摘　　要：以苜蓿草粉、黑麦草粉和混合草粉（质量比为1：1）为底物，接种鹅盲肠食糜滤液进行体外培养。试验结果为：培养液pH值在0—3h下降到6．9左右，后逐渐趋于稳定；苜蓿草粉ADF、NDF和半纤维素的消失率分别为1．15％，1．18％，-0．19％；黑麦草粉三者的消失率分别为1．45％，9．05％，3．07％；而混合草粉三者的消失率分别为15．72％，13．2％，9．87％。与单一草粉的ADF、NDF和半纤维素的消失率都有显著差异（P〈0．05）。结果表明：在体外条件下，鹅盲肠微生物对不同来源的ADF、NDF和半纤维素有一定的利用能力，且对混合草粉ADF、NDF和半纤维素的利用能力强于单一草粉。In order to study the digestion of fibrous materials ADF and NDF, the alfalfa, ryegrass and their powder mixture were chosen as the substrates, and mixed with the cecum chyme filtrate for fermentation, pH value declined to 6.9 during first three hours fermentation, and then came to be stable. The degestibilities of ADF, NDF and hemicellulose in alfalfa were 1.15% , 1.18% amd -O. 19% , respectively; 1.45%, 9.05% and 3.07% in ryegrass; 15.72%, 13.2% and 9. 87% in the mixed power, which were significantly different from those in the single one. The results showed that the microorganisms in goose cecum could decompose the grass fiber from different substrates. The digestive ability of the mixed powder was higher than those of the single powder.
