To study the substitution technology of feed antibiotics (such as medicinal plants and extracts, antibacterial peptides, etc.). ), on the premise of ensuring efficient animal production, using antibiotic-free green feed to produce safe animal products. To study the molecular mechanism, metabolic pathway and influencing factors affecting the formation of quality traits of pigs and chickens, and to produce high-quality livestock products through effective nutritional regulation.

2. Nutrition and feed of monogastric animals

On the basis of focusing on the research trends, research hotspots, research progress and industry development trends at home and abroad in this field and related fields, this research direction is mainly engaged in the nutritional needs of monogastric animals such as pigs and chickens, as well as the development and safety evaluation of nutrition and feed, nutritional physiology, nutrition regulation, nutrition and immunity, nutrition and environment, new feed and feed additives related to monogastric animals. Through the study of relevant thematic theories, experimental design of dissertations, project implementation and thesis writing, senior professionals engaged in the research and production of monogastric animal nutrition and feed are trained.

3. Nutrition and feed for ruminants

Combined with the dairy farming conditions in China, the problems of low yield, poor milk quality and many nutritional metabolic diseases in dairy production in China were solved by using the guiding ideology of systematic and integrated nutritional regulation, through the evaluation of nutritional parameters and feed nutritional value of dairy cows, the production and scientific utilization technology of high-quality roughage, the nutritional balance technology of diet, the efficient and refined feeding management and nutritional detection technology of dairy cows, and the prospective study of nutritional metabolic regulation of dairy cows. Through the research in this direction, the standardized technical specifications for dairy farming suitable for different regions or different farming modes will be finally formed.

4. Animal behavior welfare and environment

This direction mainly studies the mechanism of abnormal behavior of livestock and poultry under intensive production conditions, the factors affecting animal welfare, and explores new technologies for livestock and poultry breeding that are beneficial to the health and production performance improvement.

5. Animal molecular nutrition and feed biotechnology

The research direction is mainly engaged in the interaction between nutrients and genes (including the interaction between nutrients and genes, the interaction between nutrients and genes, and the interaction between genes and genes) and the law and mechanism of its influence on the health of the body. Modern biotechnology is used to develop new feed resources, improve the nutritional value and conversion rate of feed, reduce anti-nutritional factors and toxins in feed, reduce production costs and save feed.

6. Information technology of feed and livestock products

In this paper, the computer management of data and the digital monitoring system of safety and quality in feed processing and animal products production are studied. Through the hazard assessment of each link, measure and component in the process of feed-breeding-livestock products-consumers, as well as the analysis and inspection of key control points, an operable standard system is formulated for the whole production chain, so that raw material supply, processing and production, packaging and transportation, sales and consumption can be carried out under unified operating standards, thus ensuring the safety of livestock products.
