Abstract
The invention discloses a breeding method of a laying hen in a brooding period. The breeding method includes water inducing, feeding, density, humidity, temperature, illumination, feed and the like of the laying hen in the brooding period. By means of many-year practice, laying chicks are bred through the technology, development of internal organs and immune organs of the laying chicks is remarkably superior to that of the prior art, and body weights and shin bones of the laying chicks bred for 35 days and 70 days meet standards. After brooding, uniformity of the laying hen is higher than 85%.
Description
Technical field
The present invention relates to a kind of laying hens in brooding period method for breeding.
Background technology
The breeding layer chicken phase is long, general 550-700 days, wherein 450-600 days laying period, and 450 day laying period and 600 days lay eggs
Phase is very big on breeding layer chicken impact, studies for a long period of time discovery through us, laying hens in brooding period cultural method, the length to laying period
There is vital effect.At present, laying hens in brooding method for breeding is uneven, lead to 35 days body weight of chickling not up to standard, 70 days
Shin length is not up to standard, and the uniformity is poor, has a strong impact on production performance and the culture benefit in laying hen all one's life, for this reason, research and development one hatching egg
Chicken brood time (0-84 age in days) method for breeding is imperative.
Content of the invention
The present invention be overcome above-mentioned the deficiencies in the prior art, provide a kind of laying hens in brooding period lure water, material feeding, density, humidity,
Temperature, illumination, feedstuff complete set method for breeding, the present invention adopts following technical proposals to realize:
A kind of laying hens in brooding period method for breeding, including following aspect:
(1) chickling lures water method: referred to as just drink for the first time by drinking-water for 0 Japanese instar chickling, using the method for artificial induction, specifically side
Method step is: drinking-water of 1) first the chicken of 3-5% manually being demonstrated, and other chicken groups are caught up with toward water fountain periphery；2) and then choose
The chicken not drunk water individually carries out artificial induction, accomplishes successfully to lure water to chickling 100%.
The formula of chickling water before 5 ages in days: this formula is made up of following raw material: the qualified water of 18-21 DEG C of sanitary index, often
Add 3 parts of astragalus polysaccharidess, 5 parts of white vinegar, 2 parts of opening medicine, 5 parts of water-soluble multidimensional in 1000 weight portion water.
Guarantee that chickling drinks refrigerant, cleaning drinking-water in brood time, using following methods: change water 4-6 when using water pond daily
Secondary；In waterline end with, after stopper blocking, insertion tube for transfusion controls running water.
(2) chickling material feeding method:
Material feeding after 5-6 hour after luring water to chickling, feeds Semen setariae or the corn grit that water is mixed；So that activation chickling intestinal enzyme
System's activity.
1 age in days starts to feed complete feedstuff nutrient fodder one.To total feed intake 180-210 gram of every chickling of 15 age in days；To 15 days
Age body weight is less than the chicken group of 100g or summer broods and continues feeding complete feedstuff nutrient fodder one to 35 age in days, and every chickling always searches for food
650 grams of amount.
Feedstuff is sprinkling upon on the shield of white, shield is 2 pieces of cottons, accomplishes that feeding duty less adds, and a few days ago must not place material
Disk, using artificial spreading, eats and how much spreads how many, accomplishes that feed intake maximizes.
(3) brood time density implementation:
0-5 age in days meet cage be less than 50 chickens/square metre；Flat support, net support less than 30 40 chickens/square metre；
Meet nipple drinking device and water pond double water, double water refers to that nipple drinking device and water pond use simultaneously simultaneously, and nipple drinking-water
Device be no less than 15 chickens/；Meet water pond and be no less than 2 centimetre/chickens；Meet charging tray and be no less than 2.5 centimetre/chickens.
57 ages in days carry out for the first time point group with reference to immune programme for children, at least separate in cage behind the 1/3 of chicken total quantity, and point group
Charging tray, water pond number keep constant it is impossible to drop off disk, water pond in for the first time immunity recession.12 15 ages in days combine immune journey
Second point of group of sequence, separates the 1/3 of chicken total quantity, and in cage, water pond, charging tray number are still constant, and will 4-5 days gradually after disconnected beak
Remove；For the chickling being completely dependent on water pond, charging tray after 12-15 age in days divides group, keep searching for food position no less than 4 centimetres/
Chicken, drinking-water position is no less than 4 centimetre/chickens.For fully relying on nipple drinking device, less than 5 chickens/.
(4) young phase humidity implementation:
Chickling 0-84 age in days humidity requirement: 65 75%.Pay high attention to the humidity that chickling is born in latter 3 days, humidity can not
Less than 65%, daily repeatedly to metope, ground water spray.
(5) brood time temperature implementation:
In brood time, the temperature setting in winter for the hen house is 35-37 DEG C, in 33-35 DEG C of summer, drops 0.5 DEG C daily after 2 days,
Till dropping to 24 DEG C.Night arranges high 1-2 DEG C than day temperature.The height that the suspension height of thermometer is carried on the back with chicken is as standard；Right
Being carried on the back by intermediate cage chicken of staged cage is highly defined.
(6) brood time illumination implementation:
The light application time of the semi-open hen house of standard is: is within 1-3 days illumination in 24 hours；It is within 4-35 days illumination in 23 hours；35 days
Reduce illumination in 2 hours afterwards daily；Natural lighting is adopted after 40 days.
The intensity of illumination of the semi-open hen house of standard is: it is 5w/m that young bird educates 1-3 days phase intensity of illumination2, intensity of illumination is within 4-7 days
3w/m2；The intensity of illumination of 8-11 days is 2w/m2；Intensity of illumination after 12 days is 1.25w/m2.
The window daylighting gross area is 1:7～9 with the ratio of hen house area.For window areas more than 3m2Attention shading,
Window areas are less than 2m2Hen house notes the light filling after 40 days, and daily light application time is not less than 9.5-10 hour, intensity of illumination
2.7w/m2Left and right；For closed hen house from 40 days, daily light application time is 9.5-10 hour, intensity 2.7w/m2Left and right,
Light is added after body weight is up to standard；Body weight requirement up to standard: 3.2 jin of brown shell layer body weight, powder housing weighs 3.0 jin.
(7) brood time feed formula:
1-15 age in days, complete feedstuff nutrient fodder one, wherein meet following nutritive index: the mass fraction 20% of protein,
Energy 2900 kilocalories/kg, the mass fraction 0.45% of Methionine, the mass fraction 0.9% of lysine, the mass fraction of calcium
0.9%, the mass fraction 0.45% of phosphorus, the mass fraction 0.3% of salinity.
16-35 age in days, complete feedstuff nutrient fodder two, wherein meet following nutritive index: the mass fraction of protein
18.5%, energy 2900 kilocalories/kg, the mass fraction 0.45% of Methionine, the mass fraction 0.9% of lysine, the quality of calcium
