Description
Technical field
The invention belongs to animal feed microelement pre-mix material field, more particularly to improves the micro- of later stage eggshell quality that lay eggs
Trace mineral feed.
Background technology
The problem of breakage of egg is one extremely serious in the production of aviculture.With carrying for extensive intensive degree
Height, this problem are more prominent.According to foreign countries, the breakage of general egg accounts for the 6~8% of total egg production, it is annual it is Canadian by
Laying hen industry is set to suffer 10,000,000 dollars of l loss in broken egg.The annual every laying hen in the U.S. because it is damaged and caused by loss be about
1.38~2.0 dollars.China someone once made to last the sample investigation of half a year, and from egg into consumer's hand, rate of broken eggs is up to
LO%, very big economic loss is all brought to consumer and operator.
It is many to influence the factor of eggshell quality, including layer breed, feeding environment, trophic level, age in days of laying eggs etc. are many
Aspect.For ovipository cycle, laying hen is optimal in the quality of egg that 33 week old are produced, and is passed with the increase quality at age
Subtract.Later stage eggshell quality of laying eggs declines, and eggshell strength declines, and damaged egg increase, causes huge economic loss.
Micro- (Zn, Mn, Cu etc.) has directly influence on eggshell strength, parts of the Mn as enzyme, passes through
The glycosyl transferase during mucopolysaccharide is formed is activated, promotes the formation of Aggrecan, and regulates and controls crystal and extends along C axles, is promoted
It is correctly grown to regulate and control eggshell crystal structure and eggshell quality.Important components of the Zn as carbonic anhydrase, to providing egg
HCO in shell gland3 -Play an important roll.Confactors of the Cu as lysyloxidase, participation lysine metabolism and lysine
Conversion, participates in the formation of matrix film, therefore, lacks the distribution that copper can influence eggshell matrix film fiber, so as to cause deformity
Egg and abnormal mechanical property.Research shows that Zn, Mn, Cu are adjusted by the formation for influenceing eggshell and the structure for adjusting crystal
Save quality of egg.Meanwhile Zn, Cu are added under the conditions of heat stress, internal free radical is can remove, improves the anti-oxidant energy of body
Power, so as to improve body health state and improve Egg Quality.Shadow of the present invention according to trace element to later stage eggshell quality of laying eggs
Ring, ovipository cycle can be extended by developing one kind, improve the microelement pre-mix material for later stage eggshell quality of laying eggs.
Its technical basis：
Trace element has on eggshell quality directly to be significantly affected.
(1) influence of the manganese (Mn) to eggshell quality.
There is reciprocation between the element such as manganese and calcium, phosphorus, magnesium, zinc, people is particularly subject in terms of eggshell quality is improved
Attention.Czech F ri e d in 1985, K. have done experiment of the manganese to eggshell quality, calcic 2.8%, phosphorus 0.46% it is every
Add in kg. ration such as 60m g manganese, it will be apparent that improve eggshell quality and egg size, reduce breakage rate.It is many experiment find with
The increase eggshell of manganese amount is broken to take the photograph rate decline.High calcium, high phosphorus, using having an impact, have coordinative role to manganese between their threes.Family
Fowl nutritionist H o ba r t, R. make overtesting to the manganese compound of different shape, it was demonstrated that the activity of inorganic manganese source is with sulfuric acid
Manganese activity is best.
Manganese is that eggshell forms required trace element, and it plays an important role during synthetic protein-mucopolysaccharide
(Leach, 1969).Therefore manganese deficiency in feed, egg production and incubation rate reduce, eggshell thinning.Manganese content is down in feed
During 7mg/kg, and though in feed calcium, phosphorus content how much, can all cause eggshell quality to decline.NRC (1984) recommends laying hen manganese
Requirement is 30mg/kg, and the NRC of version in 1994 is then down to 20mg/kg.When the level of manganese in daily ration brings up to 55~
During 60mg/kg, eggshell quality is optimal.Saly etc. confirms that the laying hen to open the monthly age in postpartum 12 mends manganese, and eggshell is hardened, can significantly carried
High eggshell quality, reduce breakage rate.
The acid mucopolysaccharide content of eggshell is largely related to the breaking resistance of eggshell, and manganese is in the conjunction of mucopolysaccharide
Played an important role during.When manganese level brings up to 55~60mg/Kg in daily ration, eggshell quality is optimal.Manganese and zinc
Be metabolized in vivo it is in close relations, with Gao Meng (100mg/Kg) daily ration feed chicken can prevent egg from rupturing.Poultry is to the requirement of manganese than feeding
Newborn animal is high, and this is due to that poultry is relatively low to the utilization rate of manganese, and deposition in vivo is relatively low (being discharged with bile).
(2) influence of the zinc (Zn) to eggshell quality
Zinc is the part of many heavy enzymes, and the activity of kind of enzyme is relevant with zinc at least more than 160.Especially have to metalloenzyme
Catalytic, structural and adjusting sexual function, these enzymes mainly include oxidoreducing enzyme (superoxide dismutase), transferase
(RNA polymerase), hydrolase (alkaline phosphatase), lyases (carbonic anhydrase) and ligase (tRNA synzyme).Eggshell is in body
Carbonic anhydrase is needed in interior calcification process, it is in carbon dioxide and hydrone carbonate synthesis hydrogen radical IONS OF H CO3 -Balanced reaction in
Important catalytic action is played, and zinc is one of main component of this enzyme.Laying hen zinc-deficiency, carbonic anhydrase activity reduces, so as to influence
Eggshell is formed.Zinc-deficiency is the same with manganese deficiency, eggshell can be made to turn white.When phytic acid or too high calcium content, the absorption of zinc is substantially suppressed,
Then eggshell quality is had influence on.It is generally believed that laying hen needs daily ration 50mg/Kg containing zinc just to can guarantee that eggshell quality is normal.Zinc
Only it is added to simultaneously in layer dietses just effectively with manganese.
(3) influence of the copper (Cu) to egg quality.
Appropriate Cu is added in feed, aged laying hen eggshell quality can be improved, reduces Abnormal Eggss and rate of broken eggs.Experiment
Show that adding copper sulphate makes laying rate and feedstuff-egg ratio all improve.Copper is to maintaining the normal During Pregnancy of animal and breeding potential and hatching egg
Incubation rate have an impact, this may be relevant with the generation of red blood cell and the generation of connective tissue.
Copper is the confactor of lysyloxidase, and lysyloxidase can aoxidize collagen and elasticity in egg shell membrane
The special acid residue of albumen, collagen and elastin laminin is set to form covalent bond, copper also participates in the shape of stromatin film
Into the metabolism of middle lysine, lack the distribution that copper can influence eggshell stromatin film-based fibre, so as to cause lopsided egg.Copper and its
Its trace element cooperation, is significantly improved to eggshell quality.
(4) influence of sodium and chlorine to quality of egg.
One of an important factor for Dietary electrolyte balance is influence eggshell quality.During eggshell formation, by daily ration
The influence of many factors such as ionic equilibrium and alcium and phosphor metabolization.Excessive chlorine makes the intensity of eggshell and thickness significantly drop in daily ration
It is low.The pure city's report in village difficult to understand, adds 250 milligrams of mineral matter sodium chloride, 40 milligrams of potassium chloride, rupture egg, soft-shelled egg increase in drinking-water
Double, in drinking-water add salt 200,400,600 g/l, rate of broken eggs increases to 10.4%, 14.2% and from 6.5%
18.9%, it was reported that for laying hen using eggshell strength and thickness as index, the optimal proportion of sodium and chlorine is 1：0.6 (quality).Blood
NaHCO3Concentration be proportionate with eggshell quality.NaHCO is added in layer dietses3Improve eggshell quality, main cause is
NaHCO3Cause in blood alkali storage to be increased reduces with the concentration of phosphate radical, and the reduction of serium inorganic phosphorus concentration is advantageous to improve eggshell quality.
Experiment is confirmed, 0.1~0.5% (quality) NaHCO is added in feed3Salt is substituted, eggshell loss 1%~2% can be reduced.This
Outside, Dietary electrolyte balance value can also significantly affect eggshell quality, Vogt etc. (1983) discovery, DEB too low (68mEq/kg) or
When too high (296mEq/kg), eggshell thinning.When DEB is in more than 150mEq/kg, shell thickness rises and increased with DEB.Carry
High diet potassium content (bringing up to 0.88% (quality) by 0.66%), can improve quality of egg.General laying hen is in suitable for producing
In the range of Dietary electrolyte balance value, the normal quality of eggshell can be ensured.
Keep electrolyte balance：For chlorine in acidity in chicken body, high-caliber chlorine is harmful to eggshell.Because high chlorine produces
Metabolic acid can suppress carbonic anhydrase, hinder bicarbonate to be changed into carbonate；Suppress the 1- hydroxylases in kidney, harm simultaneously
Hinder 25- hydroxyls-vitamine D3 to be changed into active metabolite 1,25-2 hydroxyls-vitamine D3, influence alcium and phosphor metabolization in chicken body.And sodium
With potassium in chicken body in alkalescence, can be substituted mutually with 1: 1 mass ratio, with resist sodium containing normal amount, potassium daily ration in excess
Influence of the chlorine to eggshell.Research shows, in the normal daily ration of calcium phosphorus content, the equivalent of sodium+potassium-chlorine should at least meet
180mg/ kilograms of electrolyte balance, the salt of 0.1%~0.5% (quality) can be replaced with sodium bicarbonate, it is internal effectively to adjust
Acid-base balance, eggshell crack rate is reduced, add sodium bicarbonate, eggshell hardness can be improved.These mineral additives improve eggshell
Structure, so as to improve eggshell strength.
In summary, copper sulphate is the cupric feed addictive being widely used at present, and what this area used adds containing copper feed
It is cupric sulfate pentahydrate to add agent copper sulphate, and biological value is high, while also has the function that similar antibiotic, and feeding effect is good, easily
Absorb, cost is low, is widely used.Zinc sulfate is tested in laying hen and proved, in terms of eggshell strength is improved, is better than other including organic
Zinc source including zinc.Diet electrolyte balance can influence zwitterion ratio in blood, so as to influence the egg laying performance of egg fowl.Raise
Grain is chloride excessively seriously to reduce chicken feed intake and egg laying performance, be unfavorable for eggshell calcification.
