This study aimed to investigate the effects of rutin on laying performance, egg quality, serum biochemical parameters, serum immunoglobulin, and antioxidant status in laying hens fed a diet containing stored soybean meal (SBM). The dietary treatments used were arranged in a 2 × 2 factorial arrangement with 2 types of SBM (FSM: SBM was stored in the cold storage warehouses at −20 °C for 45 days and was considered as fresh SBM; RTSM: SBM was stored in room temperature warehouse (15 °C to 25 °C), average temperature was 20 °C for 45 days) and 2 levels of rutin (0 and 500 mg/kg). In total, 384 Hy-Line Brown laying hens (220 days of age) were randomly divided into 4 groups with eight replicates. Pre-feeding period was 1 week, and the experiment lasted for 8 weeks. The results showed that the RTSM diet had no effect on laying performance (p > 0.05). Compared with the diet without rutin, diet with 500 mg/kg rutin exhibited a tendency to increase egg mass compared with the diet without rutin (p = 0.096), and there was a trend of interaction effect on average egg weight (p = 0.061). The RTSM diet decreased the egg Haugh unit significantly compared with the FSM diet at the end of 8th week (p
