摘要： 为探讨冬虫夏草（Cordyceps sinensis）菌丝体对獭兔免疫功能的影响，以冬虫夏草菌丝体发酵液为添加剂，对母獭兔及其断乳幼仔进行喂饲试验。母兔喂饲试验：选取80 只体质量相近且刚配种的同期怀孕母兔，随机分为2组，试验组喂饲改良日粮（基础日粮中添加2%冬虫夏草菌丝体发酵液），对照组喂基础日粮。仔兔喂饲试验：随机选取母兔喂饲试验组所产断奶仔兔10 只，喂饲改良日粮（试验组Ⅰ）；选取母兔喂饲试验的对照组所产断奶仔兔20只，随机分为2 组，一组喂饲改良日粮（试验组Ⅱ），另一组喂饲基础日粮（对照组）。母兔喂饲试验表明：相对于对照组，试验组母兔所产仔兔存活率提高了28 个百分点（P＜0.01），而整窝死亡率降低了33.5 个百分点（P＜0.05）；试验组的哺乳期母兔免疫球蛋白A（immunoglobulin A, IgA）含量也显著高于对照组（P＜0.01）。仔兔喂饲试验表明：试验组Ⅰ仔兔蚓突指数显著高于对照组，而试验组Ⅰ与试验组Ⅱ间的差异未达显著水平（P＞0.05）；试验组Ⅰ和试验组Ⅱ的T淋巴细胞阳性率均显著高于对照组（P＜0.01）。综上可见，对孕期及哺乳期母兔喂饲添加冬虫夏草菌丝体发酵液的改良日粮，有利于降低仔兔死亡率，提高母兔免疫因子IgA 含量，对断乳幼兔喂饲改良日粮有利于提高免疫器官质量和T淋巴细胞阳性率，从而增强獭兔的免疫功能。

Abstract: In order to investigate the effect of Cordyceps sinensis mycelium on the immune function of Rex Rabl rabbit, feeding experiments were carried out on mother Rex Rabl rabbits and their weaning young rabbits with the additive of zymotic fluid of C. sinensis mycelium. In the experiment of mother rabbit, 80 pregnant Rex Rabl rabbits of similar body mass were randomly divided into two groups. Between them, the control group was fed with basal diet and the treatment group with improved diet (added 2% zymotic fluid of C. sinensis mycelium based on basal diet). In the experiment of weaned young rabbit, the treatment groupⅠwith 10 offsprings from the previous treatment group and the treatment group Ⅱ with 10 offsprings from the previous control group were both fed with improved diets, and the control group with 10 offsprings from the previous control group was fed with basal diet. The results of mother rabbit experiment showed that the survival rate of young rabbits of the treatment group was significantly higher than that of the control group by 28 percentage points (P＜0.01), and the overall death rate of the treatment group was significantly lower than that of the control group by 33.5 percentage points (P＜0.05). Moreover, the IgAcontent of lactating female rabbits in the treatment group was significantly higher than that in the control group (P＜0.01). The results of weaning young rabbit experiment indicated that the rabbit appendix index of the treatment groupⅠwas significantly higher than that of the control group, and the positive rates of T lymphocytes in the treatment groupⅠand Ⅱ were significantly enhanced in comparison to that in the control group (P＜0.01). In conclusion, feeding the mother rabbits in pregnancy
and lactation with improved diet containing zymotic fluid of C. sinensis mycelium is helpful to reduce the infant rabbit mortality and increase the IgA content of mother rabbit. Feeding the weaning rabbits with improved diet is also beneficial to enhance immune organ mass and positive rate of T lymphocyte of young rabbits. This study indicates that the immune function and disease-resistant ability of Rex Rabl rabbits can be enhanced by adding zymotic fluid of C. sinensis mycelium in basal diet.
