Eficiência da utilização da mandioca (manihot esculenta crantz) E seus subprodutos na alimentação de não ruminantes.

Abstract

In the agricultural scenario, what most raises the cost of production, is the animal feed. The energy component is the second factor that raises the cost of non-ruminant rations higher, leaving behind only the protein component. Corn is the most commonly used ingredient to meet the energy demands of animals. The search for food that can optimize the productive and economic indexes in livestock farming systems has been an essential factor. In view of this situation, numerous alternative foods are being studied in order to guarantee nutritional efficiency, without compromising animal performance and guaranteeing cost reduction. Manihot esculenta Crantz (Manihot esculenta Crantz) is cultivated in practically all Brazilian territory, presents an excellent adaptation, with development even in soils that are more impoverished and with water deficit, besides having an excellent nutritional index. To adopt an alternative food, it is extremely important to obtain knowledge about its chemical composition, even if there is presence of antinutritional factors. The cassava presents energetic indices that makes it an excellent alternative in the substitution by corn.
