AI Technical Summary
Technical Problem
In the later stages of egg production, laying hens experience ovarian aging, decreased egg production, and deteriorating egg quality, leading to a decline in production performance. Existing technologies are insufficient to effectively improve their antioxidant capacity and egg quality.
Method used
By combining chicken saliva with Lactobacillus RS-11-1, probiotics or postbiotics can be prepared and added to laying hen feed to enhance their antioxidant capacity and egg quality.
Benefits of technology
It significantly improves the egg production rate, egg weight, eggshell strength, yolk color and Haugh units of laying hens in the later stages of egg production, reduces the feed conversion ratio, enhances the antioxidant capacity of laying hens, and improves egg quality.

Abstract
This invention discloses the application of chicken-derived *Ligilactobacillus salivarius* in late-laying laying hens. The *Ligilactobacillus salivarius* is used to prepare products that improve the production performance, antioxidant capacity, and / or egg quality of late-laying laying hens. The chicken-derived *Ligilactobacillus salivarius* is RS-11-1, classified as *Ligilactobacillus salivarius*, and was deposited at the China General Microbiological Culture Collection Center on November 12, 2024, with accession number CGMCC No. 32589. The chicken-derived *Ligilactobacillus salivarius* of this invention can improve intestinal health, enhance intestinal antioxidant capacity, and improve egg production performance and egg quality in late-laying laying hens.
