The effect of a ram-pheromome extracted from the wool of insemination rams with excellent libido sexualis of the merino mutton sheep breed was examined with respect to the hormonal secretion and fertility of adult ewes during the breeding season. A control group (untreated animals) was at disposal for every experiment. There were significant differences between the ewes treated with pheromone and the controls in the course of the preovulatory LH wave and the oestradiol concentration of the oestrus sheep at the beginning of the breeding season. The ovulation in ewes after prostaglandin application was stimulated by pheromone applications. The regime practised in the experiment on pherome application had a positive influence on the conception rate of the inseminated ewes and resulted in a significant increase of the lambing results (lambs/birth).
研究了从美利奴肉羊品种中具有优良性欲的授精公羊羊毛中提取的一种公羊信息素对繁殖季节成年母羊激素分泌和生育能力的影响。每次实验都设有一个对照组（未处理的动物）。在繁殖季节开始时，用信息素处理的母羊与对照组在排卵前促黄体生成素（LH）波过程以及发情母羊的雌二醇浓度方面存在显著差异。应用前列腺素后，母羊的排卵受到信息素应用的刺激。实验中采用的信息素应用方案对授精母羊的受孕率有积极影响，并导致产羔结果（羔羊/分娩）显著增加。
