Methane produced by animal husbandry is the main source of agricultural greenhouse gas emissions, and reducing methane emissions has become the focus of studies in various countries. This article aimed to provide data support and scientific basis for promoting the process of methane emission reduction in animal husbandry and realizing the green and sustainable development of animal husbandry. The long-term statistical data of the FAOSTAT from 1961 to 2019 were used to analyze the changing trend of methane emission from global animal husbandry. The results showed that there were significant differences in estimated methane emissions from animal husbandry in various regions of the world from 1961 to 2019, and the overall trend was increasing. Methane emissions from ruminants increased from 68.047 9 million tons in 1961 to 103.529 1 million tons in 2019, accounting for 96.98% and 97.51% of the total methane emissions from animal husbandry. Among different species of ruminants, the top three methane emissions were beef cattle, dairy cattle, and buffalo. Its emissions increased from 34.988 7 million ton, 18.615 6 million ton, and 5.209 8 million tons in 1961 to 56.661 6 million ton, 19.960 4 million ton, and 12.083 3 million tons in 2019, respectively. India, China, Pakistan and other countries were major livestock producers, and the output of ruminants such as cattle and sheep ranked among the top 10 in the world. Its methane emissions are also increasing, and the increase is more and more rapid. On this basis, this article proposes that a multi-pronged approach can be taken to reduce methane emissions from animal husbandry. At the policy level, we should establish statistical data and measurement standards for methane emissions from animal husbandry, tax greenhouse gas emissions from animal husbandry or allow them to participate in the carbon market, establish an incentive mechanism to encourage farmers to reduce methane emissions from farms, and enhance the awareness of climate change among producers and consumers. At the production level, we should improve the quality of forage grass, adopt reasonable grazing management strategies, add feed supplements, optimize genetic selection, and improve the utilization level of livestock manure. At the consumer level, we should reduce the waste of meat and dairy and reduce or replace animal-based diets with plant-based diets as a combination of strategies to reduce methane emissions from animal husbandry.
