Metabolic bone disease in a white‐faced saki (Pithecia pithecia)

Abstract

AbstractNon‐human New World primates are recognized as particularly susceptible to metabolic bone disease. Improper UV light exposure and/or insufficient dietary levels of vitamin D can lead to poor bone development and skeletal mineralization deficits. This report documents the clinical progression of rickets, a type of metabolic bone disease, in a white‐faced saki (Pithecia pithecia), presenting the first documented case, to our knowledge, of this condition in this primate species. Because inconsistent feeding habits and seasonality are believed to have contributed to the development of rickets in this individual, adequate UV light exposure and adequate levels of dietary vitamin D are important considerations for individuals housed indoors and during periods of growth, ensuring adequate calcium regulation and prevention of sequela associated with low calcium and vitamin D levels. Through a multi‐faceted approach targeting medical, dietary, and husbandry changes, primate species exhibiting signs of metabolic bone diseases can be successfully managed to allow for a good quality of life.
