The Composition of Holocellulose Prepared from Various Forages and the Corresponding Feces

Dairy Husbandry Research Branch, USDA, Beltsville, Md.

ABSTRACT

The composition of holocellulose prepared from corn silage (9), alfalfa silage (9), timothy hay (4), mixed hay (5), oat hay, (5), bluegrass (4), orchard grass (9), cornstalks (4, 5, 6), straw (1, 2, 4, 9, 10) and corn cobs (4, 11) has been reported. Holocellulose samples prepared from the above materials contained residual lignin and protein. Comparing the composition of holocellulose from these materials is difficult since different methods of preparation and varying lengths of treatment were used.

Wise et al. (13) found that holocellulose from wood was very low in nitrogen when prepared by the acid chlorite method. Most wood, however, contains very small amounts of nitrogen before delignification. Reports of the lignin content of holocellulose prepared from wood are too numerous to review here and are adequately discussed by Wise and Jahn (12). Coldwell and DeLong (7) found that two or three acid chlorite treatments removed from 74.4 to 84.0% of the protein and from 77.2 to 87.1% of the lignin from extracted leaves of beech, birch, maple, and poplar trees.
