Keeping a pig farm warm is the key, how to do a good job of keeping a pig farm warm?

For the northern regions, most of it is already winter. Since yesterday afternoon, it has been windy and rainy in my hometown, and the lowest temperature this morning has reached minus 2 degrees, which is indeed very cold.

Every winter, it is time for farmers to cheer up and carefully manage the pig farm, because there is a difficult thing to deal with in winter is the insulation problem of the pigsty.

And the sow is <>

It is the most important thing in the pig farm, coupled with the good pig price this year, it is not easy to buy sows at ordinary times, so it is necessary to take care of the sows in the pig farm, and the most important thing for sows in winter is to keep the pig house warm, so that the sows can have a warm environment to wait for delivery.

Raising sows in rural areas, although not as good as the facilities in large-scale pig farms, there are also many ways to make the pig house warm, and the following is a brief introduction to several methods.

1.The outside of the pigsty is covered with a thick layer of plastic film.

For example, the pig farm in the countryside of my family has covered the outside of the pigsty with a thick layer of plastic film before the beginning of winter. Some farmers are more careful and buy a new and complete piece of large plastic film that can cover the entire row of pigsty every year.

Then the plastic film used last year is thoroughly disinfected, and then covered with a new film, so that it becomes a two-layer plastic film, and the overall heat preservation is better.

2.The new pig house is underfloor heating, and the old pig house uses an electrified cement slab.

If the pigsty is newly built, then it is better to spend more money to do underfloor heating directly when it is built. If it is an old pigsty, the farmers here often use a homemade electrified cement board as a insulation board.

In fact, you can use an insulation board for piglets, but this insulation board is used for sows all winter. The piglet is small in weight, it doesn't matter if it uses a thermal insulation board, the sow has such a heavy body lying on the thermal insulation board all day long, and it is estimated that it will be used several pieces in winter.

In fact, this kind of electrified cement board is very simple to do by itself, that is, when making the cement board, add a few circles of wires inside, and connect the wires on the outside when you use it, and use it more in autumn and winter, and the insulation effect is not as good as the electric heating board, but the cost is small and the use time is long.

3.A charcoal stove is used in the sow house and charcoal is burned every day for heating.

In winter, when it is the coldest time of 3949, or when the sow is about to give birth to the piglet, add a few more carbon stoves to the sow pen to burn charcoal for heating, but this stove needs farmers to often guard the watch point, and then do a good job of the flue, so as not to leak smoke.

Summary. Many people are reluctant to raise sows, that is, they feel that raising sows is too troublesome, especially in winter, and if they do not pay attention to the usual management, it will cause problems with sows or piglets with a small birth weight.

This year's pig raising ** is so good, many people want to raise sows are not, so now sows are very expensive, newborn piglets ** are very high, as long as the sows are managed well in winter, then the next year will definitely be able to raise pigs for a great harvest.

With the development of recent years, China's breeding industry has developed rapidly, and the scale of the farm has gradually increased, choosing a suitable, good heating effect, safe and reliable heat exchanger equipment has become a matter that HVAC engineers need to seriously consider. Due to the excellent product performance of finned tube radiator equipment and the economy of the product, finned tube radiator has become the first product considered by HVAC engineers when choosing heat exchange equipment.

Finned tube radiator.

Finned tube radiator is a widely used heating equipment in gas and liquid heat exchanger, which mainly achieves the purpose of enhancing heat transfer by adding fins to the base tube. Spiral finned tube radiator is a more commonly used one, spiral finned tube radiator is the use of professional processing technology to make the fin into a spiral shape, the processing technology of the spiral finned tube radiator greatly increases the heat transfer efficiency of the finned tube radiator.

Spiral finned tube heat sinks often work in dusty and humid environments, which requires finned tube heat sinks to have more powerful product performance. The anti-oxidation capacity of the spiral finned tube radiator is incomparable with many radiators, and the spiral finned tube radiator adopts the professional technology of internal and external double-layer anti-corrosion, which greatly improves the anti-corrosion ability of the finned tube radiator; The anti-dust accumulation ability of the spiral finned tube radiator is also very strong, even if there is dust on the finned tube, it will not affect the heat dissipation effect of the product.

In winter, when the temperature is low, how should the pig house take warm and warming measures? The specific measures are as follows:

1. The outer wall should be thick and tight.

The back wall, gable, and front wall of the pig house should be insulated in winter. Crop straw can be stacked, and adobe can be built temporarily. It is best to thicken the four walls of the periphery when the pig house is first built.

2. The ground should be dry.

Fecal sewage should be removed in time and cleaned up. In order to facilitate drying, the pig house should be made of cement floor.

3. Add bed boards.

In the piglet stage, where conditions permit, it is best to use warm bed boards such as wooden boards, bamboo boards, and thickened fiberboard, and cement prefabricated boards can be laid without conditions.

4. Increase the temperature of the pig house.

First, the open pig house is covered with plastic film. It is best to cover with double-layer plastic film, although the cost is higher than that of single-layer plastic film covering, but the insulation effect is better. This method is suitable for fattening and non-lactating sow houses.

The second is the implementation of boiler heating in the closed pig workshop. The third is the open pig house heating heating and plastic film covering. The fourth is heating and electric heater, which is suitable for lactating sow houses.

5. Increase the number of feeding.

The purpose of increasing the number of feedings is to increase feed intake relatively to make up for the weight deficit caused by body fat and intramuscular metabolism thermogenesis caused by low temperature. Where conditions permit, it is best to take ad libitum feeding. In places where there is a fixed feeding, it is possible to increase the feeding once in the evening.

6. Improve the energy level of feed.

It can be increased by about 10% on the basis of the original feed energy level. Big pigs are low, small pigs are high. Small pigs can add oil and fat high-energy feed, and large pigs can increase the number of common energy feed such as corn in the compound.

7. Increase the lighting area of the pig house.

The open pig house should have a large open area to prepare for the winter to be covered with plastic film for lighting. In the case of closed barns, windows should be reserved on the south wall and roof for the installation of glazing in winter.

Add a greenhouse, just like the kind of vegetable growing.

Relaxing leaves is best! Lay a floor in the pig barn!!

I think build a lance shed.

Add some materials. Or pour some ashes into the pigsty.

Or fill in some dry soil.

In recent years, air source heat pump heating has shown its skills in animal husbandry and has been favored by the market. Like the heating method of pig farms and pig houses, they basically tend to choose air energy heat pump heating. Why is air source heat pump heating on fire in the pig industry?

The advantages of air source heat pumps are, first of all, power saving. The air source heat pump absorbs the heat in the air, and the heat can be doubled by consuming a small amount of electricity, and the power consumption of the air source heat pump is about 70% less than that of the electric product.

The second advantage of air source heat pumps is the constant temperature, which can improve the comfort of pigs. The more comfortable the pig is, the higher the growth rate, and the more willing the farm owner is to invest. Now the pig's ** is better, the growth rate of the pig is high, and the more the pig farm owner can make money.

The third benefit of air source heat pump heating is to achieve intelligence, no need for people to manage at all, only need to adjust the temperature, unless the equipment fails, otherwise it does not need to spend too much manpower and material resources, virtually saving a labor cost.

The fourth benefit of air source heat pumps is that the equipment is stable, unlike other forms of heating, where there is not enough temperature. If the temperature does not meet the heating needs of the pig, the user has not found it in time, the pig may catch a cold and cough, increase the incidence of the pig, and cause losses.

The 3,500-square-meter farm in Anping County, Hengshui City, Hebei Province has adopted Gemei Yue air energy heating. According to the actual measurement of pig farms, in 32 days of heating, the electricity consumption of heat pumps is kWh. Calculated that the average daily power consumption of the equipment is less than 53 kWh. The cost of electricity in the area is yuan.

Therefore, pig farms use air energy heat pumps for heating, and the cost is about 26 yuan. Compared with traditional electric underfloor heating, the heating expenditure is greatly reduced. The owner of the pig farm also expressed satisfaction.

Pigs are closed and ventilated, sows and piglets are added with warm lights, and biogas can be used with biogas boilers!

1. You can buy heaters and other equipment.

2. Block the ventilated place so that the air can circulate.

3. Lay a mat on the roof to keep you warm.

4. Feed the pigs warm food.

As soon as the pigs are moved, the ventilated place is closed, and the sows and piglets are warmed by the lamp.

I saw that my aunt's pig farm was covered with a large plastic sheet...

In the cold winter, when the outside temperature is too low, in order to maintain normal body temperature, the pig body must enhance the oxidative decomposition of substances in the body and produce heat energy to supplement the loss of body heat. Generally speaking, when the temperature around the piglet is between 20 and 26, the metabolic consumption is low and the growth and development are normal. However, large pigs have lower metabolic consumption at 15 to 20 and normal fat gain.

Therefore, in the actual feeding management of pigs in winter, it is necessary to pay attention to the cold and thermal insulation measures of the pig house, increase the temperature in the house, reduce the consumption of pig metabolism, in the severe winter, not only does not affect the growth and fattening, but also can promote its growth and development and fattening. The specific measures are as follows:

First, the anti-thief wind is through the gap in the pen to enter the attack pig body. When the pig is asleep, it will cause colds, pneumonia and other diseases, so it is necessary to plug the leaks and gaps in the enclosure, and the windows or ventilation holes of the pig house should be more than meters from the ground.

Second, the application of plastic greenhouse simple enclosure covered with plastic film, can effectively increase the temperature of the pig house more than 7, reduce cold stress, reduce energy consumption.

3. Increase the feeding density of a pig is a "heat source", that is, the higher the density, the higher the temperature. Farrowing sows, each occupying 4 square meters, a litter in a pen; Empty pregnant sows, each occupying square meters, 4 square meters of captive 2 3 heads; 6 8-month-old gilts occupy square meters per head, and 7 8 pigs are kept in captivity for 4 square meters. The above enclosure includes eating.

Drinking water, resting place, in the rest place (lying area) should be used in the method of lying full circle, that is, in the lying area can be full of pigs, do not leave a gap, and to keep the lying area clean and dry.

Fourth, reduce the humidity of the pig houseThe greater the humidity of the pig house, the greater the heat lost by the pig body, and the more cold the pig feels. In order to prevent moisture, the circle should change the hay and dry soil frequently, and the fecal urine should be discharged regularly and fixedly, generally 4 or 5 times a day and night. Due to the increase in the number of pigs in the urine nest in winter, the humidity in the house increases.

Therefore, in addition to training pigs to "three-point positioning" (eating, urine, and sleeping in a fixed position), the feed should not be too thin when feeding.

Fifth, the bedding grass in the increase density at the same time the application of thick bedding grass circle, it is an effective way to prevent moisture insulation in winter, bedding grass (wheat straw, straw, sawdust) ** wide, used up bedding and pig manure together fermentation for organic fertilizer. The method of using the bedding circle is to put 20 30 cm of grass baffle in the pig lying area, and the grass baffle is best made of brick and cement; Place the standing bricks 5 cm under the ground, and the remaining 19 cm on the ground, use cement to build the bricks into a grass baffle with a height of 20 22 cm, and add the bedding to the lying area to prevent the bedding from scattering and pigs from pooping and peeing in the lying area.

Pig farms can choose finned tube radiators for warmth, and the finned tube radiators in breeding farms are commonly made of steel pipes with higher heat transfer efficiency, and can also be made of aluminum pipes with higher heat transfer efficiency, but the cost of aluminum radiators will also rise, so there are more users who choose steel pipes for finned tube radiators in the actual use process.

Finned tube radiator.

Farm finned tube radiator is used in a large area of farms, it must have a more efficient heat transfer efficiency, and the heat dissipation efficiency of the radiator has an impact in addition to raw materials, but also related to the method of making the radiator, in which the winding method is a better heat transfer effect, because in the process of winding the steel pipe, it will increase the heat exchange resistance of the radiator.

Finned tube radiator.

The common warmth method of pig farms recommends two kinds of equipment suitable for heating in the farm, one is to use the finned tube radiator to heat the radiator, and the other is to use the light pipe radiator to dissipate heat and heat. The following is a brief introduction to the advantages and characteristics of each of them.

The finned tube radiator for breeding is usually installed in the wall-mounted mode, which is stable and reliable, and is usually installed on the wall by the window, so that the heat can be directly offset by the heat load when the cold air enters, and the heating effect of the radiator will be improved to a certain extent. Finned radiators are made of steel and connected by reliable and stable welding technology, and they play a very important role in agricultural and industrial heating systems.

Fin radiator.

The raw materials of the finned radiator are all steel pipes that meet certain standards, and stainless steel, aluminum and other materials can also be used for processing. The finned tube radiator for breeding is usually made of steel pipe structure, the connected radiator is injected with water or steam, water and steam are used as the heat transfer medium, and the surface of the radiator is the main carrier for heat dissipation, and the temperature in the breeding shed and planting shed is raised by heating the air.

Fin radiator.

The diameter of the steel pipe used in the steel light pipe radiator is generally commonly used, and the diameter is generally 2 inches, 3 inches, and can reach 6 inches. The larger the diameter of the light pipe radiator, the better the heat dissipation effect. The structure of the light pipe radiator is "S" type, and different pipe diameters can be selected according to people's needs.

The steel light pipe radiator B-type has a compact structure and a wide range of applications, which can be used in various large-area places. It can use its own heating machine to grind and use convection heat dissipation to heat the heat directly with the cold air in all corners of the room. It can also be changed according to the use environment of the light pipe radiator, the indoor thermal insulation performance, the outdoor temperature and other skills.

Optical pipe radiator.

The steel light pipe radiator is usually wall-mounted, which saves the indoor space to a greater extent, and because the hot water type of the light pipe radiator has ground legs, it can also be installed in a standing form, which makes the radiator more stable and safer to use. The surface of the steel light pipe radiator B type is smooth, the appearance is simple, not only beautiful, can adapt to the environment of a variety of fields, and the smooth surface is not easy to accumulate dust, even if there is dust, the blind can be gently wiped with a wet rag, easy to clean, and used in a variety of fields.
