Abstract

This study was undertaken to assess dietary crude protein (CP) and amino acid (AA) concentrations for growth performance and carcass characteristics in Korean native ducks. In a $2{\times}3$ factorial arrangement, 1-d-old Korean native male ducks were allotted to 6 dietary treatments in a completely randomized design. Experimental diets contained 23 or 21% CP with 1.31/1.09, 1.21/1.00, 1.11/0.91 and 1.11/0.91, 1.02/0.83, 0.92/0.75 AA (Lysine/Total sulfur amino acid, Lysine/TSAA), respectively, from 0 to 3 wk of age. From 4 to 8 wk of age, experimental diets had 19 or 17% of diet; each contained 1.00/0.79, 0.94/0.75, 0.88/0.71 and 0.88/0.71, 0.82/0.67, 0.76/0.63 AA (Lysine/TSAA), respectively. Each dietary treatment has 6 replicates and feed and water were provided ad libitum. Body weight (BW), feed intake and uniformity were measured at 3 wk and 8 wk and carcass characteristics were evaluated at 8 wk of age. As CP increased from 21 to 23%, the BW and BW gain significantly increased (P<0.05) during 0 to 3 wk of age. From 4 to 8 wk of age, BW, feed intake, BW gain, feed conversion rations (FCR) and uniformity were not different (P>0.05) between treatments. Carcass yield and relative weights of liver, spleen, right breast and leg per 100 of BW were not different (P>0.05) between treatments. The meat color, shear force value, cooking loss and pH were not affected by dietary treatments (P<0.05). Korean native ducks require relatively low levels of dietary CP and AA for late growth and carcass yield due to low daily weight gain. This suggests the possible differences in CP and AA needs between Korean native ducks and commercial breeds from foreign breeding companies, especially late growth stage.

본 실험은 조단백질과 아미노산(Lysine/TSAA) 수준이 토종오리의 생산성 및 도체 특성에 미치는 영향을 연구하기 위해 수행되었다. 육성 전기는 토종오리 450수를 6개 처리에 공시하여 사용하였으며, 육성 후기는 육성 전기를 거친 토종오리 중 360수를 6개 처리에 공시하여 사용하였다. 육성 전기의 실험 사료는 조단백질 23 및 20% 아미노산(Lysine/TSAA)은 각각 1.31/1.09, 1.21/1.00 및 1.11/0.91와 1.11/0.91, 1.02/0.83 및 0.92/0.75였으며, 육성 후기에는 조단백질 19 및 17%, 아미노산(Lysine/TSAA)은 각각 1.00/0.79, 0.94/0.75 및 0.88/0.71와 0.88/0.71, 0.82/0.67 및 0.76/0.63로 처리하여 사용하였다. 육성 전기 실험 결과는 조단백질 수준이 증가함에 따라 생체중과 일당 증체량이 유의적으로 개선되었지만(P<0.05), 아미노산(Lysine/TSAA)과 조단백질 ${\times}$ 아미노산(Lysine/TSAA) interaction에 유의차는 나타나지 않았으며, 균일도는 조단백질, 아미노산(Lysine/TSAA) 및 조단백질 ${\times}$ 아미노산(Lysine/TSAA) interaction 모두에서 유의차가 나타나지 않았다. 육성 후기 실험 결과는 성장성적, 도체율 및 상대적 중량 모두에서 조단백질, 아미노산(Lysine/TSAA) 및 조단백질 ${\times}$ 아미노산(Lysine/TSAA) interaction간 유의차가 나타나지 않았으며, 토종오리 고기의 화학 및 물리적 특성인 육색, pH, 전단력가 및 가열 감량에서도 조단백질, 아미노산(Lysine/TSAA) 및 조단백질 ${\times}$ 아미노산(Lysine/TSAA interaction)간 유의차가 나타나지 않았다. 본 실험 결과, 토종오리는 육용종 오리와 달리 육성 후기의 경우 낮은 성장률으로 인하여 상대적으로 낮은 조단백질과 아미노산 수준이 필요할 것으로 사료된다.
