Differences in gait parameter (Gait) between jungle fowl, (juvenile, ‘JF1’, and mature, ‘JF2’, n = 10), non-lame broilers, ‘GS0’ (n = 10), and lame broilers, ‘GS3’ (n = 12).

SD = stride duration, SL = stride length, ST = stance, DS = double-leg support, VL = vertical leg displacement, LB = lateral back displacement, VB = vertical back displacement, VEL = velocity. VELpoly = the order of polynomial degree attributed to relative velocity within the model. The coefficient (Coeff) gives the amount of change in measure (gait parameter) for a unit change in each variable (Group). A positive coefficient estimate indicates that an increase in the value of a variable is associated with an increase in the respective measure and a negative coefficient estimate indicates a decrease.aNormalised relative to hip height.
