How to keep warm in piggery in winter?

1. Coal stove

Ordinary coal-fired heating facilities are often used in areas with cold weather and abundant supply of lump coal. The fuel used is lump coal, which has the advantages of fast heating speed and convenient movement, and can be installed and used at any time, and can be used for piggery emergency.

2. Honeycomb coal stove

The fuel used is honeycomb coal, and the heating speed and quantity are slower and less than those of coal stove, but it is used in many parts of the country because it is convenient to use without smoke. The advantage is that it is convenient to move, can be installed and used at any time, and there is no need to install a chimney in an emergency, which is more convenient than a coal stove.

3. Fire wall

The fire path made of bricks and other materials near the wall of the piggery has better thermal insulation performance, and the fire wall is mostly used in colder areas. If the fire port is set outside the piggery, it can also prevent adverse effects such as soot or dust.

4. Ground kang

The lower part of the pigsty is designed as a fire path. When the fire burns below, the ground will keep a certain temperature, because the heat is emitted from the bottom up. The fire kang can not only keep a suitable temperature, but also ensure the temperature of pigs when the temperature of the pigsty is low, which greatly saves the cost. In addition, the floor kang can be designed to burn firewood, and the fuel is cheap weeds or crop straws, which can reduce the cost. In the agricultural areas with abundant straw, small pig farms have sufficient manpower, which is very affordable.

5. Floor heating

It is similar to a kang, but the difference is that a circulating water pipe is buried in the cement floor. When heating is needed, the boiler water is heated, and the hot water is pumped into the circulating water pipe in the cement floor through a circulating pump to raise the ground temperature. This method is used in many pig farms, and the effect is very good, and it does not occupy the ground area, and the old pig house is also easy to rebuild. If the thermal insulation layer is laid under the cement floor to prevent the heat from radiating below, part of the cost of coal burning can be saved.

6. Water heating

Water heating used by residents, but because pigs are generally in a low position, the heat of water radiators is rising, the heating effect is average, and the investment is large, covering a large area, and the usage is decreasing.

7. Air heating

Same as water heating, the heating speed is faster, and it is easy to meet the temperature requirements of various pig houses. The disadvantage is that it requires higher boiler workers and is not suitable for small pig farms.

8. Plastic shed

Farmers use the most common facilities for raising pigs, with less investment and convenient use.

9. The electric air conditioner

has a large investment and high cost, and can only be used in an emergency.

1. Hot air blower

, also known as air conditioner for livestock and poultry, blows the heat from the boiler to the piggery through the fan, and the temperature in the piggery is even, clean and sanitary, and the price is much cheaper than that of electric air conditioner, which is used in many large pig farms.

11. infrared lamp

Local heating is a good choice, which is suitable for emergency, especially for newly transferred pigs. It is easy to operate and very popular with breeders.

2. Precautions for safe heating

1. Furnace smoke

It is a common phenomenon when using coal stoves, honeycomb coal stoves or fire walls, especially when making a fire, which often makes the room smoky. In a relatively dense pigsty, the air quality is obviously deteriorated, which is not conducive to the health of pigs. In addition, some pig farm coal stoves or honeycomb coal stoves are not equipped with chimneys, which is easy to cause carbon monoxide poisoning. Because pigs are more tolerant to carbon monoxide than people, they often cause chronic poisoning without being found, so when using coal stoves or honeycomb coal stoves, chimneys must be installed.

2. Fire

The phenomenon of fire caused by heating occurs from time to time, especially in piggery with wooden structure. The chimney must be kept away from flammable materials. At the same time, in the heating season, personnel should be arranged to be on duty at night to prevent accidents.

3. Humidity of plastic shed

Plastic shed is prone to excessive humidity in winter, mainly because the moisture in the pigsty cannot be discharged, so when using plastic shed, vent holes should be reserved at the top of the shed to prevent excessive heat loss from the vent holes. It can be considered to cover the vent hole with a straw curtain at night, which will not affect the ventilation, but also play a role in heat preservation. When building a plastic shed, if it is designed in the form of a straw curtain that can be easily uncovered, it is more conducive to pig production to cover the straw curtain at night and uncover it during the day.

4. Water circulation of heating and hot blast stove

The phenomenon of poor water circulation of heating and hot blast stove occurs from time to time. Once the circulation is blocked, hot water will not be delivered in place and cannot play a role in heating. Another phenomenon is that due to poor design, the heating pipe is not uniform, some areas are very hot, and some areas are not, resulting in uneven temperature in the pigsty.

5. Use livestock and poultry air conditioners reasonably

Livestock and poultry air conditioners are not as reliable as electric air conditioners, and there are often some problems. If you don't know how to use or maintain them, it will often lead to unusable conditions. Sometimes manual control is needed to adjust the air conditioning. Therefore, when buying air conditioners for livestock and poultry, the operating instructions must be kept well. Generally, minor problems can be adjusted with reference to the instructions. This phenomenon often occurs when changing breeders or electricians.

6. Don't ignore the air quality

In cold weather, the piggery is often tightly closed, and the amount of fresh air is small, so there is often insufficient oxygen in the piggery, which affects the production of pigs. Therefore, don't ignore the air quality when keeping warm, so as not to lose sight of one thing.
