利用体外培养法建立饲料营养成分与瘤胃丙酸产量的回归模型
The development of mathematical models for estimating the propionic acid yields in the rumen from some feed nutrients parameters by in vitro technique
【摘要】 根据美国康乃尔净碳水化合物和蛋白质体系 (CNCPS) ,分析测定了 4类 2 4种饲料的营养成分 ,利用体外批次培养技术测定了它们在体外培养一定时间后的丙酸产量 ,并由此建立了饲料中产丙酸的营养成分和瘤胃丙酸产量的回归方程
【Abstract】 The feed nutrients parameters of 4 kinds of 24 individual feeds were analysed in the experiments based on the feed protein and carbohydrate fractionation proposed by CNCPS and the propionic yields were determined by in vitro technique. The mathematical models for estimating the propionic acid yields in the rumen from some feed nutrients parameters were developed.
