Abstract

Forty-six mares mated from 16 to 58 days prior to examination, were scanned using a linear-array ultrasound scanner (ALOHA ECHO CAMERA SSD-210, DX ll) with a 5 MHz transrectal transducer. For 16 animals images were made on thermopaper using an electronic printer (MITSUBISHI VIDEO COPY AP-8600). The pregnancy diagnosis was accurate in 100% of cases. The pregnancy was detected at the earliest period on the 16th day, when the embryonic vesicle with embryonic fluid was seen on the screen. From the 24th and 25th day, besides embryonic vesicle with fluid, we observed an embryo within the vesicle. In later pregnancy stages our estimation was based upon the foetal growth rate and positon of the foetus and the foetal membranes.
