Species specifics in gastro-intestinal function

A large number of investigators have been carried out in different species to elucidate the characteristics in gastro-intestinal functions. It is very interesting article to compare these characteristics in various species having different feeding behaviour. In this lecture, findings by mainly my own studies will be described about following three sections. 1. Postnatal developments in neonate and milk The postnatal ontogeny of the mammalian gut is reflected in changes in milk composition and in the nutrient and nonnutrient requirements and growth rate of the newborn. One of the most characteristic developments in the gastro-intestinal tract is cessation of intestinal macro
