The intestinal health represents great importance to the overall health status of production animals, including fish. The intestinal tract is directly responsible for the assimilation of nutrients, but it is also composed of a complex microbiota, comprising beneficial micro-organisms and pathogens to interact. Negative impacts on gut health ally to the intrinsic problems of the intensive cultivation system may reflect lower productivity and decrease resistance of fish. In this project, we intend to evaluate the beneficial effects of diets with two herbal medicines on intestinal health of fish. Will be examined: morphology of the gut, microbiota and antioxidant molecules associated with intestinal health, and finally the resistant bacteria. (AU)
