Data collection related to farrowing performances and health parameters was performed in 20 intensive pig farms in Portugal (100-800 sows each) over 7 yr (1985-1992). At-risk profiles were obtained regarding the metritis-mastitis-agalaxia (MMA) syndrome. Using prospective surveys and subsequent preventive veterinary medicine programs in pig farms, the profile of 347 sows was analyzed by multidimensional statistical methods, and we demonstrated the value of risk-factor analysis to fight this enzootic problem. We observed a decrease in the prevalence of MMA syndrome, an increase in piglet survival and in the number of weaned piglets per sow, and a decrease in sow mortality rate. Our studies have shown the value of risk-factor analysis to fight enzootic disorders.
1985年至1992年的7年间，在葡萄牙的20个集约化养猪场（每个猪场有100 - 800头母猪）收集了与产仔性能和健康参数相关的数据。获得了有关子宫炎-乳房炎-无乳综合征（MMA）的风险概况。通过在猪场进行前瞻性调查和随后的预防性兽医学计划，采用多维统计方法分析了347头母猪的概况，并且我们证明了风险因素分析对于应对这一地方病问题的价值。我们观察到MMA综合征的患病率下降,仔猪存活率和每头母猪断奶仔猪数量增加，以及母猪死亡率下降。我们的研究表明了风险因素分析对于应对地方病的价值。
