One thousand reproductive organs from gilts were collected during the period March-August at a slaughterhouse in central Sweden. The organs were inspected in respect of congenital defects and certain reproductive physiological data. The results are recorded in Tables 1–6. Figs. 1–7 show some types of malformations. The total frequency of malformations was 22.1 %, of which 14 % cysts in mesosalpinx and 4.1 % partial duplication of the vagina. The remainder consisted of general developmental defects and of local defects in the tubular genital tract. Malformations with presumed effect on fertility were found in 4.5 % of all organs examined, of which 0.8 % presumably caused permanent sterility and 3.7 % lowered fertility (small litters). Hydrometra was found in 33 cases, 2 of which in sexually mature gilts. The left ovary contained more corpora lutea than the right, and the mean weight of the left ovary was greater than that of the right, both in sexually mature and prepuberal gilts. Of 202 sexually mature gilts examined 16.9 % had cystic corpora lutea in their ovaries as a rule 2–4 in each ovary.
在瑞典中部的一家屠宰场，于3月至8月期间采集了1000头后备母猪的生殖器官。对这些器官进行了先天性缺陷检查以及某些生殖生理数据的记录。结果记录在表1 - 6中。图1 - 7展示了一些类型的畸形。畸形的总发生率为22.1%，其中输卵管系膜囊肿占14%，阴道部分重复占4.1%。其余包括一般发育缺陷和管状生殖道的局部缺陷。在所检查的所有器官中，发现有4.5%的畸形可能会影响生育能力，其中0.8%可能导致永久性不育，3.7%会降低生育能力（产仔数少）。发现有33例子宫积水，其中2例发生在性成熟的后备母猪中。无论是性成熟的还是青春期前的后备母猪，左侧卵巢的黄体数量都多于右侧，且左侧卵巢的平均重量大于右侧。在检查的202头性成熟后备母猪中，16.9%的母猪卵巢中有黄体囊肿，通常每个卵巢有2 - 4个。
