Abstract: There is described a methane oxidation device for oxidation of methane from a digestive cavity associated with an animal, the device comprising a methane oxidation unit for oxidising methane; wherein the methane oxidation unit comprises an inlet portion in fluid communication with the external environment, the inlet portion further configured to be mounted to a hollow member in fluid communication with a digestive cavity associated with an animal, and further when the methane oxidation unit comprises an outlet portion in fluid communication with the external environment, so that methane from a digestive cavity associated with an animal is oxidised in the oxidisation unit prior to release into the external environment. There is further described an installation gun for installing a methane oxidation device.

Abstract: An animal emission monitoring device for positioning on cattle, the animal emission monitoring device comprising a snout member comprising a sensor unit for detecting the quantity of methane emissions and a positioning means for positioning the device on the head of an animal such that the snout member locates the sensor unit over the nostril of the animal.
