Egg-laying rate, serum melatonin, and antioxidant enzyme activities were alleviated by fecal microbiota transplantation from a resveratrol supplementation diet (Exp.2). Data are means ± SEM represented by vertical bars or plot individual values ± SEM. (A) Egg-laying rate. (B,C) Serum tryptophan and kynurenine levels. (D-F) Serum antioxidant capacities. CON = control, OS = oxidative stress (injection of 800 μmol/kg BW of tBHP), OSR = CON + 600 mg/kg resveratrol; FMTCON, FMTOS and FMTOSR indicated the microbiota-depleted layers received microbiota transplantations from donor layer treated CON diet, tBHP, and OSR, individually; MDA = malondialdehyde, PC = protein carbonyl, T-AOC = total antioxidant capacity, SOD = superoxide dismutase, GSH = glutathione, GSH-ST = glutathione S—transferase, GSH-Px = glutathione peroxidase. Statistical significance was evaluated by the Turkey’s T-test, p < 0.05.
