© 2019 Elsevier B.V. Enteric methane emitted by ruminants is a nutritional inefficiency that contributes to global warming. Feeding substantial quantities of wheat grain to dairy cows has been reported to decrease enteric methane emissions compared with other feeds. Feeding methane mitigating agents such as nitrate, fat and 3-nitrooxypropanol (3-NOP) to ruminants have also been reported to decrease enteric methane emissions. This research involved three in vitro experiments that examined the combined effect of wheat grain with nitrate, fat or 3-NOP on in vitro methane mitigation. In each of the experiments, wheat grain or corn grain were incubated in combination with one of the three methane..
