¹ P-values for the statistical model were effect of floor space treatments (P = 0.77), effect of sampling time (P = 0.07), effect of station (P = 0.002), and interaction of station and floor space treatments (P = 0.22).

²Linear or quadratic effects of floor space treatments within sampling time.

³Sample collected when pigs weighed about 80 kg.
