An experiment was conducted with 240 broiler chickens (ROSS 308) to evaluate the influence of supplementation of a probiotic feed mixture (PFM) including Bacillus subtillus, Streptomyces galilaeus, and Sphingobacteriaceae on growth performance and quality of chicken meats. Broiler chickens were rand...

생균제의 특징은 무엇인가? | 사료용 생균제는 숙주동물에게 유익한 영향을 주어장내 미생물 환경을 개선하고[4] 유해세균의 성장을 억제함과 동시에 영양소의 소화 흡수를 도와주어 가축의 생산성을 향상시키는 것으로 알려졌다[5-7]. 생균제는 박테리오신을 분비하여 유해 세균의 증식을 억압하고[8], 암모니아, 황화수소, 각종 아민류, 인돌, 페놀류 등의 독성물질의 생성을 억제한다[9]. 생균제는 세균의 세포벽을 구성하는 물질인 펩티도글리칸을 파괴하고 소화기관의 상피세포에 유해세균의 부착, 증식을 차단한다[10, 11]. | |
전 세계적으로 사료용 항생제 사용이 규제된 이유는 무엇인가? | 가축의 질병 예방과 성장촉진을 위해 사용되어온 사료용 항생제로부터 기안한 슈퍼박테리아 문제가 심각한 사회적 현안으로 대두되면서 브로일러의 생산성과 닭고기 품질개선에 대해 관심이 많아졌다[1,2]. 전 세계적으로 사료용 항생제 사용이 규제됨으로써 사료용 생균제는 가축의 면역력 개선, 성장능력 및 축산물의 품질 향상을 위한 항생제 대체재로서 널리 이용되고 있다[3]. | |
브로일러에서 사료용 생균제는 어떤 역할을 하는가? | 브로일러에서 사료용 생균제는 소화기관의 영양대사 능력 개선을 통한 성장촉진제로써 널리 사용되며[12], 면역 시스템을 자극하여 항산화 능력을 향상 시키고 닭고기의 생산성과 품질을 향상시킨다[13, 14]. 최근, 브로일러에서 사료용 복합 생균제가 단일 생균제와 비교할 때 항산화, 면역반응, 성장능력, 닭고기의 생산성 및 품질 개선효과가 더욱 우수하다는 보고가 있다[15]. |
