Abstract
Pregnancy diagnosis by ultrasonography was performed for both pregnant and non-pregnant Asiatic black bears which were being under hibernation. Pregnancy was diagnosed for a pregnant bear by detecting images of heart-beat and vertebrae on ultrasonograph. Serum progesterone levels were measured for both pregnant and non-pregnant bears. The level of serum progesterone was 5.79 ng/ml for a pregnant bear and 0.76 ng/ml for a non-pregnant bear, respectively, thereby it was considered that measurement of serum progesterone level can be also useful for pregnancy diagnosis for Asiatic black bear.
