Pollution Change of Ecological Environment and Rampaging of Pig Disease

In recent years, various pig infectious diseases have dealt a devastating blow to the pig industry across the country, making many pig farms bankrupt several times. Today, with the rapid development of modern medical science, medicine has no effect on some infectious diseases. This makes us have to think deeply, how can there be so many infectious diseases a few decades ago, when pigs ate except bran vegetables and swill, lived in smelly water circles, but could hardly have any diseases. Today's pigs eat corn bean cakes vitamins, live in high-end pig houses, and inject and disinfect them every day, which is higher than the lives of some people, but they can get all kinds of diseases, and they can't be cured. Live and eat better but get sick, soak in the smelly puddle, eat bran vegetables and drink stinky water but not sick. What does this mean? it's not worth thinking about. I think this is all caused by our human beings destroying the environment and changing the ecological biological chain. although we use anti-inflammatory drugs, fungicides and disinfectants every day to kill the disease-causing bacteria, we can also kill all the beneficial bacteria, so that the disease-causing bacteria have no natural enemies. This is the same as where rat poison was sold everywhere a few years ago. at that time, even in the wild, the field was full of rats and ate all the seeds they had just planted. Later, there was no rat poison, but there were fewer rats in some places, and there were more cats as the natural enemies of rats. Everything in nature has a biological chain, cats eat mice this is the biological chain, pigs eat shit and dirt, the bacteria in the dirt compete with the pathogenic bacteria of pigs, this is also the biological chain, you break the biological chain, the biological chain of bacteria and germs is not balanced. Virus bacteria have no natural enemies to compete with, and our drugs alone are not good enough to do a lot of harm to pigs. The habit of pigs is to live in an environment of dirt, where beneficial bacteria live in harmony with pigs and pigs, and pigs and beneficial bacteria compete with pathogenic bacteria. We have changed the living environment of pigs. Pigs' good friends have lost their beneficial bacteria, so it is impossible for pigs to compete with virus bacteria alone. Another thing is that our medical research has failed to keep up with the development of germs and viruses, which is why we are in today's situation. I think this is the first thing we should consider. This is my point of view. Welcome friends who are interested to study together. The author-- the blogger, the biogas researcher-- is great.
