Nutritional characteristics of forage species in the silvipastures of multiple strata in Chiapas, Mexico

摘要

Recently, the silvipasture system investigations have assumed a more important paper due to the necessity of productive design systems that are in harmony with the enviroment Under this context, cattle improvement with the use of wood and herbaceous plants associated with pastures is a strategy that should be exploited, especialy in world tropics, due to its great vegetable biodiversities. In this respect, in the central valley of Chiapas, Mexico, exists a wide empirical knowledge in the producers asto the great diversity of vegetable forage species; but they know little of their nutritional quality. This apparent situation the potential of the region to develop efficient strategies for animal production, but this great diversity has not been tested in a systematic form. For this it is neccesary to recognize amd to generate bigger knowledge in this respect.
