Abstract

The objective of this study was determining the influence of enriched feeding with vitamin C and E on growth and chemical composition of red tilapia (Oreochromis spp.). A completely randomized design was used in this experiment. No statistically significant differences were observed for humidity, while all other parameters evaluated in this study showed differences. The results obtained
showed enhanced growth in terms of size, weight and growth rate, and a 100% survival in the fish using the combination of vitamin C and E. The chemical characterization indicated that protein ranged from 20.36% to 21.56%, humidity from 73.04% to 76.52%, ash from 1.29% to 3.27% and ether extract from1.83% to 3.23% for treatments 1 and 4. The obtained results suggest that the fish growth increased and red tilapia steaks have high nutritional value using the fodder in combination with vitamin C and E.
