Arterial oxygenation and acid-base status before and during oxygen supplementation in captive European bison () immobilized with etorphine-acepromazine-xylazine.

Chemical immobilization of captive European bison () is often required for veterinary care, transportation, or husbandry practices playing an important role in conservation breeding and reintroduction of the species. We evaluated the efficiency and physiological effects of an etorphine-acepromazine-xylazine combination with supplemental oxygen in 39 captive European bison. Animals were darted with a combination of 1.

Gastrointestinal parasites of captive European bison Bison bonasus (L.) with a sign of reduced efficacy of Haemonchus contortus to fenbendazole.

The history of European bison Bison bonasus Linnaeus, 1758 has been stormy since its extinction in the wild after the First World War. Due to the fact that the species was restored from just 12 founders, further expansion has suffered from low genetic variability, rendering the bison vulnerable to various pathogens due to inbreeding depression. Parasites are recognised as a key biological threat to bison population.
