Pregnancy diagnosis in sheep using a rectal probe.
A total of 1823 ewes in three flocks was examined for pregnancy using a rectal-abdominal palpation technique. A correct diagnosis was made in 97 per cent of ewes with no evidence of ewe mortality or abortion. Ewes can be examined at the rate of 120 or more per hour. It is concluded that the technique is a simple, safe and reliable method of pregnancy diagnosis in sheep from 70 days of gestation.
