치어기 넙치(Paralichthys olivaceus)에 있어서 어분 대체원으로써 탈피대두박을 이용하여 생산한 오징어 간분의 평가

Abstract

This study was conducted to determine the proper inclusion levels of squid liver powder (SLP) and dehulled soybean meal (DHSM) as a fish meal (FM) replacement in the diets for olive flounders. All the experimental diets were formulated to be isonitrogenous (50% crude protein, CP) and isocaloric (17.1 kJ energy diet). Four diet were formulation of FM with SLP (DHSM) were tested at 0, 25, 50, 75% (SLP(DHSM), SLP(DHSM), SLP(DHSM) and SLP(DHSM), respectively). Triplicate groups of 12 fish with an average body weight of 5.560.1 g (meanS.D.) were fed one of three experimental diets for 7 weeks. Weight gain (WG) and the specific growth rate(SGR) of fish fed SLP(DHSM) and SLP(DHSM) diets were significantly higher than those of fish fed SLP(DHSM) and SLP(DHSM) diets (P had significantly higher WG and SGR than that of fish fed SLP(DHSM) (P and SLP(DHSM) were significantly higher than those fed SLP(DHSM) and SLP(DHSM) (P was significantly higher than that of fish fed SLP(DHSM) (P
