초록

참전복 치패용 배합사료 원료로서 모자반의 이용성을 조사하기 위하여 대조사료의 어분, 대두박 및 소맥분을 모자반으로 각각 10%씩 대체한 배합사료를 제조하여 평균체중 428 mg의 참전복을 대상으로 사료당 4반복으로 130일간 사육실험하였다. 생존율은 89~95%로 모든 실험구간에서 양호한 결과를 보였다. 증중량은 소맥분을 모자반으로 대체한 실험구가 대조구와 대두박을 모자반 대체한 실험구보다 유의하게 높았으며 (P<0.05), 어분을 모자반으로 대체한 실험구는 타실험구와 차이를 보이지 않았다 (P>0.05). 가식부의 수분, 회분과 지질 함량은 실험구간에 서로 유의차가 없었으며 (p>0.05), 단백질 함량은 대조구에서 가장 높은 값을 보였으나 어분을 모자반으로 대체한 실험구와는 유의차가 없었다 (P>0.05). 위와 같이 참전복 배합사료에 어분이나 소맥분을 각각 모자반으로 10% 정도 대체할 수 있어 참전복 배합사료의 단백질원에 대한 단가를 절감시킬 수 있을 것으로 기대된다.

To test survival growth of juvenile abalone, five different diet were constituted. Diet 1, the control, was constituted with white fish meal (15%), soybean meal (25%) and wheat flour (25%); diets 2,3 and 4 were constituted to replace each one of these ingradietns by supplementing Sargossum powder (upto 10 %) and the fifth one by Undularia powder. Survival of these abalones differed significantly. Diet 4 supported the fastest growth. There was no significant difference in the composition of these abalones hence Sargassum can be used as a substitute.
