Abstract

The number of corpora lutea (CL) generated in superovulated ewes was assessed by laparoscopy and laparotomy. Forty-one Targhee-type ewes were superovulated with FSH during the breeding season, and bred by natural service to fertile rams. Five to six days later, the number of ovulations (CL) in anesthetized ewes were counted via laparoscope. A laparotomy was immediately performed on each ewe, and ovaries exteriorized for a definitive CL count. Correlation between CL counts at laparoscopy and laparotomy were high (r2 = 0.84, P < 0.001). Results suggest that laparoscopy can accurately estimate the number of CL in superovulated ewes, thereby avoiding major surgery in non-responding or poorly responding animals.
