Farmers pay attention: do not use asbestos tiles on the top of the chicken farm!

In rural areas, in order to reduce the cost of raising chickens and maintain the ventilation of chicken farms, some farmers will use no-top design and use asbestos tiles to cover rain and dew in the morning and night, which is very disadvantageous. Here, let's find out why asbestos tiles are not used on the tops of chicken farms.

In order to maintain the ventilation of the chicken farm, reduce the disease of the chickens, or to save money, many chicken farmers use the no-top design to block the rain and dew with asbestos tiles when it is dark. In fact, the construction of this kind of chicken farm is seriously unreasonable, because the roof is an important thermal insulation facility of the chicken farm, and the temperature is closely related to the production performance of the chicken. When the temperature in the chicken house was on the high side, the chicken appetite decreased, the feed intake decreased, the metabolic rate decreased, the feed conversion rate decreased, and the production performance decreased; when the temperature in the chicken house was on the low side, the energy needed for maintenance increased and the feed intake increased; feed consumption increased, feed reward decreased, and production performance also decreased. Moreover, in the environment of high temperature or low temperature, the decline of chicken self-immunity leads to an increase in the incidence of epidemic disease, which leads to a substantial increase in the production costs of chicken farms, such as water, electricity, medicine, etc., resulting in an increase in production costs. the disadvantageous situation of profit reduction or even loss. It can be seen that the selection of building materials with good thermal insulation to build the roof is very important to maintain a suitable temperature environment in the chicken house.

The thermal insulation performance of the roof is related to the thermal resistance value and thickness of the building materials used. The greater the thermal resistance value and the thicker the material, the better the thermal insulation performance. Therefore, it is not appropriate for chicken farmers to use asbestos roof. Although the cost of asbestos tile is low, the thermal resistance of this material is only 0.025 square meters h ℃ / 4.184KJ, and the thermal insulation performance is quite poor. In winter, a large amount of heat is emitted from the house, and the temperature in the chicken house is easy to drop and difficult to rise, and the heat preservation difference; in summer, a large amount of solar heat and ground reflection heat permeates, and the temperature in the chicken house is easy to rise and difficult to fall, and the thermal insulation is poor. In this way, a bad microclimate will be formed in the chicken house, which is colder in winter and hotter in summer, and each batch of chickens in production need to invest more people, materials and financial resources to improve the microclimate in the house, which is bound to increase production costs and reduce economic benefits. therefore, the chicken sheds without shed design should not use asbestos tiles to cover the roof.
