Problems solved by technology

[0004] At present, there are five types of eggshell problems in commercial eggs: (1) broken due to excessive pressure; (2) cracked due to thin eggshell; (3) lines appear on the eggshell; Granules or small holes; (5) soft or shellless eggs
Feeds are poorly targeted and have limited effects on improving eggshells

Embodiment 1

[0024] To verify the improvement of egg quality of 50-week-old Hy-Line brown eggs by a feed additive that solves the eggshell quality in the late laying period of the present invention. The applicant carried out the application in a layer hen farm in Yangzhou. The trial date is from January 2018 to March 2018.

[0025] Test additives, the composition is as follows: 20 parts of fructooligosaccharides, 30 parts of fermented Eucommia leaves, 20 parts of Bacillus subtilis, 4 parts of Enterococcus faecalis, 10 parts of sodium bicarbonate, 2 parts of vitamin C, 1.5 parts of zinc, 0.2 parts of copper, manganese 1.5 parts, 10.8 parts of zeolite powder. The addition ratio is 0.5%. The test period is 60 days. The basic feed is the post-feed of laying hens. The 500 laying hens in the control group were divided into 5 repetitions, 100 feathers in each repetition, and fed with the basic diet; 0.5% additive of the present invention.

[0026] During the whole test period, normal feedin...

[0035] It is verified that a feed additive that solves the eggshell quality in the late laying period of the present invention can improve the quality and production performance of Roman pink eggs. The applicant carried out the application in a Roman pink laying hen farm in Ruicheng County, Shanxi Province. The trial date is from February 2018 to March 2018.

[0036] Test additives, the composition is as follows: 22 parts of fructooligosaccharide, 23 parts of fermented Eucommia leaves, 21 parts of Bacillus subtilis, 5.2 parts of Enterococcus faecalis, 7 parts of sodium bicarbonate, 2.7 parts of vitamin C, 17 parts of zinc, 0.1 part of copper , 1.2 parts of manganese, 16.1 parts of zeolite powder. The addition ratio is 0.5%. The test period is 30 days. The basic feed is the post-feed of laying hens. The 600 laying hens in the control group were divided into 6 repetitions, 100 feathers in each repetition, and fed with the basic diet; 0.5% additive of the present invention. ...

Embodiment 3

[0052] It is verified that a feed additive that solves the eggshell quality in the late laying period of the present invention can improve the quality and production performance of Roman pink eggs. The applicant carried out the work in a Roman pink laying hen farm in Weinan City, Shaanxi Province. The test layer was 310 days old, and the test date of Roman powder layer was from March 2018 to May 2018.

Abstract

The invention designs a feed additive for improving quality of eggshells in later laying period and a preparation method thereof and belongs to the field of feed additives. The feed additive is used for solving the problems of quality of eggshells in later laying period and production performance and contains the following raw materials: 15-20 parts of fructo-oligosaccharide, 20-30 parts of fermented folium cortex eucommiae, 15-20 parts of bacillus subtilis, 4-5 parts of enterococcus faecalis, 8-10 parts of sodium bicarbonate, 2-2.5 parts of vitamin C, 1.5-2 parts of zinc, 0.1-0.3 part of copper, 1-1.5 parts of manganese and 10-15 parts of zeolite powder. The invention adopts a compound nutrition technology for comprehensively increasing health level of laying hens and use ratio of calcium, phosphate and the like, promoting anti-stress capacity of the laying hens in later laying period, increasing eggshell thickness and eggshell strength, reducing loss cost of eggshells, relieving thedecreasing of laying rate, increasing egg weight and promoting production performance of laying hens.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to a feed additive for improving eggshell quality in the late laying period and a preparation method thereof. Background technique [0002] The overall structure of the eggshell is composed of inorganic and organic substances. Inorganic substances account for 94%-97%, mainly including: 93% calcium carbonate, 1% magnesium carbonate and 2.8% mixture of calcium carbonate and magnesium carbonate, as well as copper, Iron, manganese, zinc, selenium and other trace elements. Organic matter accounts for 3%-6%. The organic matters play the role of binding the inorganic matter together, and the content of the two plays a decisive role in the quality of the eggshell, directly affecting the thickness and density of the eggshell. The microstructure of eggshell is composed of inner shell membrane, papillae layer, palisade layer, crystal layer and epidermis layer, and its different hier...
