(1) Scientific choice of site
Flat or slightly sunny slopes with high terrain and easy drainage should be chosen. The soil is not contaminated by pathogens of infectious or parasitic diseases, has good air permeability and can keep the site dry. Sufficient water supply and good water quality. The surrounding environment is quiet, far away from the downtown area and heavy industry area, advocate decentralized construction of farms, it is not suitable to engage in intensive community farming. Convenient transportation and sufficient electricity.
The construction of chicken houses can be built flexibly according to the scale of farming, economic strength and other circumstances. Its basic requirements are: roof height of 2.5 meters, the height of the two sides of 2.2 meters, with convection windows, the roof of the sunny side of the external skylight, the chicken coop at both ends of the mountain wall with a large window or door, and the installation of exhaust fans. This design can combine the use of natural ventilation and mechanical ventilation to achieve effective ventilation and reduce costs.
(2) Strict selection of chicks
Introduction of high-quality, high-yield meat and egg breeds, selecting suitable for local growth conditions with high production performance, disease resistance, and can produce high-quality offspring of the breed, purification of the breed, to prevent vertical transmission of epidemics. Strict selection of chicks to ensure that the chicks are robust, disease resistant and have high production potential.
(3) strict medication system
①Environmentally friendly disinfectants, do not use toxic insecticides and toxic sterilization (poison), antiseptic drugs. ② Strengthen the purchase of drugs, additives, distribution and use of supervision and guidance. Strictly enforce the national "Feed and Feed Additives Regulations" and "Regulations on the Administration of Veterinary Drugs", from the regular large-scale standardized manufacturers to purchase drugs and additives to prevent abuse. The distribution and use of drugs should be prescribed by veterinarians and supervised and guided to improve the internal environment and increase resistance. ③ The purchase, distribution and use of veterinary biological products must comply with the national "Measures for the Administration of Veterinary Biological Products". ④Unified planning, rational construction of chicken coops, to ensure that the implementation of disinfection and isolation, unified biosecurity measures and health and epidemic prevention system.
(4) Strengthen biosecurity
Inside and outside the chicken coop, around the field to improve environmental hygiene. The bedding in the house should not be too dirty, too wet, dust should not be too much, utensils should be placed in order, often kill flies inside and outside the house. The field area to eradicate weeds, can not put dead chickens, garbage, etc., to maintain regular good health conditions. There should be caustic soda disinfectant pool at the entrance of the field and chicken coop, and the effective concentration of caustic soda should be maintained frequently, and the disinfectant water should be stepped on the feet when entering and leaving the field or chicken coop, so as to kill the germs brought by the soles of shoes. Feeding management personnel to wear work clothes, chicken farms to limit the outsiders to visit, not to mention the chicken trucks are not allowed to enter.
(5) Standardize feeding management
Strengthen feeding management, improve the microclimate of the house, provide a comfortable production environment, pay attention to the prevention of diseases as well as early detection and treatment, reduce and eliminate the occurrence of avian diseases, and reduce the use of drugs. ①Provide appropriate temperature and humidity according to the characteristics of each weekly chicken. ② Ensure good air quality in the house, do a good job of ventilation management, improve the microclimate in the house, always remember that good ventilation is a prerequisite to ensure good chicken. ③Reasonable light and limited feeding. According to the chicken's biological clock, growth pattern and its morbidity characteristics, scientifically formulate the light program and feeding restriction program, with different nutrients fed to chickens at different stages of growth and development, in order to make the dietary nutrients closer to the nutritional needs of chickens, and can improve the feed conversion rate.
(6) environmentally friendly green production
①Bedding using micro-ecological agents spray treatment, and then weekly treatment, while the weekly sprinkle of sodium bisulfate, in order to change the bedding acidic and alkaline environment, to inhibit the breeding of harmful bacteria, and to improve the resistance of the chicken body. ② rational treatment and use of waste produced in the production, solid manure by harmless treatment into a composite organic fertilizer, sewage must be no less than 6 months of closed system fermentation after application.
(7) the use of green production feed
①Strictly feed raw materials. Requirements for the planting of production bases with excellent ecological environment, water quality is not polluted, away from industrial and mining, the atmosphere is not polluted by chemical plants; acquisition should be strictly tested drug residues, heavy metals and mycotoxins. ② feed formula scientific. Nutritional ratios should take into account the digestibility of various amino acids and phosphorus utilization, and pay attention to the addition of synthetic amino acids in order to reduce the level of feed protein, which meets the needs of poultry, but also reduce nutrient excretion. ③ Pay attention to the management of feed processing, storage and packaging and transportation: pollution is strictly prohibited in the process of packaging and transportation, and it is strictly prohibited to add hormones, antibiotics, veterinary drugs and other additives to the feed, and to strictly control the production process and operating procedures, and to strictly control the nutritional and hygienic quality of the feed, so as to ensure that the production of safe, environmentally friendly green feed. ④Scientific use of pollution-free high-efficiency additives, such as micro-ecological preparations, enzymes, acid preparations, plant-based additives, bioactive peptides and microelements with high utilization rate, to regulate the balance of intestinal flora and improve the digestibility, to promote growth, to improve the quality, to reduce the discharge of waste, in order to reduce the use of veterinary drugs, antibiotics, hormones, to reduce the occurrence of disease.
