Effect Of Conservation Methods On Cyanic Acid Concentration And In Vitro Digestibility Of Ceara Rubber (Manihot glaziovii) Leaves
The objective of this experiment was to determine the effect of conservation methods on cyanic acid (hydrocyanic acid, HCN) concentration of ceara rubber (Manihot glaziovii) leaves. Two types of natural drying methods [dried indirectly (IS) or directly (DS) under sunlight] or 3 silage additives [wit...

| description | The objective of this experiment was to determine the effect of conservation methods on cyanic acid (hydrocyanic acid, HCN) concentration of ceara rubber (Manihot glaziovii) leaves. Two types of natural drying methods [dried indirectly (IS) or directly (DS) under sunlight] or 3 silage additives [without molasses (0M), with 4% molasses (4M), or with 6% molasses (6M); DM basis] were applied to chopped ceara rubber leaves; each treatment was replicated in 5 replications. Results showed that fresh ceara rubber leaves contain 18.59% crude protein, 20.04% crude fiber, 32.73% neutral detergent fiber, 9.45% ether extract, 45.91% nitrogen free extract, and 0.22% HCN (DM basis). Greater decrease of HCN were shown by ceara rubber leaves with DS treatment than those with IS treatment (89.89 vs. 84.40%, respectively; p<0.05). Both the 4M and 6M treatments decreased HCN concentration (32.8 and 32.9 vs. 28.2%, respectively; p<0.05) and decreased pH (4.26 and 4.20 vs. 4.41, respectively; p<0.05) compared with the 0M treatment. Drying methods and silage additives did not affect in vitro digestibility of ceara rubber leaves. Data from this experiment imply that lower HCN concentration in ceara rubber hay can be achieved by drying those directly under the sunlight; while in silage, the HCN concentration can be decreased by adding molasses during the ensilage process. |
