ABSTRACT
Impaired walking ability is an economically important welfare problem that affects poultry raised for meat production, including Pekin ducks. To gain a better understanding of the impacts of walking impairments on duck production, and to identify contributing variables and plausible remedies, an accurate measure of walking ability must first be defined. The
viability of a 3-point gait score system for characterizing the walking abilities of Pekin ducks was evaluated. Specifically, we examined whether the qualitative gait score categories corresponded to quantitative gait parameter measures, and evaluated the inter- and intrarater reliabilities of the gait score system. Commercial Pekin ducks aged 13 to 14 d (14 d; 248 ducks), 20 to 21 d
(21 d; 350 ducks), and 30 to 32 d (31 d; 368 ducks), were
video recorded and gait scored using a 3-point system
(GS0 = best gait; GS2 = poor gait) as they crossed a
Tekscan R gait analysis system. Gait structure parameters
were calculated based on 4 steps made by each
