초록
Pneumonia is one of the important diseases in commercial pig. In order to delineate the relationships with pneumonia and productions traits, five different economic traits including carcass weight(CW), backfat thickness(BF), meat quality(MQ), carcass characteristics(CC) and pork belly thickness(PB) were measured in 6,362 commercial pigs. Significant differences were observed in all the traits with pneumonia(P<0.01). Carcass weight and backfat thickness decreased significantly as the symptom of pneumonia was severed (P<0.01). Also, when the pneumonia was severed, the carcass characteristics and meat quality became worse compared with normal unaffected animals(P<0.01). In case of pork belly thickness, the significant decrease was observed in pneumonia infected animals compared with normal animals(P<0.01). Based on this study, the pneumonia infection affects most of the important economic traits in pigs and it is ultimately needed to pay more attention to prevent this disease.

Also, when the pneumonia was severed, the carcass characteristics and meat quality became worse compared with normal unaffected animals(P<0.01). In case of pork belly thickness, the significant decrease was observed in pneumonia infected animals compared with normal animals(P<0.01). Based on this study, the pneumonia infection affects most of the important economic traits in pigs and it is ultimately needed to pay more attention to prevent this disease.
