Study on the introduction of ultrasonic techniques in sows

A survey of 45 farmers participating in a trial scheme using ultrasound to diagnose pregnancy (30 farmers replied) indicated that 17 farmers used ultrasound because sows returned to oestrus during pregnancy. Most of the others used it due to previous sow fertility problems, and 5 used it out of curiosity. 10% of sows were examined by ultrasound twice, and 0.5% three times. The interval between examinations was considered appropriate in 20 of 29 herds.
