HATCH EXPERIMENT STATION, 



[Jan. 



1 Organic matter. 



The soy bean, in common with other concentrates rich in 

 nitrogen, frequently causes digestive irreguhirities. In the 

 present trial Sheep HI. was not able to digest the feed as 

 thoroughly as Sheep II. The same condition was apparent 

 last year, although not quite as marked. It is evident that 

 the beans are as a rule quite thoroughly digested, especially 

 the protein and fat, which are the two important constitu- 

 ents. The coefficients for the fiber are, of course, incorrect, 

 due probably to the favorable influence of the rich protein 

 concentrate in increasing the digestibility of the hay carbo- 

 hydrates. The small amount of fiber present — about 5 

 per cent. — renders a knowledge of the exact percentage 

 digestible of minor importance. The extract matter was 

 also largely digested, — probably 80 or more per cent., — 

 although the trials made thus far have not given sufficiently 

 definite results to enable one to fix any exact coeflicient. 



Hominy Feed, or Chop. — As used for cattle feeding, this 

 consists of the hull, germ, some of the gluten and soft starch. 

 The two samples tested Avere of good average quality. The 

 results of six trials are presented. Three of them were made 

 with old sheep in 1903, and three with young sheep in 1904.
