Twenty-five heifers and cows with follicular cysts (high level of total oestrogens, low level of progesterone in plasma) were treated with 20 or 50 micrograms buserelin i.m. 5-84 weeks after parturition. Two hours after medication an increased LH release was observed in all animals. In contrast to LH, FSH concentration was not increased in all cows. Twelve days after treatment a high progesterone concentration in plasma could be determined in 17 of 25 treated animals. Twenty cows showed oestrous symptoms 23.5 +/- 9.6 days after medication. The oestrous cycle was prolonged in 10 cows. Nineteen cows were inseminated and 14 cows became pregnant after 1-4 (phi 1.7 +/- 0.9) inseminations (73.6% of all inseminated cows and 56% of all treated cows). The differences in conception rate and in services per conception after treatment with 20 or 50 micrograms buserelin in favour of the higher dosage cannot be attributed to the medication.
25头患有卵泡囊肿（血浆中总雌激素水平高、孕酮水平低）的小母牛和母牛在产后5 - 84周接受了20微克或50微克布舍瑞林的肌肉注射治疗。用药两小时后，所有动物的促黄体生成素（LH）释放均增加。与LH不同，并非所有母牛的促卵泡生成素（FSH）浓度都增加。治疗12天后，25头接受治疗的动物中有17头血浆中的孕酮浓度较高。20头母牛在用药后23.5±9.6天出现发情症状。10头母牛的发情周期延长。19头母牛接受了授精，14头母牛在1 - 4次（平均1.7±0.9次）授精后怀孕（占所有授精母牛的73.6%，占所有接受治疗母牛的56%）。用20微克或50微克布舍瑞林治疗后，受孕率和每次受孕所需授精次数的差异有利于较高剂量，但不能归因于药物治疗。
