摘　　要：　大米加工副产品大米粉长期以来被添加到米糠中利用,显著降低了其利用率。本试验用三头施以回直肠吻合术猪,采用单因子设计,以大米粉为半纯合日粮,无氮日粮由醋酸纤维素提供粗纤维来测定内源值,测定了大米粉的猪回肠末端氨基酸表观消化率和真消化率。大米粉的回肠末端氨基酸的表观消化率的平均值为76.20%,真消化率的平均值为85.86%。这些数据可为我国氨基酸消化率数据库提供参考,并且可作为以可消化氨基酸为基础配制日粮时的依据。Rice flour-the by-product of rice processon is utilized through adding to rice bran in long period, which decease the utilization of rice flour significantly. Endogenous values were determined with three swine with ileo-rectal anastomoses, adopting one-factor-design. Rice flour were added to semi-purified diet, and nitrogen-free diet were provided by cellulose acetate. The mena value of apparent ileal amino acid digestibility of rice flour is 76.20%, the mean value of true digestibility is 85.86%. These data are not only the reference for my country amino acid digestibility data-base, also the foundation for make up diet adopting digestible amino acid.
