Starch and Diamond Gluten 



Meal — Basal. 



In order to study the digestibility of fiber in distillers' grains and corn 

 bran, a basal ration composed of a limited amount of hay plus potato 

 st':irch and Diamond gluten meal was used. This ration naturally con- 

 tained but little fiber, and would permit the intestinal juices and ferments 

 to exert their maximum effect upon the fiber of the two by-products. 



Sheep IV. in Series XIX. received 100 grams more hay and 25 grams 

 more gluten meal daily in the combination than did the other three sheep. 

 The coefficients of this basal ration are fairly uniform, excepting that 

 Sheep V. appeared to have digested noticeably more of the ration than 

 did the other sheep.
