Abnormal Bone Metabolism May Be a Primary Causative Factor of Keel Bone Fractures in Laying Hens
Animals, 2021 Keel bone damage negatively affects the welfare, production performance, egg quality, and mobility of laying hens. This study aimed to investigate whether abnormal bone metabolism causes keel bone damage in laying hens.

Methods for assessment of keel bone damage in poultry [PDF]
Poultry Science, 2015 Keel bone damage (KBD) is a critical issue facing the laying hen industry today as a result of the likely pain leading to compromised welfare and the potential for reduced productivity. Recent reports suggest that damage, while highly variable and likely dependent on a host of factors, extends to all systems (including battery cages, furnished cages ...

, 2016 This thesis is an investigation of the effect of providing opportunities for exercise on long term bone health of laying hens, with an emphasis on keel bone damage. Osteoporosis in laying hens is a welfare concern as it increases the risk of bone fractures. The keel bone is especially susceptible to fracture during the laying period.

Development of an ex vivo protocol to model bone fracture in laying hens resulting from collisions. [PDF]
PLoS ONE, 2013 Fractures of the keel bone, a bone extending ventrally from the sternum, are a serious health and welfare problem in free range laying hens. Recent findings suggest that a major cause of keel damage within extensive systems is collisions with internal ...

Welfare Consequences of Omitting Beak Trimming in Barn Layers
Frontiers in Veterinary Science, 2017 Beak trimming is used worldwide as a method of reducing the damage to feathers and skin caused by injurious pecking in laying hens. However, beak trimming also causes some welfare issues as trimming the beak results in pain and sensory loss.
