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. The LRD has a horizontal loading and unloading position. It is easily raised to a 65[degree] or 70[degree] angle for operating. 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.
