Using fermentation bed to raise pigs has less disease.

Take the dynamic microecological pig raising technology as an example, the stress and incidence of pigs are very little, which is similar to the semi-stocking state and extensive management, which is the premise of successful entrepreneurship.

This is the topic that friends who are first involved in the pig industry are most concerned about, and it is also the most worrying issue for friends who are new to the pig industry.

Why is it difficult to raise pigs now? why is the disease of pigs becoming more and more frequent and more and more difficult to treat?

With the development of the pig industry, more and more pig breeds have been introduced into our country, and there are many kinds of pig breeds. As there were no unified laws and regulations on the import of pig breeds, anyone who has money can go to foreign pig breeding farms to introduce breeding pigs. Therefore, from the beginning of the import of the first breeding pig, the hidden danger of uncontrollable epidemic disease has been buried, and the result of blindly introducing breeding pigs for many years is Cause China's unique pig farming: "all countries disease" the complexity of Chinese pig disease, the introduction of credit is indispensable. "introduction of pigs from all over the world, with diseases of all countries" is an appropriate evaluation of the introduction of pigs in China, American, Danish and British. Changbai, Da Bai, Sig, Duroc. Almost all breeds and strains of breeding pigs in the world can be found in China, and almost all pig diseases can be found in China. From the outbreak of streptococcosis in southwest China and the highly pathogenic blue ear disease sweeping the country in previous years, almost all can be attributed to this introduction system. This is also one of the most fundamental reasons why pig disease is becoming more and more frequent.

The large piglet trading market model formed many years ago in China was very popular for a time, which not only brought great development to China's pig industry, but also allowed all kinds of diseases to spread to the north and south of the Yangtze River, even under the current self-breeding mode, in order to pursue high profits, the use of high input, high output, high-density feeding mode, so that viruses and bacteria have a breeding hotbed, desperately use large doses of antibiotics While causing residues in meat, it has also caused a common phenomenon that pig disease is difficult to treat. we know that in the 1980s and 1990s, pigs with colds and fever could be cured simply by pulling a few herbs, but now it is no longer possible, and it is useless to spend a lot of time injecting and taking medicine.

In recent years, there has been a large outbreak of porcine circovirus in intensive pig breeding areas such as Taiwan Province and Guangdong, and pigs are covered with red ugly red spots, resulting in a decline in pig immunity and difficult to sell. However, there are few or no skin diseases including circovirus in the fermentation bed.

What is the stress response of pigs, why should we pay attention to the stress response of pigs, ignore what serious consequences they will have.

The drug resistance of pig pathogens and viruses is getting stronger and stronger, and it is difficult to prevent the emergence of variant strains, while the stress response of improved breeds of pigs (commonly known as three-yuan pigs, four-yuan pigs and lean pigs) is much greater than that of native pigs. it is impossible to give up imported pig breeds in China (imported pig breeds have high lean meat rate, low feed-to-meat ratio and fast growth rate, which is the premise of ensuring our national pork consumption. The result of abuse of antibiotics and stress in pigs is continuous endogenous infection and double infection, resulting in secondary infection. A small stress response, if not paid attention to, may also lead to the destruction of the whole field.

What is stress response? In the final analysis, stress is "not adapted", what situation will cause stress? It can be said that any changes and use of environment, feed, drugs, etc., can cause stress reactions, such as weaning stress of piglets, piglets leaving sows and feeding on solid feed, changing pig pens, piglets will have stress reactions, that is, piglets weaning stress syndrome, which is characterized by: frantic restlessness in the first two days after weaning, calling for a mother, then it becomes quiet, the abdomen is sunken, and the fur is loose a few days later. Standing still, weak limbs, walking and shaking, like lying, afraid of cold, normal or slightly low body temperature, empty chewing, no interest in feed, some thirsty, like to suck the belly of other pigs. Some have diarrhea, extreme emaciation, and eventually die of exhaustion. The main manifestation is a post-weaning hunger strike. Piglets can also stimulate endogenous circovirus (PCV2) due to sudden changes in weather (such as changeable weather in spring), which can cause multi-system failure syndrome in piglets, which is very difficult to treat and can only be prevented.

Other stress reactions include piglet transportation, sudden weather change, feed change, injection response, column change, artificial drive, beating and scolding, abnormal noise, mosquito and fly bites. And so on, and the most important stress is: "psychological stress" (which will be introduced later). At the beginning, stress may only be a small reaction, leading to minor diseases such as cold and fever, but because of the wide variety of pig diseases in our country, frequent variation, complex introduction, complex endogenous viruses and bacteria, it often leads to secondary diseases, which are constantly aggravated and difficult to control. In the end, it may change from small to big, or even be wiped out. It's all possible.
