Rafiki's Calf is stillborn [more info]
Rafiki, one of our two female African elephants impregnated through artificial insemination, gave birth on July 27 to a stillborn male calf. The calf was exceptionally large, weighing approximately 350 pounds. On average, newborn elephant calves weigh around 200-250 pounds. According to Dr. Dennis Schmitt, Elephant Reproductive Specialist, it appeared that the calf had difficulty clearing the birth canal due to its size. This was later verified by a necropsy. The Q&A will help to explain what we've already learned from this sad turn of events and where The Toledo Zoo's elephant breeding program will go from here.

Q:

Considering the risks associated with captive elephant births, why breed elephants at all?

A:

Because the captive population of female African elephants is aging, there are fewer and fewer individuals of breeding age left. It's critical to attempt to breed this threatened species while at least some reproductively viable elephants remain.

Also, captive elephants serve as ambassadors for their species. To save the elephant, we must also save its natural habitat. Elephants born in captivity will remain in captivity to help get this message across to people.

Q:

How is Rafiki's health after the stillbirth? 

A:

Rafiki is doing very well. The exceptionally large calf she delivered could have jeopardized her health, but she came through the birth with no complications. We attribute this to the exercise and nutrition program Rafiki and Renee have been on since before they conceived, which put her in excellent physical condition for delivery.

more questions

Q: How is the Zoo staff taking the stillbirth of Rafiki's calf?
A: Even though the staff was well aware of the risks associated with captive elephant births and was confident that everything had been done to facilitate a successful delivery, the loss of Rafiki's calf is a source of great sorrow.

more questions
Q: Why was the calf so large?
A:

This is not yet fully understood. The calf's size may have been due simply to normal variation, as one might expect among human infants. For example, one human baby might weigh 6.5 pounds at birth, another might weigh 9 pounds, and still another might weigh 11 pounds.

Another possible explanation is that Rafiki is relatively large herself (she's noticeably taller than Renee even though Renee is actually the older of the two) and may tend to produce larger-than-average calves.

more questions

Q: Would you have done anything differently?
A: No. We believe that we did everything within our control to facilitate a successful birth. In fact, Dr. Tim Reichard, The Toledo Zoo's Director of Animal Health and Nutrition, believes that the way the birth took place and the outcome were very similar to what would have happened in the wild.

more questions
Q: After this experience, will you alter the plans for Renee's delivery?
A: Our approach to Renee's delivery will not change due to the stillbirth of Rafiki's calf. Preparation for the birth began many months in advance, including placing Rafiki and Renee on a special diet and exercise regimen. Though we are greatly saddened by the loss of the calf, everyone here at the Zoo is grateful that Rafiki is in good condition and that no member of our elephant team was harmed during the birth.

more questions
Q: If the birth had taken place inside or the labor hadn't progressed so rapidly, would you have been able to save the calf?
A: We believe that the stillbirth was due to the large size of the calf and was not related to the timing or location of the delivery.

more questions
Q: Couldn't you have performed a Caesarean section to save the calf?
A: C-sections have only been attempted a few times on elephants. In each case, the mother did not survive the procedure. We decided during the research stage that we would not put Rafiki's life in jeopardy by performing a C-section. The only circumstance under which a C-section would have been attempted would have been if Rafiki's death was imminent and it was the only way to save the calf.

more questions
Q: Will another artificial insemination be attempted on Rafiki?
A: Our priority now is to continue Renee's prenatal program and to focus on her upcoming birth. Once we've reached that milestone, we will re-evaluate future breeding attempts.

more questions
Q: Will the calf, though stillborn, somehow serve the cause of elephant conservation?
A: Even though we didn't get the outcome we hoped for with the birth of Rafiki's calf, the entire process leading up to the birth has contributed significantly to the future of elephant breeding and the conservation of this species. The Toledo Zoo knew the risks associated with captive elephant births, yet we chose to assume those risks so that we could share the knowledge and experience gained through the process with other institutions.
