The current article served to provide the most up-to-date information regarding the causes of keel bone fracture. Although elevated and sustained egg production is likely a major contributing factor toward fractures, new information resulting from the development of novel methodologies suggests complementary causes that should be investigated. We identified 4 broad areas that could explain variation and increased fractures independent of or complementing elevated and sustained egg production: the age at first egg, late ossification of the keel, predisposing bone diseases, and inactivity leading to poor bone health. We also specified several topics that future research should target, which include continued efforts to link egg production and bone health, examination of noncommercial aves and traditional breeds, manipulating of age at first egg, a detailed histological and structural analysis of the keel, assessment of prefracture bone condition, and the relationship between individual activity patterns and bone health.
本文旨在提供关于龙骨骨折原因的最新信息。虽然产蛋量增加和持续可能是骨折的主要原因之一，但新的信息来源于新方法的发展，提示了应该调查的补充原因。我们确定了 4 个广泛的领域，可以解释除了产蛋量增加和持续之外或与之互补的变异和增加的骨折：首次产蛋的年龄、龙骨的晚期骨化、易患的骨骼疾病和活动减少导致的骨骼健康状况不佳。我们还具体说明了未来研究应该针对的几个主题，包括继续努力将产蛋量和骨骼健康联系起来，检查非商业禽类和传统品种，操纵首次产蛋的年龄，对龙骨进行详细的组织学和结构分析，评估骨折前的骨骼状况，以及个体活动模式与骨骼健康之间的关系。
