| 摘 要： | 将微生态制剂添加到肉鸡的饲料中,通过检测肉鸡血清中ND血凝抑制抗体效价、红细胞花环率及免疫器官中T细胞百分数等指标,探讨该制剂对肉鸡体液免疫和细胞免疫的影响。结果表明:在17、26、35、49日龄时,试验组血清中ND血凝抑制抗体效价分别比对照组高8.65%、26.98%、19.83%和46.91%,差异显著(P<0.05);在21日龄,试验组的E-C3bR率和E-ICR率分别比对照组高16.24%和19.93%,均差异显著(P<0.05);10、17日龄时,试验组胸腺T细胞百分数分别比对照组高13.01%(P<0.05)和6.41%(P<0.05),脾脏T细胞百分数分别比对照组高19.40%和9.17%,差异显著(P<0.05)。

| Abstract: | Effects of microecological agent added in feed on humoral immunity and cell-mediated immunity of broiler were studied.Broiler's HI antibody titer of ND in the serum,Erythrocyte-C3b rosette rate (E-C3bRR),Erythrocyte-immune complex rosette rate (E-ICR) etc were detected.The results showed that: At the age of 17,24,35,49 d,the antibody titer of the experiment group increased 8.65 %,26.98 %,19.83 % and 46.91 % respectively(P < 0.05),compared with that of the control group;At the age of 21 d,the E-C3bRR and the E-ICRR of the experiment group were higher 16.24 % and 19.93 %(P < 0.05) than that of the control group.The overall rosette rate of the experiment group was up 17.61 % compared with that of the control group(P < 0.05);At the age of 10 d and 17 d,the percentage of T cells in thymus of the experiment group increased by 13.01 % and 6.41 % respectively(P < 0.05),the percentage of T cells in spleen increased by 19.40 % and 9.17 %(P < 0.05). |
