Leg lameness is a significant welfare concern in commercial broiler chickens, with up to 30% of birds severely affected. The National Chicken Council (NCC) animal welfare guidelines and audit checklist for broilers recommend gait scoring 100 birds/flock using a 3-point scale within one week of slaughter. This 0-2 scale was adapted for use with a unique walking lameness assessment platform to provide a more exact measurement on a consistent walking surface. Through trial and error, a successful method for simultaneously scoring two to three individual birds was tested. A similar structure is recommended for use on-farm to consistently and efficiently assign lameness scores in commercial broilers.
