Marginal means and significance of main effects for the gait parameters in Experiment 1 for birds with low or high footpad scores and treated with a local injection of bupivacaine or saline

Main effect	Speed (m/s)	Peak vertical force (%BW1)	Impulse (%BW/s)	Single support time (s)	Double support time (s)	Stride length (cm)	Stride time (s)	Stance time (s)
Breed A	32.4	117.1	49.3	0.508	0.074	34.2	1.078	0.575

Low FPD	30.3	117.2	50.3	0.518	0.069	32.9	1.109	0.576
High FPD	32.7	111.0	47.4	0.482	0.100	34.1	1.062	0.581

SED	2.11	2.73	2.20	0.0251	0.0193	1.443	0.048	0.0268

The means are for the average of left and right feet except for speed and double support time. ¹BW, body weight; NS, not significant (P > 0.10).
