Regulatory effects of hawthorn leaf flavonoids and stevioside on the uterine function and eggshell quality in laying hens.

ABSTRACT: This study aimed to investigate the effects of hawthorn leaf flavonoids (HF) and stevioside (ST) on eggshell quality, uterine function of the oviduct, and microbial composition in laying hens. A total of 630 Jing Tint 6 laying hens aged 66 weeks with similar body weights (1.8 ± 0.2 kg) were randomly divided into 7 groups with 6 replicates of 15 hens each. The control group (CON) was fed a basal diet, while the treatment groups were supplemented with 120 mg/kg HF (HF120), 120 mg/kg ST (ST120), 120 mg/kg HF + 120 mg/kg ST (HF120+ST120), 120 mg/kg HF + 60 mg/kg ST (HF120+ST60), 60 mg/kg HF + 120 mg/kg ST (HF60+ST120), and 60 mg/kg HF + 60 mg/kg ST (HF60+ST60) for 8 weeks. The results indicated that the combined dietary supplementation of HF and ST significantly improved eggshell strength, thi
