Effects on fawn survival of multiple immobilizations of captive pregnant white-tailed deer.
Fawn viability was tested in captive, pregnant white-tailed deer (Odocoileus virginianus) immobilized with xylazine hydrochloride and ketamine hydrochloride and reversed by yohimbine hydrochloride or tolazoline hydrochloride. Nine pregnant does were immobilized 10 times each from December 1984 to May 1985. Their mean parturition date was 8 June. The number of fawns produced per pregnant doe was 1.88. Mean weight of newborn fawns was 4.18 kg. Seventy-five percent of the does produced twins or triplets. Three (20%) fawns died postnatally within 48 hr, but the remaining 12 survived for the full 72 hr they were allowed to remain with their dams. These observations compare favorably with those of non-immobilized captive deer on similar diets.
