Macronutrient selection in mammalian insectivores at Busch Gardens Tampa Bay

This study determined macronutrient target of several mammalian insectivore species including 3-banded armadillo, aardvark, tamandua (lesser anteater), and greater anteater. These insectivores are often maintained on a commercial insectivore diet, which may or may not be appropriate for every species in this diverse and polyphyletic group. Animals were fed three experimental diets that varied in their proportions of calories from...

Nutrient composition of the milk of the giant anteater (Myrmecophaga tridactyla)

Little information exists about milk composition in obligate insectivores or in members of the mammalian superorder Xenarthra. A total of 37 milk samples collected from 3 lactating giant anteaters (Myrmecophaga tridactyla) were assayed for proximate nutrient content at the Nutrition Laboratory of the Smithsonian Conservation Biology Institute using standard methods developed at the Nutrition Laboratory. Water comprised 88.7 ± 2.1%...

Dietary taurine supplementation and cardiac function in the giant anteater (Myrmecophaga tridactyla): preliminary findings

Taurine is not considered an essential amino acid in most mammals as it can be synthesized from cysteine. Cats are an exception, lacking an enzyme necessary for this conversion and a lack of dietary taurine has been linked to central retinal degeneration and dilated cardiomyopathy. This form of feline cardiomyopathy is reversible with a dietary taurine supplement. More recently, a...

Normal serum vitamin E values in giant anteaters (Myrmecophaga tridactyla)

Baseline serum alpha-tocopherol (alpha-toc) values in captive giant anteaters have not previously been defined. Cats and dogs are typical models for carnivore nutritional physiology and may prove useful for evaluating vitamin E (vit E) nutrition in zoo carnivores. The objective of this study was to determine serum alpha-toc as a measure of vit E status in captive anteaters, for comparison...

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...
