Subprodutos da mandioca (Manihot esculenta Crantz) na alimentação de codornas

Abstract

In poultry farming, about 75% of production costs are with poultry feed, it is a poultry sector that has been growing in recent years. In this way, scientific research has been highlighting, in the search for alternative foods, that aim at the total or partial substitution of the main ingredients that affect the formulation of ration, being corn and soybean meal. In view of this, the objective of the literature review was to make a bibliographical survey of the utilization of by - products obtained from cassava, demonstrating the importance and its benefits, levels of inclusion recommended by authors and their applicability in quail feeding. The manioc (Manihot esculenta, Crantz) is cultivated practically throughout the Brazilian territory, having good adaptation, besides good nutritional quality and can be used in animal feed, with its main residues and byproducts originated from the processing (root rasp, leaves, hay of the aerial part, trimming flour and silage) and can be supplied to the animals in various forms. To make coturniculture feasible, it is necessary to know better the potential of some alternative food specific to quails, and it is important to observe the antinutritional factors. Thus, it is important to emphasize the need for continuity of studies in the area of nutrition, since there is however little literature on the subject that demonstrates the benefits of the use of cassava by-products in quail feeding and can be used as alternative food on poultry diets, offering extra income to small and medium producers and / or reducing costs without damaging animal productivity.
