皱胃灌注谷蛋白对湖羊瘤胃消化代谢及内分泌的影响

Effect of Abomasum Glutin Infusion on Rumen Digestion Metabolism and Endocrine of Hu sheep

对4头安装有永久性瘤胃和皱胃瘘管的湖羊进行皱胃谷蛋白灌注,观察湖羊瘤胃消化代谢、血浆激素水平以及皱胃食糜中阿片样物质总活性的变化。结果表明,皱胃谷蛋白灌注使湖羊瘤胃总挥发性脂肪酸(TVFA)水平升高17.28%(P<0.05),瘤胃微生物蛋白(MCP)水平升高4.90%,血浆胰岛素水平上升94.94%(P<0.05);皱胃食糜中的阿片样物质总活性增加了29.10%(P<0.01)。皱胃谷蛋白灌注可增加湖羊消化道食糜中阿片样物质总活性,同时改善其瘤胃代谢和内分泌调节。

The research was performed on four Hu sheep with rumen fistula and duodenal fistula. After abomasum glutin infusion, rumen digestion metabolism, TVFA, MCP, and total opioid-like bioactivity of abomasal digesta was analyzed. Results showed that comparing with that of control period, TVFA increased by 17.28%（P〈0.05）, and MCP increased by 4.90%, plasma insulin levels increased by 94.94 % （P〈0.05 ）, and total opioid-like bioactivity increased by 29.10 % （ P〈0.01）. It was conclusion that abomasum glutin infusion could increase total opioid-like bioactivity of abomasal digesta and improve rumen metabolism and endocrine of sheep.
