Hormone help: Calgary Zoo hopes unusual step will result in healthy baby giraffe
CALGARY — Staff at the Calgary Zoo have adopted an extraordinary measure in an effort to ensure a pregnant giraffe becomes a mother for the first time.
Emara, a Masai giraffe, is expecting for the fourth time, but her previous pregnancies ended in two miscarriages and the death of a third calf with severe birth defects.
Emara’s fecal samples, collected after the calf died, indicated a decrease in her progesterone levels throughout her pregnancy.
The decline in the hormone is believed to have been the cause.
