실험디자인


• 공시동물 : 14두 이유자돈 (28일령)
• 실험처리 : (1) S.typhimurium 공격접종 + 일반사료 
                (2) S.typhimurium 공격접종 + 사료내 0.1% 박테리오파지 첨가
• 박테리오파지 첨가제의 표적 병원성 미생물 : S.typhimurium
• 실험기간 :14일

 

 

주요 결과 및 결론

 

• 사료내 0.1% 박테리오파지의 첨가는 S. typhimurium에 감염된 이유자돈의 일당증체량 (57%) 및 사료효율(55%)을 향상시킴(P < 0.05; Figure 9)
• 사료내 0.1% 박테리오파지의 첨가는 S.typhimurium에 감염된 이유자돈의 분변내 S.ty￾phimurium 검출량(3일: 75%, 7일: 70%)을 감소시킴(P < 0.05; Figure 10)
• 하지만, 기타 소화기관내 S.typhimurium 검출량은 유의적인 효과가 나타나지 않음


 S.typhimurium에 감염된 이유자돈에게 사료내 0.1% 박테리오파지의 첨가
- 이유자돈의 생산성 개선 및 분변내 S.typhimurium 검출량 감소
