In winter, the pig house is closed tightly and easy to produce ammonia, how to remove the ammonia in

It is best to strengthen ventilation and open vents or doors and windows at noon to remove their feces in time.

The best thing to do is to ventilate the barn regularly, so that most of the ammonia can be removed.

The ammonia in the pig house is in the upper position. In general, the density of ammonia is 0.771g per l, and the air is dense to the land.

1.293g per l, the density of ammonia is less than the density of air will float on top of the pig house. However, ammonia is produced by pig manure and feed residues on the ground, which will be mixed in the air.

Introduction to ammonia. Generally speaking, the density of ammonia is less than the density of air, and it will float on it, but the wheel friends always produce ammonia rising gas on the ground, so ammonia will be mixed in the air, if you use an exhaust fan to pump, you can install the exhaust fan in the window position, the molecular weight of ammonia is 17, the molecular weight of air is 29, ammonia is lighter than air, so in general the ammonia is on it, because the ammonia concentration in the house is very high due to sealing, so what we have to do is to ventilate and disperse the ammonia in the pig house.

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.

The ammonia in the pig house is heavy, and it is necessary to open the window at noon every day to ventilate the pigsty, so that the ammonia is discharged from the pen, and to reduce the production of ammonia, the pigsty can be cleaned once a night to avoid fecal fermentation, and to ensure that the pig house is dry and hygienic, quicklime needs to be placed in a humid place to absorb water.

1. Ventilation

When raising pigs, it is necessary to open the window at noon every day to circulate the air in the environment and discharge the ammonia from the pigsty, or install ventilation equipment inside the pigsty, which can quickly discharge harmful gases and will not affect the temperature in the pens.

2. Cleaning

When raising pigs, if the pig manure is not cleaned in time, it will lead to the fermentation of pig manure and the production of ammonia, you need to clean it every night to clean out all the manure in the pigsty, and you need to splash bleaching powder or quicklime on the pen every other week to disinfect and sterilize, so that the pig can grow healthily.

3. Ensure dryness

When raising pigs, you need to change the litter once a day, you can replace it with soft and dry straw to avoid the wet litter containing more toxins, and to place quicklime in the more humid place in the pen to promote its absorption of water.

4. Feeding management

When raising pigs in winter, it is necessary to provide soybean cake, wheat, rapeseed cake and other foods with high protein and energy content, provide cold tolerance for pigs, and regularly sprinkle environmental improvers in the pig house to make the organic matter in the pen decompose quickly and inhibit the reproduction and growth of harmful microorganisms in the house.

1. When you feel that the smell of ammonia is big, the harmful gas in the house is not only ammonia, if the smell of ammonia is large, the first thing to solve the problem of ventilation and eliminate harmful gases.

2. The second is to reduce the production of harmful gases, ammonia is mainly fermented by urine, and at the same time, protein fermentation will produce hydrogen sulfide, which are two harmful gases in the pig house.

3. The timely removal of urine can effectively solve the production of ammonia, and reducing the protein content in the feces can reduce the production of hydrogen sulfide, one is to improve the digestion and absorption function of pigs to improve the feed conversion rate, the other is the timely removal of manure, and the third is to reduce the environmental humidity, which can also reduce the fermentation of protein.

4. If the pig feeding density is the same as in summer, then the manure can be cleaned once a day in summer, but in winter, it must be cleaned twice a day.

5. If the temperature in the enclosure is too low, it will affect the digestive function of the pigs, so that the feed can not be fully digested and absorbed, and the protein content in the manure file is increased, and the pig's intestines are easy to produce gas, and the gas produced is mainly hydrogen sulfide.

Ammonia has become a problem that many farmers are concerned about, and here, the probiotics of the production department of Shenzhong Science and Technology have played a very good role in this regard: usage and dosage: 1. Deodorization of enclosures:

First of all, you have to know how ammonia comes from, bacteria decompose nitrogenous substances in the feces, first of all, add microecology to the feed to promote the digestion and absorption of nitrogenous substances in the feed, and then remove the feces in time, and the third is to ventilate frequently, and do these things well.

There are two main types of ammonia in the barn: one in the gastrointestinal tract, ** in feces and urine, gastrointestinal digests, etc., urine nitrogen is mainly in the form of urea, which is easily hydrolyzed by urease and catalyzed to produce ammonia and carbon dioxide. Fecal nitrogen is mainly in the form of organic matter, which is not easy to decompose, but it is also a ** nitrogen in the process of ammonia formation.

The other is ammonia in the house, which is produced by the decay and decomposition of organic matter such as accumulated manure, feed residues and bedding. Ammonia is produced faster when the litter is moist, the pH is suitable and the temperature is high, and there is a lot of manure and there is considerable air. The content of ammonia in livestock and poultry houses depends on the temperature in the house, feeding density, ventilation, ground structure, feeding management level, manure removal, etc.

Since ammonia is highly soluble in water, the concentration of ammonia in high humidity air is relatively high. According to Balins, 50 80 kg pigs discharge 6 kg of manure and urine per day, containing 16 37 g of nitrogen, of which about 60% are urea or ammonium salts and other substances that are easily converted into ammonia.
