Rf. Bo et al., IMMOBILIZATION OF COYPUS (MYOCASTOR COYPUS) WITH KETAMINE-HYDROCHLORIDE AND XYLAZINE HYDROCHLORIDE, Journal of wildlife diseases, 30(4), 1994, pp. 596-598
A combination of 100 mg/ml of ketamine hydrochloride (Ket) and 20 mg/m
l of xylazine hydrochloride (Xyl) was used to immobilize coypus (Myoca
stor coypus). Eight mature coypus (four males and four females) were i
njected intramuscularly with doses ranging from 2.33 to 6.25 mg/kg of
KET and 0.25 to 0.86 mg/kg of Xyl. The mean (+/-SE) time for induction
, arousal, and recovery were 7.3 +/- 2 min, 23.5 +/- 0.3 min and 46 +/
- 2.5 min, respectively. The mean +/- SE doses injected were 4.07 +/-
0.52 mg/kg Ket (range, 2.33 to 6.25 mg/kg) and 0.5 +/- 0.08 mg/kg Xyl
(range, 0.25 to 0.86 mg/kg). No adverse responses were observed in any
of the animals treated.
