Late-egg-laying-stage compound premixed feed for improving egg shell quality of laying hens

Abstract

The invention discloses a late-egg-laying-stage compound premixed feed for improving egg shell quality of laying hens. The compound premixed feed is prepared from, by mass, 10 parts of multivitamins,25 parts of compound trace elements, 18-22 parts of choline chloride in mass fraction of 50%, 36-44 parts of DL-methionine, 12-16 parts of L-lysine hydrochloride, 3-4 parts of phytase, 4-6 parts of acomplex enzyme agent, 3-4 parts of a probiotics, 90-110 parts of sodium chloride, 270-330 parts of calcium hydrogen phosphate, 240-305 parts of stone powder, 90-110 parts of spray-dried porcine globulin powder, 85-110 parts of montmorillonite and 1.5-3 parts of an antioxidant. The late-egg-laying-stage compound premixed feed is capable of improving immunity of the hens, stable egg laying performances and low feed-egg ratio are realized, broken eggs, cracked eggs and sandy shell eggs can be reduced, egg shells are dark in color, smooth and glossy, and eggs are high in quality, so that economicbenefits are increased.

Description

technical field [0001] The invention relates to a compound premixed feed for laying hens in the late laying period for improving eggshell quality, and belongs to the technical field of feed. Background technique [0002] For the poultry and egg production industry, good egg shell quality and egg internal quality are the key to the economic viability of poultry and egg production enterprises. my country is a big egg producing country. According to statistics, the annual egg production can reach more than 20 million tons, and the damage rate of chickens raised by general farmers can reach 2% to 4.5%, and some can reach as high as 10%. Losses in storage and processing links, the loss rate due to eggshell damage is about 6% to 10%. In addition, in recent years, the quality of eggshells has attracted more and more attention from consumers. In most regions, consumers prefer eggs with darker color, and eggs with poor color are not easy to sell. Therefore, the problem of eggshell q...

AI Technical Summary

Problems solved by technology

In the late stage of laying, the egg production performance of the flock gradually declines, the eggshell gradually becomes thinner, the breakage rate gradually increases to 3% to 4%, and the color of the eggshell gradually becomes lighter, which affects sales

On the other hand, due to the gradual decline of antibody levels in the late laying period, the resistance to diseases is also gradually weakened, and they are more sensitive to various stresses, resulting in an increase in death
