[Production of cassava whole meal (N. esculenta Crantz) to prepare a feed for growing chicks. II. Evaluation of cassava whole meal in growing chicks].
About 50% of the raw materials used for poultry feeds are constituted of sorghum as a energy source. The purpose of this work was to evaluate the nutritional quality of a cassava whole meal (CWF: 61.2% and 38.8% of root and leaf flours, respectively) for growing chicks. The sorghum was partially substituted from a basal diet by 15, 30 and 45% of CWF. Four diets based of sorghum, soybean meal and CWF were formulated. Levels of 0.0, 8.6, 16.4 and 23.7% of CWF were included in the diets. White Vantress chicks (96) were used in the nutritional experiment during 28 days. Each treatment was assayed with 24 chicks. The diet containing 23.7% of CWF showed the lower weight gain and feed efficiency (p < 0.05) as compared with the other diets, and the liver/ bird weight relation increased directly with the increment of CWF.
