Flooring Challenge Systems Expose Susceptibility to Lameness

Description:

BACKGROUND

High incidences of lameness occasionally develop in flocks of rapidly growing commercial chickens. Lameness includes all birds that become unwilling or unable to walk due to a variety of innate or induced pathologies affecting their musculoskeletal systems. In the past, lameness has been difficult to trigger at significant levels in research flocks, hindering the development and testing of prophylactic or therapeutic treatments.

 

TECHNOLOGY

We found that flooring materials that induce unstable or insecure footing cause added torque, stress and strain on key leg joints, thereby exacerbating and accelerating the development of BCO (Bacterial Chondronecrosis with Osteomyelitis) lesions and clinical lameness. We designed and tested a variety of flooring challenge systems arranged in different configurations that were likely to cause footing instability and thereby challenge the key joints of the legs. Our "flooring challenge system" induces significant levels of lameness in experimental flocks of broilers.

 

ADVANTAGES

Our flooring challenge systems induce broilers to express significantly higher levels of lameness when compared with broilers reared on traditional floor litter. Our systems are portable and can be adapted to a wide range of floor pen sizes, so selection for resistance to lameness can be conducted on a commercially practical scale.

 

This technology has been validated by major poultry companies and can be used to screen both genetics and products for poultry health.
