I. DIGESTION AND FEEDING EXPERIMENTS.* 



W. H. JORDAN AND C. G- JENTER. 



SUMMARY. 



I. The New Corn Product. 

 The claim that the removal of the pith from corn stover modi 

 fies the composition and increases the digestibility of the remain- 

 ing portions of the stalk and leaves is not substantiated by inves 

 tigations at this Station, (o) The pith was found to be much like 

 the whole stover in composition. (6) In a trial with three sheep, 

 corn stover with the pith was only one-half of one per cent less 

 digestible than similar stover without the pith. 



II. Actual and Calculated Digestibility. 

 In digestion trials with two fairly elaborate rations quite un 

 like in origin, the actual digestible matter closely approximated 

 in both cases to the quantities that were calculat'^d by the use of 

 figures from feeding tables representing the average composition 

 and digestion coeflScients of similar materials. 



III. Comparative Value of Rations from Unlike Sources. 



In an extended feeding trial with two rations in w^hich the com- 

 pounds that were the source of the digestible carbohydrates were 

 quite dissimilar, the ration containing the less fiber and a nitro- 

 gen-free extract richer in starch and sugar showed no superiority 

 over the other. Also by-products such as malt sprouts, brewer's 

 grains and gluten feed were successfully substituted for oats 



and peas. 



I. THE " NEW CORN PRODUCT." 



The cattle feeder is beset on every hand with new feeding 

 stuffs — new in name if not in kind. One of the latest of these is 

 "Marsden's Stock Food." otherwise called "A New Corn Product."
