Seven sets of interviews with professional pig farmers in fermentation beds

CCTV interviewed professional pig farmers in the fermentation bed reporter: Yo, strange, this pigsty has no smell. When I passed those pigsty just now, I smelled the indescribable smell far away. What's going on? I'll find someone to ask. Director Chen: this kind of breeding is a new method, which is called pig breeding in fermentation bed. Reporter: the method of raising pigs in fermentation bed? Director Chen: yes. Reporter: what is the difference between this technology and our previous methods of raising pigs? Director Chen: originally, in the traditional method of raising pigs, the urine and urine of the pigs were all inside. After the water was washed, they rushed outside, causing pollution to the environment. Our factory, uh, was listed as a time limit rectification unit by the Zhenjiang Municipal people's Government. But now, with this technology, the environment has been well protected. In addition, the quality of the pig has also been improved, and the price of meat has also been sold high. Oh, Lao Wang sells melons and boasts. Is this skill really that good? ask a worker. Reporter: young man, let's use this fermentation bed to raise pigs. How about raising pigs now? Worker: with this kind of skill, we workers will save trouble. Reporter: how to save trouble worker: pig feces, urine, we do not need to deal with, we can add materials. If I hadn't seen it with my own eyes, I couldn't believe that pig farming didn't have to clean up pig droppings, which would have saved a lot of trouble, but Wenwei wondered that the pig was eating, drinking and spreading in the circle, but why was it neither smelly nor dirty in the circle? it was hot and there were no flies flying. Reporter: I never thought that I would still sit in the pigsty and chat all my life. This is the place where the technology was introduced. I would like to ask, what on earth is wrong with this technology? Shen: this fermentation bed raises pigs, just like the name. It uses organic padding to build a fermentation bed, uses the fermentation bed to absorb its feces, and uses the microorganisms in this fermentation bed to decompose the feces and convert feed. When the feces are decomposed, the natural smell is gone. it turns out that this is all the work of microbes. Director Shen and their experiments found that in only three days, the feces were broken down into very fine powders by microbes and disappeared without a trace. At the same time, feces provide nutrition to fungi, and beneficial bacteria continue to multiply to form hyphae. These high-protein substances have become a delicacy for pigs, which can not only help digestion, but also improve immunity. The whole fermentation bed forms a perfect small "biosphere", which can be said to be zero-emission, pollution-free organic agriculture. Shen: look at this bed. It's loose, soft and not smelly. Interviewer: it's dry. Sunken place: like sand. Interviewer: let me smell it. Shen: is it smelly? Reporter: it doesn't stink, it smells like dirt. Sunken place: there is a little smell of soil microbes, no foul smell of feces. Reporter: how thick is this? Shen: the thickness is about 80 to 90 centimeters. Interviewer: I find it very hot here. Shen: yes, the next fermentation is under way. Interviewer: yeah, it's hot. Sinking place: the process of fermentation is heating. After the fever, a large amount of water in the material is evaporated, and the smell is decomposed by microorganisms, so the bed is very clean. Interviewer: that's why we can sit here and talk about the sink: so that we can sit here without getting dirty on our buttocks. The pig raised in the fermentation bed returned to the "native" environment, and he was in a good mood and did not recognize his birth. As soon as Wenwei came, he came to visit, untied his shoelaces, and was busy tickling him. The pigs are in a good mood, their appetite is good, their bodies are good, and they smell good when they have nothing to eat. They run happily when they have nothing to do, each with shiny fur and tendons. My colleague Wen Wei learned something after spending most of the happy day with the pigs. Reporter: I found that this mattress has three functions. First, trampoline reporter: second, Simmons reporter: third, electric mattress, look how beautiful it is! Reporter: the mattress was very interesting just now. What material is it? sinking place: well, we just built a new one. I'll show you how it is. The material of this fermentation bed is mainly sawdust, and in addition, it is clean soil and salt. well, the soil requires clean soil that has not used chemical fertilizers and pesticides, because there are more microbes in it. In addition, salt, use crude salt. The cushion is mainly composed of sawdust, accounting for 90%, and the other 10% is soil and a small amount of salt. Sawdust is very soft and can absorb water; adding coarse salt is beneficial to the decomposition of sawdust. Reporter: OK, now that the bedding of our fermentation bed is ready, I should take the last step and the most critical step, that is, to spread these bacteria evenly into this fermentation bed, this strain, see what kind of things, and smell it again, there is a taste of steamed bread after it is sour. Just now the sinking place told me that this strain was collected from the soil. And then put it in the laboratory and cultivate it, and that's what happened. Now I'm going to spread these bacteria well and evenly, and start working. Mix the bacteria and bedding well, ferment for 4 or 5 days, and the pig can go to bed. Interviewer: what about the height of our mattress? Director Chen: the height is generally 80 cm to 90 cm. In the south, where the groundwater level is relatively high, we usually use the above-ground type. If in the north, the groundwater level is relatively low, we can use the underground type. The height is the same, 80 to 90 cm. Pigs in captivity should be thoroughly cleared of parasites in advance. Whether the fermentation bed is easy to use or not also has something to do with the construction of pig houses. Generally, piggery is required to sit south and north. This kind of enclosure has good lighting and is conducive to fermentation. Moreover, it is well ventilated and has no stink or mosquitoes and flies. If it is raised in a greenhouse, it will save both trouble and money. Because the greenhouse cost is low, and the microclimate is easier to adjust. With good lighting and warmth in winter, pigs can survive the winter safely; in summer, put down the sunshade film and shake the skirt around to ventilate and cool down. Reporter: I also found that this soil seems to be a little darker than the one I saw just now. Acting director: as for this pig, it has been raised for two years, and the sawdust has been decomposed by this indigenous bacteria, so this color is brown. Experts say that not only pig feces and urine never need to be cleaned, but also the cushion of the fermentation bed, which does not need to be changed for 10 or 20 years. Do you think it is hard to find such a good thing with lanterns? However, Wen Wei still has a worry. Reporter: is the mattress like this easy to manage? Acting director: good management, good management. Reporter: how to manage it? Acting director: in general, we spray nutrient solution once a month. Nutrient solution is a specially cultivated active agent, mixed with water according to the ratio of 1: 300 and sprayed on the bed can improve the vitality of soil microorganisms and speed up the degradation and digestion of excreta. In addition, it is usually found that pig feces accumulate more, sprinkle it to the open space to facilitate full decomposition. Acting director: in addition, the surface of the bacterial bed should not be too dry, that is, it should be kept loose, but there should be no dust, otherwise, pigs would be prone to respiratory disease. Feeding density: if there are too many pigs per unit area, the fermentation state of the bed will be reduced, and the feces and urine of pigs can not be degraded and digested rapidly. generally, each pig covers an area of 1.2 square meters and 1.5 square meters. Reporter: over the past two days, I have found that our technology is indeed quite convenient, but, like me, I just want to spend less money, have to earn more money, and do not want to make too much effort. Do you think people like me are suitable for raising pigs? help me calculate an economic account director: I think this technology is very suitable for you, so now do an account, first, this kind of pig farming is very labor-saving, because there is no need to clean up dung. If it is routinely raised, it means that a person can only raise 1000, and it can save 50% of the labor. In addition, after eating bacteria, pigs have a good physique, do not get sick, basically do not use medicine, save medical expenses, one yuan per pig; in addition, they can also save part of the feed and save 20% of the feed. Acting director: one of the most important is water. If we raise pigs routinely, we need a lot of water to wash, but if we raise pigs, as long as we eat enough water, so we save a lot of water, saving 90% of water. Acting director: one of the most important items is water. if we raise pigs routinely, we need a lot of water to wash, but if we raise pigs, as long as we eat enough water, so we save a lot of water, saving 90% of water. He'd better find out how many pig farms in China are washed with water-they can last for several years. no, no, no. -- under normal circumstances, it can be used for 3-5 years-- Cheng Ye Media, failure also Media! -- the media is a platform for public service. We have to judge the direction of things by our own naked eyes. The media? In fact, what about the fermentation bed? the understanding of the farmers is different from that of the media, which is not a problem. The media is not a professional, and the interviews all sell bacteria, which does not mean anything. To be objective and realistic, there are a lot of information in this respect, and the cost of building a fermentation bed can be calculated. Although many people are stirring up the fermentation bed now, we still need to ask the vast number of farmers to open their eyes so as not to be fooled!-- you have to do what you say and shout what you sell. Pig-raising is pig-oriented, and people should obey pigs in the conflict between people and pigs! Open your eyes and work hard! Director Chen: originally, in the traditional method of raising pigs, the urine and urine of the pigs were all inside. As soon as the water washed, they rushed out, causing pollution to the environment. Our factory, uh, was listed as a time limit rectification unit by the Zhenjiang Municipal people's Government. But now, with this technology, uh, This environment is well protected, and in addition-- but some people do not ferment this method very well. Don't know what the problem is?
