The high temperature in summer is very uncomfortable, and the chicken is an animal without sweat glands. So what kind of management methods should be used to raise chickens in summer?
The first is the way of cooling and cooling. It is a good practice to choose the water curtain cooling system. 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, the air after the cooling enters the chicken house, and flows from the one end in a laminar flow state. At the other end, the door is finally discharged, so as to achieve ventilation, cooling and ventilation in automatic poultry farming.
When the curtain is cooled, attention should be paid to the tightness of the house. Except for the water curtain and the fan outlet, the rest must be sealed to prevent the short circuit of the hot air and affect the cooling effect. Always check whether the equipment is intact and damaged, and repair it in time. If the chicken is short of water in 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. In the case of ensuring safety, all immunization activities should avoid hot weather as much as possible. For chickens in the laying period, in addition to drinking water immunity, other immune activities are best arranged after the lights are turned off 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 extent of heat stress.
