Freshwatersoft-shell turtles experiment, this experiment same to previous experiment. 2plastic containers groups, snake 1.2-and3 40, 60 mg/kg intramuscularly. We note Table 1that when injected at a dose body weight, minimum onset timefor doses (15,7,5), while most time (17, 10, 5) respectively. While we noticed minimuma loss right reflex, deep anesthesia, recovery reflex completed (21,12,8),(47,58,76), (87,120,140) (18,24,64) that of40, (4,4,3), was(12, 5, recoveryright (8,4,5), (50,40,74),(290,260,290) (62,70,70) .Therefore, thebest is terrapin, soft shell tortoise it mg/kg. As ratsnake, weight best according study.
