(1) How to develop dairy production, reduce its environmental pollution as much as possible, effectively control the occurrence of malignant infectious diseases, and reduce or eliminate hidden dangers such as drug residues in dairy products is a problem that people pay more and more attention to and urgently need to solve. Therefore, the development of healthy dairy farming is of great practical significance for ensuring the safety of milk and beef, protecting the health and life safety of consumers and promoting the export of products.
(2) Healthy farming is a high-quality, safe, efficient, organic and pollution-free sustainable farming, and it is a modern farming that pays equal attention to quantity, quality and ecological benefits. Healthy farming can change the low production efficiency of traditional dairy farming and neglect the control of drug residues in milk and beef and the environment of dairy farming, thus promoting the healthy development of dairy farming in China, improving the productivity of dairy cows, and promoting farmers' employment and income increase.
(3) Healthy farming is beneficial to reduce the environmental pollution caused by dairy farming. In recent years, the number of dairy cows in China has increased rapidly, and most of them adopt the mode of house feeding (intensive farming). Many rural dairy farming communities or dairy farms lack necessary isolation measures, and people and cows live together. Cow manure, sewage, harmful gases and stench have become a major hidden danger of rural public health and environmental pollution. The healthy breeding of dairy cows can improve the utilization efficiency of feed, reduce environmental pollution, realize the harmony between man and nature, and make the dairy industry develop steadily.
