Abstract

The aim of this research was to study the effect of cinnamaldehyde on nutrients ruminal degradation and total production and molar proportion of volatile fatty acids in a ruminal in vitro system (DaisyII Ankom Technology, USA). The diet was composed of a mixture of barley seed: alfalfa hay (70:30) which was incubated with 4 treatments: without additive or negative control (NC), with monensin at 7.5 ppm or positive control (CP) and with cinnamaldehyde at 250 (C250) and 500 ppm (C500). The
inhibitory effect of cinnamaldehyde on disappearance of DM, NDF and ADF (from 48 to 72 h incubation time, P < 0.01) was similar to CP treatment. All supplemented treatments tended to decrease the potential degradability of DM, CP, NDF, ADF, as the effective degradability of DM, NDF and ADF. However, contrary to monensin, cinnamaldehyde increased total VFA production and did not affect molar proportion of VFA. The two doses of cinnamaldehyde evaluated showed the same effect. Results indicate that cinnamaldehyde modified in vitro ruminal fermentation.
