Diets offered to maned wolves (Chrysocyon brachyurus) in North American zoos: a review and analysis

The maned wolf, a canid native to South America, has had a history of cystinuria and poor fecal consistency in North American institutions. Factors contributing to this may be related to feeding the species a primarily carnivorous diet, despite its omnivorous dietary habits under free-ranging conditions. To address cystinuria and fecal consistency, a commercially manufactured diet was fed to all...

The captive Maned Wolf (Chrysocyon brachyurus): Nutritional considerations with emphasis on management of cystinuria

An important and widely recognized condition of the maned wolf is cystinuria, or excess levels of cystine in the urine. Cystinuria has been identified in the majority of maned wolves tested, both in captivity and in the wild. Cystinuria also occurs in humans and domestic dogs, and has been demonstrated in these species to have a genetic basis. In all...

Maned wolf nutritional management

The difference between facultative and strict carnivores may be illustrated by comparing the domestic dog and the domestic cat. Many canids have broad feeding habits, including a variety of fruits and other plant parts in their natural diets. By contrast, felids show no tendency to omnivory; they are all essentially predators. Nutritional studies indicate that the domestic dog and the...
