Abstract
Real-time ultrasonic scanning can be used to diagnose pregnancy and determine foetal numbers in sheep, goats and cattle, and has advantages over other approaches in terms of safety, accuracy and rapidity. In sheep and goats the principal benefits of the use of the technique include the ability to relate feed inputs in late pregnancy to foetal numbers, thus improving the efficiency of use of feedstuffs. Feeding in relation to foetal numbers also offers a means of manipulating birthweights and can lead to substantial reductions in mortality of both offspring and their dams. In cattle real-time scanning can also be used to estimate foetal age with a high degree of accuracy thus enabling cows to be managed more efficiently in relation to expected date of calving.
