Strengthen management and reduce stress
Temperature: There is a large temperature difference between day and night in spring. Pay special attention to night temperature management. It is better to keep the broiler closed. It is advisable to control the temperature in the house at 16°C~23°C.
Humidity: As the temperature rises, the water vapor inside the house increases gradually. If it is not timely ventilated, it can easily create conditions for the growth of bacteria. Therefore, the breeding households should open the window ventilation at noon and afternoon to reduce the humidity inside the house.
Ventilation: In the spring, due to the unpredictable temperature, it is difficult to handle the relationship between ventilation and heat preservation in the coops. If excessive emphasis is placed on the heat insulation of the coops and the ventilation and ventilation are neglected, bacterial diseases such as E. coli disease can easily be outbreaks; Hot weather can easily cause greater stress on chickens, and it can easily induce mycoplasma and infectious rhinitis. If there is a conflict between the two, ventilation is more important than holding.
Illumination: Keeping the households in the light of the chicken house must grasp the following principles: the lighting time and light intensity of the broiler house should be kept relatively constant, and the semi-open house should be shaded on the sunny side, and the house must be kept in the light. "Only increase without reduction" principle, the lighting time should be maintained at 16 to 17 hours.
Stress: Spring laying hens are sensitive to changes in the external environment due to physiological changes. Therefore, there must be a certain time and order for chicken feeding, adding water, quail eggs, and disinfecting. In addition, it is necessary to listen to the weather forecast in time, understand the weather changes, and take precautions. Such as: 2 to 3 days before the arrival of cold air can be added to the drinking water in the chicken and Meihua instant multi-dimensional, increasing the number of feeding.
Do a good job of prevention and timely remedy
Antibody testing: In addition to normal immunization of laying hens this season, the breeding households should do a good job of replenishing new infectious diseases such as Newcastle disease and bird flu. Conditional chicken farms should conduct an antibody test according to the status of the flock, discover hidden dangers in time, and make timely remedy.
Drug prevention: In order to reduce the stress caused by seasonal changes to laying hens, farmers should add drugs for prevention in feed or drinking water. Such as the addition of cod liver oil, instant multi-dimensional, Vitasal solution to prevent chicken stress, add anti-virus drugs Ankang, Daoxing, clear to prevent viral diseases.
In short, the weather in the spring is fickle, and it is very difficult for farmers to ensure that they are foolproof. Therefore, they must be more careful and careless than usual, or they will cause great economic losses.
