The tolerance of chickens to high temperatures is greatly affected by moisture and ventilation. Temporary high temperatures, chicks have a certain ability to adapt and adjust, but in a long period of high temperature environment, chicken body temperature regulation mechanism can not resist, if more than a certain limit, the chick will die.
At high temperatures, the chicks showed puffing, staying away from heat, laziness, loss of appetite, increased drinking water, and decreased or elevated body temperature, causing the chicks to die. Even if there is not a large number of deaths, due to high fever, it will affect the appetite of the chicks, cause hunger, stagnate growth and development, and induce other diseases.
Death of chickens caused by high temperatures, generally no obvious lesions, only visible gastrointestinal emptiness, pulmonary congestion, congestion and edema. There are two reasons for the high temperature environment of the chicks. One is that the outside temperature is too high, the humidity inside the house is too large, the ventilation performance is poor, and the chicks are dense. The second is the failure of the thermometer, or improper positioning and height of the thermometer. It is impossible to correctly judge the temperature inside the house, causing overheating in the house, or uneven heat distribution.
