Abstract
Peanut hulls were treated chemically in attempts to improve their digestibility as a roughage for ruminants. Reagents used were ammonia, sodium hydroxide, chlorine gas, calcium hypochlorite, dioxane/2,2-dimethoxy-propane and dimethysulfoxide/1, 2-dimethoxy ethane. Aerobic and anaerobic conditions were tested. Under the conditions of these experiments, only treatment with calcium hypochlorite, either as a slurry or anaerobically appreciably improved in vitro dry matter digestibility of the hulls (40% vs. 25%). The low digestibility of peanut hulls might be due to inherent properties in the cellulose fraction. This explanation is indicated by the low digestibility of true cellulose isolated from peanut hulls compared to that from other roughages sources. Copyright © 1974.
