3. DRIED APPLE POMACE FOR FARM STOCK. 



BY J. B. LINDSEY, C. L. BEALS AND J. G. ARCHIBALD. 



Introduction. 



Apple pomace is the residue after the extraction of the juice from apples. 

 This has usuallj^ been done by many small cider mills located in the vari- 

 ous countrj^ towns, but of late years the business of cider and vinegar 

 manufacture has become more centralized in large plants employing the 

 most modern machinery. The large establishments in Massachusetts 

 are those of W. W. Gary & Son, Lyons\alle; the E. F. Gerrj^ Companj-, 

 Lynnfield Centre; F. E. Jewett & Son, Lowell; New England Vinegar 

 "Works, Somerx-ille; and the Sterling Cider Company, SterUng. After 

 the extraction of the juice, the pomace has been thrown away or used 

 more or less by farmers in the vicinity of the mills. One large concern 

 reports that much of the pomace is taken by the farmers, well packed in 

 silos, and fed during the winter. More recentl}^, two manufacturers 

 (Sterlmg Cider Companj' and W. W. Cary & Son) have dried the pomace, 

 the latter company reducing its water content from 63.5 to less than 10 

 per cent. The value of this dried pomace for feeding purposes has been 

 the subject of our study, and the results are presented in this bulletin. 

 The material for the work was received from W. W. Cary & Son, whose 

 plant we have visited and inspected on two occasions. 



The number of cider apples produced in Massachusetts naturallj^ varies 

 much from year to year and no exact data on the subject are available. 

 Munson of the Massachusetts Department of Agriculture states that the 

 difference between the total crop of apples and the commercial crops for 

 the last five vears was as follows: —
