The effects of ? 2 - agonists detomidine at the dose rate (0.4 1ug / kg / min over 10 min), medetomidine (0.2/Ag / kg / min over 10 min) and romifidine (0.4 µg / kg / min over 10 mm) were studied in goats. The drugs induced decreases in body temperature and bradycardia. The drop in body temperature induced by ?2 - agonists was preventend by atipamezole pre - treatment, whereas the induced bradycardia was not modified by this ? 2 - antagonist.
