Effect of dietary soluble fiber on gut microbiota in the sugar glider (Petaurus breviceps): a pilot study

The sugar glider (Petaurus breviceps) is an exudativore in nature, eating plant gums, saps, resins, manna, and nectars as well as insect-based honeydew and lerp, with proportions of various ingredients highly dependent on seasonality and locale (Smith, 1982; Howard, 1989). Despite a well-developed cecum that could, in theory, harbor microbial populations with fermentative capabilities (Hume, 1999), a majority of captive...

Advances in feline nutrition 2: evaluations of protein and fiber sources for raw meat based diets in captive exotic felids

Little nutritional or metabolic information has been collected from captive exotic felids fed raw diets. In depth data on nutrient composition (e.g., fatty acid and amino acid composition) are sparse, and may impact diet formulation. Additionally, although several studies have examined total tract nutrient digestibility in captive exotic felid, (Clauss, et al., 2010; Vester, et al., 2010a) most have focused on horsemeat and beef-based...

An update on giraffe (Giraffa camelopardalis) response to dietary fiber form and carbohydrate profile: implications for animal health

An experimental coarse browser supplement (EF) and a mixture of 75% Mazuri Browser Breeder and 25% Omelene 200 (GF) were used to evaluate the effects of dietary physical form and carbohydrate profile on six non-lactating adult female giraffe (Giraffa camelopardalis reticulata) in a modified reversal study using seven 21 day periods. Individually housed giraffe were fed ad libitum alfalfa hay,...

OBSERVATIONS ON WEIGHT LOSS AND FECAL CONSISTENCY IN GIANT ANTEATERS (MYRMECOPHAGA TRIDACTYLA) DURING THREE TRANSITIONS FROM A MIXED NATURAL IN-HOUSE TO COMMERCIAL COMPLETE DIETS

Giant anteaters (Myrmecophaga tridactyla) are highly specialized insectivores with low energy requirements compared with similar-sized mammals and an exceptional feeding apparatus and behavior.6,7 Common health problems which have been attributed to suboptimal nutrition are loose stool or diarrhea, anorexia, tongue tip constriction or vitamin K deficiency.4,8 Traditional, natural in-house diets typically include dog kibble, cereals, honey, milk products, meat and...

Herbivore carbohydrate nutrient analysis: the next generation

The proximate analysis system attempted to separate dietary carbohydrates into fiber and non-fiber portions. Under this system, any matter unaccounted for after subtraction of ash, crude protein, ether extract, and crude fiber from total dry matter was assumed to be non-fiber carbohydrates. Due to loss of variable amounts of fiber (cellulose and hemicellulose) and lignin during analysis, the proximate analysis...

Fiber digestibility in black lemurs (Eulemur Macaco Macaco)

Black lemurs are classified as generalist feeders, existing on both fruits and leaves depending upon seasonal availability. In captivity they are typically fed a diet of commercially manufactured primate biscuits and readily available produce, both of which are limited in fermentable fiber. Digestibility trials were conducted on fourteen black lemurs, housed in 4 groups (4, 3, 3 & 2) and...

Intake and digestion in babirusa (Babyousa babyrussa) and red river hogs (Potamochoerus poreus) fed high fiber diets

Previous studies suggest that fiber-digestion capacity of exotic swine species has not been challenged in captive feeding programs. Zoo diets are often low in dietary fiber, which may contribute to obesity, with accompanying joint and possible reproductive problems. Five-day feeding trials were conducted with 3 adult (2.1) babirusa (BAB) (Babyrousa babyrussa) housed separately, and 2 (1.1) adult red river hogs...
