Description
Technical field
The present invention relates to aquaculture management technical field, more particularly to a kind of method for reducing the hatching egg breakage of kind chicken house.
Background technology
As cost of material increases, the raising more and more higher of Breeder hens, the also more and more higher of cost shared by every piece of egg, cage meat
Breeder improves stocking density, and rate of fertilization is improved by artificial insemination, can reduce production cost to a certain extent, still
The breakage rate of this hatching egg can raise chickens height at least 1-2% than usual, in production, if the breakage rate of hatching egg is too high, will directly affect
To the economic benefit of chicken house.
The content of the invention
The defects of the object of the invention is exactly to make up prior art, there is provided a kind of to reduce kind of the damaged side of chicken house hatching egg
Method.
The present invention is achieved by the following technical solutions：
It is a kind of to reduce kind of the damaged method of chicken house hatching egg, comprise the following steps：
（1）Strict temperature, the humidity for controlling hen house, high temperature easily cause feed intake to decline, and nutrient intake reduces, calcium
Mineralization causes eggshell hardness to decline, and various stress factors are reduced during raising, avoid Breeding hens from getting a fright, cuts off the water supply, raise
Expect that composition change, illumination disorder etc. influence the eubolism of chicken body, cause egg unexpected damaged；
（2）The daily ration of antenatal 2 weeks feeding high calciums is opened in hen, various mineral matters, electrolytes and minerals are up to standard in daily ration,
And there is suitable ratio, to Breeding hens in the afternoon 16：Add the stone flour and oyster shell for feeding bulky grain after 00, improve egg shell
Hardness；
（3）Carry out breeder epidemic prevention to go out disease, the spraying disinfection into hen house of timing, the bad Breeding hens of diseased chicken or the state of mind are put
In independent chicken coop, the Breeding hens in same chicken coop are carried out with prevention from suffering from the diseases work, to improve hatching egg laying rate and qualification rate；
（4）The environment of laying eggs of clean hygiene is provided for Breeding hens, the design of laying nest should be reasonable, and trains breeder to be produced in case
Egg, floor egg is reduced, the design of laying nest ensures well-ventilated, egg is put into laying nest attracts Breeding hens to enter nest and lay eggs, female
Chicken should not disturb when laying eggs and walk about, when lay eggs terminate after egg collection, and increase egg collection number and prevent that mutually extruding is broken between hatching egg
Egg, the Breeding hens in all laying nests, which are removed and closed, after last time egg collection prevents from inhabiting in it, is filled under laying nest
Bottom set net, the iron wire of spacer screen should not be too thick, should have good elasticity, ensure the egg of output and can smoothly roll out and speed well；
（5）Superseded advanced age chicken group in good time, the bad chicken group of Egg quality is eliminated according to situation of laying eggs after breeder reaches 2-3；
（6）To be handled with care when artificially collecting hatching egg, using egg tray, after often disk hatching egg is put well, egg rack car should be put it to immediately
On, prevent from surprisingly breaking egg.
It is a kind of to reduce kind of the damaged method of chicken house hatching egg, step（2）Described in various mineral matters, vitamin and micro member
Element addition be：The optimum content of calcium is 3.3%-3.5% in daily ration, the optimum content of phosphorus is 0.7-0.9%, vitamin D, manganese,
Zinc, the addition of magnesium are 30 μ g/Kg, 200mg/Kg, 50mg/Kg, 400mg/Kg.
It is a kind of to reduce kind of the damaged method of chicken house hatching egg, step（2）Described in stone flour and the addition of oyster shell account for feeding
The 2-4% of material, both mass ratioes are 7：3.
It is a kind of to reduce kind of the damaged method of chicken house hatching egg, step（4）Described in nest of laying eggs environment should it is clean, dry,
Dim light and secluded.
It is an advantage of the invention that：The present invention adjusts phosphorus by opening the antenatal content for improving calcium, manganese, zinc in daily ration from breeder
Content ensure that the nutrient needed for breeder is all up to standard, increase the hardness of laid eggs shell, vitamin D promote calcium, phosphorus suction
Receive, improve kind of an Egg Quality, improve quality, control the environment of hen house, improve the looking for food property of breeder, reducing various stress factors causes
Breeder gets a fright, and ensure that the qualification rate of hatching egg, carries out the preventing and treating of disease in practice, improves the laying rate of hatching egg and qualified
Rate, and laid eggs under good chicken coop environment, hatching egg need not clean and secondary sterilization, reduces the breakage rate of hatching egg, the present invention
Collect from environment of chicken house, chicken coop environment, chicken feed, prevention from suffering from the diseases, hatching egg and eliminate advanced age breeder etc. and set about, ensure breeder
Laying rate, the hardness and thickness of hatching egg eggshell are improved, ensure hatchable egg rate and incubation rate, improve the economic effect of kind of chicken house
Benefit.
