A survey of reproductive tracts from nonpregnant cows at an abattoir was conducted. Reproductive tracts from 98 cows were studied microscopically and evaluated with a grading system to determine the severity of pathologic changes. Inflammatory reaction (type and distribution), fibrosis, gland morphology, and appearance were measured, quantified, and scored (1 to 4). Category 1 endometrium (normal) was found in 18 cows, category 2 in 23, category 3 in 34, and category 4 in 23. The category of endometrium was then compared with the retrospective reproductive status, and it was found that reproductive problems had occurred in 6 cows (33.3%) in category 1, in 13 cows (56.5%) in category 2, in 25 cows (73.5%) in category 3, and in 21 cows (91.3%) in category 4. Cervicitis was found in 43 (43.8%) genital tracts; 16 cows (16.3%) had salpingitis. Ovarian lesions were not observed. Serum samples were tested for certain antibodies. Only 1 was seropositive for brucellosis, but 61 of 81 sera had leptospira titers greater than 1:100 and 1:50 (hardjo). The serovar hardjo was the most prevalent. All sera had neutralizing titers against parainfluenza type 3 virus; 74.2% and 56.7% of the sera had neutralizing antibodies against bovine viral diarrhea virus and infectious bovine rhinotracheitis virus, respectively.
对一家屠宰场未怀孕母牛的生殖道进行了调查。对98头母牛的生殖道进行了显微镜检查，并采用分级系统进行评估，以确定病理变化的严重程度。对炎症反应（类型和分布）、纤维化、腺体形态和外观进行了测量、量化并评分（1至4分）。18头母牛的子宫内膜为1级（正常），23头为2级，34头为3级，23头为4级。然后将子宫内膜类别与回顾性生殖状况进行比较，发现1级中有6头母牛（33.3%）出现生殖问题，2级中有13头母牛（56.5%），3级中有25头母牛（73.5%），4级中有21头母牛（91.3%）。在43条（43.8%）生殖道中发现宫颈炎；16头母牛（16.3%）患有输卵管炎。未观察到卵巢病变。对血清样本进行了某些抗体检测。只有1份布鲁氏菌病血清呈阳性，但81份血清中有61份钩端螺旋体滴度大于1:100和1:50（哈德焦型）。哈德焦血清型最为常见。所有血清对3型副流感病毒均有中和滴度；分别有74.2%和56.7%的血清对牛病毒性腹泻病毒和传染性牛鼻气管炎病毒有中和抗体。
