Since our founding in 1948, Morris Animal Foundation has funded more than $51 million in research to protect, treat, and cure the world’s companion animals and wildlife.
Along the way, our studies have led to major advances in veterinary care, including vaccines and other preventions, diagnostic tools and new therapies for the diseases and health conditions that threaten the lives of the animals we love. You can search our completed-study database by species and/or disease to learn more about our successes.

D05ZO-616: “Comparative Study of Tannin Concentration of Browse, Fecal Parasites and Fecal Steroid Content of Captive and Wild Black Rhinoceros”
principal investigator: Lucy James, student, Royal Veterinary College
completed
Project Mentor: Mark T. Fox, BVetMed, PhD, ILTM, MRCVS
The Black rhinoceros is critically endangered and has been found to not breed well in captivity. This project aimed to investigate areas of this animal’s diet, internal parasites, and stresses in different environments. The investigator studied one zoo population and four wild populations (Kenya). She found that cortisol levels, an indicator of stress, were significantly higher in captive populations, particularly females, which may be adversely affecting reproduction. Regarding parasites in the samples, the investigator did not find a significant difference in the parasites identified at the different non-captive locations suggesting translocated animal placement should not be affected. Finally, this scientist was looking at tannin (a compound that occurs in plants) concentration in the diet. She found that the this animal does not seek forage with high levels of condensed tannin (CT).
Lucy says, “This project has enhanced my desire to become further involved in conservation related research in the future…”
