1, applicable object: ① Suitable for medium and large-scale and high-density chicken farms. It is suitable for aquaculture enterprises that have been seriously complained about or dealt with the odor, flies and emission problems caused by aquaculture.
2. Construction cost: the shed ring adopts the construction method of cement column+wooden frame+asbestos tile+curtain cloth, and the cost per square meter is about 100 yuan, plus the track and partition net under it and the supporting electric harrow turning machine, it will cost about 100 yuan. In 200 yuan, the larger the site area, the lower the average cost. The cost data is for reference only.
3. Introduction of key components: The electric padding harrow machine with fixed guide rail above the padding layer can rake the chicken manure leaked from the padding net into the padding, and the chicken manure can fully contact with the microbial complex bacteria in the padding, so that the chicken manure can be rapidly decomposed by the microbial complex bacteria in the padding.
4. Supporting facilities and products: ①. Bacteria: compound bacteria in dynamic fermentation bed are used, with an area of about 3 yuan per square meter, and about 0.5 yuan is added every year; ② Cushion: The price of sawdust in Nanning is 50 yuan /m3, which can be used for more than 3 years once laid, and needs to be replenished 3-4 times a year, totaling about 20 cm; ③ Using automatic feeding trough; (4) Use Plasson-style drinking machine; ⑤.A993 electric harrow chicken belt pad: 1 10,000 yuan, parameter: length 4 meters, calculated by adding 800 yuan for each extension 1 meter, single-phase motor power is 2.2KW, three-phase motor power 1.5KW, harrow depth is about 20 cm, and harrow speed is 7 ~ 10 meter. ⑥ Others: spray device, mainly used for automatic spray cooling, water supplement and bacteria supplement.
5. The advantages of this technology are: ① ammonia gas is eliminated, the site is kept dry, mosquitoes and flies rarely breed, chickens are protected by probiotics, diseases are greatly reduced, the traditional appearance of chicken farms is changed, and the breeding and social benefits are outstanding; ② It can be raised in high density. Especially in the original fast-growing chicken breeding mode, it can be realized with only a little change; (3) Because the feeding of bacteria into the fermentation bed and the harrowing of the padding are mechanized, and the microbial compound bacteria are used to degrade chicken manure, the ground, chicken coop and ammonia gas generated by chicken manure treatment will not be washed frequently in the chicken coop. Can save manpower, material resources and financial resources, greatly improve the breeding efficiency and improve the breeding environment; 4. Taking care of the welfare of chickens is also an important guarantee for the physical and mental health of breeders.
6. Disadvantages of adopting this technology: ① There is no chicken manure to sell; ② The price is slightly higher. Small and medium-sized retail investors are hard to accept. 7. Note: 1. In this process, an automatic stuffing harrow machine with a fixed track is installed above the stuffing layer, which can harrow the chicken manure falling on the stuffing into the stuffing, and the chicken manure fully contacts with the microbial complex bacteria in the stuffing, so that the chicken manure is completely degraded by the microbial complex bacteria in the stuffing.
Second, because the feeding of bacteria in the fermentation bed and the harrow of the padding are mechanized, the microbial compound bacteria are used to degrade chicken manure, and the floor, chicken coop and ammonia gas generated by chicken manure treatment will not be washed frequently in the chicken coop. It can save manpower, material resources and financial resources, greatly improve the breeding efficiency and improve the breeding environment. 3. Measures such as immunization, deinsectization and disinfection can be carried out normally. 8. Construction technology of reticulated broiler fermentation bed;
The zero-emission breeding enclosure of broiler net consists of a greenhouse enclosure, a net laid on a shelf, a padding fermentor for decomposing feces, an electric harrowing machine for supporting padding and a track for supporting parts of the electric harrowing machine.
I shed-type fenced house
Fence houses should be built in places with good lighting and smooth air. In order to facilitate management, they are generally built in long strips, which is conducive to the display of chicken pens. Structurally, the mode of cement column+wooden frame+asbestos tile+roller blind is adopted in the south, and the steel frame structure or cement column plus brick structure is adopted in the north, which is simple and low in cost. Windproof, warm, daylighting and ventilation window are set on both sides of the pen house, and water curtains and fans are installed at both ends of the pen house according to local conditions. Unpowered fans can also be installed on the top of the fence.
Second, the buffer pool
Cushion pool is used to place fermented mattress materials, and the specific width and length are determined by the area of the grid used. That is, a filling pool is set under the grid. The depth is 40 cm, and sawdust with a depth of 20-30 cm can be used as padding. At the edge of the pool, a square steel is buried every 1 m, and the edge is made of bricks. Angle steel is welded at the top of square steel as the track of harrow turning machine. After the track is completed, install the harrow turning machine and debug it.
Third, set up grids, lay plastic nets, install sinks and drinking water lines.
The net rack is directly erected above the fermenter, and the supporting feet are at the edge of the harrow turning machine track or parallel to the square steel for erecting the track, and a row of wood or steel beams are horizontally erected for laying plastic nets for breeding. After the plastic net is installed, the chute is installed around the edge, and then the spraying equipment and drinking water equipment can be installed. Special drinking water equipment is recommended for fermentation bed culture. Agricultural company's water-saving automatic water dispenser for chickens is specially designed for laying hens' fermentation bed culture. Every time a chicken drinks water, it will not spill, drip or waste.
Fourthly, make the gasket.
After all the net racks are installed, sawdust can be put into the fermentation tank, sprinkled with special compound bacteria and corn flour for fermentation padding, and watered to make fermentation padding.
