초록

본 연구는 항생제 사용 유무가 계육 품질 등급에 미치는 영향을 조사하기 위하여 전체 340육계농가(항생제사용 농가 305개소와 무항생제 농가35개소)를 대상으로 전체 10,420,792수 중 1농가 당 100수씩을 무작위로 선별하여 총 34,000수에 대한 등급 판정 결과를 활용하였다. 연구 결과 항생제 사용 유무에 따른 육계의 일당 증체량은 차이를 보이지 않았으나, 품질 A 등급 출현율은 항생제 사용 농가에서 출하된 계육(78.87%)이 무항생제 농가(73.46%)에 비해 높게 나타남이 확인되었다(P<0.05). 이러한 결과를 보인 이유는 품질 A 등급을 받기 위해 판정되는 경제적 및 비경제적 도체 결함의 발생 빈도가 무항생제 농가에서 출하된 계육이 항생제 사용농가에 비해 높게 나타났기 때문이며, 특히 도체 결함과 품질 A 등급과의 상관관계 분석에서 가장 높은 부(-)의 상관관계를 보인 외관 결함의 발생이 무항생제 농가에서 출하된 계육에서 항생제 사용 농가에 비하여 약 1.8배 높음이 확인 되었다. 본 연구결과 무항생제 농가는 항생제 사용 농가에 비해 높은 품질 등급의 계육 생산이 더 어려운 것으로 사료되며, 무항생제 계육 생산의 확대를 위해서는 국가적 차원에서 사양기술 수준의 향상, 천연 항생제 대체 물질의 개발과 함께 가격 차등에 따른 적절한 경제적 보상도 함께 이루어져야 할 것으로 판단된다.

The objective of this study was to investigate the effect of the supplementation of antibiotics on meat quality grade of broiler carcasses under the Korean meat grading system. A total of 34,000 broiler carcasses, which were randomly selected 100 broilers from each farm in 340 broiler farms (305 farms with antibiotics; 35 farms without antibiotics), were used in this study. Average daily weight gain of broilers was not significantly affected by the use of antibiotics. The ratio of quality grade A was higher in the broiler carcasses from the farms with antibiotics supplementation (78.87%) than those without antibiotics (73.46%, P<0.05). The numbers of carcass defects, which are down-grade factors of meat grading system, were much higher in the broiler carcasses produced from the farms without antibiotics supplementation when compared with those with antibiotics. In particular, the incidence of the carcass defect on conformation was approximately 1.8 times higher in the carcasses from the farms without antibiotics supplementation than those with antibiotics, which showed the highest negative correlation with quality grade A. Therefore, the improvement of farm management system, the use of antibiotics alternatives from natural products, and a proper incentive should be considered in various ways to encourage farmers to reduce antibiotics usage in their farm and earn consumers' trust for antibiotics-free products.
