Abstract

This study was undertaken to evaluate and compare the status of animal welfare, environmental level, and sow behavior, by including two farmhouses with sow group housing but having different floor types, viz., litter floor and slat floor. Animal welfare level was evaluated for body and vulval wounds of sows. The environmental level was measured for a total of 4 months, assessing the concentrations of H2S, NH3 and CO2 inside the pig house, once a month. Results of this study indicate that the level of animal welfare, with respect to body and vulval wounds, was better in the concrete slat floor farmhouse (H) than in the litter floor farmhouse (K). Environmental levels obtained (in ppm) were: H2S (H, 1.0; K, 0.0), NH3 (H, 45.4; K, 1.3), and CO2 (H, 1102.3; K, 258.8), indicating higher levels in the H than in K farmhouse. Aggressive behavior was mainly encountered in the H farmhouse. These results indicate that the same group housing system, but with different flooring, results in changes pertaining to aggressive behavior and environmental levels. It is therefore necessary to study the behavior changes, welfare, and environmental levels while deliberating different floor types.

최근 우리나라는 축산농가의 사육환경 개선을 위해 양돈 농가를 대상으로 새로운 동물복지형 사육기준을 도입하려고 한다. 이에 모돈의 군사사육 도입 규정에 대응할 수 있는 모돈사 바닥에 대한 연구들이 필요한 실정이다. 본 연구의 목적은 모돈의 군사사육 방식이면서 바닥의 형태가 각각 깔짚과 슬랏 바닥의 형태로 되어 있는 농가 2곳을 섭외하여 동물복지 수준과 환경 수준 및 모돈의 행동을 평가 및 비교하였다. 동물복지 수준평가는 실험농가 모돈의 몸상처와 외음부상처 평가, 환경 수준은 돈사 안의 황화수소, 암모니아, 이산화탄소 농도를 한 달에 1번씩, 총 4 개월간 측정하였다. 연구 결과 동물복지 수준은 모돈의 몸과 외음부 상처비율이 깔짚 바닥 농가(K 농가)에 비해 콘크리트 슬랏 바닥 농가(H 농가)에서 높게 관찰 되었다. 모돈의 돈방 내의 환경수준은 각각 황화수소 (H2S; H 농가 1.0 ppm, K 농가 0.0 ppm), 암모니아 (NH3; H 농가 45.4 ppm, K 농가 1.3 ppm), 및 이산화탄소 (CO2; H 농가 1102.3 ppm, K 농가 258.8 ppm) 농도가 H 농가에서 높게 측정 되었다. 모돈의 행동분석 중 투쟁행동은 H 농가에서 주로 발생 하였다. 이와 같은 결과는, 동일한 군사형태의 사육시설이지만 바닥재의 차이로 인해 공격행동과 환경수준의 변화를 나타나는데, 향후 추가적으로 바닥재의 종류 및 바닥의 변화들을 제시하면서 행동변화, 동물복지 및 환경수준을 측정하는 연구가 필요 할 것으로 판단된다.
