사료내 지방의 함량이 적정수준 이상 함유될 경우 단점은? | , 2011). 반면, 적정수준 이상 함유 될 경우 이용효율이 떨어지며 산화 될 우려가 있으므로 양식대상종의 배합사료 개발을 위하여 적정 지질요구량은 반드시 규명 되어야 한다. 지질요구량에 대한 연구는 senegalese sole (Morais et al. | |
체내에서 지질과 지방산의 역할은? | 지질은 사료의 에너지원으로 단백질이나 탄수화물보다 에너지가가 높아 값비싼 단백질 사료원료를 절약할 수 있는 중요한 에너지원일 뿐 아니라, 지용성 비타민을 공급하는 중요한 영양소이다(NRC, 2011). 또한, 체내에서 지질과 지방산은 지용성비타민의 흡수, 세포막 형성, 호르몬과 담즙 형성 및 체내 에너지 축적에 중요한 역할을 한다. 특히, 지질은 필수지방산의 공급원으로 양식 대상종의 성장과 체내대사에 필수적인 역할을 한다. 사료내 지질 수준을 증가시켜 단백질을 대체하면 생산단가를 낮출 수 있을 뿐만 아니라 질소배출을 감소시켜 환경오염에도 도움이 된다(Choi et al. | |
자연상태에서 어류를 위한 먹이내 주된 에너지 공급원은? | 자연 상태에서 어류를 위한 먹이내 주된 에너지 공급원은 지질이다. 대부분의 동물들은 먹이가 고갈될 때 체지방을 쉽게 에너지원으로 대사 시킬 수 있다. |
