Consistent differences in quantitative parameters of
gait structure were found across age groups between
ducks deemed to have the best (GS0) and the worst
(GS2) walking abilities. Despite this, within each age
category, except at 21 d of age, ducks completed 4 steps
in a similar amount of time, and the ducks deemed
to scored as GS2 traveled a shorter total distance as
compared to those scored GS0 (Table 2). In addition
to traveling a shorter distance, the time it took for
21 d old ducks to complete the 3 strides increased as
walking ability decreased. Body weight was included as
a covariable in the statistical model. Therefore, the difference
in body sizes was unlikely to be the main reason
for the difference in total distance traveled. The differences
more likely suggests that the GS2 ducks had
a labored walk. The greater difference in the average
amount of pressure exerted on the right versus left foot
