실험 디자인

  • 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. typhimurium 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
