Professional pig farmer using the fermentation bed method interviewed by CCTV-7
CCTV-7 interviews a professional pig farmer using the fermentation bed method
CCTV interviews a professional pig farmer using the fermentation bed method. Reporter: Well, this is strange. This pigpen doesn't have much of a smell. Just now, when I passed those other pigpens, I could smell that indescribable odor from far away. What's going on here? Let me find someone to ask.
Factory Manager Chen: This kind of farming is a new method, called the fermentation bed pig farming method.
Reporter: Fermentation bed pig farming method?
Factory Manager Chen: That's right.
Reporter: How is this technology different from the pig farming methods we've used in the past?
Factory Manager Chen: With the original traditional pig farming method, all the pig's urine and manure stayed inside, and once it was flushed with water, it was washed outside, causing pollution to the environment. Our factory was listed by the Zhenjiang Municipal People's Government as a unit required to rectify within a deadline. But now that we've adopted this technology, the environmental protection has improved, and in addition, the quality of the pigs has improved, and the meat sells for a higher price.
Ha, every salesman praises his own wares. Is this technology really that good? Let me ask a worker.
Reporter: Young man, how is pig farming going now that we're using this fermentation bed pig farming technology?
Worker: With this technology, we workers have it easier.
Reporter: How is it easier?
Worker: The pig manure and urine, we don't need to deal with them at all. We just add feed and that's it.
If I hadn't seen it with my own eyes, I really wouldn't believe it. Pig farming without having to clean up pig manure, that saves a huge amount of trouble. But what puzzled Wen Wei was, the pigs eat, drink, and relieve themselves all in the pen, so why is the pen neither smelly nor dirty? It's quite hot, so why aren't there any flies buzzing around?
Reporter: I never would have imagined that in my life I'd be sitting inside a pigpen chatting. This is Mr. Shen, the person who introduced the technology. Let me ask, what exactly is this technology about?
Mr. Shen: This fermentation bed pig farming is exactly like its name suggests. It uses organic bedding material to build a fermentation bed, and the fermentation bed absorbs the manure and urine. In addition, the microorganisms in the fermentation bed decompose the manure and transform the feed.
Once the manure is decomposed, the odor naturally disappears. So it turns out this is all thanks to microorganisms. Mr. Shen and his team found through experiments that it takes only 3 days for the manure to be decomposed by microorganisms into very fine powder, disappearing without a trace. At the same time, the manure provides nutrients to the bacteria, and the beneficial bacteria keep multiplying, forming mycelium. These high-protein substances then become a delicacy for the pigs. When the pigs eat them, it not only aids digestion but also boosts their immunity. The entire fermentation bed forms a perfect little "biosphere," which can be described as zero-emission, pollution-free organic agriculture.
Mr. Shen: Look at this bed, it's loose and soft, and it doesn't stink.
Reporter: Very dry.
Mr. Shen: Like sand.
Reporter: Let me smell it.
Mr. Shen: Does it stink?
Reporter: No, it doesn't stink. It has an earthy smell.
Mr. Shen: There's a slight fragrance of soil microorganisms, no stench of manure.
Reporter: How thick is this?
Mr. Shen: The thickness is about 80 to 90 cm.
Reporter: I notice it's quite warm here.
Mr. Shen: Right, fermentation is underway underneath.
Reporter: Right, it's quite hot.
Mr. Shen: The fermentation process generates heat. After it heats up, a large amount of moisture in the material evaporates, and the odor is decomposed by microorganisms, so the bed is very clean.
Reporter: That's why we can sit here and chat.
Mr. Shen: We can sit here, and our bottoms won't get dirty either.
Pigs raised on fermentation beds have returned to a "native, natural" environment. They're in a good mood and aren't shy around strangers. When Wen Wei came, they treated him like a visiting neighbor, untying his shoelaces and busily scratching his itches. When the pigs are happy, their appetites are hearty, their bodies are in great shape, and they eat everything with relish. When they have nothing to do, they run around happily. Every one of them has a shiny coat and a body full of lean muscle.
My colleague Wen Wei, after spending most of the day enjoying happy times with the pigs, even figured out a few things.
Reporter: I've discovered that this bedding bed has three functions. First, a trampoline.
Reporter: Second, a Simmons mattress.
Reporter: Third, an electric blanket. Look how happy it makes them!
Reporter: The bedding bed from earlier was quite fun. What material is it made of?
Mr. Shen: This one, we just built a new one. Let me take you to see it, okay? The material for this fermentation bed is mainly wood chips, plus clean soil and salt. As for the soil, it needs to be clean soil that hasn't been exposed to chemical fertilizers or pesticides, because it contains a lot of microorganisms. Also, for the salt, coarse salt should be used.
The bedding material is mainly wood chips, accounting for 90%, with the other 10% being soil and a small amount of salt. The wood chips are very loose and soft, and can absorb moisture; adding coarse salt helps decompose the wood chips.
Reporter: Alright, now our fermentation bed bedding material is ready. I should proceed to the last step, which is also the most critical step, which is to evenly spread these bacterial cultures into the fermentation bed. These bacterial cultures, let's see what they look like, and take a sniff. There's a smell like steamed buns that have gone sour. Mr. Shen just told me that these bacterial cultures are collected from the soil, then cultured in a laboratory, and that's how they become like this. Now I need to carefully and evenly spread these bacterial cultures. Time to get to work.
After mixing the bacterial cultures evenly with the bedding material, let it ferment for 4 to 5 days, and then the pigs can get on the bed.
Reporter: What about the height needed for this bedding bed?
Factory Manager Chen: The height is generally 80 cm to 90 cm. In the south, where the groundwater level is relatively high, we generally use the above-ground type. If in the north, where the groundwater level is relatively low, the underground type can be used.
The height is also the same, 80 to 90 cm.
Pigs entering the pen must first be thoroughly dewormed.
Whether the fermentation bed works well is also related to the construction of the pig house. Generally, the pig house should face north with its back to the south. This kind of pen has good lighting, which is good for fermentation; it also has good ventilation, so it doesn't stink and has no mosquitoes or flies. If you use a greenhouse to raise them, it's both easier and cheaper. Because the greenhouse costs less, and the microclimate is easier to regulate. In winter, the lighting is good and it's warm, so the pigs can safely overwinter; in summer, put down the shade film and roll up the surrounding skirt film, which allows for ventilation and cooling.
Reporter: I also noticed that this soil seems a bit darker than the soil I saw earlier.
Deputy Director Dai: These pigs, well, have already been raised for two cycles. The wood chips have already been decomposed by the indigenous bacteria, so the color is coffee-colored.
The expert says that not only does the pig manure and urine never need to be cleaned up, but even the bedding material of the fermentation bed doesn't need to be replaced for 10 or 20 years. Tell me, isn't this kind of worry-free and cost-effective good thing something you'd have a hard time finding even with a lantern? But Wen Wei still had one concern.
Reporter: Is this bedding bed easy to manage?
Deputy Director Dai: Easy to manage, very easy to manage.
Reporter: How do you manage it?
Deputy Director Dai: Generally, once a month, we spray a nutrient solution once.
The nutrient solution is a specially cultured active agent, diluted with water at a ratio of 1 to 300, and sprayed on the surface of the bed. It can increase the activity of soil microorganisms and accelerate the degradation and digestion of waste. In addition, when you normally notice that pig manure has accumulated in a fairly large amount, spread it toward the empty areas, to facilitate full decomposition.
Deputy Director Dai: There's one more thing. The surface of the bacterial bed must not be too dry. It should stay very loose, but there must not be any dust flying up. Otherwise, the pigs are prone to respiratory diseases.
Stocking density: If too many pigs are raised per unit area, the fermentation state of the bed will decline, and it won't be able to quickly degrade and digest the pig manure and urine. Generally, each pig occupies 1.2 to 1.5 sq m.
Reporter: These past two days, I've found that this technology of ours is indeed quite labor-saving. But, a person like me just wants to spend less money, earn more money, and not put in too much effort. Tell me, is a person like me suited to raising pigs? Help me calculate the economics.
Deputy Director Dai: I think this technology is very suitable for you. Now, let's do the math. First, this kind of pig farming saves a lot of labor. Since there's no need to clean manure, with conventional farming, one person can only raise 500 pigs, but with this, they can raise 1,000. That's a 50% labor saving.
In addition, after the pigs eat the bacteria, their constitution is good, they don't get sick, and basically no medication is needed, saving on medical costs, 1 yuan per pig; also, it can save a portion of the feed, saving 20-30% of feed.
Deputy Director Dai: A particularly important point is water. With conventional farming, a large amount of water is needed for flushing, but with our pig farming, only the water they drink is enough, so a lot of water is saved, saving 90% of water.

He should still find out how many pig farms in China actually use water flushing.
--------------------------------------
How many years can it be used for..............................
--------------------------------------
Under normal circumstances, it can be used for 3-5 years
--------------------------------------
Success comes from the media, failure comes from the media too!!!!!
--------------------------------------
The media is a public service platform. We need to rely on our own eyes to judge the direction of things.
--------------------------------------
The media?????????............
--------------------------------------
This is old news from years ago. Actually, when it comes to how fermentation beds really are, farmers' understanding is different from the media's. This doesn't prove anything. The media isn't professional, and the people they interview are all sellers of bacterial cultures, so it doesn't prove anything either. We should be objective and truth-seeking. There's plenty of material on this, and the cost of building a fermentation bed can be calculated.
Although many people are now promoting fermentation beds, farmers should still keep their eyes wide open to avoid being fooled!!!
--------------------------------------
Whatever you talk about, you have to do; whatever you sell, you have to pitch. Pig farming should be pig-centered. When there's a conflict between people and pigs, people should yield to the pigs!!!
--------------------------------------
Keep your eyes open and work hard!!
