Transit time and digestibility of two experimental diets in the maned wolf ( Chrysocyon brachyurus) and domestic dog ( Canis lupus)
Abstract Recent research involving nutritional management of clinical disease secondary to cystinuria in captive maned wolves ( Chrysocyon brachyurus ) in the United States resulted in the production of a commercially manufactured maintenance diet and subsequently, a further modified experimental di...
