Title: Pregnancy Diagnosis in the Ewe I. Rectal-Abdominal Palpation
Author: Weigl, Robert M.; Tilton, J. E.; Light, Merle R.; Haugse, C. N.; Buchanan, M. L.
Description: The detection of pregnancies in farm animals has been a topic of interest for decades. One way to improve reproductive efficiency would be to eliminate non-pregnant females ahead of the lambing season. Early detection of open ewes would allow for re-breeding or possibly reveal any existing breeding problems in males. Improved feed utilization and more efficient use. of a!1 facilities could be made. Also, considerable savings in feed could be realized If single-bearing ewes were fed separately from multiple-bearing ewes. The objectives of the study discussed in this article were: to assess the accuracy of pregnancy detection by rectal abdominal palpation, to evaluate the stage of pregnancy and size of ewe on the accuracy of the pregnancy detection and fetal number evaluation and, finally, to To'determine the feasibility of separating ewes into feeding groups based on the prediction of fetal numbers they were carrying. In conclusion, based upon actual field testing, rectal-abdominal palpation offers an acceptable means of diagnosing pregnancy in ewes. The technique is simple and can be quickly performed.
