The experiment was carried out to investigate the effect of tryptophan, melatonin and dimethylglycine on the growth performance and meat quality of Japanese quails fed diets contaminated with aflatoxin B1 toxin. In this experiment, 680 Japanese quail from 7 to 35 days of age were allotted to 17 treatments and 4 replicates (10 birds per replication), and trial performed using a central composite design. The performance of birds was calculated on a weekly basis and at the end of the experiment; and the amount of malondialdehyde in meat was determined. Results showed that tryptophan increase weight gain and melatonin had an increased effect on feed intake (P < 0.05). The effect of tryptophan and as well as the interaction of tryptophan and dimethylglycine reduced the amount of malondialdehyde in meat (P < 0.05). The results obtained from this research state that dietary supplementation with tryptophan and methyl group donors have good antioxidant capacity to reduce aflatoxin B1 poisoning on growth performance and malondialdehyde content of meat, and the use of these supplements in the diet of Japanese quails seems desirable.
