摘要: 从组织学角度探讨添喂绞股蓝对广西三黄鸡胸腺增龄性的作用,在饲料中添加0.5%绞股蓝粉,考察1、14、28、56、90、120、150日龄胸腺重、胸腺指数、皮髓面积比、胸腺小体数量及面积。结果表明,随日龄增加,胸腺重升高,胸腺指数先升后降,添喂绞股蓝在一定程度上提高胸腺重及胸腺指数;随日龄增加,胸腺皮髓比降低,120日龄时添喂组皮髓比显著大于不添喂组(P<0.05);不添喂组和添喂组的胸腺小体数量分别在56日龄和90日龄前增多,之后呈波浪式下降,在28、90、120日龄时,添喂组胸腺小体数量显著多于不添喂组(P<0.05);不添喂组和添喂组的胸腺小体面积在120日龄前增大,之后减小,不添喂组和添喂组各日龄差异不显著。表明在饲料中添加0.5%绞股蓝粉能够延长广西三黄鸡胸腺成熟时间、推迟胸腺退化,提高胸腺功能。

Abstract: From the histological point of view, the effect of adding Gynostemma pentaphyllum on the thymus aging of Guangxi Sanhuang chickens was studied. 0.5% G. pentaphyllum powder was added to the feed, and the thymus weight, thymus index, cortex-medium area ratio, number and area of thymus bodies were examined at 1, 14, 28, 56, 90, 120, and 150 d. The results showed that with increasing age, the thymus weight increased, and the thymus index rose first and then decreased. The addition of G. pentaphyllum increased the thymus weight and thymus index to a certain extent. With the increase of the age, the thymic cortex-medullar ratio decreased, and at 120 d, the cortex-medullar ratio of the fed group was significantly greater than that of the non-added group(P<0.05). The number of thymus bodies in the non-feeding group and the feeding group increased before 56 and 90 d, respectively, and then decreased in a wave pattern. At 28, 90, and 120 d, the number of thymus bodies in the fed group was significantly more than that in the non-fed group(P<0.05). The thymus body area of the non-feeding group and the feeding group increased before 120 d, and then decreased. The day-to-day differences of the non-feeding group and the feeding group were not significant. Adding G. pentaphyllum powder in the feed can prolong the thymus maturation time, delay the thymus degradation, and improve the thymus function.
