Data concerning frequencies of 17 main diseases in 59 dairy farms from continual eco-pathological survey, are analyzed by classical regression test, principal components analysis and analysis of variance. Thirty-three statistical relations (positive simple correlations) are shown. Clinical mastitis and retained placenta are associated to nine diseases each, metritis, stillbirth and non-infectious foot disorders to six, dystocia and infectious foot disorders to four, pathology of calf and abortion to three, mammary edema and appetite disorders to two. Ovarian pathology, digestive disorders and teat lesions are "isolated", being associated to only one other disease. The pathological frequencies in dairy farms seem to change in the same way, indicating the existence of common risk factors, and leading to propose a global hygienic prevention. The pathological associations allow to definite some groups of dairy farms showing one or other dominant pathological complex. In the frame of our sample of dairy farms, two groups seem to be determined: one with calving disorders and calf pathology centred on retained placenta, the other with foot disorders, infectious and metabolic troubles, centred on mastitis, as dominant diseases.
通过连续生态病理学调查收集了59个奶牛场17种主要疾病的发病频率数据，并采用经典回归检验、主成分分析和方差分析进行分析。结果显示了33种统计关系（正简单相关性）。临床乳腺炎和胎衣不下各与9种疾病相关，子宫内膜炎、死胎和非感染性蹄病与6种疾病相关，难产和感染性蹄病与4种疾病相关，犊牛病理学和流产与3种疾病相关，乳房水肿和食欲障碍与2种疾病相关。卵巢病理学、消化系统疾病和乳头病变是“孤立的”，仅与另一种疾病相关。奶牛场的发病频率似乎以相同的方式变化，表明存在共同的风险因素，因此建议采取全面的卫生预防措施。这些病理关联有助于确定一些表现出一种或另一种主要病理复合体的奶牛场群体。在我们的奶牛场样本中，似乎可以确定两组：一组以产犊障碍和以胎衣不下为中心的犊牛病理学为主，另一组以蹄病、感染性和代谢性疾病为主，以乳腺炎为主要疾病。
