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...

The effects of fiber type and fiber levels on digestibility and volatile fatty acid formation in the Orangutan (Pongo pygmaeus)

The diets of free-ranging orangutans are high in structural cell wall material, which comprises the fiber fraction in plants [Hamilton and Galdikas, 1994]. Microbial populations residing in the hindgut accomplish fiber digestion via fermentation. Animals use volatile fatty acids, end products of fiber fermentation, as a source of energy. Readily available produce items contain small amounts of fermentable fiber [Schmidt...

The influence of plant chemistry on browse choice in Angolan Colobus Monkeys (Colobus angolensis palliates)

Browse is included in the diets of many primate species, especially those that consume large portions of leaf material under free-ranging conditions. The challenge of providing a reliable source of browse is complicated by the limited availability of plant species that are nutritionally adequate, palatable, and available in suitable quantities to meet the demands of the animal collection.

Influence of fiber source on apparent digestibility, rate passage and fecal consistency in small felids fed a beef-based carnivore diet

In a crossover design, four adult animals, a male and female Amur leopard cat (Prionailurus bengalensis euptilura) and a male and female Turkmenistan caracal (Caracal caracal michaelis) were fed three fresh-frozen beef based diets containing different sources of fiber; beet pulp (BP), fructooligosaccharides/cellulose blend (FOS), and wood cellulose (Solka Floe®) (WC). Assessment included food intake, fecal consistency, animal body weight,...

Effect of dietary fiber concentration on apparent digestibility and digesta passage in non-human primates. II. Hindgut-and Foregut fermenting folivores.

Two test diets with different acid detergent fiber (ADF) concentrations (15% ADF, 30% ADF) were fed to seven adult hindgut- and seven adult foregut-fermenting primates. Apparent digestibilities (%) of dietary dry matter (DM), gross energy (GE), and fiber components (neutral detergent fiber [NDF], ADF, hemicellulose [HC], and cellulose [C]) were measured. Rates of digesta transit (TT1) and retention (RGIT) times...

Effect of dietary fiber concentration on apparent digestibility and digesta passage in non-human primates. I. Ruffed lemurs (Varecia variegate variegate and V. v. ruba)

Two test diets with different fiber concentrations (15% acid detergent fiber [ADF], 30% ADF) were fed to five adult female ruffed lemurs (Varecia variegata). Apparent digestibility (%) of dry matter (DM), gross energy (GE), and fiber components (neutral detergent fiber [NDF], ADF, hemicellulose [HC], and cellulose [C]) were measured. Rates of digesta transit (TT1) and retention time (RGIT) were assessed...

The use of fecal inoculum to determine the rate and extent of in vitro fermentation for cellulose, beet pulp, citrus pulp, and citrus pectin across three lemur species: Varecia variegate, Eulemur fulvus, and Hapalemur griseus

In order to estimate fermentative capacity among lemur species, four fiber substrates were tested across three herbivorous species: Eulemur fulvus, Hapalemur griseus, and Varecia variegata. Substrates were cellulose (CE), beet pulp (BP), citrus pulp (CP), and citrus pectin (PE), which ranged in composition from completely insoluble fiber (CE) to completely soluble fiber (PE), respectively. Animals were offered the same diet...

The potential to increase neutral detergent fiber levels in ape diets using readily available produce

Many studies report what wild orangutans (Pongo pygmaeus) select for food. Hamilton and Galdikas (1994) determined wild diets contained dietary neutral detergent fiber (NDF) levels of 75%. NDF represents structural polysaccharides (cellulose and hemicellulose (HMC)) potentially digested by microbial fermentation in the lower gut. Fiber presence in the gut and fermentation end-product production have been shown to prevent obesity and...

The effect of bamboo intake on fecal consistency in Giant Pandas (Ailuropoda Melanoleuca)

Although taxonomically classified as a carnivore, the giant panda (Ailuropoda melanoleuca) has evolved to consume a herbivorous diet consisting primarily of bamboo. Traditional captive feeding strategies have not reflected the natural diet and instead combined readily digested animal products and high-starch grain mixtures fed with variable amounts of bamboo. Improper nutritional management may lead to gastrointestinal disorders, often manifested as...

Evaluation of eight species of native Texas browse as suitable forage substitutes for black rhinoceros (Dieros bicornis)

Duplication of natural foodstuffs for animals in captivity can be a difficult task. While it may not be possible to provide food sources normally available in an animal’ s natural habitat, a prospective goal might be to provide similar nutrients from locally available foods. Eight species of native Texas browse were studied for adequacy as a source of browse for...

The influence of dietary fiber on digestibility, passage rate, and body mass in captive baboons (Papio Anubis)

This was a preliminary study in which nutrient digestibility, digesta passage rate and body mass were determined for a captive group of baboons (Papio anubis). The group consisted of 6 adult, nonpregnant females. Three experimental diets, varying in acid detergent fiber (ADF) content, were fed. The fiber content of the experiment diets was: diet1=10.45% ADF, diet2=18.30% ADF and diet3=30.40% ADF.
