Objectivisation of the physiological course of puerpery and control of involution processes of uterus represent topical questions of an increased frequency of lambing. Our study was directed at the determination of the weight, length of body and horns of uterus as well as of the weight, length, width and height of ovaries, following the administration of carbetocin (Depotocin inj. Spofa), in the puerperal period of Slovak Merino sheep. The study was aimed at obtaining objective biometric data on uterus and ovaries and recording the influence of carbetocin on the involution of uterus and ovaries of sheep. Thirty ewes, divided into two groups, were included in the experiment. The animals of the experimental group (n = 15) were subjected to treatment with carbetocin (Depotocin inj. Spofa) at the amount 2 x 0.07 mg. The first dose was applied intramuscularly (i. m.) on the 2nd day after parturition and the second dose was injected subcutaneously (s.c.) on the 4th day after lambing. The second group (n = 15) served as a control. Three ewes (n = 3) were bled on each of the following days: 1, 7, 17, 25 and 34 after parturition. After bleeding the sexual organs were removed by excision and their weight and the length of the body and horns of uterus and of ovaries was determined. The number and size of follicles were determined on the surface of ovaries. The weight of uterus body showed a declining tendency in sheep of the control group with a statistically significant decrease from the 17th till the 34th day after parturition (P less than 0.01). Its weight varied from 56.0-14.6 to 5.2-0.3 g in the above-mentioned time interval. The experimental group showed a statistically significant decrease in weight as early as on the 7th day after lambing compared to the 1st day after parturition, down to the values 185.66-38.91 g (P less than 0.05). The decrease in the weight of uterus body recorded on day 17 (106.56-41.08 g) was less pronounced than in the control group. The final average weight of the body of uterus on the 34th day after parturition was 41.36-8.52 g, that means higher than in the control group (5.2-0.3 g). The weight of gravid horns in the experimental group declined significantly as early as on the 7th day after parturition to the average weight of 60.89-9.45 g and reached 9.86-3.49 g on the 34th day.(ABSTRACT TRUNCATED AT 400 WORDS)
产褥期生理过程的客观化以及子宫复旧过程的控制是产羔频率增加的热门问题。我们的研究旨在确定斯洛伐克美利奴绵羊产褥期注射卡贝缩宫素（Depotocin inj. Spofa）后子宫的重量、体长和角长，以及卵巢的重量、长度、宽度和高度。该研究旨在获取子宫和卵巢的客观生物测量数据，并记录卡贝缩宫素对绵羊子宫和卵巢复旧的影响。实验纳入了30只母羊，分为两组。实验组（n = 15）用2×0.07毫克的卡贝缩宫素（Depotocin inj. Spofa）进行治疗。第一剂在分娩后第2天肌肉注射，第二剂在产羔后第4天皮下注射。第二组（n = 15）作为对照。在分娩后的第1、7、17、25和34天，每组各取3只母羊采血。采血后切除生殖器官，测定其重量以及子宫体和角以及卵巢的长度。测定卵巢表面卵泡的数量和大小。对照组母羊子宫体重量呈下降趋势，从分娩后第17天到第34天有统计学显著下降（P小于0.01）。在上述时间间隔内，其重量从56.0 - 14.6克变化到5.2 - 0.3克。与分娩后第1天相比，实验组在产羔后第7天子宫体重量就有统计学显著下降，降至185.66 - 38.91克（P小于0.05）。第17天记录的子宫体重量下降（106.56 - 41.08克）不如对照组明显。分娩后第34天子宫体的最终平均重量为41.36 - 8.52克，这意味着高于对照组（5.2 - 0.3克）。实验组妊娠角的重量在分娩后第7天就显著下降至平均重量60.89 - 9.45克，在第34天降至9.86 - 3.49克。（摘要截于400字）
