A Review of Greenhouse Gasemission Detection Methods for Ruminant Animals
Research on intelligent methods for detecting greenhouse gas emissions is currently a focal point in environmental and climate sciences.As of 2023,emissions from livestock contribute more than 14.5％ to global total emissions,predominantly sourced from enteric fermentation in ruminant animals.With escalating global climate concerns,the precise and efficient detection of these emissions is critical.Presently,greenhouse gas emission indices rely on specialized instruments such as respiratory chamber gas analyzers and methane laser detectors,each varying in principle,applicability,and accuracy.This paper provided an overview of the mechanisms and impacts of greenhouse gas production by ruminant animals,emphasizing a comparative analysis of detection methods including principles,applicability,and technological considerations.Evaluation of current methods reveals limitations such as environmental constraints,low precision,and high costs.Summarizing challenges in ruminant greenhouse gas emission detection methods,this paper offered insights into future directions aimed at developing more efficient,accessible and cost-effective detection technologies.
