Insufficient supply, high prices and competition with the human food and biofuel industries means there is a continuous demand for alternative energy sources for poultry. As a result, cassava is becoming an increasingly important ingredient in poultry diets, largely due to its high availability. Efficient use of cassava products has been shown to reduce feed costs of poultry production. The utilisation of cassava is, however, limited by a number of factors, including its high fibre and low energy content and the presence of anti-nutritional factors, primarily hydrocyanic acid (HCN). With correct processing the inclusion level of cassava in poultry diets could be increased. Extensive research has been conducted on cassava products for poultry, but there is still a lack of consistency amongst the measured nutritive values for cassava and its products, hence variation exists in results from poultry studies. This paper reviews the nutrient composition of cassava products and its value as an alternative energy source in poultry diets.
供应不足、价格高昂以及与人类食品和生物燃料行业的竞争意味着对家禽替代能源的需求持续存在。因此，木薯正成为家禽日粮中越来越重要的成分，这主要归功于其高可得性。事实证明，有效利用木薯产品可降低家禽生产的饲料成本。然而，木薯的利用受到多种因素的限制，包括其高纤维和低能量含量以及抗营养因子的存在，主要是氢氰酸（HCN）。通过正确加工，可以提高木薯在家禽日粮中的添加水平。针对家禽木薯产品已开展了广泛研究，但木薯及其产品的测定营养价值仍缺乏一致性，因此家禽研究结果存在差异。本文综述了木薯产品的营养成分及其在家禽日粮中作为替代能源的价值。
