The summer heat is very uncomfortable, and the chicken is an animal without sweat glands. In thebattery cage for layers, there are fewer places to move, and it is more likely to cause heat stress in the chicken. What kind of management method should be used to raise chicken in summer forpoultry farming equipment?

The first is the way to cool and cool. Choosing a water curtain cooling system is a good practice. The basic principle is the principle of water evaporation and heat absorption. The external high temperature air is usually unsaturated, and the unsaturated hot air acts under the negative pressure of the induced draft fan. Under the wet curtain, the vapor pressure of the water is higher than the vapor pressure of the air, causing the water to evaporate and take away the moist heat in the air, so that the gas is cooled, and the cooled air enters the house and flows out from the end in a laminar flow state. At the other end, the door is eventually drained for ventilation, cooling and ventilation in automatic poultry farming.

When the curtains are cooled, attention should be paid to the tightness of the house. Except for the water curtain and fan outlet, the rest must be sealed to prevent shorting of hot air and affect the cooling effect. Always check that the equipment is intact and repair it in a timely manner. If the chicken is short of water during the hot season, it will increase the degree of heat stress and even lead to a large number of deaths. Therefore, in the breeding season, if you encounter hot weather, you must ensure that the breeder supplies water throughout the day. All immunization activities should avoid hot weather as much as possible while ensuring safety. For chickens during laying, in addition to drinking water immunity, other immune activities are best arranged after turning off the lights at night.

In addition, the house can use a shade net to prevent direct sunlight from lowering the temperature of the house. If necessary, add some anti-stress additives to the drinking water or reduce the stocking density of the house. The degree of heat stress.
