Yacon (Smallanthus sonchifolius) root extracts affect laying performance, egg quality, serum biochemical parameters and intestinal microbiota in hens.
Objective: The objective of this study was to investigate the influence of yacon root extracts (YREs) on productive performance and health of laying hens.
Methods: Six hundred 30-week-old Xiaoshan Chicken layers were divided into 5 groups, control group, antibiotic positive control group, and 3 YREs treatment groups. In a 9-wk feeding experiment, at the end of wk 3, 6, and 9, twenty eggs were collected from each replicate to measure egg qualities. At the end of wk 9, three hen serum samples, and 5 hen cecal content samples were collected from each replicate.
Results: Compared to the control group, 0.8%, 1.6%, and 2.4% YREs treatments could increase hens' daily feed intake, and YREs supplementation affected daily feed intake in linear manner. YREs did not change egg size, but 0.8% and 2.4% YREs changed egg shape by decreasing the egg shape index and sphericity, and 0.8% YREs tended to improve the eggshell breaking strength. Diet supplemented with 1.6% YREs might decrease yolk color grade but optimize the pH of thick egg white in fresh egg; moreover, 1.6% and 2.4% YREs might be helpful for eggs to inhibit water loss during storage, and YREs supplementation affected water loss rate in linear manner. 2.4% YREs could decrease the serum lactate dehydrogenases (LDH) level, and YREs supplemental levels linearly affected serum LDH content. Finally, YREs could enrich the diversity of intestinal microbiota of hens fed with 0.8% and be beneficial for the relative abundance of phylum Bacteroidota and Halobacterota; 2.4% YREs might increase the abundance of phylum Actinobacteriota and genus Bifidobacterium, while decrease genus Bacteroides; YREs supplemental levels affected the abundance of phylum Actinobacteriota, and genera Bifidobacterium and Bacteroides in linear manner.
Conclusion: Dietary supplementation with YREs could affect egg quality, protect the health of organs and exhibit prebiotic activity.
