Abstract
The present invention relates to a kind of feed addictives improving Egg Production of Laying Hens later stage eggshell quality, it includes that following components mixes, and the composition by weight is：58 parts of rodrigo Hy.d, 500 1000 parts of hydroxy methionine analog chelated zinc, 500 1000 parts of hydroxy methionine analog Chelated Manganese, 500 1000 parts of hydroxy methionine analog chelated copper, 20,000 30000 parts of microlith powder, 50,000 60000 parts of middling flour.Feed addictive of the present invention can improve eggshell strength and thickness, reduce the breakage rate of egg.
Description
Technical field
The present invention relates to a kind of Egg Production of Laying Hens later stage mixed feeds, and in particular to a kind of raising Egg Production of Laying Hens later stage eggshell matter
The feed addictive of amount.
Background technology
Eggshell quality is one of the important indicator for weighing performance in layers, although having continued closely to the research of eggshell quality
70 years, eggshell inferior was still a major reason for causing laying hen industry economic loss；Nearly 30 years, although eggshell quality is carried
Height, still, the breakage rate of general specialist poultry is still 2.0%-4.5%, and some is up to 10.0%, in addition classification, packaging,
The loss in cargo handling operations such as transport, storage and processing, loss late caused by eggshell crack about 6.0%-10.0% it
Between.For the economic loss that the U.S. is brought to aviculture by eggshell quality problem up to more than 100,000,000 dollars, therefore China causes economic damage every year
It loses up to more than 500,000,000 yuan.With the growth of Egg Production of Laying Hens week old, egg size increases, and egg body increases, and is deposited on the calcium in eggshell and is substantially
Stable, body remains unchanged calcareous aggregate amount, therefore the thickness of eggshell just necessarily declines, and eggshell thinning becomes fragile.In addition,
Calcium uptake utilizes in later stage body of laying eggs is to feed, persistence declines, and the calcium amount formed for eggshell is caused to decline therewith,
Eggshell weight does not increase, and causes eggshell strength and shell thickness to be deteriorated, breakage rate increases.Therefore, the Egg Production of Laying Hens later stage is improved
Eggshell quality is urgent problem.
Invention content
The technical problem to be solved by the present invention is to the problems in for the above-mentioned prior art, provide a kind of raising laying hen production
The feed addictive of egg later stage eggshell quality enhances shell thickness and intensity, reduces the breakage rate of egg.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is as follows：
A kind of feed addictive improving Egg Production of Laying Hens later stage eggshell quality, it includes that following components mixes, described
Component is calculated by weight as：5-8 parts of rodrigo Hy.d, 500-1000 parts of hydroxy methionine analog chelated zinc, hydroxyl egg ammonia
500-1000 parts of acid-like substance Chelated Manganese, 500-1000 parts of hydroxy methionine analog chelated copper, microlith powder 20000-30000
Part, 50000-60000 parts of middling flour.
By said program, the Zn content of the hydroxy methionine analog chelated zinc is 3.0%-5.0%, hydroxy methionine
Content >=22.0%.
By said program, the manganese content of the hydroxy methionine analog Chelated Manganese is 0.7%-1.5%, hydroxy methionine
Content >=22.0%.
By said program, the copper content of the hydroxy methionine analog chelated copper is 0.6%-1.0%, hydroxy methionine
Content >=22.0%.
By said program, the middling flour is 8-12 mesh mountain flours, and the microlith powder is 15-20 mesh mountain flours.
When in use, the mass percent that feed addictive of the present invention accounts for feed total amount is 8.0-11.0%.
The Egg Production of Laying Hens later stage feed for including above-mentioned additive includes by weight percentage：Yellow maize 60-65%, wheat
Bran 3-5%, dregs of beans 15-20%, corn protein powder 2-4%, soya-bean oil 0.8-1.2%, calcium monohydrogen phosphate 0.7-1.0%, methionine
0.08-0.12%, lysine 0.14-0.16%, choline chloride 0.08-0.12%, NT03 laying cycle of laying hens compound premixing, which close, raises
Expect 0.2-0.3%, sodium chloride 0.2-0.4%, system chaff 0.4-0.8% and above-mentioned additive 8-11%.
The present invention in Egg Production of Laying Hens later stage mixed feed by adding rodrigo Hy.d, hydroxy methionine analog chelating
Zinc, hydroxy methionine analog Chelated Manganese, hydroxy methionine analog chelated copper can promote calcareous absorption.Rodrigo Hy.d is
The free-flowing spray drying 25-hydroxyvitamin D3 powder of Royal DSM company production, it need not be converted into 1,25- in animal's liver
Hydroxyl-D3 is not influenced by stress factors such as fat, bile, intestinal inflammatory or damages, can directly adjust calcium phosphorus in animal body
Metabolism promotes the absorption of calcium phosphorus in small intestine；Metal ion in vivo is mostly to exist in the form of chelate, chela
The chemical property for closing object is very stable, and this structure and property are particularly important in vivo.Microelements aminophenol chelated was both
It is the principal mode that body absorbs metal ion, and is the important intermediate material of synthetic protein in animal body, not only absorbs soon,
And many biochemical processes can be reduced, energy i (in vivo) is saved, biological value is improved.Eggshell needs in calcification process in vivo
Carbonic anhydrase, it plays important catalytic action in the balanced reaction of carbon dioxide and hydrone carbonate synthesis hydrogen radical ion, and
Zinc is one of main component of this enzyme.Laying hen zinc-deficiency, carbonic anhydrase activity are reduced, are formed to influence eggshell.The same manganese deficiency of zinc-deficiency
Equally, eggshell can be made to whiten.The absorption of zinc is obviously suppressed when phytic acid or excessively high calcium content, then influences eggshell quality.
Manganese is formed with eggshell, the intensity of eggshell is related, manganese deficiency in feed, and acidic mucopolysaccharide content is reduced in eggshell, makes eggshell unit weight
Amount declines, eggshell thinning, and crack egg ratio rises, and egg breaks rate and improves.The active shadow that copper passes through the copper containing lysyloxidase
Ring the formation of egg shell membrane；Slightly, microlith powder scientific matching, middling flour release is calcareous relatively slow, can keep the concentration of calcium in blood
It is persistently balanced.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) using the laying hen of feed addictive of the present invention, shell thickness and intensity enhancing, the breakage of egg is reduced
Rate, produced eggshell strength is in 4.0-4.5kgf, shell thickness in 0.40-0.45mm, the low 2-3% of fresh egg breakage rate；
(2) present invention is given birth to digestible aminoacids, anti-stress nutrition Technology design feed formula rich in the Egg Production of Laying Hens later stage
Various amino acid, vitamin, trace quantity mineral substance element necessary to production, do not add any harmful substance, green, safe and environment-friendly.
Specific implementation mode
For a better understanding of the present invention, with reference to the embodiment content that the present invention is furture elucidated, but the present invention is not
It is limited only to the following examples.
In following embodiment and comparative examples, the Zn content of hydroxy methionine analog chelated zinc is 3.0%, hydroxy methionine
Content 22.0%；The manganese content of the hydroxy methionine analog Chelated Manganese is 0.77%, the content of hydroxy methionine
22.0%；The copper content of the hydroxy methionine analog chelated copper is 0.75%, the content 22.0% of hydroxy methionine；It is described
Middling flour is 10 mesh mountain flours, and the microlith powder is 16 mesh mountain flours；Mountain flour is the product of the mountains Jing Shan Jie Zi calcium powder factory production.
