A computerised information retrieval system of broiler production data has been used to study the epidemiology of contact dermatitis. The results of the analyses of broiler production data for the period 1984/85 were compared and contrasted with those for the period 1986/1987. The prevalence of breast lesions recorded in the latter period was 33% less than in the former. The prevalence of hock lesions was similar in both periods, but the degree of variation in the prevalence of lesions recorded by individual flocks was substantially reduced in 1986/87. Stocking density, average age of removal and the sex of birds all had an effect on the prevalence of the condition in broiler flocks in both time periods. The condition was more frequently recorded in flocks during the winter and a strong correlation with ambient relative humidity, obtained.
一个肉鸡生产数据的计算机信息检索系统已被用于研究接触性皮炎的流行病学。对1984/85年期间肉鸡生产数据的分析结果与1986/1987年期间的结果进行了比较和对比。后一时期记录的胸部病变患病率比前一时期低33%。跗关节病变的患病率在两个时期相似，但1986/87年单个鸡群记录的病变患病率的变化程度大幅降低。饲养密度、平均出栏年龄和鸡的性别在两个时期都对肉鸡群中该病的患病率有影响。该病在冬季鸡群中更常被记录到，并且与环境相对湿度有很强的相关性。
