| 摘 要： | 研究了不同来源淀粉对生长猪门静脉养分净吸收量和生产性能的影响。结果表明：玉米和糙米组成的试验日粮生长猪生长速度最快，显著快于糯米组（P〈0．05），极显著地快于抗性淀粉组（P〈0．01）。生长猪采食抗性淀粉日粮后，葡萄糖和总氮基酸的门静脉净吸收量分别仅为17．84g／100gFI和5．93g／100gFI，显著低于玉米、糙米和糯米组（P〈0．05）。门静脉净吸收氨基酸模式与回肠末端可消化氮基酸模式有很大区别，肠黏膜代谢对氨基酸模式有选择的修饰作用。生长猪增重速度与门静脉总必需氩基酸净吸收量有比较高的相关关系（P=0．0295）。 |

| Abstract: | The influence of different sources of starch on average daily gain and net portal absorption of nutrients by portal vein-drained organs in growing pigs fed different sources of starch has been reported in this study.The daily gain was greater for the pigs fed the starch from corn and brown rice than that of brown stick rice(P<0.05) and resistant starch(P<0.01).The portal vein absorptions of glucose and total amino acid were 17.84 and 5.93 g/100 g feed intake respectively which were lower((P<0.05) than those of the pigs fed the corn,brown rice and brown stick rice.However,all of the portal absorptions of amino acids were much lower than the ileal digestibility of amino acids.There was a closed relationship(P=0.029 5) between average daily gain with net portal absorption of total amino acids in growing pigs |
| Keywords: | net absorption in portal vein performance ileal digestibility growing pigs |
