The occurrence and incidence of pneumonia in housed calves were not related to the selenium status of the herd as measured by blood glutathione peroxidase activity nor were they affected by selenium treatment of calves during the neonatal period. Pneumonia was related more closely to herd size and building design.
圈养犊牛肺炎的发生情况和发病率与通过血液谷胱甘肽过氧化物酶活性测定的牛群硒状况无关，在新生期对犊牛进行硒处理也不会对其产生影响。肺炎与牛群规模和牛舍设计的关系更为密切。
