The high temperature in summer is the biggest obstacle to raising chickens. Chickens don’t have sweat glands, so they can’t evaporate sweat to evacuate the heat of their own bodies. Therefore, we should artificially cool the chickens. The following small series will introduce you to several common farm cooling measures.
First, we must improve the internal and external environment of the chicken house and strengthen the function of cooling and heatstroke prevention.
Try to enhance the heat insulation capacity of the roof and walls to reduce the solar radiation heat entering the house; set up a sunshade net or sunshade outside the window to prevent the sun from directly illuminating the chicken flocks; insist on removing feces every day in the house to reduce the production of feces in the house Heat; improve ventilation conditions, increase the area of vents and roof skylights; do a good job in the surrounding greening of the chicken house to reduce radiant heat, but also absorb carbon dioxide, reduce dust density, and purify the air inside and outside the house.
Secondly, take necessary measures for heatstroke prevention.
Increasing the wind speed in the house can take away the heat produced by the chicken body. If the wind speed in the house can reach 1-1.5 meters per second, the heat stress of the chicken can be reduced; after the house has a certain wind speed, it can be sprayed in the house Use water evaporation to lower the temperature of the house, but do not spray water in the house at noon, and do not sprinkle water on the ground. High temperature and high humidity chickens are easy to die. Conditional chicken farms can adopt vertical ventilation to install wet curtains. Basic It can ensure the safety of the chickens in the summer; let the chicken drink cool drinking water. The lower temperature drinking water can reduce the heat stress of the chicken. The cool groundwater can be used. The water should be placed at the end of the water pipe for about 2 hours. Make the water temperature in the water pipe lower.
The third is to use drugs to improve the resistance of chickens to heat stress.
Vitamin C is the best medicine for heatstroke prevention and cooling. It is recommended to double the amount used in the summer. If the death is serious, increase the amount of vc alone. Sodium bicarbonate and vc can not be used at the same time will reduce the effect; later days can use cheap baking soda 0.2% Mixing to relieve a series of reactions caused by respiratory acidosis, but it is not recommended to use it for too long to avoid the increase of intestinal pH, you can use some Chinese herbal medicines such as borneol and mint. In the treatment of heatstroke chickens, when using vc, Zhengda or Pulsatilla powder or neomycin, colistin, lincomycin and other drugs effective for enteritis must be added.
