The pig house needs to be ventilated in winter, basically how should it be ventilated?

Winter is the most common cause of pig respiratory diseases, and farmers must do a good job of keeping the pig farm warm and preventing colds if they want to control the occurrence of pig respiratory diseases. In winter, there is a large temperature difference between indoor and outdoor pig houses. In this case, the pig farmer must not only ensure ventilation, but also maintain the temperature inside the pen.

The temperature outside is very low at night, so we should do a good job of cold protection and insulation, and during the day the temperature outside is relatively high, so we can ventilate the pigsty during the day. The ventilation of the pig house must follow the principle of "windless ventilation and shelter". To ventilate the pig house, one is to reduce the ammonia concentration in the pig house, the second is to reduce the humidity of the pig house, and the third is to remove the dust and dust in the pig house to provide a good growth environment for the pig house.

In the early and mid-stage management of winter pig production, pig farmers should not only do a good job of ventilation, but also do a good job of heat preservation. In winter, when there is no wind and the temperature rises, pig farmers can ventilate the pigsty. Every day from 10 a.m. to 3 p.m. is when the temperature is high.

During this time, the pigs can open the windows of the barn to ventilate. If the cold air comes and the temperature is very low, the pig farmer should properly ventilate the pigsty so that the skylight and bottom of the pigsty can be opened and ventilated.

In the later management of winter pig production, ventilation should be the mainstay. If pig farmers use mechanical ventilation equipment, it is recommended to use inverter fans for ventilation. If the conditions are limited, as long as there is no ice in the pigsty, the doors, windows, skylights and other vents in the pigsty can be opened, and the air quality in the pigsty must be ensured.

1. Pig farmers should fix the pigsty. They should repair and replace the pigsty so that thieves don't get into it. 2. Pigs should be disinfected.

Pig utensils, pig clothes, and pig hats should be thoroughly cleaned and disinfected regularly. 3. Pig farmers should do a good job in the prevention of pig diseases and use pig vaccines according to the actual situation. 4. Pigs should control the drinking water of pigs.

In general, drinking water for pigs in winter should be two to three times the feed intake. Therefore, pigs should not be given too much drinking water.

You can install some ventilation equipment, or open the ventilation window of the pig house, which can ensure that the pig house is clean and tidy.

The best way is to use ventilation equipment directly, which can speed up the air flow in the injection room, and can also play a good role in ventilation, and will not cause the piglets to catch a cold.

A small opening can be made next to the barn, so that there is a ventilation effect, and it can also be ventilated through the exhaust system.

Just open a small opening, don't keep pouring cold air, about half an hour ventilation is the best.

For pig herds, winter is the most likely to cause respiratory diseases. If pig farmers want to control the occurrence of respiratory diseases in pig herds, they must do a good job of thermal insulation and cold protection of pig houses. In this case, pig farmers should not only ensure that the pig house is ventilated, but also maintain the internal temperature of the pig house, so how should the pig farmer solve this contradiction?

1. Ventilation and thermal insulation contradict each other, can it be left without ventilation?

As the herd grows, the amount of sewage, manure, feed dust and other harmful substances in the barn increases, all of which produce harmful gases. In general, the concentration of ammonia in the barn is 25 mg kg. In the case of low winter temperatures, if the pig farmer does not ventilate the pig house, the concentration of ammonia in the pig house will exceed 100 mg kg.

Pigs live in an environment with high concentrations of ammonia, and harmful gases can cause respiratory diseases when introduced into the respiratory tract of the herd. In severe cases, it can lead to the death of a large number of pigs. Therefore, pig farmers must pay attention to the ventilation of pig houses.

In real life, some pig farmers are afraid that the pigs will be frozen, so they do not ventilate the pig house, or only ventilate it for a short time. In fact, this practice is often harmful to pigs. This will make the pig herd live in an environment where harmful gases exceed the standard, and these harmful gases will enter the pig herd, on the one hand, it will cause the pig herd to suffer from respiratory diseases, and on the other hand, it will reduce the immunity of the pig herd, thereby inducing a variety of diseases.

Therefore, pig farmers should adopt a reasonable way to ventilate the pig house.

2. How to ventilate the pig house best?

The outside temperature is low at night, so it is necessary to do a good job of cold protection and thermal insulation, and the outside temperature is relatively high during the day, so the pig house can be ventilated during the day.

When ventilating the pig house, pig farmers must follow the principle of "ventilation if there is no wind, and shelter from the wind if there is wind".

We ventilate the pig house, one is to reduce the concentration of ammonia in the pig house; the second is to reduce the humidity of the pig house; The third is to eliminate the dust and dust in the pig house, so as to provide a good growth environment for the pigs.

In the early and mid-term management of pig herd production in winter, pig farmers should not only do a good job of ventilation, but also do a good job of heat preservation.

In winter, pig farmers can ventilate the barn when there is no wind and the temperature rises. Between 10 a.m. and 3 p.m. every day is the time when the temperature is warmer, and pig farmers can open the windows of the barn for ventilation. In case of cold air and low temperature, pig farmers should properly ventilate the pig house, and the skylight and bottom window of the pig house can be opened for ventilation.

In the later management of pig herd production in winter, the pig house should be mainly ventilated and ventilated. If pig farmers use mechanical equipment for ventilation, it is recommended to use frequency conversion fans for ventilation, such as Jiafeng negative pressure fans, which can be equipped with special fan frequency converters, which can adjust the air volume by speed and adjust the ventilation volume according to different air temperatures.

If the conditions are limited, as long as the inside of the pig house is not frozen, you can open the doors, windows, skylights and other vents of the pig house, and be sure to ensure that there is good air quality inside the pig house.

1. Understand how air moves. Not in a straight line – except at high pressure, but in a "bubble", which rotates mainly up and down (warm air rises) as the distance changes. The trick here is to control the air flow so that it passes through the pig's back (about meters and seconds at normal temperature);

2. Follow the first rule: you need a fumigant to judge the air flow, and the beekeeper's wiping gun will do.

3. Usually ventilate the manure area first, and the pork chops last. In hot conditions it's the opposite.

4. Similarly, under normal circumstances, the air flow time is long. This ensures good air mixing and that the hogs are not exposed to cold air. On a hot day, it's the opposite.

5. The fan does not direct air, but a controllable air intake. Therefore, the air inlet closure and fan speed must be connected by the controller.

6. Exhaust is optimal, not pressurized, because in a well-sealed building, the exhaust fan must draw air from a controlled inlet.

7. According to the number and weight of pigs, determine their maximum and minimum air demand.

1. You can buy some exhaust fans and place one at intervals, which can effectively help ventilate the pig house and have a good effect. If the ventilation effect is good, some fresh air can be brought in, the pig house will not feel stuffy, and they will grow healthier.

2. Natural ventilation should control the length of ventilation, ventilate for half an hour each time, and ventilate twice a day to replace a better environment for the pig house. If the time is too long, the temperature in the pig house will be greatly reduced, affecting the growth of pigs, the overly cold temperature is easy to make pigs cold, ventilation for half an hour, keep them warm in time, pigs will not be easily harmed.

The high ammonia content in the pig house in winter is mainly caused by the environment being too closed, and if you want to reduce the ammonia content in the pig house, you can strengthen ventilation. When raising pigs in winter, the sanitary management of the pig house must be in place, the temperature in winter is very low, and the breeding density of the pig herd cannot be too large, otherwise it will also lead to an increase in ammonia. An appropriate amount of starter culture can be added to the feed of pigs, which can effectively reduce the ammonia content.

1. How to remove ammonia in the pig house in winter

1. If the pig house is too closed in winter, it will lead to high ammonia content. If you want to reduce the ammonia content, you must strengthen the ventilation to exhaust the ammonia in the house. There are many ways to ventilate, you can open the fan to fill in new air, or you can open the vents, doors and windows for ventilation.

2. When raising pigs in winter, we must do a good job in the health management of the pig house. The feces and urine produced by pigs must be removed, pigs should not be allowed to drink contaminated water, and the environment in the house should be kept dry.

3. Due to the low temperature in winter, some farmers will appropriately increase the breeding density in order to keep the pigs warm, so that the body temperature of the pigs will rise. However, it should be noted that the feeding density should not be too large, otherwise it will also cause the ammonia content to be too high.

4. When feeding pigs, an appropriate amount of starter can be added to the pig's feed, which can also reduce the ammonia content. Because the starter culture can enhance the digestive capacity of pigs, so that pigs can make full use of the conversion feed and improve feed utilization.

2. How to keep the pig house ventilated in winter

1. When ventilating the pig house, it must be carried out under the condition of a large temperature difference between the inside and outside of the pig house, and the ventilation will be easier at this time. If the temperature in the barn is not high, the farmer can open the window on the leeward side for ventilation when the sun is shining. However, do not open the skylight for ventilation in winter, otherwise the temperature in the barn will be lost.

2. If affected by the conditions and can not be both ventilated and insulated, then you can ventilate first, which can reduce the concentration of harmful gases in the pig house. When cleaning the manure of the pig house, it must not be washed with water. Because the temperature is low in winter, the water does not evaporate easily, which will lead to an increase in the humidity of the pig house.

3. When building a pig house, we must do a good job of thermal insulation facilities. Only if the pig house has good thermal insulation performance, many problems can be avoided. There are many kinds of insulation facilities, such as: baking lamps, electric heating plates, floor heating, ondols, hot blast stoves, etc.

Summary. Hello, glad that your question is answered as follows:

Poor ventilation in winter mainly causes relatively little oxygen in the pig house, which affects the slow growth of pigs, reduces disease resistance, and harmful gases, especially ammonia, will cause damage to the mucous membrane of the respiratory tract of pigs, and are prone to respiratory diseases. Therefore, it is also a science to master the temperature and ventilation of the pig house in winter. I hope mine is helpful to you.

Ventilation is an important guarantee to maintain the quality of the environment in the house, and it is also necessary to ventilate in the low temperature season to improve the air quality in the house. Different sizes and specifications of pig houses can be ventilated in different ways, in short, including natural ventilation and mechanical ventilation. Therefore, before the construction of the pig house, the ventilation measures in the house during the operation should be planned in advance.

In addition to the effectiveness, the ventilation of the pig house should also consider the cost and take into account the local geographical and climatic conditions. For example, the southern boar barn (fully enclosed) is usually cooled by water curtains, and the broiler barn (semi-open) is usually naturally ventilated with manual roller blinds installed at both ends of the side wall vents, and the cooling effect is enhanced by a combination of spray and longitudinal mechanical ventilation during the high temperature season.

Summary. Hello, more than happy to answer your questions!

Pig farm ventilation generally uses fans to achieve active ventilation, and side ventilation is commonly used.

Ventilation is carried out according to the condition of the pig house. It's best if it's the hottest time of the day, but if the smell is high, ventilate more frequently.

How to ensure the ventilation of the pig house?

Hello, more than happy to answer your questions! Pig farm ventilation generally uses fans to achieve active ventilation, and the usual ventilation is the side ventilation of the dust store. The Genpai bucket sedan chair is ventilated according to the situation of the pig house.

It's best to be late for a day when the temperature is at its highest, but if the smell is high, the frequency of ventilation should be higher.
