In winter and spring, the temperature is low, especially when the seasonal changes in temperature, large temperature difference between day and night, to increase the difficulty of raising chickens, which requires the husbandry and management to pay attention to every detail, to ensure the safe growth of chickens.
Ventilation:
More cold insulation
In winter and spring, the climate is cold. It is necessary to ventilate the air and keep the temperature inside.
In winter and spring, if ventilation and ventilation are neglected in order to keep the chicken house warm, the excrement of feces and damp litter from the chickens will not be cleared in time. The ammonia gas in the house will accumulate and the concentration will increase, leading to ammonia poisoning or other diseases in the chicken. . To this end, farmers need to strengthen their husbandry and management work. They can use ammonia-absorbing deodorants to reduce the concentration of ammonia in their chicken houses. Commonly used are ferrous sulfate, superphosphate, copper sulfate, hydrated lime, and the like. Minimize watering during operation to prevent sink leaks. If the humidity inside the house is too large, the house waste and damp litter should be promptly removed. Noon window ventilation. In general, ventilation is started at 6 days of age, and as the age increases, ventilation is increased so that the birds have enough oxygen.
At the same time as ventilation and ventilation, the chicken house requires good cold resistance and meets the requirements for winter and spring insulation. Guard against chilling caused by chilling caused by chilling, prevent severe stress caused by excessive temperature difference. The vents should be more than 1.5 meters above the back of the chicken. Maintain the coop to prevent thieves and drafts from invading the flock. The broiler chickens raised on the plains should be thickened with padding, usually more than 10 cm, and use litter to increase the room temperature.
Disease prevention and control:
With high energy feed
According to the different growth stages of broilers, full-priced diets are prepared according to the feeding standards. Due to the low temperature in winter and spring, the heat consumption of broilers is relatively large. When formulating diets, the standard of metabolic energy in feeds can be appropriately increased, and the proportion of protein in feeds should be properly reduced. At the same time, special attention should be paid to the vitamin content in diets. The raw grain of the formulated feed must be free of mildew and impurities to prevent respiratory diseases.
Do a good job of preventing viral diseases and bacterial diseases, strengthen biosafety measures, and do a good job in vaccination:
1. Chickens should be introduced from healthy breeding farms to prevent the spread of pathogens through vertical transmission.
2. It should create a good breeding environment. Keeping utensils and sterilizers are strictly differentiated and regularly sterilized to prevent horizontal transmission of diseases. At the same time, the occurrence of disease outbreaks in neighboring chicken farms and in the area are regularly monitored and preventive measures are taken.
3. Regularly monitor the health condition of the flocks in this farm and handle the epidemic in time. Adhere to the chicken disinfection, eradication of rodents, to prevent the spread of rodent diseases, diseased and dead chickens buried disposal, the principle of isolation of chickens and healthy chickens.
Coop disinfection:
Master three points
Eliminating dirt There are many kinds of dirt in chicken houses, including feces, dust, feathers, spider webs, filthy bedding, etc. These substances will hinder the contact of disinfecting drugs with bacteria, reduce the effectiveness of disinfection and disinfection, even if disinfection drugs are used repeatedly, disinfection. The effect will not be ideal. Before spraying the disinfectant, the dirt in the house must be removed, including walls, floors, roofs, railings, cages, troughs, sinks, shovels, brooms, etc. The iron should be used to remove solid dirt that has adhered to it, and then rinse with clean water. After drying, spray the disinfectant liquid. In particular, care should be taken to clean out cracks in the walls, the edges of doors and windows, and exhaust nozzles.
A sufficient amount of disinfectant must be prepared at the prescribed concentration and cannot be arbitrarily increased or decreased. Disinfecting objects need to be left for a day or so after they are washed to make them fully dry. If they are not thoroughly dried or sprayed immediately after washing, the residual moisture will dilute the disinfectant solution and will affect drug penetration. The liquid must be able to moisten the object, the amount of liquid sprayed per square meter is 1.5 to 2 liters. If the liquid is not sufficiently flushed before spraying, 3 liters of liquid per square meter is required. Disinfection liquids should be sprayed in order from top to bottom, first to the roof, ceiling, rear wall, fixed facilities, and finally to the ground. Do not miss the sheltered parts.
Proper use of disinfectants at the appropriate time must have sufficient time for action. The characteristics of various disinfectants are different, and the time requirements for their effects are also inconsistent. The chicken house is fumigated with potassium permanganate and formalin and must be fumigated for 8 to 10 hours. After fumigation, at least 1 week's vacant period is allowed. Disinfecting the drinking water with bleach powder takes 30 minutes. Add 2% of iodine 5-6 drops per kilogram of drinking water, only 15 minutes to achieve the disinfection effect; use of peracetic acid spray disinfection, generally takes 10 to 20 minutes, if the use of fumigation, it takes 1 to 2 hours When manure is disinfected with lime milk, the lime milk should be in contact with the faeces for at least 2 hours.
