Groups suitable for farmers
It is suitable for farmers with 3-5 years of layer breeding experience, a certain economic foundation, strong technology, management ability and market awareness. The recommended breeding scale is 10000-50000.
Basic planning of chicken house construction
Site selection: avoid intensive breeding areas, and the water quality is good. 2. Feeding mode: two-stage cage feeding: brooding and egg laying. 3. It is recommended to use closed chicken houses, four rows and three layers of ladder feeding, cement floors, white cement on walls, automatic drinking water, ventilation, mechanical feeding, fecal cleaning, etc.
Specific construction and equipment selection of large-scale chicken houses (taking 15000 as an example)
Standardized chicken house architectural design

The chicken house is 92.54 meters long, of which the front aisle (including the nose) is 3.5 meters, the rear aisle (including the tail) is 2.5 meters, and the single row cage is 85.8 meters long; 44 groups of cages, with a single cage length of 1.95M (including cage frame); The chicken house is 12.22 meters wide, of which the dung ditch is 1.57 meters wide, the middle three aisles are 1.1 meters wide, and the aisles on both sides are 0.95 meters wide; The eaves of the chicken house are 2.6 meters high and the ridge is 1 meter high; An operation room is set at the front side of the chicken house, which is 3.5m wide and 4.5m long
Standardized chicken house Civil Engineering 1. Below the frozen soil layer of the foundation, the foundation is 1.2 meters deep (North), with drilling and bottoming, concrete cushion, concrete C15, foundation masonry mortar M7.5, foundation brickwork from 50 cm wide to 37 walls in two steps, and the internal and external height difference of the chicken house is 0.3 meters. 2. Wall thickness (including wall thickness and wall height): wall thickness in southern China is 24; In northern areas, 37 or 24 walls plus 10 cm thick insulation layer, brick concrete structure, masonry mortar M5. Wall height: 2.6m, 1-1.5m higher than the upper chicken coop. A tie bar 2 is set along the wall every 50cm high Φ 6。 Structural column 400 × 360, concrete C25, reinforcement 6 Φ twelve Φ [email protected] The structural column takes root at the concrete base plate. A concrete ring beam is set at 2.35m of the wall, with 5 reinforcements Φ twelve Φ [email protected] 。 Lintel is set for door and window. The concrete column of ring beam lintel is C25. 3. Roof structure the roof adopts double-layer color steel plate, with 10cm thick polystyrene (unit weight above 14kg) insulation layer sandwiched in the middle. The span of the girder is 11.96 meters, the ridge height is 1 meter, the spacing of each girder is 4.49 meters, the upper chord of the girder is 20 I-steel, and the middle is 20 cm × Two sides of the I-beam are butt welded with a steel plate of 20cm thick and 1cm thick. The lower chord is a reinforcement with a diameter of 1.8 cm, which is connected with flower basket bolts in the middle, and the purlin is 100C steel
The site selection and layout should be reasonable
Health and epidemic prevention should be considered from the beginning of the construction of the site. The site should be located in a high terrain with convenient power and water supply and transportation, but it should be far away from roads, railways, downtown, markets and living areas, especially from other livestock farms and slaughterhouses. The layout of feed warehouse, living and office areas, production areas and other areas is reasonable. Production areas and living areas should have a buffer and epidemic prevention isolation zone of 200 meters as far as possible. It is also necessary to establish functional units or communities that can be blocked and isolated so that emergency treatment can be carried out in case of an epidemic. Scientific building structure and construction: building construction should be relatively airtight to prevent birds, beasts and mice from entering the building and spreading diseases. It should also ensure that the temperature, humidity, ventilation, lighting and other conditions and facilities required by chickens of different ages can be provided, and the room spacing should be more than 15 meters.
Affected by the international financial storm, many domestic enterprises have reduced staff or stopped production, which has increased the number of migrant workers returning home. Many migrant workers have been working outside for many years and have accumulated certain funds. They want to use local resources to start their own businesses. The author believes that it is a good way for migrant workers to build small chicken farms at home and achieve entrepreneurship and employment at home. In order to make them avoid detours as much as possible in the construction process and use less investment to give full play to large benefits。
First, we should reasonably choose the site, and do not build blindly. Try to build chicken farms in places with high terrain, leeward and sunny, flat or slightly sloping ground below 2 meters of underground water level, sandy soil, good ventilation, sufficient water and electricity, and convenient transportation; Do not build it in a low, damp and poorly ventilated place. Away from schools, villages, market towns and other densely populated places; Do not build chicken farms in scenic spots, water sources and places expressly prohibited.
Second, we should make rational use of funds and not be greedy for perfection. At the beginning of the construction of farms, many people considered building feed farms, brood farms and other auxiliary facilities, thinking that it would be safer to use their own feed and brood chicks. In fact, when the farms were just built, the funds of ordinary people were not very sufficient. If these farms were built, it would inevitably cost a lot of working capital, which would reduce and occupy the funds for the construction of chicken farms. At present, the formula feed produced by some large feed farms is nutritious, safe and reliable in quality, which is better than the small feed farms built by themselves in any way, and it does not need feed raw material funds, and it can order as much feed as it needs; In addition, some large-scale chicken farms and chicken breeding cooperatives have built brooding farms. Because laying hens generally need to be replaced once a year, it is not cost-effective to build their own brooding farms only once a year.
Third, we should comprehensively support breeding, not single breeding. At present, rural forests and ponds are rich in resources. Adopting chicken fish, chicken fruit and other supporting aquaculture can not only effectively use chicken manure, but also increase income.
Fourth, we should pay attention to environmental protection and do not pollute the environment. When building chicken farms, we must also consider the construction of chicken manure treatment facilities, such as septic tanks, biogas digesters, etc., and do not allow chicken manure to be discharged directly.
Fifth, we should do a good job in epidemic prevention and control, and do not cut corners.
