Several problems needing attention in chicken house construction

A reasonable layout structure of the chicken house can provide a good living environment for the chicken and make it give full play to its production potential, so it is necessary to plan and build the chicken house reasonably in addition to understanding the physiological characteristics of the chicken itself.

Picture 1, chicken layout notes 1. The site should be located far away from residential areas, convenient transportation and away from the road. The terrain should be high and dry and sunny. Try to keep out the light in winter, the wind in summer, and no water after rain. The area is relatively large, leaving room for development. Water resources are rich and pollution-free, easy to access, and sufficient electricity is guaranteed. The structure of the house is practical and economical, saving both capital and energy, and its orientation is in line with local natural and physiological conditions, good lighting, easy ventilation and easy operation, so that it is beneficial to heat prevention and cooling in summer and heat preservation and cold prevention in winter. The layout of the house should be reasonable, so that the production area and the non-production area should be separated from the non-production area, the non-production area and the water source should be in the upwind direction of the chicken farm, the dirty road and the clean road should be separated and not crossed, the dung farm should be located in the downwind direction of the chicken farm, and the brooding house should be separated from the breeding house. The brooding house is located in the upwind direction of the chicken farm. To understand the epidemic situation of local poultry disease, try to avoid epidemic areas or areas where the epidemic has occurred. 7. Avoid urban pollution areas and take appropriate environmental protection measures to reduce environmental pollution as far as possible. the overall requirements of the chicken house building (1) to meet the needs of broiler breeding (2) leave room for technical transformation to facilitate the expansion of reproduction. Construction, strict saving of funds and energy (4) in line with the requirements of the general layout of the chicken farm (2) the construction types of the chicken house are closed and open, with no windows around the closed chicken coop, using artificial lighting and mechanical ventilation, it is an energy-consuming chicken coop, the microclimate environment is easy to control and easy to manage. The open chicken coop, that is, the windowed chicken coop, is an energy-saving chicken house that makes use of the natural resources of the outside world. Generally, there is no need for power ventilation, full use of artificial lighting. The disadvantage is that it is greatly influenced by the outside world. The design of the house structure is based on both the rational index of the best chicken environment and the economic index of construction cost, which is mainly related to the factors such as ventilation, warmth, cooling, water supply and drainage, daylighting and so on. 3. The purpose of ventilation and ventilation is to eliminate the dirty air in the house as much as possible: introduce fresh air, keep the air fresh, cool down, disperse humidity, and reduce the somatosensory temperature of chickens, which is the first element to measure the environment of the chicken house. (1) parameters: air exchange is calculated according to the maximum requirement in summer, 4-5 cubic meters per kilogram of body weight per hour, and the concentration of harmful gas does not exceed 20ppm of ammonia, l0ppm of hydrogen sulfide and 0.15% of carbon dioxide.
