Avaliação da mandioca (Manihot esculenta Crantz) e subprodutos na alimentação de codornas (Coturnix Japonica)

Abstract

Three experiments were conducted in the Campus II from the Universidade Estadual de Alagoas in Santana do Ipanema AL. The general objective of this work was to evaluate the cassava's potential (Manihot esculenta Crantz) and some of the by-products in quails' feeding.The first experiment was conducted to determine the chemical composition and values of apparent metabolizable energy (EMA); and apparent metabolizable energy corrected by nitrogen balance (AMEn), the apparent metabolism coefficient of gross energy (CMAEB) of cassava and its by-products, using the total excreta collection method and 20-day-old male quails. The values of EMA, EMAn and CMAEB were (3305,9; 3058,28 and 80,54); (2525,02; 2452,87 and 78,90); (1626,41; 1372, 91 and 53, 18) and (1523,98; 1448,28 and 51, 94) for cassava root, manipueira molasses, hay of cassava leaf and a final third of the plant,respectively. In the second experiment, the effects of the inclusion of different levels (0, 3, 6,9, 12%) of the hay of cassava leaf about the zootechnics performance of male quails createdup to 42 days. The effects of inclusion of the hay of cassava leaf weren't observed up to the level of 12% for the total period of creating (8 to 42 days), as well as were not found differences between the treatments for the parameter of carcass, being only affected the offals. The third experiment was conducted to evaluate the zoothechinics performance of quails for the meat's production, using a diet with different levels of integral cassava flour (0,8, 16, 24 and 32%). Statistics of variations of weight gain, consuming of ration and the conversion of feeding weren't observed in the period studied, can the cassava root be included in diets for quail up to the level of 32%.
