Keel bones fractures – a model for demonstration of causes and the significance of onset of lay

The project aims at establishing an experimental model for keel bone fractures in egg laying hens. The experimentally induced fractures will be described in detail and the results will be compared to the spontaneously occurring fractures. The results will provide new insights to the pathogenesis of the fractures.

Additionally an observational study will investigate the importance of the onset of lay. Flocks with different age at the onset of lay will be followed through the production period in order to map out differences in the prevalence of the fractures.    

The project will be carried out during 2019 and is funded by "Fjerkræafgiftsfonden".
