“…Although often causing serious and gross clinical conditions, metabolic bone diseases are commonly treatable and reversible. They are rare in wild populations, and commonly associated with a species expanding its home range into an area of 'suboptimal habitat', characterised with a reduced availability of calcium-rich food (Fidgett and Dierenfeld 2007). The results of our macroscopic assessment of the RCS collection support this.…”

Lessons from the Past: Metabolic Bone Disease in Historical Captive Primates

2015

Primate welfare in captivity has significantly improved over the last century, due to the advances made in providing an adequate diet and environment. The skeletal collections of museums provide evidence of this shift in captive care, because metabolic disease caused by dietary deficiency or inappropriate surroundings can cause deformation to the hard tissues. The Royal College of Surgeons of England (RCS) holds a collection of 1,507 non-human primate skulls in its Odontological Collection, the majority donated prior to the mid twentieth century from various sources. We observed a recurring gross pathology in 51 of these skulls, noted in museum records as captive animals. In all cases, general bone thickening with decreased bone density is the main feature and primarily involves the bones of the maxillofacial region and mandible. We computer tomography scanned a sub-sample of these skulls to further investigate these pathological features. We compared the RCS historical collections and a more recent captive primate collection at the National Museum of Scotland. The findings suggest that a metabolic bone disease is the causative agent, with osteomalacia the likely diagnosis. Osteomalacia typically occurs due to malnutrition and/or insufficient ultraviolet light exposure and in this case reflects the inadequacy of zoo primate management during the late nineteenth and early twentieth centuries. Developments have since been made in captive animal welfare, due to improvements in nutrition and environment. Metabolic bone disease in primate captivity can be regarded as a lesson from the past.

“…Caudal to the choanae, an infundibular fissure is present, located medially and represents the opening of the auditory tube (Denbow, 2000;Singh, 2018). The features observed by us regarding the oral cavity were also reported by Fidgett & Dierenfeld (2008). For the other listed species, these features were not found in the literature.…”

Birds are the most diversified organisms on Earth, with species covering various niches in each major biome, being essential to understand the modern ecosystem. This study concentrates on the diversification of the anatomical structure of the upper digestive tract for 26 species of zoophage-polyphagous birds and the anatomical differences in the digestive system to reveal aspects related to their evolution and diversification. The trophic spectrum of the selected birds includes several categories of food, or, as in the case of strictly carnivorous birds, to a single food category. After performing the dissections, the digestive tract was separated from the carcass and each digestive segment was measured and analysed. In this study, it was demonstrated that the birds' feeding behaviour influence the macroscopic particularities of the digestive system, more visible in the cranial portion (oropharyngeal cavity, esophagus, proventriculus and gizzard), with little descriptive information in the literature. The tongue is poorly developed and immobile in piscivorous birds, while the tongue of insectivorous birds is long and moves considerably away from the tip of the bill. The esophagus was stretchable and presents longitudinal folds on its entire surface in piscivorous species and not extensible in insectivorous birds.

“…Link nutrition to poor health (e.g. Fidgett & Robert, ; Cork, ; Crissey et al ., ; Péron & Grosset, ), associated veterinary costs, poor egg production and low chick viability (Houston & Fidgett, ; Fidgett & Dierenfeld, ), and suddenly the subject becomes more important.…”

At a time when zoo populations are being relied upon for future progeny and long‐term sustainability of our avian populations, nutrition is vitally important. However, diet review, evaluation and change are often met with disinterest and complacency. Link nutrition to poor health, associated veterinary costs, poor egg production and low chick viability and suddenly the subject becomes more important. High standards are expected in other aspects of avian husbandry yet the nutritional composition of the diets often remains unknown. This article highlights advances in nutrition, useful resources, means of keeping feeding records, and tools available to evaluate and review avian diets in nutritional terms. Regularly reviewing diets ensures the nutritional care of birds keeps pace with other areas of husbandry.
