A Rapid Technique for Observing the Reproductive Tract of Living Ewes

Abstract

A laparotomy technique using a plastic speculum for rapidly and accurately observing ovarian structures within the peritoneal cavity of the ewe is described. This technique is used in conjunction with a new laparotomy restraining device (LRD) developed to reduce labor and to make the entire operation more efficient. This method is rapid and accurate, and reduces traumatization, dehydration and bacterial contamination of the reproductive tract. This improved technique appears to reduce adhesions to a negligible level and makes practical the selection of ewes on the basis of ovulation rate.
