 which also resulted in somewhat larger gains in wei.ulit. 



TUgesfion experiments iritli steers. — E.\i)ei-iinents were made with 4 

 grade Shorthorn steers to determine the digestibility of shredded corn 

 fodder and wheat bran fed in different ways. The methods followed 

 were essentially the same as those used in previous tests rejiorted in 

 Bulletin 20 of the station (E. S. K., 5, p. GO). After a preliminary i)eriod 

 of from o to 12 days duration, tlie digestion experiment i»ro])er lasted Vt 

 days. The composition of the corn fodder and the wheat bran is given. 

 The coi'fticieuts of digestibility obtained in each case were as follows:

• The bran used in this experiment was western bran. The com])osi- 

 tion and digestibility of old-process ea.sterii wheat bran is (juoted for 

 comparison. 



"The wettinji; of the fodder wlieii (Vd alone, and also when fed with ,£irain, made 

 it more digestihle. The nietliod of feedinjj the ration as a 'mixed i'eed ' j;avo u 

 larger percentage of digestible matter tlian any o-f the methods tested. From these 

 facts it is safe to say that the method of making a mi.xed feed of a ration is the hcst 

 method to adopt in order to liave the most complete consnniptiou and the hest 

 returns for the food consnmed. 



"The results of the digestion experiment show western wheat hran to be far better 

 than commonly supposed, and also that it is nearly as digestible as old jirocess bran." 



During- 14 days 2 of the steers were fed the dry corn fodder and bran 

 separately and two received the ration mixed and wet. The amount of 

 water consumed and tbod wasted was recorded in each case. Less food 

 was wasted when the second method of feeding was followed. Trac- 

 tically the same amounts of food and water were consumed in each case.
