Postoperative performance and behavioral patterns were investigated retrospectively in 23 client-owned mares after bilateral ovariectomy via colpotomy. The interval from surgery to postoperative inquiries ranged from 9 to 67 months. Information obtained from review of the medical record and client interviews included the reason for ovariectomy, postoperative complications, problems identified by owners after discharge of the mare from the hospital, postoperative level of athletic performance, postoperative signs of estrus, and overall owner satisfaction. Reasons given by owners for having mares ovariectomized were behavioral modification (16 mares), use as embryo-transfer recipients (3 mares), use as mount mares for collecting semen (2 mares), elimination of chronic colic during estrus (1 mare), and sterilization for registration (1 mare). Postoperative complications developed in 4% (1/23) of the mares; however, problems were noticed by the owners of 4 other mares after discharge from the hospital. Continuing signs of behavioral estrus were detected in 35% (8/23) of the mares, but in only in 9% (2/23) was the behavior judged to be objectionable by the owner. Of 12 mares used in performance events prior to bilateral ovariectomy, 10 were judged to be competing at greater than preoperative levels, 1 was judged to be competing at the same level, and 1 was judged to be competing at less than preoperative level of performance. Of 18 owners, 14 were satisfied, 2 were undecided, and 2 were dissatisfied with their mare after it had had bilateral ovariectomy.
对23匹客户拥有的母马经阴道剖腹术进行双侧卵巢切除术后的表现和行为模式进行了回顾性研究。从手术到术后询问的时间间隔为9至67个月。从病历审查和客户访谈中获得的信息包括卵巢切除的原因、术后并发症、母马出院后主人发现的问题、术后运动表现水平、术后发情迹象以及主人的总体满意度。主人给出的母马卵巢切除原因包括行为改变(16匹母马)、用作胚胎移植受体(3匹母马)、用作采精的台马(2匹母马)、消除发情期慢性腹痛(1匹母马)以及为登记进行绝育(1匹母马)。4%(1/23)的母马出现术后并发症;然而,另外4匹母马的主人在母马出院后发现了问题。35%(8/23)的母马检测到持续的行为发情迹象,但只有9%(2/23)的行为被主人判定为令人反感。在双侧卵巢切除术前用于表演赛事的12匹母马中,10匹被判定比赛水平高于术前,1匹被判定比赛水平与术前相同,1匹被判定比赛水平低于术前。18位主人中,14位满意,2位不确定,2位对其母马双侧卵巢切除术后不满意。
