Antimicrobial agents were added to the feed of swine for three weeks to determine the interrelationships of potentially pathogenic agents in the nasal tract, turbinate atrophy and weight gains. Bordetella bronchiseptica was not isolated from the groups fed the combination of chlortetracycline, penicillin and sulfamethazine. B. bronchiseptica was found in some pigs after the feeding trail, but this organism was not significantly associated with turbinate atrophy at the time of slaughter.Mycoplasma hyorhinis was not found in the nasal passages of the pigs that received feed containing high concentration chlortetracycline but was found in pigs that received other diets. Hemophilus suis was not significantly reduced by any of the treatments used. The organisms studied in the pigs were not isolated from the personnel handling the pigs.
在猪的饲料中添加抗菌剂三周，以确定鼻腔中潜在病原体、鼻甲萎缩和体重增加之间的相互关系。在喂食金霉素、青霉素和磺胺二甲嘧啶组合的猪群中未分离出支气管败血波氏杆菌。在饲养试验后，在一些猪中发现了支气管败血波氏杆菌，但在屠宰时，这种微生物与鼻甲萎缩没有显著关联。在接受高浓度金霉素饲料的猪的鼻腔中未发现猪鼻支原体，但在接受其他日粮的猪中发现了该病原体。所使用的任何一种处理方法都没有使猪链球菌显著减少。在猪身上研究的病原体未从接触猪的人员中分离出来。
