| Abstract;Knowledge concerning the digestive compensation of yellowtail Seriola quinqueradiata for dietary soybean trypsin inhibitor(SBTI) in necessary for developing soybean meal(SBM) diets. The fish, weighing 22.5g on an initial mean body weight, were fed diets supplemented with soybean trypsin inhibitor(SBTI) at the levels of 0,0.6,1.2, and 3 trypsin inhibitor units/mg diet at 22.DEG.C. for 25 days. The dietary SBTI doses induced no significant influences on protein digestibility, final mean body weight, final digestive organ-somatic index, final carcass and liver proximate compositions, acidic proteinase(AP) activities in gastral digesta, and basic proteinase(BP) and SBTI insensitive-BP(TI-BP) activities in enteral digesta after feeding. Enteral digesta weight decreased with an increase in dietary SBTI levels at 3h after feeding. Gastral tissue AP activity at 6h after feeding and enteral tissue(including pyloric caeca) BP and TI-BP activities at 3 and 6h after feeding tended to be higher in the fish fed the diets with SBTI than the fish fed the diet without SBTI. These results suggest that the digestive function of yellowtail is fully able to compensate for dietary SBTI doses, due to the low sensitivity of BP for SBTI. Therefore, SBM limitation in diets of yellowtail is due to antigenic proteins and other antinutritional factors, singularly or plurally, rather than only SBTI. (author abst.) |
