Effects of etorphine (0.1 mg.kg −1 ) injected intramuscularly (time = 0) on ventilation (A), cardiac output (B) and global ventilation perfusion ratio (C) in goats (mean ± SD, n = 12). # P < 0.05 pre-etorphine vs. post-etorphine (repeated measures one-way ANOVA with post hoc Dunnett’s test) at time 2, 6, 10 and 14 min.
