Effect of Period, treatment and interaction of Period and treatment are indicated with p values
Means within a column having different superscripts differ significantly (p < 0.05)
The standard error uses pooled estimate of error variance
RT Rectal Temperature (°C), RR Respiratory rate (breathes/minute), PR Pulse Rate (beats/minute)
