A study was conducted to determine the effects of blending different levels of a low-prussic acid cassava flour with extruded full-fat soybeans in diets for growing broiler chickens. The full-fat soybeans contribute oil which increases the energy content of the diet, aids in overcoming the dusty nature of cassava, and provide high-quality protein. One-third, two-thirds, and all of the maize was replaced by cassava in diets with none, 12.5 and 25% extruded full-fat soybeans. Diets were fed in pelleted form to broiler chickens for a 47-day feeding trial. Replacement of one-third of the maize with cassava had no adverse effects on body weight gains in this study with a reduction in weight at higher levels at the conclusion of the study. Feed utilization was reduced more severely than was anticipated. However, growth rate on the higher levels of cassava was reasonably good, indicating that producers might feed these diets for a slightly longer period of time and produce chickens more economically if cassava meal were available at a cost significantly less than that of maize.
开展了一项研究，以确定在生长肉鸡日粮中混合不同水平的低氰木薯粉与挤压全脂大豆的效果。全脂大豆能提供油脂，增加日粮的能量含量，有助于克服木薯的粉尘特性，并提供优质蛋白质。在含有0%、12.5%和25%挤压全脂大豆的日粮中，分别用木薯替代了三分之一、三分之二和全部的玉米。日粮以颗粒形式喂给肉鸡，进行为期47天的饲养试验。在本研究中，用木薯替代三分之一的玉米对体重增加没有不利影响，但在研究结束时，较高替代水平下体重有所下降。饲料利用率的降低比预期更为严重。然而，较高木薯水平下的生长速度相当不错，这表明如果木薯粉的成本显著低于玉米，生产者可能会将这些日粮喂养稍长一段时间，从而更经济地生产肉鸡。
