摘　　要：作者针对肉仔鸡营养需要量、饲料效价评定及配方设计技术等方面,概述了当前的进展与趋势。文献表明,肉鸡饲养阶段的划分更科学,大部分从3个阶段过渡到4个阶段;营养需要规格呈现多元化趋势,主要考虑与肉鸡品种、环境、追求的生产目标及饲料原料本身的评价体系等结合起来;日粮配方优化技术本身是不变的,但引入配方模型的系数矩阵若带入饲料养分的标准差即变异,将会明显提高配方养分实际达成的概率。如果用标准化回肠可消化率氨基酸配制日粮,一般能提高对肉鸡生产性能的预测水平。上述研究结果与思想将为中国开发新一代肉鸡饲养营养专家系统提供科学依据。The advances on nutrient requirements, feedstuff evaluation and formulation techniques of broiler are reviewed in this paper. It showed that feeding phases decision is more scientific from three to four phases; nutrient requirement specifications is presenting diversified trend of development, which are referred to be combined with the broiler breeds, environment, production goal and the evaluation systems of the feedstuff itself etc; secondly, formulation optimization technology itself is relative invariable, but if the coefficients matrix of formulation model is integrated from the standard deviation of the nutrients of used feedstuff, it wilt evidently enhance the true probability for goal nutrients to reach. The third, performance prediction a bout broiler is improved when diets are formulated on the basis of standardized ileal amino acid digestibility. The results and thought can provide the scientific basis for developing the new generation expert system of broiler feeding and nutrition.
