The management method includes illumination management and feeding management, and feeding management includes a feeding method and feed additive management. Compared with the prior art, the management method has advantages that light increase is performed on the broiler breeder hens and regulated repeatedly, a feed addition rate is increased, decreased and increased again sequentially, proper feed additives are added at corresponding stages, and consequently development conditions of the hens are enhanced, energy accumulation is promoted, egg yield and double-yolk egg laying rate of the broiler breeder hens are increased, healthiness and egg laying persistence of the hens are kept, qualified hatching egg yield is guaranteed, and economic benefits are increased for farmers.
Description
Technical field
The invention belongs to technical field of agricultural breeding, be specifically related to a kind of manager improving Breeder hens double-yolked egg productivity
Method.
Background technology
Double-yolked egg nutrition is enriched than common egg, wherein lecithin, aminoacid and free-fat acid ratio common chicken egg many ten
Several times, but owing to managerial experiences are not enough, the yield of double-yolked egg is relatively low, and feed management and illumination management in each stage affect
Laying rate and the yield of double-yolked egg, prior art is when kind of a laying rate of chicken reaches 5%, and pubis spacing reaches two fingers, and chest muscle is grown
There is certain deficiency with energy accumulation, if increasing kind of a probability for chicken product double-yolked egg by improving feed ingredient, easily causing kind
Chicken is uncomfortable, causes egg production to decline, affects the rate of fertilization behind peak period and laying rate.
Summary of the invention
It is an object of the invention to for existing problem, it is provided that a kind of manager improving Breeder hens double-yolked egg productivity
Method.
The present invention is achieved by the following technical solutions: a kind of management method improving Breeder hens double-yolked egg productivity, bag
Including illumination management and feeding management, wherein feeding management includes the management of feeding method and feed additive, and particular content is as follows:

Light application time is 12 hours；When Breeder hens 21 week old, intensity of illumination is 70-80lx, and light application time is 12 hours；At Breeder hens
During 22 week old, intensity of illumination is 60-70lx, and light application time is 13 hours；When Breeder hens 23-24 week old, intensity of illumination is 70-
80lx, light application time is 14 hours；The laying period started from Breeder hens 25 week old, every ten days be a cycle, and each cycle divides
For three phases, the first stage is 3 days, and intensity of illumination is 60-70lx, and light application time is 17 hours, and second stage is 4 days, light
Being 90-110lx according to intensity, light application time is 14 hours, and the first stage is 3 days, and intensity of illumination is 70-90lx, and light application time is
15.5 hours；
(2) feeding method management: from starting illumination management to during seeing egg, week feeding capacity improve 5-8%, when seeing egg, feeding capacity
Only reach 134g/；In time seeing egg to day laying rate be 30% time, day laying rate often improve 5%, then feeding capacity increases 2.5g；From day
When laying rate is 35% to day laying rate be 60% time, day laying rate often improve 5%, then feeding capacity increases 2g；From day laying rate it is
To egg-laying peak when 65%, day laying rate often improve 5%, then feeding capacity increases 3g；
(3) feed additive management: from starting illumination management to during seeing egg, adds the feed additive of 3% in day feedstuff；
In time seeing egg to day laying rate be 30% time, day feedstuff adds the feed additive of 4%；To day when laying rate is 35% day
When laying rate is 60%, day feedstuff adds the feed additive of 2%；To egg-laying peak when laying rate is 65% day, in day
Feedstuff adds the feed additive of 3%.
Further describing as to such scheme, described feed additive manages for female Breeder hens, can improve
The feed intake of female Breeder hens and feedstuff absorbance, and then make female Breeder hens be rapidly achieved sexual maturity, keep the most healthy
State, when day, laying rate reached 5%, pubis spacing reaches two fingers partly to three fingers, keeps chicken group healthy and lays eggs persistently, simultaneously
Feed additive can also blood circulation promoting and the conversion of feed nutrition, improve produce double-yolked egg probability.
Further describing as to such scheme, described feed additive is made up of the raw material of following weight portion: Fructus Cucurbitae moschatae
Powder 25-30 part, Maoyanmei tea 25-30 part, soybean protein powder 10-15 part, vitamin C 4-6 part, vitamin D 4-6 part, dimension is raw
Element E 4-6 part, motherwort powder 4-6 part, Rhizoma Atractylodis Macrocephalae powder 4-5 part, Endoconcha Sepiae powder 2-3 part.
Further describing as to such scheme, the preparation method of described feed additive comprises the following steps:
(1) Maoyanmei tea being added suitable quantity of water to soak 5 hours, slow fire heats 30-40 minute, filters, obtains filtering residue and filtrate is standby
With；
(2) grind after above-mentioned filtering residue being dried and obtain dried bean curd powder, with Fructus Cucurbitae moschatae powder, soybean protein powder, motherwort powder, Rhizoma Atractylodis Macrocephalae powder and sea
Egg capsule of a mantis powder is puddled and is uniformly obtained mixed powder；
(3) above-mentioned mixed powder is gradually added in whipping process filtrate in step (1), after stirring, sealing and fermenting 2-3
My god, dry, pulverize, obtain fermented product；
(4) fermented product is puddled uniformly with vitamin C, vitamin D and vitamin E, obtain feed additive.
Maoyanmei tea contains natural plants frost and flavone, can not only improve body digestion, absorption and resolution to feedstuff
Power, moreover it is possible to promote internal ferment function, active cell and promote various protein synthesis, activating immune cell, strengthen new old generation
Thank.
In the present invention, method for breeding is applicable to the use of big-and-middle-sized plant, the beneficially statistics in chicken farm, small-sized plant
Can be by compared with the situation of laying eggs of big chicken farm laying rate, the management making correspondence adjusts.
The present invention has the advantage that compared to existing technology and Breeder hens adds light in advance, and repeatedly regulates, and cooperation is raised
Expect the adding rate accelerated again from fast to slow, and increase suitable feed additive in the corresponding stage, strengthen chicken mass-sending and educate shape
Condition, promotes the accumulation of energy, improves laying rate and the productivity of double-yolked egg of Breeder hens, and keeps the health of chicken group and lay eggs persistently
Property, and then ensure the yield of qualified hatching egg, improve the economic well-being of workers and staff of raiser.
