Variation in digestive efficiency of captive North American river otters (Lontra canadensis) on various diets

Abstract 10.1002/zoo.20116.abs Energy content, proximate nutrient values, passage rate, and digestive efficiency associated with various diet types and factors affecting these parameters have not been quantified for the North American river otter (Lontra canadensis). We measured energy digestive efficiency (DEff) and intestinal passage rate of three captive river otters on their regular diet (a combination […]
