Abstract

The oral administration of glucose or dietary glucose reduces fasting plasma mannose concentrations in mammals. On the other hand, there have been no reports on plasma mannose levels in birds. We have analysed chicken plasma mannose and glucose by an original high-performance liquid chromatography (HPLC) method, together with plasma non-esterified fatty acid (NEFA) concentrations in chickens. 2. Plasma glucose concentrations of chickens did not differ among three different age groups (0, 18 and 150 d). However, the plasma mannose concentrations of chicks at the age of 0 d were higher than those of chickens at the ages of 18 and 150 d. 3. At the age of 18 and 150 d, plasma glucose concentrations were elevated and plasma mannose and NEFA concentrations were decreased after regular feeding, compared to fasting levels.

摘要

口服葡萄糖或膳食葡萄糖可降低哺乳动物空腹血浆甘露糖浓度。另一方面，关于鸟类血浆甘露糖水平尚无相关报道。我们采用原创的高效液相色谱（HPLC）法分析了鸡血浆中的甘露糖和葡萄糖，并测定了鸡血浆中非酯化脂肪酸（NEFA）的浓度。2. 鸡的血浆葡萄糖浓度在三个不同年龄组（0、18和150日龄）之间没有差异。然而，0日龄雏鸡的血浆甘露糖浓度高于18日龄和150日龄的鸡。3. 在18日龄和150日龄时，与空腹水平相比，正常喂食后血浆葡萄糖浓度升高，血浆甘露糖和NEFA浓度降低。
