In terms of inventory data, as of the end of the third quarter of 2020, the national live pig inventory was 370.39 million, an increase of 9.0% over the end of the second quarter.

1. National frequent policy – to ensure the stability of live pig prices and the healthy development of the industry

According to rough statistics, there are about 10 policies related to live pigs in 2020, of which 2 are about African swine fever. At the beginning of 2020, the State Council issued the “Opinions on Doing a Good Job in Sannong and Ensuring a Well-off Society in an All-round Way as Scheduled”, and put forward the goal of ensuring that the production capacity of commercial pigs will return to a relatively normal level in 2020.

2. The dual effects of “African Swine Fever” and “New Coronary Pneumonia”

(1) African swine fever

As the country further increases its investment in animal epidemic prevention, various prevention and control measures have been implemented in various places, and African swine fever has been eliminated, and major pig epidemics have been effectively controlled. The epidemic intensity of swine fever and other diseases has been decreasing year by year, the frequency of the incidence has been greatly reduced, and the scope of the disease has been significantly reduced. New outbreaks have dropped significantly, and Hainan, Liaoning, and Jilin Yongji have established immune-free areas for foot-and-mouth disease. Major pig epidemics such as foot-and-mouth disease were generally stable, and no major regional pig epidemics occurred.

African swine fever has also had an impact on the hog industry:

In the absence of an effective vaccine, the ASF virus cannot be completely eradicated, and the probability of occurrence can only be reduced by improving the industrial environment and enhancing the level of prevention and control. Compared with the initial stage, the current key epidemic prevention work has been strengthened in terms of illegal transfer of live pigs Since March this year, 13 cases of African swine fever in domestic pigs have been reported nationwide, most of which were caused by illegal transportation. The advantages of one-stop breeding and slaughtering enterprises are more obvious, and the risk of cold chain transportation of white meat can be greatly reduced.

African swine fever also affects the pig industry
01The impact on pork prices
It is inevitable that the price of live pigs in the epidemic area cannot go out of the province, while the price of pigs in the sales area may rise steadily due to the shortage of supply.
02 “South pigs are raised in the north” to cool down
There are two places that farming and animal husbandry giants are most enthusiastic about: the northeast and southwest, and the African swine fever was first discovered in the northeast, which will also make the investment of farming and animal husbandry enterprises face a round of policies and the test of the epidemic.

In addition to potential disease, air pollutants resulting from poor indoor ventilation can also negatively impact pigs and house staff. So pig houses that are closed during winter need to focus on indoor air quality. As well as avoiding health problems such as reduced growth rate and poor reproductive performance of pigs caused by cold stress.
Overall, these potential risks that come with winter could affect our normal farm operations. So our number one priority is to make sure these problems don’t get caught up in the winter, thus avoiding economic damage.
The main factors that affect air quality include:
1. Is it possible to ensure good ventilation in the venue?
2. Regional and seasonal changes
3. Feeding system and density
4. Animal Nutrition
Getting your barn ready for winter is key to focusing on air quality and nutrition. Some pollutants in pig houses are mainly ammonia, carbon dioxide, carbon monoxide, hydrogen sulfide, methane and some airborne microorganisms. Collectively, these pollutants adversely affect animals and, if not mitigated, can cause significant health and performance issues.

????

1. How cold stress affects feed intake

One nutritional challenge that pigs face when experiencing cold stress is increased metabolic heat production, which means they require more nutrients to maintain, but also directly affects pig growth. And in the process of cold stress, the greater ad libitum intake of pigs also leads to poor feed conversion rate, increased input costs, and decreased pork quality, which has a negative impact on cost control in general.
Why is this happening? In growing pigs, the thermoneutral zone is the most comfortable and productive zone in which pigs are able to maintain body temperature and perform optimally (Figure 1). Pigs experience cold stress when the temperature drops below the critical lower limit for pigs. When the temperature was lower than the critical lower limit, the feed intake increased, but the daily gain decreased.

2,、What does ammonia have to do with it?

?

Ammonia, a dangerous gas produced during the decomposition of urine, is a major source of air pollution in pig farms and negatively affects pig performance. Its harmful effects on pigs are:
1. Reduce food intake
2. Decreased growth performance
3. Increased mortality
4. Reduced reproductive performance of sows

Ammonia is formed when excess nitrogen is excreted in urine and feces in the form of uric acid and urea. This is an issue that requires our attention because cold stress can affect the gastrointestinal tract of pigs, resulting in reduced nutrient intake and feed conversion ratios in pigs. And when a pig’s gastrointestinal tract is under stress, it cannot absorb nutrients properly, causing important nutrients to be excreted in waste.

3. 7 Tips to Prepare Your Pig House for Winter

01. Check your ventilation system

Static pressure is the driving force for ventilation. Check the pressure difference between the inside and the outside of the room and make sure that the main ventilation (usually side walls and ceiling entrances) are not restricted. Especially on older farms, check for condensation and leaks. The leaky pig house has poor ventilation in winter. Tune your ventilation system based on your environment and animal feedback.

02. Not all fans are created equal

Realize that each fan should be adjusted differently, and a 24-inch fan in one barn may not have the same effect as a 24-inch fan in another barn. Different environments can affect ventilation, so adjustments should be made accordingly. It is also important to know what the maximum static pressure of your equipment is. Also, remember to consider the fan’s energy efficiency and fan air flow ratio when starting to run the fan’s minimum ventilation in the coming months.

03. Keep equipment clean

Extreme cold conditions can make cleaning, cleaning and disinfection of equipment and facilities very difficult. Dirty shutters and limited air intakes can negatively impact air flow, ventilation and air quality within the barn, which in turn can lead to poor livestock performance. Make sure blinds, shades, air intakes and other items are kept clean.

04. Fresh air distribution is critical

Make sure the fresh air is distributed correctly to avoid dead spots or cold spots throughout the barn. Proper placement and operation of barn air intakes and the use of static pressure are key. Make sure the air goes through your designated inlet and not through the cracks in the barn.

05. Insulate from cold surfaces

If possible, place materials such as insulating foam paper in front of cooling curtains, unused high-temperature fans, access doors, and other cold areas. Not only does this help create a better seal, but it also provides insulation from cold surfaces, just like regular wall heaters to pigs.

06. Make sure the barn is sealed

If the barn is not sealed, it is difficult to ensure proper ventilation. For example, if there are any leaks and/or cracks in the barn, the fresh air will take the path of least resistance and not be fully filtered, potentially negatively impacting on-site biosecurity. Ensuring the airtightness of the barn is about having complete control over how and where the air enters the barn.

07. Make sure your controller is set up correctly

Remember to clean the temperature probes and make sure they are in the correct location (eg: not too close to heaters or inlets etc). Make sure the temperature is measured correctly at the correct location in the barn to help better control the cost of propane heaters.

4.? Nutrition Tips to Reduce Cold Stress in Pigs

01. Understand how the environment affects voluntary feed intake

Understanding the effects of cold weather on pig feed intake is extremely important. Timely adjustments to diet formulations are therefore key to ensure that as the weather cools, pigs get the nutrients they need while maintaining optimal animal performance,。

02. Feed ingredients with high heat gain to pigs

Provide pigs with feed ingredients that produce more calories during digestion. This can be achieved by adjusting the fiber content of the feed. Fiber is highly digestible, so feeding more fiber to pigs will naturally produce more calories when the pig digests fiber. However, be aware that fiber can affect pork quality, as feeding high levels of fiber in finishing pigs can reduce pork production.

03. Reduce the crude protein content of the diet

Reducing the crude protein content of the diet can reduce nitrogen production, thereby reducing ammonia emissions in the barn.

04. Ammonia reduction in pig houses through feed additives

Deodorant from Alltech, a natural plant yucca extract rich in polysaccharide components, has been scientifically proven to reduce ammonia and its harmful effects in the environment, while increasing animal weight gain and feed efficiency, reducing Animal morbidity.

Deodorant effectively reduces the concentration of ammonia gas in pig houses

Deodorant increases average daily gain in pigs

The reason is that among the factors that can determine productivity and performance, investment facilities are very important (Housing First). Pig health refers to the coordination and strengthening of the immune system. The immune system is influenced by a combination of innate genes and acquired, feed and water, farm facilities, and growing environment. The congenital gene of the pig farm is a matter of selecting breeding pigs, and the acquired part is the part that can be solved by the facility management of the pig farm. Let’s take a look at the main facilities management keys and methods that pig farms need to do.

All diagnoses are persistent, centralized, and observation begins

Pigs are living beings that can be affected by the surrounding environment just like humans. If you do not pay attention to the environmental management of pigs eating, sleeping, and playing, it is difficult to obtain the desired results. Pigs are not as verbal as humans, so it is important to observe the pig’s living pattern and give the pig an appropriate environment after a correct diagnosis.

When raising livestock or grain, we can see the different growth process of livestock and grain every day, which can make farmers feel good results. The core element of the success of the pig industry is that in the environment where the four seasons of the country are clearly distinguished, the pig growth environment needs to be continuously and periodically observed and the best environment must be provided.

When we face some problems that need to be solved, there may be mistakes. Because the fundamental reasons are not clear, just looking at the appearance will make mistakes in solving the problem. When faced with any question, the answers you need are not far away, common sense is in the nearest place. If there is a problem with the pigs raised, carefully observe the pigs to find out where the problem is.

For example:

1) The vitality of the piglets decreases. When the piglets accumulate in one place, it tells us that it is caused by excessive ventilation, poor room sealing and the environment where the outside cold air is implanted.

2) When pigs play with water and drink more water than usual, it tells us that the temperature in the pig house is too high.

3) When the sow has difficulty panting without eating feed, tell us that the house is high temperature, high humidity and lack of fresh air (hypoxia).

In such an inappropriate pig growth environment, there will be pig growth disorders and disease exposure in the house, resulting in a decline in immunity, which has a malignant impact on production performance.

Pigs need to grow within the specified facility environment. When providing the best environment for pigs, determine the factors that affect disease prevention, growth rate and performance. Therefore, it is necessary to provide physical and biological management techniques in a special space designated for pig life. The environmental management in the pig house is subject to change at any time. The internal environment corresponds to the external environment of the pig house. We need to continuously provide the best environment for pig growth.

1. Deodorant with clever feeding

The stench of the farm mainly comes from a variety of odors, and the composition is relatively complex, mainly caused by the excrement of livestock and poultry, so adopt clever feeding to deodorize. Enzyme inhibitors can be added to the pig’s diet, which can reduce the ammonia content by 50% and the hydrogen sulfide content by 18%. The crude protein content in the pig’s feed is adjusted to 10%. Tryptophan, etc., can reduce nitrogen and ammonia emissions of pigs and reduce stench. For raising chickens, 1%-2% charcoal residue can be added to the chicken’s diet, which can dry the feces and reduce the odor, and also can add 2%-5% zeolite powder, which can also reduce the water content and odor of the feces. It also helps to improve feed utilization.

2. Physical deodorization

Charcoal, activated carbon, cinder, quicklime and other substances have excellent adsorption effect. These substances can be put into a mesh bag and hung in a shed, or sprinkled on the ground, which can not only be similar to the odor in the air, but also play an excellent role. The deodorizing effect can also play a role in disinfection and sterilization.

3. Chinese herbal deodorant

You can use mugwort leaves, atractylodes, big green leaves or garlic straws to burn in a certain proportion in the shed, which can not only deodorize, but also sterilize, especially when the house is empty. It can also be fed with Chinese herbal medicine that clears heat and detoxifies to reduce bacteria in the stomach and intestines, and can also reduce the content of ammonia in the air and reduce odor.

4. Chemical deodorization

The excrement of livestock and poultry should be cleaned in time every day, piled together, and sprinkled ferrous sulfate in it, which can inhibit the fermentation and decomposition of the feces and reduce the odor. And other hydrogen peroxide, potassium permanganate, copper sulfate, acetic acid, etc. also have excellent odor suppression. The ground can also reduce the odor of the chicken house.

5.Wusen Environmental Control Pig House Odor Treatment System tells you three stages of odor removal:
1. Exhaust gas filtration: The exhaust gas discharged from the pig house first enters the buffer room of the system, and the wind speed decreases when the airflow passes through the buffer room, and passes through the deodorization filter material wall of the pig farm at a low speed;
2. Pig farm filter wall: The deodorizing filter material wall is composed of PP regular mesh filter material produced by our company. There is a spray device on the front of the filter wall. After the exhaust gas is sprayed, the humidity increases.
And most of the dust will be absorbed by the spray water and settle into the pool at the bottom of the equipment;
3. Clear circulating water pool: the humidified exhaust gas continues to move forward and enters the filter material (the function of the deodorization filter material in the pig farm is to increase the contact area of the water film on the surface of the gas and the filter material), and the gas
After the body molecules hit the water film, they are absorbed by the liquid, and then flow back to the pool with the water flow, so as to achieve the goal of purification and deodorization of exhaust gas.

2. Take out the fan filter. Rinse with water. In this process, in order to prevent the filter from corroding, it needs to be soaked in water instead of chemicals. At the same time, prevent the water pressure from being too high and prevent the filter from being damaged.

3. When cleaning other parts of the animal husbandry fan, the operator first covers the fan with tape, and then directly connects the tap water to the spray pipe and the cleaning port. To keep it clean, the nozzles can be washed with clean water. In addition, the bottom basin of the livestock fan should also be washed. Cleaning operations should be careful and rigorous to keep systems and components clean.

4. Put the cleaned filter back on the fan and tighten the screws to maintain the reliability of the device.

5. Turn on the main power of the fan again, and it will run normally after about 5 minutes.

Noise Control of Animal Husbandry Fans

The purpose of noise control can be achieved by reducing sound sources, limiting the spread of noise, and hindering the acceptance of noise. In the detailed noise control technology, four methods can be used: sound absorption, noise reduction, sound insulation and vibration reduction.

1. Sound absorption method: Install sound absorption materials around the fan to reduce noise.

2. Muffler method: Install mufflers at the inlet and outlet of the fan to reduce the spread of noise.

3. Sound insulation method: The fan motor is installed in the sound insulation cover to control the spread of noise.

4. Vibration reduction method: Install a shock absorber under the fan motor to control the noise generated by the fan vibration.

5. Others: (add sound insulation and vibration reduction measures according to the actual situation)

The above are the cleaning methods and noise reduction methods of livestock fans. If you want to know other information, you can consult us. Our staff will contact you to help you answer your questions and help you choose suitable products.

In 2020, the national price of live pigs has “twisted and twisted”, out of an “M”-shaped trend, breaking the 19 yuan/catties mark twice, the annual high reaching 19.77 yuan/catties, and the lowest price being 13.62 yuan The price of pigs fluctuated more than 6 yuan per kilogram during the year, but the price of pigs remained at a high level throughout the year. The Founder Medium-term Futures Research Institute predicts that the average price of live pigs in the whole year of 2020 may not be lower than 29 yuan/kg.

The price of pigs in 2020 is unprecedented. It has never been seen before, and it is estimated that there will not be any in the future. Although pig prices in 2020 did not break through last year’s highest point, they remained in a high range throughout the year. Will the price of pigs go up again? Farmers don’t care so much anymore, they are more worried about when the price of pigs will fall, and how sharply it will fall. For example, Tao Yishan, chairman of Tang Renshen, said that “the price of pigs will drop to 10 yuan/catties in 2022, or even 4-5 yuan/catties”, which caused an uproar in the industry and made many farmers start to be vigilant. In general, with the gradual recovery of live pig production capacity, the decline in pig prices is an inevitable trend, and pig raising will also change from racing to cost competition.

7. Imported pork may exceed 4 million tons, 2.5 times the history

According to the latest customs data, my country imported 330,000 tons of pork in October 2020, and the accumulated pork imports from January to October were 3.62 million tons, a year-on-year increase of 126.2%. From the perspective of the whole year, November to December is the peak season for pork consumption, and the import volume of pork in 2020 will easily exceed 4 million tons. It is worth noting that before the occurrence of African swine fever, the historical high of pork imports was 1.62 million tons in 2016. The annual pork import volume this year may be more than 2.5 times that of 2016 and 2.994 million tons in 2019. times more.

Imported pork has never been liked or even rejected by pig farmers. As an important supplementary source of domestic pork supply, this year’s pork imports hit a record high, which to a certain extent also reflects the huge domestic pork supply gap. In addition, under the new crown epidemic, the imported cold chain has frequently tested positive, which also makes the safety of imported meat questionable. With the recovery of domestic pig production capacity and the impact of food safety issues in the global cold chain on pork import trade under the new crown epidemic, the demand for pork imports will gradually decrease in the future.

8. The 26-story high-rise building shocked the industry, and the pig raising project in the building was launched intensively

According to reports, as of the end of July 2020, as many as 64 building pig raising projects have been launched intensively in Sichuan Province. Pig raising in buildings has not only sprung up like bamboo shoots after a rain, but has also grown higher and higher. On August 17, 2020, the foundation stone was laid for the 26-story high-rise pig raising project of Hubei Zhongxin Kaiwei Modern Animal Husbandry Co., Ltd., which shocked the entire pig industry. In addition, according to the statistics of Xinmu.com of Agricultural Treasure Collection, since 2020, Wenshi, Muyuan, New Hope, Luoniushan, Tianzhao Pig Industry, Lihua Co., Ltd. and other pig-raising enterprises have deployed more than 40 pig-raising projects in buildings.

Distribution of pig raising projects in buildings that have been completed and put into production (including projects under construction) across the country

Why is pig raising in buildings suddenly so popular? In the era of the loosest pig breeding policy, in order to seize opportunities and occupy a larger market share, pig enterprises will naturally not let go of the field of building pig breeding under the limited breeding land resources – on the same size of land , The pigs raised are several times that of ordinary pig farms.
Traditional tiled pig farms belong to facility agricultural land, and the approval procedures for building pigs are relatively complicated. In the past, it was really difficult to build buildings to raise pigs. In order to solve the problem of breeding land, in December 2019, the Ministry of Natural Resources and the Ministry of Agriculture and Rural Affairs jointly issued the “Notice on Issues Concerning the Management of Facility Agricultural Land”, and announced for the first time that breeding facilities are allowed to build multi-storey buildings, opening a policy opening. Although building pigs has the advantages of alleviating land use conflicts, improving management efficiency, and high intelligence, the problems of large initial investment in building pigs, high construction costs, and difficult control of major infectious diseases cannot be ignored.

9. Breeding pigs are scarce and over 20,000 are introduced abroad

According to the report on the breeding pig market of the Agricultural Finance Think Tank, as of March 2020, according to the survey data, it is estimated that the national core group of breeding pigs has dropped by about 30% compared with before the occurrence of African swine fever. In the tight supply of purebred and hybrid sows, the prices of binary sows and piglets have also hit new highs. The price of a 40kg sow in a core breeding farm in Henan Province is as high as 8,000 yuan per head. In the second half of 2019, the proportion of ternary sows reserved for breeding began to gradually increase. By the first half of 2020, data from the COFCO Futures Research Center showed that ternary sows accounted for as much as 45% of domestic sows, and it is expected that sows will be scarce within 2 years. The industry attributes will not be changed. At the same time, the introduction of foreign breeding pigs in 2020 also ushered in a “blowout period”. According to incomplete statistics, as of the end of November, the number of purebred pigs imported into my country in 2020 has reached 22,191, and the number has exceeded 20,000, a record high.

2020年部分企業(yè)種豬引種情況（不完全統(tǒng)計(jì)）

The industry leader has been relocated, the pig giant has made a rush, the sky-high market price has been ups and downs, the ASF vaccine has been rejected, the official announcement that the production capacity of live pigs has been restored to 90%… In 2020, every major event has caused the industry Uproar.

1. Muyuan has become the number one pig production in my country

In March 2020, Muyuan Co., Ltd. won the first place in the live pig slaughtering list for the first time, and then the momentum continued to rise steadily. In November, the number of live pigs sold by Muyuan Co., Ltd. exceeded 2 million in a single month. At present, the number of live pigs sold by Muyuan Co., Ltd. in the first 11 months has reached 15.473 million heads. enterprise. Judging from the current situation, there is a high probability that Muyuan Co., Ltd. can achieve the goal of slaughtering 17.5-20 million live pigs in 2020.

From January to November 2020, Muyuan Co., Ltd. sold 15.473 million live pigs, with a cumulative sales income of 48.379 billion yuan

Under the huge gap, whoever can take the lead in the layout and seize more market share will be able to seize the fate of the next stage of competition. Obviously, Muyuan Co., Ltd. is at the forefront of the historical trend. Facts have proved that Muyuan’s self-propagating and self-raising pig-raising model with high assets has withstood the test of ASF, and it has benefited more significantly from the accelerated expansion of production capacity in this round of pig cycles.

2. African swine fever vaccine failed to market

When will the African swine fever vaccine be available? Before the Internet rumors were rampant, the end of 2019, May 1, 2020, National Day in 2020 and other time nodes were all rumored to be magical. However, up to now, the vaccine has not been successfully launched, and it is even reported that the vaccine was unanimously rejected in the expert review process.

The ASF vaccine has been controversial in trials and wait-and-sees. Research on ASF vaccine is the right of scientists. When it can be marketed, it does need to be carefully considered. Many people in the industry say that the current vaccine is not suitable. The African swine fever vaccine is a worldwide problem. If it is put on the market for the sake of listing, it will bring more harm to the pig industry than the epidemic itself, and all the efforts made for the prevention and control of African swine fever in the past two years will be destroyed. At relevant professional conferences, some experts disclosed that wild vaccines already exist in some areas, and the harm is not shallow. After two years of fighting against Africa, Chinese farmers have summed up a lot of prevention and control experience. For some farmers, vaccines are no longer a necessity. We look forward to an effective and safe vaccine, but we can’t completely stress on a vaccine that is still under research and controversy.

3. The six central and southern provinces prohibit the transfer of live pigs

From November 30, 2020, the six central and southern provinces will completely prohibit the transfer of live pigs (except breeding pigs and piglets) from non-central and southern regions. dispatch. When the supply of live pigs and live pig products in the area is insufficient or there is an emergency, under certain conditions, the “point-to-point” dispatch of live pigs can be started, and the straight-line distance in principle does not exceed 1,000 kilometers.

The ban on the transfer of live pigs in the central and southern regions is a favorable exploration for the prevention and control of ASF, but for small and medium-sized pig enterprises in the live pig production areas, selling pigs under the ban has become the biggest difficulty. At the same time, the pattern of “raising pigs from the south to the north” may also be completely broken. In the future, the live pig market will become a sales area market, and the layout of pig enterprises will be more inclined to pork consumption provinces. Each province is responsible for its own supply of live pigs, which is one of the important reasons why local governments have vigorously supported and attracted pig enterprises to raise pigs in the past two years.

4. Officially announced that the production capacity has been restored to 90%, and 2.28 million new farmers have been added.

The Ministry of Agriculture and Rural Affairs stated on December 15, 2020 that according to the monitoring of the full coverage of large-scale pig farms across the country, in November, the number of large-scale pig farms with an annual output of more than 500 heads increased from 161,000 at the beginning of the year to 177,000. There are also more than 15,000 pig farms that have resumed breeding.

1. Deodorization with chemical substances: Some chemical substances can also play a role in deodorization, such as copper sulfate, acetic acid, etc., which can effectively suppress odor and reduce the odor of the air in the chicken house. The specific operation method is that farmers use 4% copper sulfate and an appropriate amount of slaked lime to mix in the litter, or spray the litter with 2% benzoic acid or 2% acetic acid, which can deodorize.

2. Ground deodorization: In the process of using the wet curtain of chicken raising equipment, farmers can also sprinkle a layer of superphosphate on the ground of the chicken house, and then the superphosphate will react with the ammonia gas generated in the chicken manure, An odorless solid, ammonium phosphate, is formed, which can reduce the ammonia gas emitted from the manure of the chicken house and effectively reduce the odor of the chicken house. The specific implementation method is to spread 350 grams of ammonium phosphate evenly on the moving ground of every 50 chickens.

3. Biological deodorization: Many beneficial microorganisms can improve the utilization rate of feed protein and reduce the amount of ammonia gas in the feces, thereby inhibiting the generation of harmful gases in bacteria, which can effectively reduce the content of harmful gases in the air.

The above three points are the deodorization techniques for the wet curtain of the breeding equipment that have been used for a long time, and these methods are also the maintenance methods of the wet curtain. The farmers are finished using the wet curtain of the breeding equipment After cleaning, it must be cleaned in time, as well as regular disinfection, so that the odor of the wet curtain will basically not occur.
