Vertebral columns of female and male breeding rabbits, kept in conventional cages or in a group housing system, were investigated by spot checks anatomically and radiographically in regard to deformations of the vertebral column. It should be proved, whether depending on the housing system and the opportunity of locomotion the male and female rabbits get deformations of the vertebral column. The observations show, that the bucks had no deformations, whereas the does had. It became evident, that frequence and degree of deformation were dependent on the cage size. It provokes deformations by "flat sitting" as well as the systemic hypoplasia of bony tissue caused by deficiency of locomotion. Reproduction provokes deformations of the vertebral column, too, causing alterations in the static-dynamic forces of trunk construction as well as a high need and metabolism of calcium. The causing factors and the relevance of animal protection are discussed.
对饲养在传统笼子或群居系统中的雌性和雄性繁殖兔的脊柱进行了抽查，从解剖学和放射学角度研究脊柱变形情况。需要证明的是，根据饲养系统和运动机会，雄性和雌性兔子是否会出现脊柱变形。观察结果表明，公兔没有变形，而母兔有。很明显，变形的频率和程度取决于笼子的大小。“平坐”以及运动不足导致的骨组织全身性发育不全都会引发变形。繁殖也会引发脊柱变形，导致躯干结构的静动力发生改变，以及对钙的高需求和高代谢。讨论了致病因素和动物保护的相关性。
