Abstract

The present experiment was carried out to compare performance, carcass characteristics and meat quality among three major meat-type duck strains in Korea. Two commercial duck (CD) strains, produced from parent stocks (PS) (Cherry Valley and Grimaud), and $F_1$ strains, self-produced by farmers, were used in an 8-week feeding experiment. Both feed conversion ratio and production index were significantly higher in Cherry Valley strain compared with the other two at the ends of 6 and 8 weeks (p<0.05). However, no differences were found in carcass characteristics and meat quality, with the exception of abdominal fat weight where Grimaud were higher than the others. Overall, the results of the current study show that Cherry Valley CD strain had higher performance among three strains tested.

본 연구의 목적은 수입종오리(PS)에서 생산된 육용오리와 농가에서 자가 생산된 육용오리 계통($F_1$)의 생산성과 오리의 도체 성상 및 육질 특성을 비교 연구하는 것이다. 생산성에 있어서 체리밸리, 그리모, $F_1$이 각각 6주령 체중은 3,294 g, 3,248 g, 3,217 g였고, 8주령에는 4,013 g, 3,852 g, 3,922 g으로 체리밸리가 가장 높은 체중을 보였다. 또한 각 계통의 체중 성장의 변화를 볼 때, 그리모는 초기 성장은 빠르나 후기 비육이 떨어지는 경향을 보이며, 이에 반하여 체리밸리와 $F_1$은 나란한 성장을 보이고 있다. 사료 섭취량은 전 기간에 걸쳐 $F_1$ 9,935 g, 그리모 9,872 g, 체리밸리 9,584 g 순으로 높은 경향을 보였다. 사료 요구율은 체리밸리가 6주령에 1.93, 8주령에 2.42로 타 계통에 비해 전반적으로 좋은 성적을 보였다. 생산지수 값에서도 체리밸리가 6주령과 8주령에 각각 405.6, 295.9로 그리모, $F_1$보다 유의적으로 높았다(p<0.05). 도체율은 각 처리간에 유의차는 없었으나 6주령과 8주령의 복강지방 함량은 그리모가 유의적으로 높았다(p<0.05). 부분육의 도체 수율은 전 부위에서 유의차가 없었고, 주령이 증가할수록 다리의 비율은 줄어들고 가슴의 비율은 늘어나는 경향을 보였다. 시험에 사용된 세 계통 간 가슴육의 물리 화학적 특성에서는 각 처리 간에 유의적인 차이는 없었다. 모두 페킨종에서 개량된 계통이지만 육질에 관한 개량은 아직 미진한 것으로 사료된다. 전체적으로, 본 연구의 결과는 국내 환경에서 생산 성적은 체리밸리 계통이 타 계통에 비하여 좋은 경향을 보였으나, 육질에서는 계통 간에 유의적 차이는 없었다.
