Effects of Capturing Pregnant Moose and Calves on Calf Survivorship
Larsen DG and Gauthier DA. 1989. Effects of Capturing Pregnant Moose and Calves on Calf Survivorship. The Journal of Wildlife Management. 53(3):564-567
We assessed the effects of immobilizing pregnant moose (Alces alces) in late winter with combinations of carfentanil, fentanyl citrate, xylazine hydrochloride, and hyaluronidase (CFXH mixture) on pre- and postnatal calf mortality, and effects of capture and radiocollaring neonates on calf mortality. Prenatal calf mortality was not affected by immobilizing free ranging pregnant moose in late winter, and calf survivorship was not affected by the capture and collaring of neonates. Postnatal calf survivorship was reduced by immobilizing female moose 2 - 3 months prior to parturition.
