Abstract

This study was carried out to investigate the growth performance and the carcass ratio of meat-type Korean Native Ducks. Four hundred twenty Korean Native Ducks' chicks were selected and divided into four treatments (7 replications/ treatment, 15 birds/replication) by strains (A and B) and gender(male and female) with $2{\times}2$ fractal factors. There was no significant difference between A and B on the body weight at 2, 4, 6, and 8 weeks old (P>0.05). However, body weight of female was higher at 2 weeks old than male while that of male was higher at the 8 weeks old (P<0.01). Daily feed intake of male was higher compared to female during 6~8 weeks (P<0.05). On weekly body weight gain, there was no significant difference between strains, but gained body weight of male was higher until 2 weeks old while that of female was higher during 6~8 weeks (P<0.01). On the live body weight and carcass weight by strains and genders, B strain was higher than A strains at the 8 weeks of age (P<0.01). Carcass yield was the highest at 8 weeks of age in both strains (P<0.05). These results may provided the basic data on growth performance and carcass ratio of meat-type Korean Native Ducks.

본 시험은 토종오리 육용종의 생산성과 도체수율을 조사하기 위해 수행하였다. 공시동물은 A와 B계통 육용종 토종오리에서 발생한 오리 병아리를 암수 각각 210수씩 선별하여 총 420수를 이용하였다. 시험 설계는 농장에 따른 2처리구(A, B)와 성별에 따른 2처리구(암, 수)로 나누어 $2{\times}2$의 복합요인으로 총 4처리구, 처리구당 7반복, 반복당 15수씩 완전임의 배치하였다. 주령별 체중은 계통 간 비교에서 2, 4, 6 및 8주령에 체중의 차이가 없었으나(P>0.05), 성별에 따라서는 2주령에 암컷, 8주령에 수컷의 체중이 높았다(P<0.01). 주령별 일일 사료 섭취량은 암수 비교에서 6~8주령에 수컷의 섭취량이 높았다(P<0.05). 주령별 증체량은 계통 간에 유의적인 차이가 없었으나, 암수 비교에서는 수컷이 높았다(P<0.01). 주령별 사료 섭취량은 계통에 따른 차이는 없었으며(P>0.05), 암수 비교에서는 6~8주령에 수컷의 사료 섭취량이 암컷에 비해 높았다(P<0.05). 주령별 사료 요구율은 계통 간 비교에서 차이가 없었으며, 암수 비교에서 0~2주령에암컷(P<0.05), 6~8주령에수컷이 높았다(P<0.01). 계통과 주령에 따른 생체중과 도체중은 8주령 B계통에서 가장 높았으며(P<0.01), 도체율은 8주령의 A와 B계통이 가장 높게 나타났다(P<0.05). 이런 결과들은 토종오리 육용종의 생산 성적과 도체수율에 대한 기초적인 자료로서 이용될 것이라 사료된다.
