How to do a good job in cooling and heat prevention management of chickens prone to diseases due to high temperature in summer

High temperature and humidity in summer, small temperature difference between day and night. Therefore, it is necessary to take measures in accordance with local conditions, look at the chicken method, and make rational use of cooling equipment such as fans and water curtains.

Chicken

First, the problems that are easy to occur in broilers in summer:

1. There is no timely use of the fan, for fear that the chickens will be affected by the wind, resulting in the chickens growing in the environment of ultra-high temperature, high humidity and poor ventilation in the early stage. When using the fan, the air inlet is small and the position is unreasonable, resulting in excessive local wind speed in the chicken house.

2. Because there was no fan in the early stage, the chickens could not bear it in the middle and later stage, so they suddenly used the fan with a large number, long time and high wind speed. Chickens do not adapt to the process, feed intake decreased, suffering from gastrointestinal and respiratory diseases.

3. When using water curtain, it is difficult to master the age of use. It is not clear that the water curtain should be used when the temperature inside and outside the chicken coop reaches, and it is difficult to grasp the number of fans to start. The flocks of chickens catch cold and diarrhea, which can induce the toxic lesions of infectious diseases.

4. Insufficient cooling equipment, power outage, high flock density and so on.

Second, measures to prevent heat and cool down broilers in summer:

1. Enhance the thermal insulation of the chicken house: about 60% of the solar radiation heat enters the chicken house through the roof in summer. Increasing the thermal insulation of the roof is the most effective measure to prevent heat and cool down in summer. For example: to increase the thickness of the roof, straw curtains thicker than 20cn can be used to cool the chicken house by 3-5 ℃. In addition, laying a shade net on the top of the whole chicken house and extending the chicken house more than 3 meters to the sunny side can reduce radiation and reduce the temperature by more than 3 ℃.

2. Installation of exhaust fans: 2000 chickens, 6 installed, 3 per bed, 5mi 7m away from the door, distance between fans 11m 14m. Using the relay blowing method, the maximum air volume is 8 Mel 9 cubic meters per kg of body weight.

3, the use of spray cooling: chicken house ridge, installation of water pipes, piercing some small eyes, water pump flushing water pipe, natural spray, this method is practical, convenient and economical.

4. Administration of anti-heat stress drugs: sodium bicarbonate, Vmurc, Huoxiang Zhengqi, etc.

5. use traditional Chinese medicine for preventing heat and cooling: patchouli, Angelica dahurica, Su stem, Pueraria, Atractylodes, Yunling, Scutellaria, Phellodendron, plaster, Radix Isatidis, Shuanhua, Forsythia suspensa, licorice and so on. Use the formula according to the chicken weight of 0.5ml / kg.
