Modern portable ultrasound machines provide the veterinary clinician with an inexpensive and non-invasive method to further examine the reproductive tract of both male and female sheep on farm which should take no more than 5 min with the results available immediately. Unlike cattle, ultrasound examination of the ovaries is not undertaken because failure to cycle during the normal season is rare in sheep and there are no common ovarian conditions causing acyclicity. Accurate diagnosis of foetal number has greatly improved the nutritional management of late gestation ewes over the past 30 years. Late gestation nutritional supply in response to foetal demand greatly reduces perinatal lamb mortality by ensuring lamb birthweight and ewe colostrum accumulation. The contents of vaginal prolapse have been determined using ultrasonography which has led to an improved method for correction. A retained foetus when second stage labour is considered to have been completed, and uterine torsion, can be identified during ultrasound examination allowing timely correction. Ultrasonographic examination of palpable scrotal abnormalities can provide much useful information particularly in the diagnosis of epididymitis, orchitis and testicular atrophy.
现代便携式超声机为兽医临床医生提供了一种廉价且非侵入性的方法，可在农场对雄性和雌性绵羊的生殖道进行进一步检查，整个过程应不超过 5 分钟，且结果可立即获得。与牛不同，不会对卵巢进行超声检查，因为绵羊在正常季节很少出现不发情的情况，而且没有常见的卵巢疾病会导致不发情。在过去的 30 年中，准确诊断胎儿数量极大地改善了妊娠后期母羊的营养管理。根据胎儿的需求提供妊娠后期的营养供应，通过确保羔羊出生体重和母羊初乳的积累，大大降低了围产期羔羊的死亡率。已经使用超声检查确定了阴道脱垂物的内容物，这导致了一种改进的矫正方法。当第二产程被认为已经完成时，如果发现有胎儿滞留和子宫扭转，可以通过超声检查来识别，以便及时进行矫正。对可触及的阴囊异常进行超声检查可以提供许多有用的信息，特别是在诊断附睾炎、睾丸炎和睾丸萎缩方面。
