 oxpcriiiu'nt is iiit(MVstiu<^, since the inctliod of scpaijitin*^ tlic feces 

 was the same as that commonly used in exjM'i'imeiits with man, namely, 

 charcoal was given with the last meal before and tlu* lirst after the 

 test. This imparts a characteristic color (o the feces. 



^^^ it. .Jordan and C. (r. Jenter" studied with sheep the digestibility 

 of couuuercial oat feed when added to a grain ration. 



The digestiliility of some of th(^ nonnitrogenous constituents of a 

 number of feeding stull's was tested by (i. S. Fra])s'' in experiments 

 with sheep, the materials studied including timothy hay, green rape, 

 crab-grass hay fed alone and with cowpea meal, and corn bran and 

 rice bran. The constituents studied included the different members 

 of the carboh} drate group. According to the author the constituents 

 which make the nitrogen-free extract should be arranged in the fol- 

 lowing order as regards digestibility: Sugar, starch, pentosans, and 

 "remainder." The crude fiber he divides into pseudo-pentosans and 

 residue, the former making up from to 14.4 pei- cent of the crude 

 liber, and })eing as a rule less digestible. 



J. Fields and A. G. Ford'' studied the digestibilitv of a number of 

 coarse fodders with sheep, the different sorts of forage including Kalir 

 corn, corn, sorghum, black-rice corn, and milo maize. 



J. M. Bartlett'^ studied with sheep the digestibility of clover hay, 

 clover silage, corn meal fed with clover hay, hay (mosth^ timothy), 

 oats, oat and pea hay and silage, oat and vetch hay, two mixed feeds, 

 and corn germ. 



In experiments with sheep J. B. Lindsey* studied the digestibility 

 of millet, millet ha^', millet and soy-bean silage, corn and soy-bean 

 silage, ha}" (largely June grasses), meadow fescue, Kentucky ])lue 

 grass, tall-oat grass, distillery grains, oat feed, rye feed, Cleveland flax 

 meal, and a commercial feed. 



In an extended investigation of the amount of feed reciuired ))y sheep 

 for a maintenance ration, W. W. Cook' studied the digestibilitv of 

 timotfiy hay alone and fed with corn. 



C. G. Hopkins'' studied with steers the digestibilit}" of corn fodder 

 (ground corn and cobs and shredded stover) and shredded corn stover. 

 He found that the value of the material was increased by grinding and 

 shredding, shredded corn stover closely resem])ling timothv hay in 

 composition and digestibilit}'. 



II. E. Stockbridge,^' in experiments with steers, stvidied the digesti- 

 bility of cassava fed with cotton-seed hulls and cotton-seed meal. 



In a digestion experiment with steers made by H. K. Miller' the 

 digestibility of green velvet bean vines and ha^^ was studied.
