In twenty ewes of the Slovak Merino breed coming from a demonstration farm at Zemplínska Teplica, to the age of two-three years biometrical variations of the sex organs and overall follicular response to PMSG and PGF2 alpha administration were investigated in the autumn period (October-November). In the ewes of all groups the heat was synchronized by i. m. administration of PGF2 alpha (Oestrophan Spofa) at a dose of 125 micrograms in the interval of 11 days. On the ninth day the ewes of the second and fourth group were given 1000 i. u. of PMSG (Antex Leo, Denmark), the ewes of the third group 750 i. u. of PMSG. The ewes of the third and fourth group were administered at the same time 50,000 i. u. vitamin A (Axerophtol Spofa) (each group). The weight and dimensions of the sex organs were investigated. The results demonstrate that the administration of PMSG in the mating period increases significantly the weight of oviducts and horns of uterus in the ewes while there are no variations of the weight of the other sex organs and of their length, or it is lower than in the ewes of the control group. The overall follicular response was not influenced by the higher weight of ovaries.
在来自日利纳州特普利采示范农场的20只斯洛伐克美利奴品种母羊中，在秋季（10月至11月）对两到三岁母羊的性器官生物特征变化以及对孕马血清促性腺激素（PMSG）和前列腺素F2α给药的整体卵泡反应进行了研究。在所有组的母羊中，通过每11天肌肉注射125微克的前列腺素F2α（Oestrophan Spofa）来同步发情。在第9天，第二组和第四组的母羊注射1000国际单位的孕马血清促性腺激素（丹麦Antex Leo），第三组的母羊注射750国际单位的孕马血清促性腺激素。第三组和第四组的母羊同时注射50,000国际单位的维生素A（Axerophtol Spofa）（每组）。对性器官的重量和尺寸进行了研究。结果表明，在交配期注射孕马血清促性腺激素可显著增加母羊输卵管和子宫角的重量，而其他性器官的重量及其长度没有变化，或者低于对照组母羊。较高的卵巢重量并未影响整体卵泡反应。
