摘要： This experiment was conducted to study the effects of arginine supplementation on organ development, egg quality, blood parameters, and immune status of laying hens. A total of 360 25-week-old brown Leghorn laying hens were randomly divided into three groups with six replicates of 20 birds each and fed diets supplemented with 0, 8.5, or 17 mg of L-arginine/kg for 42 days. Results showed that the weight of proventriculus and duodenum in the treatment supplemented with 17 mg/kg L-arginine was heavier than that of 0 mg L-arginine/kg treatment (p< 0.05). The weight of oviduct in the treatments supplemented with 17 mg/kg L-arginine was smaller than that of 0 and 8.5 mg L-arginine/kg treatment (p< 0.05), and the small yellow follicle amount in the treatment supplemented with 17 mg/kg L-arginine was less than that of 0 mg L-arginine/kg treatment (p< 0.05), while its yolk color was deeper than that of 0 mg L-arginine/kg treatment (p< 0.05), and the IgY content showed the same tendency. Total cholesterol and triglyceride levels in the treatment supplemented with 8.5 mg/kg L-arginine were lower than that of 0 mg L-arginine/kg treatment (p< 0.05). The concentration of IL-2 in the treatment supplemented with 17 mg/kg L-arginine were more than that of 0 mg L-arginine/kg treatment (p< 0.05). The findings of this study show that 17 mg/kg L-arginine supplementation has beneficial effects onlayers' immune status and yolk IgY content, as well as on proventriculus and duodenum weight while no adverse effects were observed on laying performance, egg quality, or blood parameters.
