摘要

Juvenile rainbow trout Oncorhynchus mykiss diets containing PepSoyGen, a commercially-available fermentedsoybean meal product, were supplemented with methionine and other amino acids. A fish meal-based control and four experimentaldiets were used in a 36-day feeding trial; two diets contained 40% PepSoyGen and 10% fish meal, and two dietscontained 50% PepSoyGen and no fish meal. Each of these diets was supplemented with either methionine, or methionineand additional amino acids. One mortality was observed during the trial. Overall weight gain, percent gain, andfeed conversion ratio were significantly greater for the fish meal control than for any of the PepSoyGen diets, althoughfeed conversion ratios from all of the diets were still below 1. Apparent protein digestibility was significantly less in thefish receiving the control diet compared to any of the experimental diets, and significantly increased with increasing Pep-SoyGen concentrations. There was no significant difference in length, weight, condition factor, hepatosomatic index, viscerosomaticindex, or any fish health responses among dietary treatments. Fillet composition, as determined by crude protein,crude lipid, water, and ash, was also not significantly different among fish reared on any of the diets. The supplementationof other amino acids in addition to methionine had no noticeable effect. The results from this study indicate thatPepSoyGen with amino acid supplementation can completely replace fish meal in juvenile rainbow trout grower dietsover a relatively short time-frame, albeit with some decrease in rearing performance.
