摘要 本研究旨在探讨利用压力传感器产气技术(RPT),用改进的组合效应多项指标综合指数(MFAEI)对反刍动物稻草基础日粮添补不同比例苜蓿的组合效应进行动态的、综合的整体评定.稻草(RS)与苜蓿(AH)分别以0%(AH0)、20%(AH20)、40%(AH40)、60%(AH60)、80%(AH80)与100%(AH100)的比例混合进行体外批次培养,将12 h、24h与48h的产气量(GP)、总挥发性脂肪酸(VFAs)与微生物氮(MN)用经改进的MFAEI进行了多时间点、多指标的整体评定.结果表明:采用RPT,应用经改进的MFAEI能较好地量化反刍动物饲料之间的组合效应,直接进行组合效应的大小评定;反刍动物稻草基础日粮以添补40%～60%的苜蓿效果较好.
