The Animal Nutrition and Feed Science Research Laboratory aims to provide high quality and safe animal food for human beings, targeting the frontiers of animal nutrition, focusing on solving the major scientific and technological problems and needs of China’s feed resource shortage, livestock product quality and safety, environmental pollution and other industries issues.The research laboratory reveals nutrient digestion, absorption, metabolic pattern and regulation mechanism in animal production, leads the animal nutrition discipline to be among the international advanced ranks, and promotes theoretical innovation and support industrial technology development. Since the establishment of the institute, it has made recognized achievements at home and abroad in research fields, including national survey and research on the distribution of selenium elements, Chinese feed composition and nutritional value sheet, nutritional parameters of pigs and chickens, feeding standards and formulation techniques, regulation of pig and poultry nutritional metabolism and healthy breeding, nutrition and milk quality regulation of dairy cows, methodological innovation of new system for pig and poultry in energy, nutritional value assessment of livestock and poultry feed, etc. It has originality in the establishment of bionic digestive system for nutritional value assessment of monogastric animals, obvious innovation in the molecular mechanism of milk composition formation and its nutritional regulation, establishment of Chinese feed composition and feed nutritional value database, etc. The main research interests include nutritional requirements and metabolic regulation, feed safety and biological potency assessment, nutrition and environment, nutrition and immunity, molecular nutrition and genetics.
