Temperature and humidity control problems in breeding houses

Temperature and humidity control problems in breeding houses
Temperature and humidity control problems in breeding houses

Suitable temperature for laying chickens in laying hens:
The brooding temperature of the egg chicks is 35-33 ° C for 1-2 days, 33-32 ° C for 3-7 days, and about 2 to 3 ° C for each week thereafter, about 21-18 ° C for 5-6 weeks. . Whether the temperature of the supply is appropriate, in addition to observing the thermometer, should also observe the behavior of the chick. For example, when the temperature is normal, the chicks have a good appetite and good appetite, moderate drinking water, quiet sleep, comfortable sleeping position, and more undulating, and the chicks in the entire brooding house are evenly distributed;

When the temperature is high, the chicks are far away from the heat source in the laying broiler breeding equipment, the two wings are unfolded, the neck is stretched and gasps, the drinking water is frequent, and the appetite is not good;
When the temperature is low, the chicks are densely packed in the chicken cages and as close as possible to the heat source. They are crowded and trembled, and they emit a burst of cold and cold, and the appetite is diminished.
Chicks are more sensitive to cold and warm, so pay special attention to prevent the temperature from rising and falling, and try your best to maintain temperature balance.
When the temperature is mastered, the temperature is higher at night or in the rainy and snowy days;
During the day, the chicks are active, the weather is warm, and the temperature should be lower;
The temperature of the weak chicks should be higher and the temperature of the chicks can be lower.

(2) Appropriate humidity for four layer vertical brooding cage: The humidity is closely related to the evaporation of water in the chicken body, the emission of body heat and the cleanliness of the house.

1 When the temperature is high and low humidity, the water in the chicken is not dispersed too much, which may lead to dehydration of the chicks. In addition, due to drying, the dust inside the house is flying, and it is easy to induce respiratory diseases.

2 When the temperature is low and high humidity, the house is cold and humid, and the chick is prone to cold, causing the litter to be wet, and the gastrointestinal disease and coccidiosis occur.

3 When the temperature is high and high humidity, the heat in the chicks is not easy to be emitted normally, suffocating, appetite is falling, growth is slow, and resistance is weakened. In general,

The laying house of the laying hens should be kept dry to prevent bacterial growth and infection, but the relative humidity should not be lower than 40%. Suitable relative humidity: 60% -65% before 10 days old and 50%-60% after 10 days old. When the humidity is insufficient, water can be sprayed on the inner corridor, the ground, the surrounding walls or the flue. The water can be evaporated on the heat source to increase the humidity inside the house. When the humidity is too high, the moisture barrier can be laid on the ground of the chicken house. Appropriately raise the temperature in the chicken house, strengthen the ventilation and ventilation, and raise the litter in the flat chicken house to remove the damp feces and litter in the house in time to prevent the drinker from leaking.
