The current research in the field of production and environmental control mainly focuses on: chicken farm planning layout and biosafety engineering epidemic prevention, optimization of thermal insulation performance of chicken houses in different climate zones, temperature field and airflow field simulation and testing of different types of chicken houses, and cold Heat stress environment regulation, new breeding mode and supporting equipment research and development, field emission reduction and environmental purification, and standardized research and demonstration of breeding support technology. The main progress is as follows:
In the planning and layout of the chicken farm and the bio-safety engineering epidemic prevention, the whole process of full-input and full-out is now formed, or at least the partition layout is implemented by the district, and the whole area can be completely disinfected, which can effectively eliminate the inter-batch pathogens. Ways of dissemination to improve the level of biosecurity. Breaking through the misunderstanding of the site selection of the chicken farm, the feng shui consciousness of the site selection, combined with the one-way ventilation and the field purification technology of the dominant wind direction. For the personnel entering and leaving the area, the disinfection of vehicles and the disinfection of air and drinking water in the chicken house, the world has created the high-efficiency and safe disinfection technology and equipment for high-concentration micro-acidic electrolyzed water, providing environmental protection for the epidemic disinfection of farms. Efficient and safe low-cost disinfection measures.
In the standardization research of chicken house construction, the focus is on the air tightness requirements of the house ventilation in the closed house, and the temperature variation characteristics of the different climate zones. The research proposes suitable feeding methods, feeding density and enclosure. Structural economic thermal resistance requirements. In view of the climatic characteristics of the arid and windy sand areas in the northwest, the construction style of the side wall corridors of the wind-falling houses with optimized sandfall and anti-summer wet curtain cooling temperature drop is optimized.
In the area of emission reduction and environmental purification, the system mainly promotes the belt cleaning technology. After the original scraping and cleaning the manure into the conveyor belt, the concentration of harmful gases in the house can be reduced by more than 50%, correspondingly reducing the amount of winter ventilation and Energy saving is about 50%, and the CO2 concentration control standard in the house is increased from 2500mg/m3 to 5000mg/m3 without affecting air quality and production performance. In terms of the treatment of the exhaust air and the prevention of cross-propagation between the houses, the actual test proves the danger of installing the winter exhaust fan on the longitudinal wall of the chicken house. It is proposed that the exhaust fan needs to be installed on the mountain wall at one end of the chicken house in the downwind direction of the field. This is very beneficial for field purification and bio-safety, especially for chicken farms that cannot do the whole field/zone. It is a key technical point.
In the aspect of new breeding mode and supporting equipment research and development, in view of the process and parameter optimization problems related to the technology and equipment of egg breeders in recent years, the method of setting egg nests in cages can effectively reduce cockroaches. Anal behavior occurs and reduces the fear stress response of the birds and the corticosterone content in the blood. The claw pad provided in the cage can significantly reduce the length and sharpness of the middle toe of the cock and the hen, and has obvious effects on improving the quality of the feathers of the chicken, improving the welfare of the chicken and the level of healthy breeding. In the integration research and demonstration of standardized culture support technology for laying hens, respectively, in the system Daqing Comprehensive Experimental Station (Northeast Region), System 邯郸 Comprehensive Experimental Station (North China), System Huizhou Comprehensive Experimental Station (South China), System Mianyang Comprehensive Experimental Station (Southwest Region) and Chengdu Zhengxin Agriculture and other enterprises have carried out integrated research, forming 4 sets of integrated breeding support technology for laying hens in different climate zones in China.
