Problems solved by technology

The narrow living space and heavy production load lead to two serious problems in the late stage of laying hens: first, the function of the glands that secrete reproductive hormones is gradually declining, and the pituitary glands secrete follicle hormones, progesterone P4, and estradiol. The concentration of various hormones gradually decreases, resulting in the restriction of follicular development, the reduction of ovulation, and the decline of egg production rate; The thinner the eggshell, the worse the eggshell quality, and the egg breaking rate increases
At present, most dietary formulas only increase the calcium content to improve the eggshell quality and the egg production performance of laying hens. Absorbed in the tract, fundamentally improve the laying performance of laying hens

Abstract

The invention provides a feed additive for improving egg laying performance of laying hens. The feed additive is prepared from the following raw materials in parts by mass: 0.05-0.1 part of a compoundmicroelement, 1-2 parts of alpha-ketoglutarate, 3-6 parts of daidzein, 3-5 parts of cinnamaldehyde, 10-20 parts of astragalus polysaccharide, 3-5 parts of gamma-aminobutyrate, 12-18 parts of glucoseoxidase, 10-20 parts of living bacteria and 20-30 parts of calcium hydrophosphate; the compound microelement contains zinc methionine, selenium yeast, ferrous lactate, chromium picolinate, manganese sulfate and calcium iodate, and the living bacteria containbacillus subtilis, lactobacillus plantarum, bacillus licheniformis and bacillus coagulans. The feed additive has a remarkable use effect and the high utilization rate, meanwhile the problem that feed is polluted by mycotoxins can be solved, finally the body endocrine balance is maintained, the balance of intestinal flora is adjusted, the absorption of nutrients by the body is promoted, the immunity of the body is enhanced, thus the egg laying rate of the laying hens is increased, the egg quality is improved, and the death and culling rate of the laying hens is decreased.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a feed additive for improving the laying performance of laying hens and a preparation method thereof. Background technique [0002] In modern laying hen production, in order to maximize production efficiency, intensive cage production is often used. The narrow living space and the excessive production load lead to two serious problems in the late stage of egg production. The concentration of various hormones gradually decreases, resulting in restricted follicle development, decreased ovulation, and decreased egg production rate; The thinner the shell, the worse the eggshell quality, and the increased egg breaking rate. Publication number CN109123181A provides a premixed feed for improving the bone density and eggshell quality of laying hens and a preparation method thereof, belonging to the technical field of laying hen feed. It includes the following compo...
