摘要: 骨密度是衡量骨骼强度的一个重要指标,广泛应用于人和动物骨骼健康的评估。近年来动物肢蹄问题给养殖业带来了一定程度的经济损失,尤其是养猪业。骨密度水平的测定将有助于建立养殖场动物淘汰的预警标准,及时治疗或淘汰肢蹄疾病动物,降低养殖成本,提高养殖场生产效益。鉴于骨密度水平可以预测肢蹄问题的发生,动物骨密度的活体测定将对动物生产性能和利用年限有很大提升。哺乳动物体内骨密度水平受胎次、妊娠、哺乳及激素的影响,哺乳动物骨密度活体测定可以及时反映动物骨骼健康状况,从而提升动物体内骨密度水平,改善动物骨骼健康状况。作者综述了近几年国内外对骨密度的研究进展,包括几种常用的骨密度活体测定方法,如双能X射线吸收法、定量计算机断层扫描、定量超声等,骨密度与骨骼健康之间的关系,骨密度与胎次、妊娠哺乳、激素之间的关系等,旨在为动物肢蹄病治疗或淘汰建立一个预警标准,以最大限度地提升动物的生产性能和利用年限。

Abstract: Bone mineral density is an important index of bone strength,which is widely used in the evaluation of the bone health of human and animals.In recent years,the problem of animal limb and hoof has brought a certain degree of economic loss to the breeding industry,especially the pig industry.The determination of bone mineral density level will be helpful to establish the early warning standard of animal elimination in farm,timely treatment or elimination of animals with limb and hoof disease,reduce the breeding cost,and improve the production efficiency of farm.Since bone mineral density levels are predictive of hoof and limb problems,in vivo measurement of animal bone mineral density can greatly improve animal performance and longevity.The bone mineral density of mammals is affected by parity,pregnancy,lactation,and hormone.In vivo measurement of bone mineral density of mammals can timely reflect the bone health status of animals,so as to improve the bone mineral density of animals and the bone health status of animals.The author reviewed the research progress on bone mineral density at home and abroad in recent years,including several common methods of bone mineral density measurement in vivo,such as dual-energy X-ray absorption,quantitative computed tomography,quantitative ultrasound,etc.,the relationship between bone mineral density and bone health,and the relationship between bone mineral density and parity,pregnancy and lactation,hormone,etc.,so as to establish an early warning standard for the treatment or elimination of animal with hoof disease,and maximally improve the production performance and utilization life of animals.

Key words: bone mineral density; limb and hoof problems; tire; pregnancy; lactation; hormone
