Variation in voluntary intake of feeds by captive giraffe (Giraffa camelopardalis): Implications for meeting nutrient requirements

Data prompting evaluation of captive giraffe feed selection were obtained from a modified reversal study investigating the effects of dietary physical form and carbohydrate profile. Six non-lactating adult female giraffe (Giraffa camelopardalis reticulata) were used in seven 21-day periods. Supplements were: an experimental non-pelleted browser supplement (EF) and a mixture of 75% Mazuri Browser Breeder (PMI Nutrition International, LLC, Brentwood,...

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...
