After a summer heatstroke, I didn't worry about pigs.
"Pig sweat glands are undeveloped and their body temperature regulation ability is poor. When the pig house temperature rises to 35°C, the pigs can easily cause heat stress syndrome. If the pigs grow slowly, they stop growing weight, and if they lose weight, they will suffer from heat stroke." Northwest Agriculture and Forestry Technology Zhou Hongchao of the University College of Veterinary Medicine believes that the following three points should be paid attention to in summer cooling of pigs:
The heat insulation of piggery is to prevent heat transfer outside the house. The strength of the insulation depends on the thermal resistance value and heat storage performance of the building materials used. The external resistance is high and the heat storage capacity is strong. The structure, less heat transferred into the house, the internal surface temperature of the external protective structure is low, can reduce the heat radiation of the inner surface of the pig, so we should choose the appropriate external protection material and structure to ensure the ideal heat insulation effect.
Shading and greening pig farms should be built in ventilated and open areas. Before the high temperature season arrives, a simple pergola is constructed using fireweed, branches, etc. on the sunny side of the pig house.
In order to reduce the temperature of the surrounding environment of the pig house, certain facilities may be used to cut off the solar radiation. A horizontal plate may be added to the window to block the sunlight coming from above the window; for a pig house with a playground or a solar greenhouse, it should be used in summer. Set up pergola or plant vine shade.
Ventilation In summer, when the temperature in the house is higher than the outside, the ventilation can bring the heat out of the house. It can also increase the speed of the airflow in the house. When passing through the pig, it will take away the heat and promote the pigs. Evaporation heat dissipation.
Kelp is rich in nutritions and multipl minerals.It make people full but diets. It is the most favorite choice of people with hypertension, hyperlipemia, hyperglycemia.
