A study was conducted at Debre Zeit export abattoir on 404 bucks belonging to four breeds and 167 rams of two breeds. The animals were selected from the slaughter flock using stratified sampling based on breed. Ante-mortem and post-mortem examinations were carried out after each animal was carefully identified. Various genital abnormalities were observed, among which testicular atrophy and epididymitis were the predominant genital problems in both bucks and rams. The prevalence of cryptorchidism was higher (p<0.05) in bucks than in rams, while epididymitis (p<0.05), sperm granuloma (p<0.01) and epididymal cysts (p<0.05) were more frequent in rams. In bucks, none of these abnormalities was significantly associated with age (p>0.05). However, testicular atrophy (p<0.01), epididymitis (p<0.01) and haemorrhagic lesions (p<0.05) were associated with breed, the prevalence being higher in Woito-Guji and Boran bucks than in the Arsi-Bale and Afar breeds. In rams, age affected (p<0.05) the incidence of testicular atrophy, epididymitis and sperm granulomas. Epididymitis, sperm granuloma and epididymal cysts were more frequent (p<0.01) in Adal rams than in Black Head Somalis.
在德布雷齐特出口屠宰场对属于四个品种的404只公山羊和两个品种的167只公羊进行了一项研究。这些动物是从屠宰畜群中按品种采用分层抽样法挑选出来的。每只动物经过仔细识别后进行宰前和宰后检查。观察到各种生殖器官异常，其中睾丸萎缩和附睾炎是公山羊和公羊中主要的生殖问题。隐睾症在公山羊中的患病率高于公羊（p<0.05），而附睾炎（p<0.05）、精子肉芽肿（p<0.01）和附睾囊肿（p<0.05）在公羊中更为常见。在公山羊中，这些异常均与年龄无显著关联（p>0.05）。然而，睾丸萎缩（p<0.01）、附睾炎（p<0.01）和出血性病变（p<0.05）与品种有关，沃伊托-古吉和博拉纳公山羊的患病率高于阿尔西-巴勒和阿法尔品种。在公羊中，年龄影响（p<0.05）睾丸萎缩、附睾炎和精子肉芽肿的发生率。阿达勒公羊的附睾炎、精子肉芽肿和附睾囊肿比黑头索马里公羊更为常见（p<0.01）。
