Fifty Holstein dairy cows with palpable corpora lutea were divided into two groups. Twenty-five cows were given 500 micrograms of cloprostenol followed by 8 micrograms (2 mL) of buserelin, an analogue of gonadotropin-releasing hormone, and 25 were given cloprostenol followed by saline. Milk was collected for progesterone assay at the time of treatment and two days later. Differences in median progesterone concentrations before and following treatment were not significantly different between the saline and buserelin treated cows (p greater than 0.23).
50头有明显黄体的荷斯坦奶牛被分为两组。25头奶牛先注射500微克氯前列醇，随后注射8微克（2毫升）布舍瑞林（一种促性腺激素释放激素类似物），另外25头奶牛先注射氯前列醇，随后注射生理盐水。在治疗时及两天后采集牛奶进行孕酮测定。生理盐水组和布舍瑞林治疗组奶牛治疗前后孕酮浓度中位数的差异无统计学意义（p>0.23）。
