Study on emission reduction control of various greenhouse gases in cowshed
Greenhouse gases refer to gases that can absorb long-wave radiation in the earth's atmosphere and cause atmospheric temperature to rise,among which carbon dioxide,methane,nitrous oxide and fluorine are the gases that have the most prominent impact on climate change.Greenhouse gas emissions from animal husbandry account for a large proportion of the total global emissions.Therefore,in order to reduce the impact of animal husbandry on climate change,it is particularly important to control greenhouse gas emissions from cowshed.At present,there are two main ways to control greenhouse gas emissions from cowshed:Improving the production mode and management mode of animal husbandry to reduce greenhouse gas generation,control greenhouse gas emissions through technical means.This paper explains the toxic effect of greenhouse gases emitted by cattle in cowshed,emphatically analyzes the related factors affecting greenhouse gas emissions and its control methods,discusses various greenhouse gas emission reduction control measures from the perspectives of feed composition and additive regulation,adsorbent placement in the cowshed environment,and environmental optimization outside of the cowshed,and analyzes the advantages and existing problems of the existing technologies,to provide references for promoting environmentally friendly,sustainable scientific livestock and poultry farming practices.
