Nutrient composition of plants consumed by black and white ruffed lemurs, Varecia variegata, in the Betampona Natural Reserve, Madagascar

Abstract 10.1002/zoo.20267.abs The purpose of this study was to quantify the concentrations of crude protein, fat, ash, neutral detergent fiber, acid detergent fiber, lignin, nonstructural carbohydrates, and gross energy in plant foods consumed by wild black and white ruffed lemurs (Varecia variegata). Calcium, phosphorous, magnesium, potassium, sodium, iron, zinc, copper, manganese, molybdenum, and selenium concentrations […]

Duikers: Native food composition, micronutrient assessment, and implications for improving captive diets

Abstract 10.1002/zoo.10037.abs This review summarizes and contrasts published information on the proximate chemical composition of native fruits and leaves eaten by duikers, and adds new data concerning the soluble carbohydrate, mineral, and tannin content of duiker foods. Information on circulating plasma concentrations of minerals and the fat-soluble vitamins A and E is also summarized in […]

Influence of diet transition on serum calcium and phosphorus and fatty acids in Zoo giraffe (Giraffa camelopardalis)

In response to new recommendations for feeding giraffe in zoos, giraffe (n = 6) were transitioned from a typical hoofstock diet to diets containing reduced starch, protein, Ca and P and added n3 fatty acids. This diet was fed as a 50:50 mix with alfalfa and grass hay. Over the next 4 years, serum Ca, […]
