1. Construction of a chicken farm
Non-pollution Wuji Farm should be scientifically sited, away from traffic trunks and residential areas, there is no industrial pollution within 3 to 5 kilometers around, Digging the epidemic prevention ditch outside the court, disinfection pool at the entrance, chicken houses, roads and equipment are often disinfected. The house is well lit, fresh air, and reasonable breeding density to prevent harmful animals from attacking. There are no harmful substances in the foundation, wood and paint.
2. Feed and feed additives
Select feed ingredients that meet pollution-free standards, avoid the use of corn, soy, soybean meal and other feeds that have exceeded pesticide levels, and do not use moldy, worm-eaten, agglomerated, and odor-rich feeds. Appropriate amount of vegetables, grains, etc.
Strictly abide by the relevant provisions of approved feed additives, select suitable feed additives, and prohibit the use of flavoring agents, synthetic colorants, synthetic antioxidants, and chemically synthesized preservatives, non-protein nitrogen, and some binders. Additive products should obtain product production licenses and product approval numbers. In addition, various feed and feed additives should comply with the label's usage and dosage. Industrial by-products should not be used as feed ingredients. It is forbidden to use genetically modified feeds and feed additives.
3, feeding and management
3.1 Nutrition
Supply full price with pellets. At the same time, strengthen management, create a suitable growth environment for chickens, reduce stress factors such as catching chickens, transfer, noise, refueling, water cutoff, immunity, and invasion of animal diseases, and do a good job in environmental sanitation and strengthen prevention and disease prevention. Feeding is stopped 8 to 12 hours before slaughter and water supply continues.
Before brooding, the brooding shed must be rinsed clean and strictly sterilized. Disinfecting pool should be set in the brooding house entrance and exit. The walls should be brushed white with 10% lime water. The floor should be cleaned and rinsed, then sprayed with 3% caustic soda water once, and then used. Maring solution fumigation 1 disinfection. The method is to close the brooding house, using 28 ml of formalin and 14 g of potassium permanganate per cubic meter of space and fumigate for more than 12 hours. In addition, the brooding utensils are cleaned and disinfected and placed in a brooding house for disinfection at the same time. After the brooding house is sterilized, it will be left empty for 2 weeks. During this period, it is forbidden for personnel and objects to enter or leave. The surrounding environment is disinfected with 2% to 3% pyrogenic alkali solution or 3% "Korrillin solution" (the main component is crude soap, resin, and a little sodium hydroxide).
3.2 Temperature
At room temperature between 20 and 26°C, the first week of the brooder was controlled at a temperature of 33 to 35°C, and then reduced by 1 to 2°C per week thereafter, and maintained at 18 to 20°C during the 8th week. During the brooding process, the temperature should be adjusted flexibly according to the performance and status of the chicks, and the temperature can be defrosted after 8 weeks of age.
3.3 Humidity
Before brooding 10 days old, the humidity in the brooding house should be maintained at about 63%. Humidity is too low to increase the humidity by placing evaporating water trays on coal stoves in brooding houses. After 10 days of brooding, the amount of respiration and excretion of chicks increased, and the broilers began to become wet. Attention should be paid to proper ventilation, timely removal of feces, and replacement of litter, in order to reduce the humidity inside the house.
3.4 Density
The chick rearing density is closely related to the normal development and health of the chicks. The density is too large, which affects the movement; crowded chickens, unequal intake of drinking water, etc.; the density is too small, resulting in low utilization of equipment, waste of manpower and material resources, and high feeding costs.
Feeding and management should adopt all-in, all-out systems, and separate male and female breeding. No more than 300 per group, density no higher than 8 per square meter.
4, disease prevention
In hatchery chicks, subcutaneous injections of Marek's vaccine (0.2 ml) were given on the first day. From 1 to 15 days of age, 0.2% furazolid was added to the diet to prevent the disease. 7 to 10 days of age can be diluted with 10 times of the II-type vaccine intranasally immunized, can also be immunized with water to prevent chicken Newcastle disease, and can be inoculated chickenpox vaccine. Chicks are dosed once every 35 to 37 days, every 3 to 5 days, to prevent Salmonella, Escherichia coli and other diseases, the preferred drug is enrofloxacin, drinking water at a dose of 10 mg/kg, and often using 10% of “poisonous†1:600 ​​water disinfection. Care should be taken to prevent coccidiosis in the first 3 weeks. About two weeks later, the first chicken bursal vaccine was exempted, and the immunizations were boosted again 2 weeks later.
