Abstract

The bionic digestion technology based on in vitro enzymatic digestion method has been widely used to evaluate the nutritional values of feed for pigs in Denmark, Netherlands, France and other developed countries. Also, the nutritive value of feedstuff determined with the bionic digestion method has been the key contribution to establish their national feeding standard. However, this technology is still not differ from the traditional in vitro enzymatic digestion method, in which the pancreatin is used to prepare the simulated digestive fluids, thus its hydrolytic activity can not be repeatable, moreover, complete manual operation progresses the in vitro digestion with the simple instruments such as flask and shaking incubator. Therefore, the biological background and standardization for preparation of simulated digestive fluid and developing a specific instrument to simulate the procedure of in vivo digestion are always the key points and the difficult to innovate the method of in vitro enzymatic digestion. This review focuses on the advance on the development of simulated digestion technology for pig and also presents the experiment results studied at the China's State Key Laboratory of Animal Nutrition in this field.
