Abstract: | Seven deliveries of rhesus monkeys maintained in the laboratory were recorded by a video recorder system to determine the
signs of impending labor. The characteristic postures; i.e., standing, squatting and crouching, were demonstrated in all cases
with cyclic regularity (about 2–4 min) 35–210 min prior to the actual parturition, although prediction of the delivery date
several days beforehand failed. The four stages of the delivery process are also presented in this report. |
