Oral administration of altrenogest for oestrus suppression in competition horses is believed to be widespread in some equestrian disciplines, and can be administered continuously for several months during a competition season. To examine whether altrenogest has any anabolic or other potential performance enhancing properties that may give a horse an unfair advantage, we examined the effect of oral altrenogest (0.044 mg/kg), given daily for a period of eight weeks, on social hierarchy, activity budget, body-mass and body condition score of 12 sedentary mares. It was concluded that prolonged oral administration of altrenogest at recommended dose rate to sedentary mares had no effect on dominance hierarchies, body-mass or condition score.
在一些马术项目中，口服烯丙孕素抑制竞赛用马发情的做法据信十分普遍，并且在竞赛季节可连续服用数月。为研究烯丙孕素是否具有任何合成代谢或其他可能增强马匹性能的潜在特性从而使马匹获得不公平优势，我们对12匹非运动型母马进行了研究，观察连续八周每日口服烯丙孕素（0.044毫克/千克）对其社会等级、活动预算、体重和身体状况评分的影响。研究得出结论，以推荐剂量率对非运动型母马长期口服烯丙孕素，对其优势等级、体重或身体状况评分没有影响。
