Polar Bear (Ursus maritimus) Adipose Tissue Fatty Acid Composition Compared to Fatty Acid Constituents of a Common Milk Replacer
Abstract 10.1002/zoo.20108.abs This study compared the fatty acid composition of polar bear (Ursus maritimus) adipose tissue (n=2) to the fatty acid (FA) composition in published literature for maternal milk (n=3 samples) and a primary milk formula (liquid Esbilac, Pet Ag Inc., Hampshire, IL) commonly used in hand rearing, to look at possible dietary influences on […]
The gross anatomy, cellular structure, and fatty acid composition of adipose tissue in captive polar bears (Ursus maritimus)
Abstract 10.1002/zoo.1430120304.abs The gross anatomy, microscopic structure, and fatty acid composition of adipose tissue in four elderly polar bears (Ursus maritimus), that had each been in captivity for more than 24 years, were compared with that of young wild specimens. Total dissections were performed on two specimens. In both, the proportion of adipose tissue in […]
Evaluation of an alternative to feeding whole frozen fish in belugas (Delphinapterus leucas)
Abstract Feeding fish to captive piscivores can be challenging owing to cost, availability, variability in nutrient, and caloric composition, as well as handling and storage concerns. This trial evaluated the response of three belugas to being fed Fish Analog, an alternative to frozen fish. Body condition, gut transit time, serum chemistry and metabolic hormone analytes, […]
