Regulating a good temperature and humidity layer chicken high yield

First, the temperature control temperature on the chicken's activities, drinking water, feeding, physiological conditions and metabolic intensity have an impact. The variety, breed, and area of ​​the chicken vary in their adaptability to temperature. Therefore, the influence of the ambient temperature on different flock is not the same.

The suitable temperature range for laying hens is 5-27°C. The egg laying rate is high at 13-15°C, and the egg laying rate can be maintained at 10-24°C. When the laying hens are lower than 4°C or higher than 29°C, the egg production rate is Obvious drop.

Lower temperatures have little effect on egg weight and shell thickness, but higher temperatures can affect egg weight and shell thickness. When the ambient temperature is often higher than 21°C, the shell becomes thin and the ambient temperature is higher than 24°C. At that time, the weight of the egg began to drop. The higher the ambient temperature, the more pronounced the drop in egg weight.

Ambient temperature has an effect on the feed intake and feed efficiency of the chicken. The lower the ambient temperature, the more energy the chicken needs to maintain it and the more it feeds. Egg production performance is highest when the ambient temperature is between 21 and 24°C. If the ambient temperature is often below 7°C or above 27°C, feed efficiency will generally decline.

Therefore, in order to obtain the highest egg production level and the highest feed efficiency, try to maintain the temperature in the house at 8-27°C.

Second, the humidity control In general, relative humidity has little effect on chickens, but in extreme cases or in conjunction with other factors, it may also cause serious damage to chickens. Therefore, the relative humidity inside the house cannot be ignored.

Suitable relative humidity for chickens is approximately 70% for chicks and approximately 60% for laying hens. However, in the production practice, the relative humidity will fluctuate. In addition to being too high or too low, adjustments are generally not made. For a variety of chickens, 50% to 75% relative humidity is more appropriate. And as long as the ambient temperature is more appropriate, the relative humidity is reduced to 40% or higher than 80%, and the impact on the chicken is not great. There are differences in the relative humidity requirements of different feeding methods. Under appropriate temperature conditions, 80% relative humidity may have little effect on cage chickens, but loose-breeding chickens on thick litters are on the high side.
