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
