| چکیده | ||
| A 56-day feeding trial was conducted to find the potential effects of trisodium citrate (TSC) on the growth performance, immue response, and digestive enzymes of goldfish. The fish (n=150; 2.51±0.11 g) were randomly distributed into five groups with triplicates and fed with a basal diet without TSC (control diet) and four levels of TSC (5, 10, 15, and 20 g kg-1) for eight weeks. Results showed that TSC supplemented diets markedly enhanced the final weight, specific growth rate, feed conversion ratio, and feed intake (p <0.05). Moreover, serum immune parameters such as total immunoglobulin, lysozyme, and complements (C3 and C4) were significantly increased with the supplementation of dietary TSC (p <0.05). Furthermore, protease, lipase, and amylase values were profoundly increased with the increments of dietary TSC compared to the control group (p <0.05) and they were almost doubled in the fish fed with TSC at 20 g kg-1 TSC compared to the control. Taken together, the optimum dosage of TSC supplementation was 20 g kg-1 in terms of growth efficiency, immune parameters, and digestive enzymes for juvenile goldfish. | ||
