유도 환우의 특징은? | 유도 환우는 육성 경비의 절감, 산란율, 하우 유니트, 난각질 등의 개선 및 정상란 비율의 향상 등 여러 가지 이점이 기대될 수 있으나, 절식에 따른 과중한 스트레스에 의한 폐사의 증가, 환우 중 분변 성상의 악화에 따르는 작업성의 악화, 환우 후난중의 과대화 등의 문제점도 가지고 있다(Baker et al., 1983). | |
환우 유도의 가장 실용화된 방법은 무엇인가? | 환우 유도의 가장 실용화된 방법은 10~14일 동안 절식시키는 것으로, 절식에 의한 유도 환우는 관리가 쉽고, 환우를 효율적으로 유도하며, 환우 후 산란계의 생산 수명을 연장시키는 경제적 이점을 가지고 있다(Brake, 1993). 그러나 절식에 의한 유도 환우는 산란계에서 스트레스를 증가시키는 원인이 되며, 살모넬라 감염에 대한 감수성을 증가시키는 등 부정적 측면들도 보고되고 있다(Holt와 Porter, 1992; Holt, 1993; Holt et al. | |
절삭에 의한 환우 유도의 문제점은? | 환우 유도의 가장 실용화된 방법은 10~14일 동안 절식시키는 것으로, 절식에 의한 유도 환우는 관리가 쉽고, 환우를 효율적으로 유도하며, 환우 후 산란계의 생산 수명을 연장시키는 경제적 이점을 가지고 있다(Brake, 1993). 그러나 절식에 의한 유도 환우는 산란계에서 스트레스를 증가시키는 원인이 되며, 살모넬라 감염에 대한 감수성을 증가시키는 등 부정적 측면들도 보고되고 있다(Holt와 Porter, 1992; Holt, 1993; Holt et al., 1995). |
