<abstract xmlns="http://www.w3.org/1999/xhtml"><p> This study was conducted to investigate the effects of Pleurotus eryngii stalk residue (PESR) on performance, egg traits and oxidative status of laying hens. One hundred and twenty 22-week-old laying hens (Hendrix) were randomly allocated into 4 dietary groups, each containing 30 birds, including 10 replicates per group and 3 birds per replicate. In addition, they were fed diets supplemented with 0 (control group, corn-soybean meal), 0.5, 1.0, or 2.0% dried PESR groups for 8 weeks, respectively. The results indicated that the different levels of dietary supplementation produced no significant differences in production performance among the experimental groups of laying hens.

The eggs’ cholesterol content of the 1.0% and 2.0% PESR groups was significantly lower than that of the control group at 5-8 weeks.
