广西崇左野生猕猴粪便甲状腺激素水平的季节差异
|
Abstract:
动物体内甲状腺激素水平在生理评估具有重要作用，常用来表征动物能量代谢水平。本研究采用酶联免疫法对广西崇左野生猕猴(Macaca mulatta)粪便甲状腺激素的含量进行测定，并分析不同季节的含量差异。结果表明：崇左猕猴粪便甲状腺激素T3在12.54~25.97 ng/g之间，平均值为17.24 ± 3.40 ng/g。T4含量在26.21~54.53 ng/g之间，平均值为37.51 ± 8.22 ng/g。夏季猕猴粪便甲状腺T3平均含量为19.68 ± 3.31 ng/g，冬季为15.14 ± 1.63 ng/g。夏季猕猴粪便甲状腺T4平均含量为43.23 ± 7.87 ng/g，冬季32.55 ± 4.51 ng/g。分析发现，崇左野生猕猴甲状腺激素T3 (t = ？4.705, df = 26, P < 0.001)和T4 (t = ？4.482, df = 26, P < 0.001)含量在夏季均高于冬季。这可能与猴群夏季时期采食更多的果实等高质量食物有关。本研究评估了石山地区猕猴的能量代谢水平，为保护石山灵长动物提供了重要的生理数据。
The level of thyroid hormone plays an important role in physiological evaluation of animals and has been commonly used to characterize the energy metabolism level of animals. This study used enzyme-linked immunosorbent assay to determine the content of thyroid hormones in the feces of wild macaques (Macaca mulatta) in Chongzuo, and analyzed the differences in content in different seasons. The results showed that the fecal thyroid hormone T3 in Chongzuo macaques ranged from 12.54 to 25.97 ng/g, with an average value of 17.24 ± 3.40 ng/g. The T4 content ranges from 26.21 to 54.53 ng/g, with an average of 37.51 ± 8.22 ng/g. The average thyroid T3 content in macaque feces during summer is 19.68 ± 3.31 ng/g, and during winter it is 15.14 ± 1.63 ng/g. The average thyroid T4 content in macaque feces during summer is 43.23 ± 7.87 ng/g, and during winter it is 32.55 ± 4.51 ng/g. Analysis found that the levels of thyroid hormones T3 (t= -4.705, df = 26, P < 0.001) and T4 (t = ？4.482, df = 26, P < 0.001) in wild macaques in Chongzuo were higher in summer than in winter. This study evaluated the energy metabolism level of macaques in limestone, providing important physiological data for the protection of primates in limestone forest.
