First, the advantages of greenhouse chicken
Greenhouse chickens have low costs. The plastic shed for chickens is mainly covered with a layer of plastic film on the outside of the bamboo. A layer of straw is added to the plastic film on the roof to regulate the temperature inside the shed, and then the wire is pulled again. The facilities in the shed are also very simple. In general, as long as more than 2000 yuan, a plastic greenhouse can only be used for 3 years. However, to build a standardized chicken house, generally a group of 4,000 to 5,000 chickens are needed, and the cost of the chicken house is generally around 40,000 yuan. Compared with the two, greenhouses are much cheaper than standardized chicken houses. This is also the main reason why greenhouse chickens are welcomed by local farmers.
Second, the drawbacks of greenhouse chicken
1. High density, slow chicken growth
The number of chickens in greenhouses is generally controlled at about 2,000 to 3,000 broilers. If it is more than 5,000, the density is high. In the greenhouse feeding area, the spacing, size and ventilation of the greenhouse should be reasonably distributed. The spacing between the greenhouses should be 3 to 5 times the span. However, in reality, most greenhouses are a shed, a shed, and some are connected.
2. Poor health and epidemic prevention, high incidence
In greenhouses, chickens are raised on the ground, and Lazard eats and drinks in the shed. It is easy to pick up pathogens, and the chickens have to be given medication every time they fall sick. This will not only increase the cost, but also cause chickens to have large drug residues and affect the health of consumers. In particular, some chicken farmers do not have the concept of health and epidemic prevention. Farmers smash each other, look at each other chickens, do not sterilize, do not change clothes, and the incidence of a chicken causes several chickens to develop at the same time.
3. Poor greenhouse environment
The ammonia concentration is high and the chickens are susceptible to diseases. The coal sheds in the greenhouses are heated and the safety is poor, which can easily lead to gas poisoning. If the greenhouses are poor in drainage facilities, if they encounter rain, the rainwater will flow into the sheds and cause the chickens to crush and die. Because of the large humidity in the greenhouses and poor sanitary conditions, the broilers will be of poor quality and difficult to sell.
Third, the greenhouse precautions
When building a greenhouse, we cannot pursue low cost blindly. With limited funds, chicken farmers must pay attention to reasonable planning and scientific breeding:
1. Reasonable layout
The number of chickens in a greenhouse must be controlled between 3,000 and 4,000, and the shed spacing should be more than 3 times the span, and the length should not exceed 60 meters.
2. Improve feeding mode
Feeding as much as possible on the web; as far as possible to achieve all-in and all-out, it is absolutely not allowed to feed chickens of different ages in a greenhouse.
3. Science and disease prevention
The chicken-raising households must have a concept of epidemic prevention, should conduct daily disinfection, and must have certain isolation measures. The surrounding environment and open space of the chicken house should be limed and sprayed inside and outside the greenhouse. In the first two weeks after the chicken is on the market, it is necessary to stop feeding antibiotics and control the drug residue within a certain range.
4. Greenhouse facilities should be improved
The ground floor of the greenhouse should be made of concrete floor, and each batch of chickens should be cleaned after slaughter. Bricks are used to construct pillars. Asbestos roof tiles and grass curtains are used as roof materials. The environment of chicken coops is better, and the survival rate of chickens will be higher.
