Oklahoma Zebra with Foot Infection Loses the Battle

For quite a while now, I've been following the travails of a Grevy's zebra at the Oklahoma City Zoo. Zephra has reportedly been treated for laminitis for the past three months or so. Carrie Coppernoll, a journalist with the local newspaper, the Oklahoman, was willing to share her report and the paper also has a video, which details treatment of an abscess or infection.

Carrie's reports have been beautifully illustrated with photos by the Oklahoman's photographer, Paul Hellstern. 

Today Carrie Coppernoll shared the outcome of the case.

Sadly, Zephra didn't survive her foot problem. Carrie has kindly shared some of her report, which appeared in The Oklahoman today. Carrie attributes her information to Jennifer D'Agostinodirector of veterinarian services at the Oklahoma City Zoo.

In August, Zephra was diagnosed in August with laminitis of unknown origin. According to D'Agostino, the zebra's pain was temporarily relieved when the zoo's farrier applied a shoe to the hoof.

Carrier writes: "But Zephra began to limp again, and a more extensive exam revealed a painful abscess. She was immobilized several times so experts from throughout the state could help treat her. Because Grevy's zebras are wild and aggressive, Zephra had to be anesthetized for each treatment.

'Despite treatment, her pain and the infection wouldn't go away,' D'Agostino said. 'The tip of the bone inside her hoof was dying. The only solution was surgery'."

Henry Jann, an equine surgeon from Oklahoma State University Center for Veterinary Health Sciences, performed the surgery November 10. 

According to Coppernoll's report, the surgeon created an opening into the sole of the zebra's hoof, removed the dead bone, packed it with antibiotics and wrapped it in a hard cast.

Coppernoll continues: "Zephra showed a lot of promise for the next week, D'Agostino said. 'She was doing great, She was walking without hardly any limp.'

However, Coppernoll reported, Zephra quickly deteriorated. She wrote "The infection got worse and her foot began separating from the hoof. Zoo officials cleaned her and gave her another day. 

"But when they unwrapped the bandages on November 23, they knew the problem was too much for her to overcome."

D'Agostino said. 'As soon as we took the bandage off,' she said, 'we knew'.”

Zephra was euthanized.

Coppernoll continues: "Zephra's body has been donated to Skulls Unlimited. Her bones will either end up on display at the Museum of Osteology or become part of an educational exhibit, D'Agostino said.

She quoted the veterinarian: “The whole time we thought it was all going to be fine. The infection got the better of her,” she said. “We knew that this was the road it could go down.”

Many zoo animals receive infrequent hoofcare services because of restraint issues and the danger involved. Some zoos have elaborate training projects to improve the quality and frequency of their hoof trimming for the animals.

Another encouraging post script to the Oklahoma story is that many of the glue-on and strap-on products used on horses have been adapted for zoo animals so that their hooves can be supported or stabilized with minimal trauma. In the past, it was difficult to figure out how to apply a brace, for example, that could be used on zoo animals.

Shoot big game...with hoof adhesives.
Vettec adhesive and supportive urethane-based products have been used quite a bit in zoos, as have PMMA adhesive products, I know, and I would imagine that casting tape would come in handy.

Will hoof boots in sizes and shapes to fit exotic animals be the next thing on our new products page?

In the months to come, Hoofcare + Lameness will be exploring some of the advances in zoo husbandry and medicine. I look forward to seeing the first business card reading "Equine and Exotic Podiatry Services"!

So what exactly is an "equine podiatrist"? There is a farrier and a veterinarian and a surgeon, but what is the role and qualifications of a podiatrist?
