When people are satisfied with the quantity of animal food, they put forward higher and higher requirements for the quality of animal products, which is normal, reasonable and impeccable. Now we emphasize healthy farming and healthy food because there are many unhealthy farming phenomena and animal food without health guarantee in real life. For example, the frequent occurrence of infectious diseases, the abuse of antibiotics, chemicals and hormones, and the addition of prohibited substances not only seriously affect the health of animals, but also pose a great threat to human health! The pressure of high-density breeding and bad feeding environment greatly reduces the immunity of animals themselves. In order to control the occurrence of diseases, a large number of drugs are used, which makes animal production fall into a vicious circle of harsh environment, frequent diseases, drug abuse, drug residues and environmental pollution! The release of animal manure and decomposition products in nature has polluted the atmosphere, soil and water, destroyed the ecological environment on which human beings depend, and left incalculable future troubles for future generations!
Therefore, being kind to the ecosystem on which we live and caring about the health of all kinds of animals we breed have aroused great concern in aquaculture and even the whole society. With the adjustment of China's agricultural industrialization structure, aquaculture has become a pillar industry of rural economy. How to ensure the health of livestock and poultry, how to face the challenge of modernization to traditional farming methods, and how to make livestock products gradually meet the requirements of pollution-free food, green food and organic food are major issues facing animal husbandry today. Under this background, a new breeding concept-healthy breeding was put forward from the perspectives of animal nutrition, environmental hygiene of livestock, animal immunology, feeding and processing of livestock products. That is to say, increase the investment in aquaculture science and technology, provide full-price safe nutritious feed and comfortable environment as a means, protect animal health by improving the internal physique and immune function of animals, protect people's health from the source of food to the maximum extent, make aquaculture enter the track of sustainable development, fundamentally improve the economic benefits of aquaculture producers, and run through the whole process of feed processing and production, animal breeding, environmental protection discharge and livestock product processing with the concept of health.
