Abstract

Various factors negatively affect poultry production, including a multitude of avian pathogens. Among them, Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) cause world-wide economic losses in the poultry industry. Although respectively, MG and MS induce chronic respiratory disease and synovitis in poultry, these pathogens often manifest as clinically inapparent infections and many countries are therefore having difficulties effectively eradicating them. In this study, five broiler breeder farms in Korea were investigated for the presence of Mycoplasma infection from 2016 to 2018. Serum samples were collected for detection of antibodies to mycoplasma species using an enzyme-linked immunosorbent assay (ELISA) kit. Additionally, the production index and feed conversion rate of broilers were recorded. According to this investigation, broiler breeder farms in 2018 were serologically negative for Mycoplasma infection with broilers exhibiting a high production index and low feed conversion rate. Thus, eradicating mycoplasma in poultry farms is critical for improving chick quality and overall poultry production.

닭 마이코플라즈마병은 전세계적으로 양계산업에 문제시 되고 있는 난계대 질병으로 병아리 품질 및 사육성적에 영향을 미친다고 알려져 있다. 본 연구는 닭 마이코플라즈마병에 대한 백신 접종을 실시하지 않은 계열화 회사의 육용 종계군을 대상으로 정기 채혈을 통해 혈청검사를 실시한 후 감염율을 확인하였고, 조사계군에서 생산된 육계 병아리에 대한 사육성적을 확인하고자 하였다. 육용종계 닭 마이코플라즈마 감염율과 그에 따른 후대병아리의 사육성적을 연도별로 확인한 결과, 종계군의 감염율이 낮아짐에 육계의 사육성적이 높아진다는 상관관계를 확인하였다. 이러한 결과를 토대로 비추어 보았을 때, 닭 마이코플라즈마병의 감염 유무는 생산된 초생추의 품질과 사육농장 성적 영향에 미치는 여러 요소들 중 하나라고 판단할 수 있다.
