Some observations on the local use of ultrasound uterine scanning in thoroughbred stud veterinary practice

Abstract

Sir:— At the Reproduction Conference in Auckland, February 1982, Dr Allen presented a paper describing a new technique whereby the pregnancy status of the uterus could be determined as early as 22 days from service (in some cases earlier). During the 1982 breeding season we were able to use the Fisher Vetscan machine for early pregnancy diagnosis.
