饲料营养成分与瘤胃丙酸产量回归模型
The Development of Mathematical Model for Estimating the Propionic Acid Yield in Rumen from Some Feed Nutrients Parameters
【摘要】 本试验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24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 experiments studied some feed nutrients parameters of 4 kinds of 24 individual feeds based on the feed protein and carbohydrate fractionation proposed by CNCPS, determined the propionic yields by in vitro technique, and developed the mathematical models for estimating the propionic acid yields in the rumen from some feed nutrients parameters.
