- W2024220061 abstract "본 시험은 토종오리와 육용오리를 교배 조합하여 토종오리의 생산성과 도체 수율을 개선시키기 위해 수행되었다. 공시 동물은 청둥오리와 육용오리의 교배 조합으로 발생한 4계통의 오리들을 암수 각각 120수씩 선별하여 총 240수를 이용하였다. 교배 방법은 토종오리(female)<TEX>${times}$</TEX>토종오리(male), 육용오리(female)<TEX>${times}$</TEX>토종오리(male), 토종오리(female)<TEX>${times}$</TEX>육용오리(male), 육용오리(female)<TEX>${times}$</TEX> 육용오리(male)4계통을 각각 A, B, C, D로 하고, 암수를 분리하여 계통과 성별에 따라 각각 30수씩 선별하였다. 시험 사료는 육용오리 사료를 0~3주령(CP 22.0%, ME 2,900 kcal/kg)과 3~8주령(CP 18.0%, ME 3,000 kcal/kg)으로 나누어 8주 동안 급여하였다. 체중은 8주령에 암컷에 비해 수컷이 높게 나타났으며(P<0.05), 3주령과 8주령 모두 B, C계통 체중이 A계통 보다 높고 D계통보다는 낮게 나타났다(P<0.05). 증체량은 3~8주령과 0~8주령 동안에는 암컷에 비해 수컷에서 높았으며(P<0.05), 3~8주령 동안의 계통 간 증체량은 D>C>B>A순서로 높았다(P<0.05). 사료 섭취량의 경우, 증체량과 마찬가지로 암수간의 비교에서 차이가 없었으나, A계통에 비해 B계통과 C계통이 높았고, D계통이 다른 계통들에 비해 가장 높았다(P<0.05). 사료 요구율은 3~8주령에 수컷이 높았으며(P<0.05). 계통간 사료 요구율은 3~8주령과 0~8주령에는 A계통과 B, C계통, B계통과 D계통 사이에 유의적인 차이가 있었다(P<0.05). 4계통의 생체중과 도체중에 따른 도체 수율은 4계통이 각각 70.1%, 70.8%, 73.1% 및 71.2%로 나타났다. 따라서, 토종오리와 육용오리의 교배 조합은 토종오리의 생산성을 개선시킬 수 있을 것으로 사료된다. This work was carried out to improve the performance and the carcass yield of Korea native duck (KND) according to crossbreeding KND and broiler duck (BD). Two hundred forty out of crossbred ducks were divided into 4 strains and selected as 120 ducks separated by sex, respectively. Crossbred ducks were native ducks (female)<TEX>${times}$</TEX>native ducks (male), native ducks (female)<TEX>${times}$</TEX>broiler ducks (male), broiler ducks (female)<TEX>${times}$</TEX>native ducks (male), and broiler ducks (female)<TEX>${times}$</TEX>broiler ducks(male) as A, B, C and D, respectively. Broiler duck diet was fed as experimental diet for 0~3 weeks (CP 22.0%, ME 2,900 kcal/kg) and 3~8 weeks (CP 18.0%, ME 3,000 kcal/kg). Body weight of male was high compared to female, and that of B and C was high compared to A and low compared to D at 3 and 8 week (P<0.05). Body weight gain of male was high compared to female at 3~8 weeks and 0~8 weeks, and it was shown as D>C>B>A on body weight gain (P<0.05). In case of feed intake, there was no difference between male and female, and B and C were high compared to A and low compared to D (P<0.05). Male feed requirement was high at 3~8 weeks, and there was significant difference between A and B, C and between B and D. Carcass yield of 4 strains was shown as 70.1%, 70.8%, 73.1% and 71.2%, respectively. Finally, Crossbreeding of KND and BD may improve the performance and the carcass yield of KND." @default.
