Description

Technical Field

[0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a chamber for measuring gas emission and digestion metabolism of dairy cows. Background Art

[0002] As global environmental problems become increasingly serious, energy conservation and emission reduction have become an urgent issue of widespread concern around the world. Animal production is considered to be one of the main sources of greenhouse gas emissions, especially in animal husbandry, where methane produced by rumen microorganisms in ruminants is an important greenhouse gas. In the past 100 years, the global warming potential of CH4 is 34 times that of CO2, of which ruminants account for 28% of the total methane emitted into the atmosphere, and it increases at a rate of 1% per year. The retention time of CH4 in the atmosphere is about 12.2 years, and the retention time of CO2 in the air is about 100 years. During the metabolism of ruminant rumen, about 2%-15% of feed is lost in the form of methane. It can be seen that CH4 emission reduction is a relatively fast way to mitigate climate change. Therefore, finding a way to reduce rumen gas production has become an important research task. However, there are relatively few devices for conducting respiratory gas measurement and digestive metabolism experiments in dairy cows, which brings inconvenience to related experiments, making some studies impossible to carry out, and related data cannot be accurately measured.
