CMU February 2025 Updates

For a short month, the Chiang Mai University Mobile Vet Clinic was busy with several cases. Interestingly, 45% of the cases last month were due to eye concerns. There were also a handful of wounds which needed tending, a couple of foot injuries and a nursing issue.

Upon arrival at their first case, the team found the elephant standing calmly in front of tourists, eating, and appearing generally fine. However, her left eye exhibited excessive tearing and squinting. A visible wooden stick was embedded at the outer corner of the eye, and the third eyelid was swollen and protruding, obscuring the eyeball. To the vet’s surprise, the stick was larger and longer than expected. Fortunately, there was no bleeding after extraction. The eye was rinsed with a saline solution and treated with antibiotic eye drops. Once the pain subsided, a hole-like wound was observed. Given the risk of deeper injury, the cow was transferred to hospital for further diagnostic imaging and intensive care. Thankfully, the eye globe structure remained unharmed, and her vision was preserved.

At the second case, the mahout reported an adult female elephant experiencing excessive tearing for a couple of days and noted that she had been playing in the dirt frequently. In response, they began cleaning her eye with clean water more frequently. Upon examination, the veterinarian observed a whitish spot on the cornea, diagnosing a superficial corneal ulcer. After demonstrating the proper application of topical eye drops to the mahout, recommending administration four times daily, and an anti-inflammatory drug was provided for three consecutive days the team also advised keeping the elephant in the shade to enhance her comfort and support healing. At the follow-up visit two weeks later, her eye had cleared completely.

The other two cases of lacrimation (excessive tearing) were similar cases in two very different patients. One case was that of an adult female and the other a two-month-old calf. In both cases, fluorescein staining was performed, and both results were negative, confirming no corneal damage and mahouts at both locations were instructed in methods to help rinse and clean the eyes of their elephants, especially after playing in the mud and dirt.

In addition to the other cases the CMU Mobile Vet Clinic was requested to conduct a health examination, with a focus on foot care, for an adult male tusker elephant who had sustained injuries from a mine explosion 10 years ago. He had chronic wounds on both hind limbs and was recently rescued and transported from a border area to a camp in Mae Rim. In terms of gait analysis, he was able to bear weight on all four limbs. The mahout led him into the river for a bath before the examination. During the assessment, they found a severely open wound on the left hind footpad. The right hind foot had an open wound on the footpad and an abscess at the nail base, which extended deep into the foot. Both wounds emitted a strong odor. Due to the lack of appropriate facilities for foot trimming and intensive foot care, and since the elephant was still in the process of training and familiarizing himself with the mahout, the team focused on wound management and trained the mahout team on proper wound care techniques suitable for the current situation. The wound care process involved cleaning the affected areas with a chlorhexidine solution, brushing out debris and dirt, and repeatedly rinsing with saline and povidone-iodine solution. After drying the wounds with gauze, an antibiotic ointment was then applied.

CMU Mobile Vet Clinic January Updates

Each year, organizations responsible for elephant health conduct a population census and provide health services for all elephants in human care in Chiang Mai. The 2025 event took place over the last two weeks of January and involved collaboration between the Center of Elephant Research and Health Service under the Division of Animal Welfare and Veterinary Service of the Department of Livestock Development, the Thai Elephant Conservation Center (TECC), and the Center of Elephant and Wildlife Health at Chiang Mai University. The event focused on conducting a population census, performing health checks, providing antiparasitic treatments, vitamins, and basic medical supplies to the elephants.

During the census, the team did not finalize a summary of the total number of elephants in Chiang Mai yet, but the estimate seems to be approximately same as last year, around 830-870. Most of the elephants were in good body condition. A few had minor health issues, for which the team provided recommendations and guidance to their owners and mahouts. Most of the health issues noted were dry eyes and skin. This year, the team was excited to also meet many newborn elephants in both Mae Wang and Mae Tang areas.

The few cases during the beginning of the month were on the milder side. There were a couple of gastrointestinal discomfort cases, an eye irritation case, and a couple of wounds requiring therapy and care.

The owner of a middle-aged female elephant who was presenting with excessive tears from her eyes contacted the CMU Mobile Vet Team. She said that she had tried to clean the eyes and apply eye drops for a week but it was not better. Upon the examination, the elephant’s face was covered with the red dirt and excessive tears showed on both eyes. The right eye was found to have a cloudy scar on the cornea, whereas the left eye showed mild cloudy and more excessive tear. The vets cleaned the eyes then, fluorescein staining was done to ensure there were no obvious ulcers. It was suggested the elephant be kept in a shaded area, the eye rinsed several times, and a non-steroidal anti-inflammatory drug applied.

One of the wounds being cared for was an older wound from last month that was still requiring treatment. While the wound showed significant improvement, it had not yet fully healed, so laser treatment remained ongoing.

The second wound was a ruptured mass on the elephant’s left elbow. The owner was unsure about wound care. The mass was large, firm, and had a thin, ruptured center. The wound was cleaned with saline and an antiseptic solution, followed by alcohol and povidone-iodine applications. Then the wound was widened with a small incision to improve drainage and cleaning. Given the risk of infection, the vet advised the owner and mahout to clean the wound regularly and apply antibiotic ointment until it healed.

The third wound was a mother elephant with bleeding at her teat. Her 1.5-month-old calf had started teething and unintentionally injured her nipple while nursing. Upon examination, a fresh wound on her right nipple was found, but the bleeding had stopped, and milk flow remained unaffected. The mother did not resist nursing on either side. The mahout was advised to clean the wound only with saline, drying it with a clean cloth, and avoiding any medication to ensure safe nursing for the calf.

CMU Mobile Vet Clinic Updates

New beginnings for the new year seems like the perfect theme for this update from Thailand. So, what better way to start the new year than with news from the Chiang Mai University (CMU) Mobile Vet Clinic team than to talk about babies and the future elephant vets of the world? The roster of the month also included some of the more typical calls like gastrointestinal upset, stiffness, abscesses, and wound care which kept the team busy. Thanks to the team with the CMU Mobile Vet Clinic for all they are doing to improve the lives of elephants now and into the future.

The vet staff of the center and the Thai Elephant Conservation Center (TECC) welcomed and facilitated vet students from Ohio State University in a short training program about elephant medicine at TECC on December 19-20. They discussed topics of management and welfare in 4 groups of elephants. The students got to practice a full physical examination of elephants, and they also learned and practiced medical treatment with cases at the elephant hospital under the supervision of a professional veterinarian as well. This program provided a good opportunity for experiencing to vet students about Asian elephants.

On December 10, the veterinarian received a call at 3 AM about a new mother elephant showing signs of labor. She gave birth to a healthy male calf at 5:50 AM. Although the calf was strong, the new mother reacted aggressively toward him. The team quickly stepped in to assist, restraining the mother and gradually introducing the calf to her. The placenta had not yet been expelled, and the mother was still agitated when the team attempted to bring the baby to nurse. After 4 hours, the veterinarian administered an oxytocin injection to help the mother expel the placenta and stimulate milk letdown. The team and the vets tried introducing the calf to mom over and over every 30 minutes to 1 hour all day long without much luck. They even started manually milking mom when presenting the calf. Fortunately, by the next morning, nearly 24 hours after birth, the mother had learned to accept the calf and allow him to nurse. The following day when the vets followed up on the calf, they found that he was staying close to his mother and successfully nursing.

The veterinarian examined a calf born in November whose mother had a mammary teat defect. The left teat was atrophied, while the right teat was abnormally shaped, making it difficult for the calf to nurse. A few days later, the mother showed signs of agalactia (reduced milk production and letdown). Both the mother and calf were sent to the foundation hospital in Lampang for care. After two weeks, they returned to the camp. The camp vet and the owner requested the CMU mobile vet team to monitor the calf’s health. Upon arrival, they found the calf walking at the forest’s edge with his mother and the herd. The calf was alert, but was very small and thin. It was recommended to keep them in an enclosure to allow the calf to nurse more frequently and get adequate rest.

The owner of an elephant in Mae Wang contacted the CMU mobile vet regarding a newborn calf, which was born on December 10 at 5:35 PM. By the following morning, the calf had not been able to nurse. While the mother elephant did not harm the baby, the calf was unable to find the teat. Due to the lack of sucking or stimulation, the mother’s milk production was reduced. The veterinarian examined both the mother and calf, and they were both healthy. The vet administered the oxytocin to the mother to promote the milk letdown. In addition, the vet recommended that the calf be brought to the mother for milking at least once every hour. After nearly a full day, the mahout reported that the calf still could not nurse. They sought advice on hand-rearing the calf to prevent starvation and weakness. Happily, after 2-3 days the calf was able to nurse on his own.

CMU Mobile Vet Clinic Updates

November was a very busy month for the CMU Mobile Vet team. There were over a dozen cases with several of them requiring follow-up visits. From the typical cases dealing with wounds and gastrointestinal issues to support for musth bull management and pregnant females.

Early in the month, the team was called to treat a 21-month-old calf with gastrointestinal discomfort and parasites in her fecals. To be safe, the calf was tested for EEHV. Gratefully, after a negative test result, the administration of a non-steroidal anti-inflammatory drug, an anti-parasitic medication, and a three-day course of deworming medication the calf’s condition improved and her feces returned to normal. Later in the month, the vets received a call regarding a 52-year-old cow with digestive discomfort. The mahout reported that she hadn’t defecated yet, had laid down twice, and refused to eat. A full history showed she had a history of digestive issues, including the discovery of a small piece of tooth, and her feces had been consistently large and coarse. After fluids, transrectal palpation, and plenty of supportive care the cow was feeling better. The vets instructed the mahout on food management, suggesting chopped grass mixed with pellets, and the cow ate well.

On two separate occasions, the CMU Mobile Vets were called to help support the relocation of two musthy bulls. While each case was different, both bulls needed to be sedated to assist in their safe transfer to areas better equipped to manage each bull during their musth season for their safety, as well as, the safety of the mahouts and other elephants. Musth bulls can be extremely challenging and dangerous to work with. Thankfully, the CMU Mobile Vets were able to aid mahouts for good outcomes!

Several of the cases over the course of the month involved the ups and downs of pregnancy in elephants. The CMU Mobile Clinic vets were called in to assist in ultrasounds on two cows. The team could not visualize the calf in one case, probably due to mom’s large size. In the other instance, the vets were able to assess the condition of a cow experiencing dystocia. They were able to visualize the rib cage of the fetus, but were unable to detect a heartbeat. The mother had labored on and off for a couple days and had made no progress; she passed the deceased fetus a week later. Happily, at the end of the month the vets were called to a remote area in Mae Wang to check on a mom and her newborn calf who had been born early that morning at 3 am. All was well with mom and baby. The little girl was strong and already nursing well.

Update! Rescued baby Sumatran elephant


A few months ago, we shared information that our field partners in Sumatra, the Veterinarians from the Wildlife Ambulance, were asked to provide veterinary expertise for the treatment and rescue of an abandoned sick wild elephant calf in Aceh province.

A herd of elephants had raided agricultural crops where farmers had a small storage hut for equipment and fertilizers. The elephants destroyed some of the bags of fertilizer. It appeared that the calf had likely consumed some of the fertilizer causing severe gastrointestinal illness.  The calf had rubbed his eyes with its fertilizer contaminated trunk causing significant eye inflammation and corneal ulcers. While stumbling around blind, the calf also sustained some abrasive wounds on his body.  The calf was unable to follow the herd and needed intense treatment, so the decision was made to rescue the calf and bring it to camp for treatment and monitoring.

The calf, named Gary, is now doing very well and has recovered from the abrasive wounds. He is blind in one eye but has adapted well to slightly diminished eyesight.

We are grateful for the efforts of the Veterinarians of the Wildlife Ambulance and the field staff who work tirelessly to provide medical care for critically endangered Sumatran elephants and other wildlife.

CMU Mobile Vet Clinic October Updates

 In early October, heavy rains caused significant water flow from remote areas into the Mae Tang River, leading to a sharp rise in the river’s water level. Many elephant camps, located near the river, experienced flooding. Most camps were prepared and had moved elephants from high-risk areas to higher ground for safety. October 4 marked the peak of the flooding, when access to Mae Tang was cut off, and only boats could navigate through. Fortunately, the water level began to recede the next day, allowing cars to pass, though the routes remained challenging due to mud.

Numerous organizations, including the Department of Livestock Development (DLD), the Thai Elephant Conservation Center (TECC), the Department of National Parks (DNP), and various government and private sectors, provided assistance to the affected elephant camps. The Chiang Mai University (CMU) vet team collaborated with DLD, DNP, and TECC veterinarians to conduct a population count in a large camp where elephants had been dispersed due to the flooding. They also advised on essential plans for proper management and care for the elephants during the flooding event.

During the post-disaster recovery period, the CMU vet team and the TECC veterinary team provided targeted veterinary services for elephants in Mae Tang. The visit aimed to monitor elephant health, collect samples for testing flooding-related diseases (such as leptospirosis and parasitic infections), and administer deworming medication. From their field visits, the team observed that each camp was undergoing reconstruction. Most elephants were safe and food supplies were largely unaffected, thanks to the support from various organizations and individuals who provided elephant food and supplements.
