In the egg creation industry, minor components are expected as extra dietary enhancements to assume crucial parts in execution and egg quality. Contrasted with inorganic microelements (ITs), suitable portion of natural follow microelements (OTs) are harmless to the ecosystem and adequate to fulfill the necessities of hens. To assess the degree to which low-portion OTs supplant entire ITs, the impacts of natural copper, zinc, manganese, and iron compound on the presentation, eggshell quality, cancer prevention agent limit, resistant capability, and mineral affidavit of old laying hens were explored. A sum of 1 080 57-week-old Jing Hong laying hens were relegated to five gatherings with six imitates of 36 layers each for a 8-week exploratory period. The birds were taken care of either a basal eating routine (control treatment (CT)) or the basal eating routine enhanced with business levels of inorganic minor components (IT 100 percent) or the same natural minor components at 20%, 30%, and half of the inorganic components (OT 20%, OT 30%, and OT half, individually). Results showed that contrasted and those in the CT treatment, taking care of hens with inorganic or natural microelement diet fundamentally affected the eggshell quality, cell reinforcement limit, resistant capability, and mineral testimony of old laying hens (P < 0.05). The eggshell strength and proportion between OT 30%, OT half, and IT 100 percent were comparative at weeks 4 and 8, and the eggshell thickness of these gatherings was likewise comparable at weeks 6 and 8. At week 8, the eggshell tone in OT half was hazier than that in IT 100 percent. The mineral substance in the eggshells of OT half and IT 100 percent altogether expanded (P < 0.001), with no tremendous contrast in successful thickness, mammillary thickness, and mammillary handle width between gatherings.
