Abstract

The ingredients of animal origin have a good aminoacid composition, but often with great quantitative variation. This study evaluated the replacement of meat and bone meal by soybean meal with and without the use of synthetic lysine in the diet of common carp juveniles. An experiment was conducted with 35 days. Thirty-five fish were used in a water recirculation system. Three diets were tested: DA (diet with animal protein), DV (100% vegetable diet) and DV1 (DV diet supplemented with 1% synthetic lysine). After the experimental period, the following zootechnical parameters were estimated: mean weight, total and standard length, condition factor, specific growth rate, relative weight gain, survival and biomass. In addition, the centesimal composition of the fish was analyzed, where the fat, dry matter and mineral matter content of the carcass were determined. The amount of plasma glucose in carp was also measured. The results of weight, length and relative weight gain were higher in fish fed the DA diet. Fish fed with plant diets had higher glucose values. The diet with protein source of animal origin is the best option for the feeding of juveniles of common carp.
