Digestibility coefficient apparent

Cellulose digestibility declined with the additions of sawdust, Table VI. This was expected since extensive nylon bag digestibility data for various waste wood materials including oak sawdust revealed apparent dry matter digestion coefficients below 20, usually less than 5, Table VII.
