사육면적에 따른 비육돈의 생산성 및 공격행동의 변화

국문 초록 (Abstract)

본 연구는 돈사 내 사육밀도에 따른 비육돈의 생산성 및 공격 행동 특성을 파악하기 위해 수행되었다. 돈사별 사육 밀도는 저밀도(0.6㎡), 중밀도(0.8㎡), 고밀도(1.0㎡)로 구분하여 돈방별로 8두씩 총 24두 (평균체중 : 75.1±4.3kg)를 공시하여 총 56일간 사양시험 및 공격행동 분석을 실시하였다. 사양시험기간 동안 사료와 물은 자유섭취하게 하였다. 시험종료시 체중과 증체량 및 일당증체량은 저, 중밀도 사육이 고밀도 사육과 비교하여 유의적으로(p <.01) 증가하였으며, 도체중은 저밀도 및 중밀도 사육시 유의적으로 (p <.01) 증가하였으며, 등지방두께는 저밀도 사육 시 유의적으로 (p <.01) 증가하였다. 공격행동 분석의 결과는 유의적인 차이는 나타나지 않았지만, 공격행동 빈도가 저밀도 군에서 평균 32.0회로 가장 낮은 빈도로 발생하였다. 또한 귀물기, 몸통물기, 싸움행동은 사육밀도에 따른 유의적인 차이는 나타나지 않았으나, 귀물기 행동에서는 중밀도 처리구에서 저밀도 및 고밀도 처리구와 비교하여 유의적으로 (p<.05) 증가하였다. 본 연구 결과 비육돈의 사육밀도는 생산성 및 공격행동에 영향을 미치는 것을 확인하였다.

This study examined the growth performance and aggressive behavioral characteristics of growing pigs of different stock densities. Totally, 24 growing pigs (average weight: 75.1±4.3kg) were randomly assigned to one of the 3 stock densities, each pen containing 8 pigs: low density (0.6㎡/pig), medium density (0.8㎡/pig), and high density (1.0㎡/pig). All animals were fed ad libitum diet for 56 days. Our results indicate that the final body weight, body weight gain, average daily gain, and dressed weight, are greater for low and medium density stocks (p <0.01), as compared to the high density stock. Backfat thickness was greater for low density than other densities (p <0.01). Behavior analysis revealed lowest frequency of aggression in the low density group, with an average of 32.0. No significant differences were obtained for ear biting, body biting, and fighting, among the stock densities. However, ear biting was greater in the medium density stock than in the other densities (p <0.05). Results of this study confirm that the stock density of finisher pigs exerts considerable effect on the weight gain and aggressive behavior of the animals.
