This study was conducted to evaluate the optimum dietary protein level in juvenile river puffer. Five semi-purified diets were formulated by using casein to contain graded levels of protein levels of 35, 45, 50, 55 and 65%. Fish averaging

단백질이란? | , 2001). 단백질은 동물의 체조직의 주된 유기물로서, 고형물 함량으로 환산 시 약 65~75%를 차지한다. 동물이 단백질을 섭취하는 것은 단백질합성에 필요한 필수아미노산의 공급과 비 필수 아미노산의 합성을 위한 질소성분의 공급을 위함이다(Kim et al. | |
어종에서 단백질 요구량은 어떤 요인에 영향을 받는가? | 단백질 요구량이란 필수아미노산 요구량을 충족시키고 비필수아미노산의 및 그 외 질소를 함유한 주요 대사물질의 합성에 필요한 질소성분의 요구량 충족을 위한 최소량을 의미하는데, 현재까지 많은 어종에서 단백질 요구량이 평가되었다(NRC 2011). 일반적으로 어류의 단백질 요구량은 어체의 크기, 수온, 사료단백질의 품질 및 에너지 함량과 같은 요인에 영향을 받을 수 있으며, 사료 내 단백질 요구량을 충족시키지 못할 경우 성장과 사료효율의 저하현상이 나타난다(Yoo et al., 2006). | |
단백질을 섭취하는 이유는? | 단백질은 동물의 체조직의 주된 유기물로서, 고형물 함량으로 환산 시 약 65~75%를 차지한다. 동물이 단백질을 섭취하는 것은 단백질합성에 필요한 필수아미노산의 공급과 비 필수 아미노산의 합성을 위한 질소성분의 공급을 위함이다(Kim et al., 2004). |
