Environmental suitability

In the climate environment with high humidity and high temperature, we must first create dry, clean and quiet environmental conditions to ensure the safety of fattening cattle during the summer. In summer, we should minimize the time for fattening cattle to bask in the sun, and the activities of fattening cattle should be reduced as much as possible between 10 and 18 o 'clock.

Put up a shelter from the sun

In summer, a pergola can be built on the top of the cattle house and the playground to cool down. To prevent direct sunlight, vines such as grapes and loofah can be planted. If necessary, a layer of straw, wheat straw and other insulation can be added to the top of the barn. The walls of the barn can be coated with fresh lime paste to reduce the radiation of sunlight on the barn.

Reasonable density

The breeding density of the fattening cattle house in summer should not be too large, and the area occupied by each cow should be increased, so that the wind surface is large and the cattle will be cooler.

Ventilation and cooling

Mechanical ventilation for cooling. Mechanical ventilation or other forced ventilation measures are adopted to eliminate the dirty air in the barn and reduce the barn temperature. In the hot weather with small air volume or no wind, you can turn on the ventilation, according to the need to use electric fans or large exhaust fans, but the use should be reasonable, the large exhaust fans should be installed in the north wall, so that the wind is straight and the body can be cooled 2 ° C ~3 ° C.

Natural ventilation and cooling. When the weather is hot, all doors and Windows and ventilation holes should be opened, and surrounding obstacles should be removed to promote air convection and ensure smooth ventilation.

Spray water to cool down. Splashing water on the ground of the cattle playground (or shed) to cool down; Water spraying from the roof of the cattle barn to cool down; After 12 o 'clock every day, the cold water just from the well is sprayed in space with a high-pressure sprayer, and the spray is performed once every 2 hours to 4 hours, which can reduce the temperature in the house by about 5℃. In summer, you can also hang a water curtain at the entrance of the door and window of the cattle house, which can make the air in the house cold and wet, if you can connect a sunshade outside the door and window, the cooling effect is better.
