How to do well in winter pig farm insulation in advance

3. In the open hanging curtain pig farm, the air hole is opened during the day, and the hanging curtain is covered with grass curtain and heated in the house at night. 2. The pig lying area is paved with plant ash, lime and furnace ash for moisture absorption and deodorization. 4. Power exhaust fans are installed on the roof to regularly remove harmful and toxic gases and dust, but the exhaust time should not be too long to avoid excessively reducing the temperature in the house. 6.

With the advent of winter, thermal insulation of pig houses in winter shall be done in advance to avoid harm and loss to pig production due to cold climate and sudden change of weather in winter. The following is how to do a good job in the thermal insulation of pig houses in winter.

1. Clarify the harm of low temperature in pigsty

1.1. It has a great impact on the survival rate of piglets, such as piglet extrusion, reduced lactation, easy thinning, etc.

1.2. Slow growth of finishing pigs and reduced feed remuneration.

1.3. Reduce the disease resistance of pigs and are prone to infectious diseases; Low temperature and high humidity are also easy to cause the decline of sow production performance, such as limb and foot diseases, resulting in the abnormal elimination of sows.

1.4. The normal production capacity of the pig farm is reduced, such as reduced disinfection effect, affected employees' working mood, inactive work and a series of problems.

2. Measures for thermal insulation in winter

2.1 before winter, prepare enough heating energy, such as electricity, coal, gas and firewood. Thoroughly check the power supply line, timely check and repair the heating equipment to ensure its normal operation.

2.2 check the doors, windows and glass of the pigsty, and replace and repair the damaged ones in time; The ventilation places of walls and roofs shall be blocked, but ventilation holes shall be reserved.

2.3. Prevent and solve the problem of large temperature difference between day and night in pig houses in winter in advance, because the impact of large temperature difference on pigs is no less than that of low temperature.

2.3.1 automatic temperature control device shall be installed in the pig house to set a suitable temperature range, and the heating equipment can be started or closed according to the temperature range.

2.3.2 when the temperature is high during the day, open some windows or open the unpowered exhaust fan on the roof; When it is cold at night, increase the heat supply and close the doors, windows and exhaust holes to ensure that the temperature difference between day and night is relatively reduced.

2.3.3 in the open hanging curtain pig farm, the air hole shall be opened during the day, and the hanging curtain shall be covered with grass curtain and heated in the house at night.

2.3.4 hang two baking lamps with different watts above the piglet incubator, switch different bulbs according to the temperature, or control the temperature by adjusting the height of the bulb. The judgment standard is that the temperature is appropriate for piglets lying evenly, too high for scattered lying, and too low for lying together.

2.4. On the premise of ensuring the temperature, reduce the humidity, harmful gas concentration and dust in the pig house as much as possible.

2.4.1 train pigs to drain feces and urine at fixed points, and clean up the feces and urine of pig houses in time.

2.4.2 plant ash, lime and furnace ash shall be spread in the pig lying area for moisture absorption and deodorization.

2.4.3 disinfection shall be carried out when the temperature is high, and the disinfection gun head shall be screwed into a fog for spraying.

2.4.4 power exhaust fans are installed on the roof to regularly remove harmful and toxic gases and dust, but the exhaust time should not be too long to avoid excessively reducing the temperature in the house.

2.4.5. Use special drugs or facilities to remove harmful and toxic gases in closed nursery and nursery, or install electrostatic precipitator to remove dust in the nursery.

2.4.6. Adopt the instantaneous ventilation method, that is, turn on the longitudinal exhaust fan to discharge harmful and toxic gases in a short time (the length of the pigsty can be opened for 3-5 minutes and the length can be opened for 1-2 minutes). This method should be carried out at the highest temperature in a day.

2.5. It is not advocated to increase the feeding density of pigs to ensure the temperature in the pig house, because it will increase the concentration of toxic gases in the house and increase the risk of respiratory diseases and other diseases of pigs.

2.6 in winter, crude salt shall be added to the disinfection pool outside the house to ensure the effectiveness of the disinfectant and prevent freezing.

2.7. Timely repair the water pipes and drinking fountains in the pig house to prevent leakage.
