Diagnostic imaging in Linnaeus's two-toed sloth (Choloepus didactylus) – pregnancy diagnosis and fetometry

Purpose: The knowledge of the reproductive physiology and biology of the two-toed sloth is fragmentary at best. So the data of the gestation period in the literature vary from 150 to 322 days. This study is intended to demonstrate the pregnancy diagnosis and the fetometry in the two-toed sloth with ultrasonography. Material and methods: The ultrasound investigations to visualize the genital system in this species can be performed transcutaneous or transrectal. Only the transcutaneous examinations can be performed without immobilization, if the animals are in medical training. The transcutaneous pregnancy examina…
