在对肺炎猪生长性能差的调查中，研究了肺炎猪的增重率和饲料效率。在研究期间，猪要么被安置在改善的环境中，要么留在自己的农场。在这两种环境中，增益率往往与肺炎严重程度的增加相关。当对肺部病变程度相似的猪进行比较时，在改善环境中饲养的猪的生长性能优于家庭农场中的猪。然而，在两种环境中，肺炎影响超过20%肺组织的猪的生长性能同样差。当住房类型和肺炎程度纳入方差分析模型中时，住房对增重率有非常显著（P = 0.003）的影响，而肺炎无显著影响。
During an investigation of poor growth performance, rate of weight gain and feed efficiency were studied in pigs with pneumonia. During the study, pigs either were housed in an improved environment or remained at their home farm. In both environments, rate of gain tended to decrease in association with increasing severity of pneumonia. When pigs with similar extent of lung lesions were compared, growth performance of pigs housed in the improved environment was better than that of pigs on the home farm. However, growth performance of pigs with pneumonia affecting greater than 20% of lung tissue was equally poor in either environment. When type of housing and extent of pneumonia were included in a model for analysis of variance, housing had a highly significant (P = 0.003) effect on rate of gain, and pneumonia had a nonsignificant effect.
