Dried Apple Pomace. 



Note. — In periods 4 and 5 the pomace was fed unground. In periods 6 and 8 it was fed in the finely ground 

 state. Two sheep were started in period 8, but one became sick and had to be rejected. The previous trials, 

 averages of which are reported here for comparison, were with wet pomace. 



This material was studied quite extensively during the winter of 1920-21, with 

 respect to chemical composition, digestibility and value for milk production, and 

 the results published in Bulletin 205. It is a carbohydrate feed, having a negligible 

 amount of ash and relatively little protein. An average of the analyses of six samples 

 shows a dry matter content of 94.70 per cent, composed of ash 1.55, protein 5.88, 

 fiber 19.22, nitrogen-free extract 68.64, and fat 4.71. 



The results of seven single digestion trials show a fairly high degree of digesti- 

 bility as regards total dry matter, ash, fiber and nitrogen-free extract. The fat 

 is rather poorly digested, due doubtless to the fact that it is not true fat but waxy 

 material; and the protein is apparently not digested at all, or because of the small 

 amount present the coefficients are of uncertain value. Dried beet pulp, a some- 

 what similar type of feed, has a shghtly higher digestibility.
