抄録

The nutritive value of several soy proteins was evaluated for fingerling yellowtail Seriola quin-queradiata on the basis of chemical analysis and feeding experiments with moist pellet diets contain-ing 30% of each protein source. Trypsin inhibitor (TI) activity and antigen concentration tended to decrease with heating a raw soybean meal (SBM) and with extruding heated SBM. The protein content increased and the sugar content together with TI activity decreased with the purification and en-zymatic hydrolysis of SBM. However, the amino acid composition hardly changed with these treat-ments.<br> Dietary supplementation of raw SBM caused a weight loss in the fish with quite poor hematologi-cal characteristics, while that of heated SBM improved the growth and feed conversion, but it is in-ferior to a control group fed a diet without soy protein. Dietary supplementation of soy protein con-centrate, soy protein separate or soy protein peptide showed a similarly better growth performance and was comparable to the control group. These results indicate that the nutritive value of soy protein is markedly improved by purification together with heating. It is also suggested that the heating treatment is essential and alcohol purification is sufficient to use SBM for the fish feed.
