Hematological and serum biochemical analytes reflect physiological challenges during gestation and lactation in killer whales (Orcinus orca)
Gestation and lactation result in metabolic alterations of the dam because of varying demands of the fetus and offspring during the different stages of development. Despite killer whales (Orcinus orca) having one of the longest gestations and highest birth weights of all mammals in human care, these metabolic alterations, and their impact on the physiology […]
Normal hematology and serum chemistry of northern fur seals (Callorhinus ursinus) in captivity
Northern fur seals (Callorhinus ursinus) are endemic to the North Pacific Ocean. They were hunted for their fur and became endangered in the late 1800s, but their populations recovered following the introduction of protection laws. Recently, populations have been decreasing again, although the reasons are unclear. For individuals that are bred and reared in captivity […]
