Animal production and its products processing produce the nutritious food for human being, however their wastes with content of nitrogen, carbohydrate, lipid, pathogens, additives and so forth also cause the serious pollution for soil, water and air. The objective of this paper is to present the reason, impact and solutions for mitigating the pollution caused by animal wastes, enhancing performance, improving income and developing sustainable animal production. The current, useful and efficient managements and treatment technologies for the wastes are presented such as reducing animal heads associated with using manure as organic fertilizers for crops; making composts;  applying “All in one” and biogas technologies; using biological padding and recycled waste bedding; and manipulating dietary nutrition, using total mixed ration (TMR), lipid supplementation, etc. for ruminants to improve animal performance and to reduce green house gas emissions to adapt to the climate change. In conclusion generally, the research results and applications for reducing pollution caused by animal wastes are now in progress by many effective solutions, however increasing animal performance and product quality in associated with animal production development and environmental protection and improving profits will be also the key issues
