EASTERN CONSERVATION AREA VETERINARY UNIT MONTHLY REPORT

Report by: Bernard Rono, Veterinary Officer

Summary

This report describes the activities of the Meru veterinary unit in northern Kenya in April 2016. Many parts of northern Kenya received rainfall in April, therefore adequate browse and water was available for wildlife.

In Ol Jogi wildlife conservancy a female giraffe with an obstructed birth was treated. In El Karama ranch an elephant showing severe lameness was attended to while in Meru national park we treated a white rhino for cutaneous filariasis.

This unit is supported by the David Sheldrick Wildlife Trust.

CASE #1: DYSTOCIA IN A RETICULATED GIRAFFE

Date: 10th April 2016

Species: Reticulated giraffe

Sex: Female

Age:  Adult

Location: Ol Jogi ranch

History

A female giraffe in Ol Jogi Wildlife Conservancy was seen with a dead fetus in its birth canal for two days. Veterinary intervention was required to save the giraffe from severe endotoxemia as it was unable to push the fetus out. 

This giraffe was raised at an orphanage in the conservancy and later released into the wild. It was a first time mother.

Immobilization, examination and treatment

Immobilization was achieved using a combination of Etorphine hydrochloride 10mg and Azaperone tartate 40mg in a 1.5cc Dan-Inject dart from foot. Five minutes later the giraffe was roped to lateral recumbency.

The giraffe is immobilised as a foetus is stuck in her birth canal  The legs of the foetus are clearly protruding

Genital examination showed a dead fetus on anterior longitudinal presentation and dorsal - sacral position.  The extended head, neck and front limbs were protruding from the vulva. Fetal – maternal disproportion (small birth canal) was suspected as the cause of dystocia.

The foetus has to be extracted and is confirmed to have already died  The birth canal is lubricated and ropes tied around the feet

Liquid paraffin was applied liberally to lubricate the birth canal. Ropes were applied in loops on the distal metacarpus to aid in traction. The fetus was manipulated gently and manual traction applied caudally and ventrally. A fully formed dead male fetus was delivered.

The vet gently manipulates the foetus  The male calf is finally extracted still born

Fetal membranes were trimmed from the uterus and Oxytetracycline pessaries administered. Parenteral antibiotic and analgesic drugs were also injected.

Prognosis

This giraffe was reported to have recovered one week after treatment. It is expected that this giraffe will be able to breed in future.

The female giraffe should make a full recovry  There is a good chance she will be able to breed in the future

CASE #2: CUTANEOUS FILARIASIS IN A WHITE RHINO

Date: 12th April 2016

Species: White rhino

Sex: Male

Age:  Adult

Location: Meru national park

History

A male rhino in Meru National Park was reported to have shown a large cutaneous wound on the abdomen which required treatment. The wound had grown progressively over a period of two weeks.

Immobilization and examination

The rhino was immobilization with a combination of 5mg Etorphine and 60mg Azaperone in 1.5cc Dan-Inject dart from a helicopter. The rhino was darted in the left rump and induction time was 7 minutes.

The rhino is darted for treatment of a large cutaneous wound  Filarial wound on a rhino

Examination showed ulcerative cutaneous wounds with serrated edges and pockets of pus. Wounds emitted a foul smell due to tissue necrosis caused by bacterial infection. These wounds are characteristic of cutaneous filariasis. The wounds were thoroughly washed with water diluted with hydrogen peroxide and then the necrotic tissue was cut away. Tincture of Iodine soaked in gauze swabs was applied and 1% Ivermectin 300mg and 20% Oxytetracycline administered subcutaneously and intramuscularly.

The wound is cleaned and treated  Iodine is applied

Reversal

Anesthesia effects were reversed within 3 minutes of intravenous injection of Naltrexone Hcl 150mg.

Prognosis

Filarial wounds respond to Ivermectin and antibiotic treatment, therefore this rhino is expected to make a speedy recovery. The rhino monitoring team will observe and report on their progress.

Antiseptic spray is also applied  Filarial wounds respond well to treatment

CASE #3: POST MORTEM EXAMINATION OF A RHINO

Date: 16th April 2016

Species: Black rhino

Sex: Female

Age: Adult

Location: Ol Pejeta Conservancy

A female black rhino carcass was found in Ol Pejeta Conservancy on 16th April 2016. Both horns had been removed by suspected poachers. A post mortem examination of the carcass showed that it had several gunshot wounds to its chest. Severe internal hemorrhage was also observed in the thoracic and abdominal cavities. Projectiles consistent with small caliber fire arms were removed from the colon, pectoral muscles and the muscles of the forelimb. A female fetus in first trimester gestation was found in the uterus. Our findings showed that this black rhino died from severe hemorrhage due to gunshot injuries.

The horns were removed by poachers  A recovered bullet

CASE #4: LAMENESS IN ELEPHANT

Date: 25th April 2016

Species: Elephant

Sex: Male

Age:  Adult

Location: El Karama ranch

History

This elephant showed severe lameness and a swollen left thigh. It was first seen on 24th April and treatment was carried out one day later.

Immobilization was achieved using 18mg Etorphine in a 3cc Dan-Inject dart from foot. Induction time was eight minutes after which the elephant fell onto sternal recumbency. The elephant was roped to right lateral recumbency for examination.

An elephant with a severe limp was seen  The elephant was immobilised for treatment

Examination and management

The left thigh was grossly enlarged and warm to touch. Crepitus was felt on manipulation of the limb. A tentative diagnosis of fracture of the femur was made. An attempt to radiograph this leg was not successful due to huge muscle mass. Conservative treatment was attempted using parenteral antibiotics and anti – inflammatory drugs.

The leg was severely swollen  An X-Ray was unsuccessful but a fracture was confirmed

Reversal

To reverse the effect of anesthetic drugs Diprenophine Hydrochloride was injected intravenously. After three minutes the elephant was assisted to standing position. However excessive mobility and leg deformity was later noted when this elephant walked off which confirmed a fracture and euthanasia was arrived.

Post mortem findings

There was a hematoma affecting the muscles of the femur and comminuted fracture of the femur with severe bone displacement.
