매년 찾아오는 가축 질병과 강화되는 정부 규제 등 생산기반이 위축되는 상황에서 현 오리사육 농가가 생산성을 높여야 할 필요가 있다고 느낀 청정오리농장 황문주 대표는 고상식 오리사를 도입했다. 고상식 오리사는 깔짚을 사용하지 않아 작업자가 오리사에 들어갈 필요가 없어 작업자로 인한 가축질병 감염 위험이 특히 적다. 또 단위면적당 사육수수 증가로 더 많아 소득에도 도움이 될 것으로 기대된다. 특히 최근 정부에서 가설건축물에 대한 축산업 허가를 불허하고 기존 가설건축물도 5년 이내 건축허가를 받아야만 한다. 청정오리농장은 기존 비닐하우스 축사를 보강해 무창 오리사로 리모델링을 통해 정식 건축허가를 받았다는 점도 주목할만하다. 기존 축사를 리모델링할 경우 신축 대비 비용도 1/3로 절감 가능하다는게 황 대표의 설명이며 축사에 대한 투자 여력이 부족한 오리농가들에게 대안으로 주목받고 있다. 이 뿐만 아니라 황문주 대표는 최근 새로운 도전에 나서고 있다. 축사 1동을 고상식 축사로 개조해 사육실험을 하고 있는 것이다. 고상식 축사는 깔짚이 필요없을 뿐만 아니라 환경개선으로 질병차단은 물론 생산성 향상에도 크게 도움이 되고 있다는 것이 황 대표의 설명이다.

This experiment was conducted to investigate the effects of floor type and heating system on performance, housing environment and health status of ducks reared in three types of duck house (OD : Open floor house-Direct heating system, OF : Open floor house-Floor heating system and LD : Loft type house-Direct heating system). In OF treatment, PVC pipes were installed for heating under concrete floor and covered with litter. In LD treatment, plastic mesh was installed 50 cm above the floor so that duck's droppings can pass through it. Each treatment had four replicates of 25 birds (Cherry Valley duck breed) per pen. There were no significant differences in weight gain and feed intake of ducks for 6 weeks among all treatments. However, feed conversion ratio in LD was significantly higher (p<0.05) than that in OF. No differences were found in carcass charac- teristics, with the exception of abdominal fat weight where OF were higher than the others. Concentrations of $CO_2$ and $NH_3$ gas in OD were higher than those of OF and LD at 3, 4 and 5 weeks. Moisture content in litter of OF was lower than that of OD. In contrast, the amount of dust in the air was higher in OF than in OD. The amount of fuel used for 6 weeks in LD was lower about 21% than that in OD. Some of unusual symptoms were observed in open floor house and loft type house, such as lying, spraddle legged, twisted ankle and legs, wounded sole, or etc. No components of leukocyte and erythrocyte of blood were significantly different among all treatments. The results of this experiment showed that OF and LD systems had no positive effects on performance of meat type commercial duck. However, there were some positive effects of certain house type for the improvement of environmental condition in duck house for hygienic production. In the future, more research on the effect of various facilities and systems for duck house is needed.

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.
