Scan of the Porcine Uterus by Ultrasonic Scanning Device

Abstract

A portable ultrasonic linear electronic scanner was used for the detection of the uterus in pregnant sows. No images of the uterus were displayed in the scanned picture of non-pregnant or pregnant sows until day 18 of gestation. On the following day the images of the gravid uterus were first recognized. The gravid uterus increased remarkably in diameter on day 24 of gestation. Fetuses began to be detected in it on day 32 of gestation.
