摘要 本研究以快速测定代谢能的方法为对照,按 L_9(3~4)正交试验设计,对用猪小肠液离体消化测定向日葵仁饼、粕的离体消化能的条件进行了选优,用优选的条件对46个向日葵仁饼、粕的 IVDE 进行了测定。结果表明:pH=7.6、时间为4小时、温度为39℃时,测定的向日葵仁饼、粕的 IVDE 与实测的表观代谢能(AME)符合度较好.向日葵仁饼的 IVDE 与 AME 呈强相关关系(r=0.96),向日葵仁粕的 IVDE 与 AME 亦呈强相关关系(r=0.91). The best condition for estimating In vitro digestible energy(IVDE)of in vitro incubation with peps in-porcine intestinal fluid was selected in L_9(3~4)orthogonal exp- erimental design.The IVDE and AME of 46 groups sunflower cake and meal were deter- mined by modified in vitro method rapid biological method,The results showed that the IVDE and AME of sunflower cake and meal estimated only had slight difference, under such a condition as when the pH of the incubation remained 7.6,the time was limited to 4 hours,and the tempera- ture remained 39℃.Furthermore,the results showed for sunflower cake there were si- gnificant correlative relationship between IVDE and the AME(r=0,961),for sunflow- er meal there were significant correla- tive relationship between the IVDE and the AME(r=0.91).
