Method for improving eggshell quality of laying hens in later egg laying period by adding lactobacillus salivarius into feed
By adding Lactobacillus salivarius to the diet of laying hens, the intestinal flora and calcium metabolism were regulated, which solved the problems of production performance and eggshell quality in the later stage of egg production, improved eggshell strength and thickness, and reduced the breakage rate.

AI Technical Summary
Technical Problem
Laying hens generally face declining production performance and deteriorating eggshell quality in the later stages of egg production. The application of probiotics in existing technologies lacks specificity and stability, resulting in insignificant effects.
Method used
By adding Lactobacillus salivarius to the basal diet, the gut microbiota structure is regulated, beneficial metabolites are produced, calcium metabolism genes are activated, and intestinal calcium absorption is improved, thereby increasing eggshell strength and thickness.
Benefits of technology
It significantly improves the production performance and eggshell quality of laying hens in the later stages of egg production, reduces the breakage rate, and provides a green and safe solution.

Abstract
The invention discloses a method for improving egg shell quality in the later egg laying period of laying hens by adding intestinal probiotics into feed, and belongs to the technical field of healthy poultry breeding. According to the method, specifically enriched lactobacillus salivarius is screened based on correlation analysis of intestinal flora and eggshell quality. The strain is added into basic ration of laying hens in the later egg laying period according to a certain proportion (preferably 150 mg / kg feed) in the form of bacterial powder with the viable count not lower than 1 * 10 < 9 > CFU / g, and the laying hens are continuously fed for at least 8 weeks. According to the method, the laying rate and the average daily egg weight of the laying hens in the later laying period can be remarkably increased, the eggshell thickness and strength are effectively improved, and the egg breaking rate is reduced. The strain screening method provided by the invention is scientific, clear in application effect, safe and free of residues, and an effective green solution is provided for solving the problem that the eggshell quality is reduced in the later egg laying period of laying hens.
