As the world's largest dairy country, New Zealand, Holland and the United States show their development in common. The degree of organization brings cost savings and improves technological progress. The vertical chain of dairy industry is closely related, and by mutual holding, dairy farmers, dairy cooperatives and dairy products processing enterprises form a chain of interest to ensure the long-term development. Every aspect of the industry chain have strict quality supervision standard, third party inspection and evaluation system to ensure the implementation of standard. Compared with the rapid development of Chinese dairy industry, it still exists problems, such as unreasonable product structure, high production costs, poor supervision and so on. Therefore, we should focus on the establishment of selection mechanism in dairy cows, promote dairy farming scale and the development of dairy cooperatives, strengthen the quality supervision of the dairy industry and improve the social service system.
