DRIED APPLE POMACE FOR FARM STOCK. 143 



The Economy of Dried Apple Pomace. 



The writer has emphasized for a long time that the farm is primarily 

 the carbohydrate factor}' upon which maximmn amounts of corn and 

 hay should be grown as roughages, supplemented whenever possible with 

 clover, alfalfa and possibly with soy beans. These latter furnish more 

 protein and ash than do the non-legumes, and are favorable to milk pro- 

 duction, growth and soil fertilit}^ Purchased feed should be in the form 

 of the protein concentrates; and carbohydrates such as corn, barley, 

 homin}% beet pulp and apple pomace, especially for growth and milk 

 production, should be purchased only when the supply of home-grown 

 feed runs low. 



To all intents and purposes, however, apple pomace is a home-grown 

 carbohydrate feed. Through dr3'ing, waste of this food resource is pre- 

 vented. The economy of attempting this conservation depends on its 

 cost. Ultunately the carbohydrate feed produced in this way must be 

 sold at as low a price as is asked for other carbohydrates. Whether this 

 will be possible cannot yet be stated, for the process is still new and the 

 cost factors not fully worked out. 



Summary. 



Apple pomace is now kiln dried in limited amomits, which insures its 

 preservation and greatly enhances its economic value. It is brownish in 

 color, of a mechanical condition resembling fine shavings, and has a 

 sHghtly acid taste. Chemical analyses show it to be a strictly carbohy- 

 drate feed with a high sugar content and lacking in true starch. It is 

 likewise high in fiber, but quite low in both protein and total ash. Phos- 

 phoric acid and potash make up fully 40 per cent of the ash. 



Experiments with sheep show it to be fairly well digested, especially 

 with respect to total dry matter, fiber and extract matter. Protein and 

 fat are rather poorly digested, an explanation for this being offered in the 

 text. 



For dairy cows, it may be fed to the extent of 4 pounds daily as a com- 

 ponent of the grain ration, or 7 pounds daily of the dry material may be 

 well moistened with water and fed as a substitute for a bushel of corn 

 silage. 



Experiments herein reported show it to be but slightly inferior to both 

 dried beet pulp and corn meal when fed to dairy cows as a component of 

 the daily ration. No objectionable flavor was noted in the milk, nor was 

 there any bad effect upon the health or condition of the animals. 



Fed only with other carbohydrate feeds such as hay, silage and corn, 

 dried apple pomace will prove unsatisfactory. The ration must always 

 be supplemented ^vith rich protein feeds such as cottonseed meal, gluten 

 feed and coconut meal. 



The chief use of apple pomace will be as a feed for dairy cows, young 

 stock and sheep. It is of doubtful value for pigs, and as a food for horses 

 it is not recommended.
