摘要： This study aimed to evaluate the effects of adding Moringa oleifera leaf powder (MOLP) to the basal diets of chickens at late laying period on clutch trait, reproductive organs, serum reproductive hormones and reproduction-related genes expression. A total of 350 hens (37 weeks old) with similar laying rate and clutch trait were randomly allocated into five groups, and fed 0 (Control, CON), 2.5 (MOLP2.5), 5, 7.5 and 10% MOLP supplemented diets for 6 weeks. The hens supplemented with 2.5% MLOP had the average clutch length, clutches and clutch intensity close to those in CON. The numbers and weight of hierarchal follicle were significantly increased at the supplementation 2.5% MOLP group. The estrogen concentration was highest in MOLP2.5 group and lowest in MOLP10 group. Expression levels of steroidogenesis-related genes of StAR and Cyp19a1 were higher in MOLP2.5, MOLP5 and MOLP7.5 groups compared with that in the control. These findings suggested that dietary supplementation with 2.5% MOLP effectively increased hierarchal follicle numbers, estrogen level and gene expression of StAR and Cyp19a1, which has a potential beneficial effect on laying performance in laying chicken.
