本试验旨在研究饲粮外源代谢葡萄糖(MG)水平对断奶仔猪门静脉回流组织(PDV)氨基酸利用量的影响。选择20头健康状况良好、体重在7.74 kg左右的25日龄杜×长×大三元杂交断奶仔猪,分为4个处理组,每组5个重复,给每头猪的门静脉、颈动脉和肠系膜静脉安装血管插管,并安装'T'型回肠瘘管。待仔猪术后恢复正常后,4组分别饲喂MG水平为22.82%、26.59%、36.37%、42.41%的等能、等氮的玉米-豆粕型饲粮,每种饲粮添加0.1%的二氧化钛(TiO2)作外源指示剂。术后3 d,从肠系膜静脉持续灌注对氨基马尿酸(PAH),并从门静脉和颈动脉采血,并且在回肠段收集食糜。结果表明:仔猪PDV氨基酸利用量随着MG水平增加呈先上升后下...

The aim of this research was to study the effects of different exogenous metabolic glucose levels to the utilization of amino acids form weaned piglet’s Portal-drained viscera. 20 hybrid weaned piglets(25-day-old and average body weight of 7.74 kg) were randomly divided into 4 treatment groups, with 5 replicates per treatment and 1 pig per replicate. The vascular fistulas was installed on the portal vein, carotid artery and mesenteric of each pig respectively,and the T-Cannula was implanted into the terminal ileum. After the piglets returned t...
