Availability of Soybean Meal and Suitable Protein${\cdot}$Energy Level in Different Types of Diet of Red Seabream (Pagurus major)

참돔 (Pagurus major) 치어용 사료에 있어서의 대두박의 이용성과 적정 단백질${\cdot}$에너지 함량

To test the availability of soybean meal as a protein source and to increase its effectiveness in the diets for the fingerlings of red seabream, some feeding trials were conducted. Two different types of diet, steam pellet and soft dry pellet, contained various levels of soybean meal, were used. The growth, feed efficiencies, and body compositions were examined after the feeding trials. Results of the experiments suggested that dietary protein level could be reduced from $52{\%}$ to $47{\%}$ by elevating dietary energy level from $13{\%}$ to $21{\%}$ with lipid. The best results of growth and feed efficiencies were achieved by the diet that containing $47{\%}$ of crude protein and $20{\%}$ of crude lipids. The growths and feed efficiencies showed no difference when $20{\%}$ of fish meal in the experimental diet were substituted by soybean meal. Therefore, $20{\%}$ of fish meal could be substituted by soybean meal without reducing growth rates or feed efficiencies of fingerling red sea bream.

참돔 치어에 있어서의 식물성단백질원의 이용성의 검토와 유효이용을 꾀하기 위하여, 대두박 및 콘글루텐 밀을 배합한 여러 종류의 실험사료를 제작하여 성장, 사료효율 및 어체성분에 미치는 영향을 조사하였다. 그 결과 사료중의 조단백질 및 조지폐함량이 각각 $47{\%}\;,20{\%}$ 구에서 뛰어난 성장 및 사료효율을 나타내었으며, 어분의 $20{\%}$를 대두박으로 대체하여도 성장 및 사료효율에는 아무튼 간제가 없는 것으로 판단되었다. 그리고, 원료대두박의 Ex 처리유무 및 사료의 제조법의 차이에 의한 영양가개선을 인정할 수 없었다.
