摘要
1. A method for determining greenhouse gas, in particular methane, secreted by ruminants, in particular dairy animals (1), comprising: - measuring a signal associated with burping of a ruminant; and determining from the signal the number and / or duration of burping time. 2. The method according to claim 1, including determining the duration of each burping and summing the durations of time determined for each burping, to obtain the total duration of time. The method according to claim 1, including multiplying the number of burps by the release value, which is an indicator of the amount of greenhouse gas per burp. A method according to any one of claims 1, 2, or 3, comprising adjusting a specific allocation by multiplying by a correction factor selected from an animal-specific correction value, a reference correction value, or a greenhouse gas-dependent correction coefficient. A method according to any one of claims 1, 2 or 3, wherein the signal comprises an audio signal measured at a point where it is possible to measure burps of a ruminant, in particular an audio signal from the mouth (5) or the throat of a ruminant (1) .6. The method according to any one of claims 1, 2 or 3, wherein the signal includes a gas pressure signal in the intestines of the animal, and burping is considered if the pressure mentioned above drops over a predetermined time to at least a predetermined value. The method according to any one of claims 1, 2 or 3, comprising filtering the signal to improve the quality of the signal, while filtering, in particular, includes: - registering the simultaneous optical image of the ruminant and processing it using
