Due to the decline in the population and the difficulty of in situ conservation, several anuran species are being reared in captivity. In this study, we identified physiological and morphological differences between farm-bred and wild frogs. Nine different serum components were used as indicators of osmotic pressure, homeostatic state, organ function, and nutritional status of farm-bred frogs and wild frogs, while radiographic techniques were used to visualize differences in bone mineral density and body composition ratio. Additionally, X-ray skeletal images were used for morphological analysis to estimate differences in locomotory performance between the two groups. Wild frogs harbor traits that aid in better locomotory performance than farm-bred frogs. They also have a relatively lower fat content ratio and higher calcium and phosphorus serum levels than farm-bred frogs, suggesting a difference in nutritional status. However, hepatic stress was higher in wild frogs than in farm-bred frogs. Veterinary clinical examinations allow for the identification of differences in nutritional and morphological conditions between farm-bred and wild frogs. Determining the health of animals can help improve their living conditions, eliminate conditions that can negatively affect them, and effectively manage them on farms, in zoos, and at ex situ conservation institutes.
由于种群数量下降以及原地保护的困难,几种无尾目物种正在圈养环境中饲养。在本研究中,我们确定了养殖青蛙和野生青蛙在生理和形态上的差异。使用九种不同的血清成分作为养殖青蛙和野生青蛙渗透压、内稳态、器官功能和营养状况的指标,同时使用放射技术来观察骨矿物质密度和身体组成比例的差异。此外,利用X射线骨骼图像进行形态分析,以估计两组之间运动性能的差异。野生青蛙具有比养殖青蛙更好的运动性能的特征。它们的脂肪含量比例也相对较低,血清钙和磷水平高于养殖青蛙,这表明营养状况存在差异。然而,野生青蛙的肝脏应激高于养殖青蛙。兽医临床检查有助于识别养殖青蛙和野生青蛙在营养和形态状况上的差异。确定动物的健康状况有助于改善它们的生活条件,消除可能对它们产生负面影响的状况,并在农场、动物园和异地保护机构中对它们进行有效管理。
