| 摘 要： | 选取21日龄杜大长断奶仔猪60头，研究日粮中添加1％谷氨酰胺对断奶仔猪免疫功能的影响。断奶10日龄，对照组血清IgG、IgM水平比断奶前有降低趋势，试验组血清IgG、IgM水平无明显下降，对照组和试验组血清IgA水平比断奶前提高20．31％（P〉0．05）、28．13％（P〈0．05），试验组血清IgG和IgM水平分别比对照组高34．67％（P〈0．05）和32．58％（P〈0．05）。断奶20日龄，试验组血清IgA和IgM水平分别比对照组高15．22％（P〈0．05）和30．66％（P〈0．05）。T淋巴细胞增殖分化率分析结果显示，对照组和试验组增殖率分别为16．52％、28．92％，差异显著（P〈0．05）。试验组肠系膜淋巴结的DNA含量较对照组提高9．18％（P〈0．05）。断奶10日龄和断奶20日龄的对照组与试验组间C3、C4水平差异不显著。

| Abstract: | Sixty 21-day weaning piglets were selected to study the effects of 1% glutamine supplementation in diets on the immunity.The results showed:on 10th day postweaning,IgG and IgM concentration of serum in control decreased 21.44%(P>0.05) and 28.23%(P>0.05) than preweaning,IgA in 1.0% Gln group increased 28.13%(P<0.05) than preweaning,IgA,IgG,IgM concentration of serum in Gln group was 6.49%(P>0.05),34.67%(P<0.05) and 32.58%(P<0.05) higher respectively than those in control.Supplementation of Glutamine enhanced IgA,IgG and IgM concentration in serum by 15.22%(P<0.05),2.28%(P>0.05),30.66%(P<0.05) as compared to the control on 20th day post weaning.Glutamine supplementation significantly increased the T lymphocyte proliferation rate by 75.06%(P<0.05) in vitro.The DNA content of mesenteric lymph nodes in Glu group was 9.18%(P<0.05) higher than that in control. |
