| This study evaluated the effect of dietary L-glutamic acid supplementation in four dietary treatments, including Control (without added L-glutamic acid), 0.5, 1, and 2% L-glutamic acid added to the base diet, on rainbow trout (Oncorhynchus mykiss) juveniles (15-16 g). At the end of the 60-day culture period, growth performance, antioxidant status, amino acid composition, and muscle quality were assessed. The results showed that the 1% L-glutamic acid diet produced the highest weight gain (101.29 g) and the lowest feed conversion ratio (0.71) (p≥0.05). The fish fed the diet supplemented with 0.5% exhibited the highest activities of glutathione peroxidase, superoxide dismutase, and catalase, as well as the highest glutathione levels (p ≤ 0.05). However, dietary treatments had no significant effect on the proximate composition of muscle tissue. Similarly, dietary L-glutamic acid did not markedly alter the amino acid composition of muscle. The highest ΔE (7.86, color difference compared with the control) and muscle hardness (11.68 N) were observed in fish fed a 2% L-glutamic acid diet (p≥0.05), whereas the highest water-holding capacity (90.39%) and lowest cooking loss (23.32%) (p≥0.05) were recorded in the 1% group. Overall, dietary supplementation with L-glutamic acid could improve muscle antioxidant status (at 0.5%) and growth performance and muscle quality (at 1 and 2%) of rainbow trout. | ||
