The first object of the present invention is to provide a kind of method for improving egg-laying bird laying rate.To realize the purpose, this hair
It is bright to provide following technical scheme：
A kind of method for improving egg-laying bird laying rate is specific to be：Melatonin implant is subcutaneous in the neck of egg-laying bird.
The applicable egg-laying bird of the method for the invention includes chicken, duck, goose, dove, quail, wild goose, peacock etc., preferably egg fowl
Class is lay eggs laying hen or breeder, most preferably laying hen.
To reach the purpose for the laying rate for improving laying hen full laying period, the heeling-in time of epiphysin of the present invention is egg
Before the age in days of chicken 300 is laid eggs to stopping.
Behind 180 days peaks of laying eggs of laying hen, the epiphysin in chicken body declines quickly, and internal free oxygen increases, through numerous studies
Experiment finds that 300 age in days laying hens, the free oxygen of body increases, especially ovary, causes ovarian function to decline, and laying rate declines.This
When suitably increase a small amount of Exogenous Melatonin, equivalent to illumination is not influenceed, remove free oxygen, promote follicular development, excite ovum
Nest function, increase laying rate.External source epiphysin can not be more, and amount is too big, on the contrary equivalent to illumination is reduced, reduce laying rate.
Method of the present invention, preferably epiphysin provide in the form of silica gel is coated with epiphysin particle.The silica gel bag

Epiphysin is a kind of hormone mainly secreted by pineal body, and chemical constitution is N-acetyl-5-hydroxytryptamine.Epiphysin
An important function be by retina-pineal body axle by periodicity of illumination control biological rhythm.During breeding layer chicken often
Promote laying hen to open production ahead of time using illumination is extended and improve laying rate, be to pass through reduction during thisEndogenousEpiphysin comes
Work, especially laying eggs early stage and egg-laying peak is such.
But after egg-laying peak, laying hen ovarian follicle aging causes reproductive capability to decline.Immunologic function, which declines, also results in laying hen
Laying rate declines.Ovarian follicle metabolism in ovulation period is very vigorous, and this process can produce substantial amounts of free radical, free radical
DNA Damage can be caused, causes apoptosis of granulosa cell, as long as the apoptosis of granulosa cell for having 10% in 1 ovarian follicle may result in
Follicle atresia.The present invention is had found by the laying hen behind peak of laying eggs and other egg-laying birds, in due course by research experiment
Between it is subcutaneous in neckIt is exogenousThe epiphysin of heeling-in appropriate amount, the laying rate of egg-laying bird, research experiment knot can be increased on the contrary
Fruit is satisfactory.

As a result show：The egg production of control group is set to 0, relative quantity of more each experimental group compared with control group, 470 days
Age laying hen, the laying rate of laying hen of tri- heeling-in groups of 10mg, 20mg, 30mg and daily total egg size have extremely notable compared with control group
Improve.
In summary, 300 age in days laying hen, the laying rate of laying hen of heeling-in 7.5~15mg groups and daily total egg size and control group
Compared to being significantly increased；360 age in days laying hens, the laying rate of laying hen of heeling-in 15~30mg groups are significantly increased compared with control group；
470 age in days laying hens, the laying rate of laying hen of heeling-in 10~30mg groups and daily total egg size are significantly increased compared with control group.More than
As a result illustrate, the present invention, to the epiphysin for stopping 7.5~30mg of laying hen heeling-in before laying eggs, can significantly improve egg to 300 ages in days
Laying rate of chicken and total egg size, generally speaking, as laying hen age in days increases, effective heeling-in dosage of laying rate are improved also with adding
Greatly.
It is described above, only it is the description to the general explanation and specific embodiment of the present invention, is not to the present invention
