Diazepam-induced feeding in captive gray wolves (Canis lupus).
Diazepam doses of 0.2, 0.4, and 0.8 mg/kg induced feeding in sated gray wolves in a dose-dependent manner (p less than 0.001). Neither 0.8 mg/kg of the benzodiazepine antagonist, beta-CCP (p = 0.36), nor 0.8 mg/kg of the benzodiazepine inverse agonist, beta-CCE (p = 0.85), decreased the diazepam-induced hyperphagia. Five of 6 naive wolves (p = 0.003) ate dry dog food within 15.4 +/- 1.9 min of ...
متن کاملHelminth Fauna in Captive European Gray Wolves (Canis lupus lupus) in Germany
Captive as well as free-ranging wolves, which are currently recolonizing Germany, may harbor a variety of gastrointestinal parasites. This study investigated endoparasites in captive European gray wolves (Canis lupus lupus) using coproscopical methods. Fecal samples were collected monthly between October 2012 and November 2013 from 18 wolf enclosures in 14 German zoological gardens, representin...
متن کاملUse of tiletamine and zolazepam to immobilize captive Iberian wolves (Canis lupus).
A mixture of tiletamine and zolazepam (Zoletil) was used to immobilize 29 captive born Iberian wolves. Based on their excitability during handling procedures the animals were categorized as excited (n = 15) and unexcited (n = 14). We observed differences in the responses of these groups to the drugs. Although immobilized with higher doses (mean +/- SD of 6.94 +/- 2.13 versus 5.04 +/- 1.74 mg/kg...
متن کاملSerum biochemistry of captive and free-ranging gray wolves (Canis lupus).
Normal serum biochemistry values are frequently obtained from studies of captive sedentary (zoo) or free-ranging (wild) animals. It is frequently assumed that values obtained from these two populations are directly referable to each other. We tested this assumption using 20 captive gray wolves (Canis lupus) in Minnesota, USA, and 11 free-ranging gray wolves in Alaska, USA. Free-ranging wolves h...
متن کاملQuantity Discrimination in Wolves (Canis lupus)
Quantity discrimination has been studied extensively in different non-human animal species. In the current study, we tested 11 hand-raised wolves (Canis lupus) in a two-way choice task. We placed a number of food items (one to four) sequentially into two opaque cans and asked the wolves to choose the larger amount. Moreover, we conducted two additional control conditions to rule out non-numeric...
