HATCH EXPERIMENT STATION. 



[Jan. 



Summary of Experitnents (Per Cent.'). 



The results show the total dry matter in apple pomace to 

 be about as dio-estible as in the best m-ades of silas^e. The 

 protein content of the pomace is small, — about 1 per cent., 

 — and it has not been possible by present methods to fix its 

 digestibility. Judging from the composition and digesti- 

 bility of the pomace, one would feel justified in assuming 

 that, pound for pound, it should approach in feeding value 

 an average quality of corn silage. 



(c) Experiments witJi Dairy Animals. 

 While this station has not carried out any exhaustive com- 

 parative tests with pomace and other coarse feeds, it has fed 

 the pomace a number of seasons to dairy animals. The 

 material was drawn fresh from the mill, and placed in a 

 large pile under cover. A noticeable quantity of juice 

 gradually drained from it, but it kept in good condition for 

 two months. The animals received from 15 to 30 pounds 

 dail}^ ate it readily, and the results were quite satisfactory. 

 In one case two cows were fed alternately fom' weeks at a 

 time on grain and hay, and on grain, hay and pomace ; 25 

 pounds of pomace were compared with 5 pounds of hay. 

 During the pomace period the animals produced 1,153 

 pounds of milk, and gained 24 pounds in live weight ; dur- 

 ing the hay period, 1,138 pounds of milk, and lost 6 pounds 

 in weight. On this basis, 5 pounds of pomace were more 

 than equivalent to 1 pound of hay. Judging from this 

 feeding test and from the composition and digestibility of 

 the pomace, it seems probable that 4 pounds, when fed in
