【摘要】：为探讨下丘脑-垂体-甲状腺轴对斗鸡攻击行为的影响,采用免疫组织化学法对比分析不同生长阶段吐鲁番斗鸡与新罗曼蛋鸡下丘脑中促甲状腺激素释放激素(TRH)神经元的数量,结合酶联免疫吸附法测定两品种成年公鸡攻击行为表现前、中、后各时期血清中TRH和甲状腺激素(TH)的含量。结果表明两品种鸡的TRH在下丘脑中的阳性细胞数随着周龄增加而减少,整体上吐鲁番斗鸡TRH的阳性细胞数高于新罗曼蛋鸡,公鸡高于母鸡;斗鸡和新罗曼蛋鸡血清中TRH的含量随着周龄增加逐渐上升,TH呈下降趋势,且吐鲁番斗公鸡的TRH和TH含量较高,打斗时间的持续性也比新罗曼蛋公鸡长。因此,吐鲁番斗鸡较强的攻击行为可能与这两种激素含量偏高有关。
[Abstract]:In order to investigate the effect of hypothalamus-pituitary-thyroid axis on aggressive behavior of cocks, the number of thyrotropin-releasing hormone (TRH) neurons in the hypothalamus of Turfan and Neo-Roman layers at different growth stages was analyzed by immunohistochemical method. The levels of TRH and thyroid hormone (th) in serum of two adult cocks before, during and after attack behavior were determined by enzyme linked immunosorbent assay (Elisa). The results showed that the number of TRH positive cells in the hypothalamus of the two breeds of chickens decreased with the increase of age, and the total number of TRH positive cells of Turpan cocks was higher than that of Neo-Roman layers, and that of male hens was higher than that of hens. The content of TRH in the serum of cocks and Neo-Roman laying hens increased gradually with the increase of age, and the TRH and th contents of Turpan cock were higher, and the duration of fighting was longer than that of Neo-Roman egg cock. Therefore, the aggressive behavior of Turpan cockfighting may be related to the high content of these two hormones.
