This study was conducted to investigate the effects of dietary quercetin on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chickens. Three hundred twenty one-day old Ross broilers were divided 8 treatments (C(-), basal diet; C(+), basal di...

면역기능 활성화 물질에는 무엇이 있는가? | 최근, 항생제 대체 물질로서 가축의 체내 면역기능을 활성화시키는 물질에 대한 연구가 활발히 진행되고 있다. 이런 면역기능 활성화 물질에는 생균제(probiotics), 산미제(acidifiers), 효소제(enzymes), 광물질 첨가제(mineral supplements) 그리고 올리고당(oligosaccharide) 등이 있다. 또한 동물(Zasloff, 1987; Skerlavaj et al. | |
가축의 생산성 극대화, 고밀도 사육 및 열악한 사육 환경으로 인한 질병 발생 예방을 목적으로 사료 내 성장촉진용 항생제를 이용하면 나타나는 문제점은? | 가축의 생산성 극대화, 고밀도 사육 및 열악한 사육 환경으로 인한 질병 발생 예방을 목적으로 사료 내 성장촉진용 항생제를 이용하여 왔다. 그러나 축산물 내 항생제 잔류 및 내성균 출현 등의 문제가 대두되면서 수입 축산물에 대한 경쟁력 제고 및 소비자의 안전 축산물에 대한 요구에 따라 무항생제 축산물에 대한 관심이 높아지고 있다. 이에 성장촉진용 항생제의 사용에 대한 규제가 강화되고 있으며, 항생제를 배제하고, 사육시 가축 생산성 저하 및 질병 발생 증가 등이 문제가 되고, 그 대응책이 시급한 실정이다. | |
현재 개발 중인 항생제 대체물질의 겪는 어려움은? | 일반적으로 항생제 대체제로서 많이 활용되는 성분은 항균성분과 항산화 성분이 많이 이용되는데, 항균성은 장내 유해 미생물을 억제하는 목적으로 사용되고 있으며, 항산화성분은 면역성 강화 목적으로 이용되고 있다. 하지만 현재 개발 중인 항생제 대체물질의 경우, 효과가 있더라고 제조 비용이 비싸거나, 비용이 저렴할 경우에는 항생제 대체효과가 미미하여 상용화하기 어려운 문제가 있다. |
