METHANE REDUCTION IN BEEF CATTLE USING A NOVEL ANTIMETHANOGEN

摘要

An antimethanogen (AM) containing bromochloromethane (BCM) in a α-cyclodextrin matrix has been developed which has the potential to inhibit methane production when fed to ruminants (May et al. 1995). Once complexed, the volatile nature of BCM is reduced and release in the rumen is more predictable. Knowledge of the dose response, effect on animal productivity and residue status are prerequisites for registration of the complex. The aims of this study were to determine the dose response of the AM onmethane production, and to establish effects on feed intake, liveweight (LW) gain and residue concentrations in edible tissue.
