Meanwhile, the author analyzed the effect of this change on agriculture and animal industry, and also analyzed its control measures in this article.. Key words: animal industry production, global climate change, methane, ammonia There is only one earth in the world, so the problem of the global environmental change is generally paid attention around the world. Increasing human activities leads to the deterioration of ecological environment. According to UNEP(Union Nations Environment Plan Department) and WMO(World Meteorology Organization), because of greenhouse effect, it is possible that average air temperature of the earth is increased by 0.5~2.0? , change takes place in the pattern of rain and snow, rainfall and evaporation are increased by 2%~13% and Asian monsoon system is strengthened. All these changes will have great impact on the utilization of land and agriculture in our country. Fluctuation and change of future climate, especially the effect of the warm-increasing of greenhouse gases, may further lead to the disaster of flood and drought. According to data concerned, carbon dioxide, methane and nitrogen oxide and so on are major gases resulting in greenhouse effect. 15%~20% of results of climate warming are due to methane, which is the second major greenhouse gas next to carbon dioxide and whose influence is 21 times that of carbon dioxide , so the problem of emission of methane is concerned by all professionals. During animal industry, the output of methane emitted from ruminants accounts for 1/5 of that in atmosphere. In particular, cattle produce the greatest amount of methane, being 2~3 times that of other ruminants. Other livestocks are also
