As the temperature rises, layer farming gradually into the water curtain cooling phase, but the beginning of the recommended transitional use of water curtain, to avoid a sudden cold cold situation, for example, in the hot summer high temperature and humidity. If we use water curtain in high temperature and high humidity. Must pay attention, if this time if the continuous use of water curtain. It's easy for the chickens to get too cold, and the humidity in the coop rises quickly. This high humidity gives the chickens a stronger sense of body temperature. Second, it will occupy a lot of room with oxygen, and it will cause the chicken coop to suffocate. This suffocating will cause the chicken to die from lack of oxygen, so the water curtain is most suitable for intermittent use. Then, according to the temperature, humidity, water Curtain opening is also different, when the relative humidity is & LT; 60% high temperature and low humidity weather, if the maximum temperature of the day is below 35 ° C, the use of air cooling; if it is greater than or equal to 35 ° C, the need for wet curtain cooling, start-up temperature 32 ° C, relative humidity ≥70% high temperature and high humidity weather, if the maximum temperature of the day is less than 32 ° C, use air cooling cooling; if it is greater than or equal to 32 ° C, need wet curtain cooling, start-up temperature is 30 ° C, 80% relative humidity extreme high temperature high humidity weather, if the maximum temperature of the day below 29 ° C, use air cooling cooling; if greater than or equal to 29 ° C, need wet curtain cooling, starting temperature of 28 ° C, at the same time can be combined with anti-heat drugs to improve the ability to adapt to environmental heat stress and reduce the body temperature on the body damage, I wish you a safe and efficient summer breeding.
