초록

본 연구는 다양한 사육밀도가 국내 토종오리의 성장 생산성에 미치는 영향을 연구하기 위하여 수행되었다. 공시동물은 국내 토종오리 농가에서 발생된 1일령 토종 실용오리 1,200수를 암수 구분 없이 56일 동안 오리사(무창, 고상식)에서 사육하였으며, 2주령 토종오리(350±30 g) 852수를 처리구당 균일도가 80% 이상이 되도록 선별하여 14~50일 동안 사육밀도 시험을 실시하였다. 시험사료는 옥수수-대두박 위주의 육용오리 사료를 0~21일령 (CP 21%, ME 2,900 kcal/kg), 21~50일령(CP 17%, ME 3,100 kcal/kg)으로 나누어 이용하였다. 처리구는 4~9 수/㎡의 사육밀도에 따라 총 6처리구, 처리구당 4반복으로 하였다. 체중은 처리구 사이에서 유의차가 없었으나, 균일도는 사육밀도가 높을수록 낮아졌다(P<0.05), 42~50일령의 사료섭취량과 사료요구율은 T1~3 처리구에 비해 T4~6 처리구에서 감소하였다(P<0.05). 전체 시험 기간을 보았을 때, 증체량은 처리구 사이에서 유의적인 차이를 보이지 않았으나, 사료섭취량은 사육밀도가 높아질수록 유의적으로 감소하였으며(P<0.05), 사료요구율은 6처리구에서 각각 처리구에 따른 유의차를 보였다(P<0.05). 결론적으로, 고상식 토종오리의 사육밀도는 생산성과 균일도를 고려하여 7 수/㎡가 적정 수준이라고 사료된다.

This study investigated the effects of various stocking densities on the growth performance of Korean native ducks. Twelve hundred day-old ducklings were reared for 50 days in a duck house (windowless, plastic wire-floor pen). Two weeks later, 852 of these ducks (350±30 g) were selected for at least 80% uniformity per stocking treatment (six treatments, four replications/treatment, depending on a stocking density of 4~9 birds m-2). Experimental diets were corn-soybean-based and broiler ducks were grouped based on age [0~21 days of age (CP 21%, ME 2,900 kcal/kg) and 21~50 days of age (CP 17%, ME 3,100 kcal/kg)]. Body weight (BW) did not significantly differ among different aged treatment groups (P>0.05); however, uniformity decreased with higher stocking densities (P<0.05). Feed intake and feed conversion ratio of ducks aged 42~50 days significantly decreased in the T4-6 treatments compared with the T1-3 treatments (P<0.05). In all experimental periods, BW gain was not significantly different among treatments, but feed intake decreased significantly as the stocking density increased (P<0.05), and feed conversion ratio was significantly different among six treatments with stocking density (P<0.05). In conclusion, we found that the stocking density of Korean native ducks in a plastic wire-floor pen was approximately 7 birds m-2 in consideration of productivity and uniformity.
