It takes effect immediately and it’s safely broken down in the cow’s normal digestive system into compounds already naturally present in the cow's stomach. As soon as the additive is not fed anymore, full methane production resumes and there are no lasting effects in the cow“</i><p>If that is correct, it also may end up being a highly profitable product for that company.
