Jump out of the pig disease prevention ring for healthy breeding

In recent years, we have entered a vicious circle in the prevention and control of swine diseases, that is, more and more types of vaccines and veterinary drugs have become more and more high-grade, from domestic to imported, but more and more pig diseases have been introduced. More and more complex, more and more difficult to cure. In the case of the blue ear disease, the first few pig farms introduced the disease, which caused a great loss to production. Since the domestic vaccines and imported vaccines were listed, the overwhelming application of prevention has not only prevented them but has led to national The upper and lower blues; the highly pathogenic blue ear caused by a variant strain swept across the country from south to north. The use of antibiotics is even more so, and it is continually being replaced. Even the antibiotics used by humans are also used by pigs. Not only is the pig disease not controlled, even people do not dare to eat meat. We have to sit and think about it. Why? The price of pigs this year is so high that raising pigs will not be able to come up. The current price of “three foreign yuan” pigs has been as high as RMB 16/kg or more, but some pig farmers are still losing money. Many farmers want to raise them and still dare to raise them. The threat is still difficult to control pig diseases. Is it really difficult to control pig disease? I did some research and I feel that the main reason is that the concept of raising pigs is wrong. Laizhou City Lean Hog ​​Research Institute (an individual farm), old pigs in the 1970s, was responsible for the breeding of black pigs in Yantai. It has been raising pigs for more than 30 years. The herd is stable, and the birth rate is the highest in the country. The head stocking sow provides more than 22 bred pigs each year. The vaccine is used only for swine fever, foot-and-mouth disease, pseudo-rabies, and antibacterial drugs are rarely used. In the words of Liu’s own manager, I know that my own pig does not have these new diseases. The most important thing is to make a good outsourcing pig, and do a good job of isolation and adaptation of imported pigs.

For most of our farms, what kind of vaccine is used for what kind of vaccine, what new drugs will be used, and the more disease prevention is. It is said that the vaccine is a disease-preventing one, and it is safe to use it. What if there is a problem? As everyone knows that the vaccine is a double-edged sword (the detailed discussion on the "Virulous disease against pigs" in the 9th expert forum in 2007), the injection of vaccine can stimulate the body to produce antibodies, which is a great stress to the animals. It is necessary to mobilize the body's immune tissue and memory cells to digest large amounts of body proteins to produce antibodies. It is easy for the boar to be in a sub-health state, a critical period of pregnancy, and a boar being used. Inactivated vaccines have large stress and slow antibody production. Some adjuvants also lead to the production of circovirus; live vaccines are used without attention, which can easily cause virus spread and virus mutation. Some attenuated virus vaccines are not well handled and are easy to inoculate other viruses. Huge economic loss. Therefore, the epidemic prevention procedures must be formulated in accordance with the situation on the site, and some should be lost. Do not visit the temple for visits, and you must not change the vaccine at will (see “Warning of the Improper Use of the Blue-eared Disease Vaccine, 2007”). I am very interested in the current natural pig raising law and the trials of healthy pigs and non-resistance feeds received in this journal. I no longer add antibiotics in the feed, and use yeasts and other beneficial microbial flora to keep pigs. The digestion and absorption in the best condition. Additives like peptides, polysaccharides, proteases, organic acids, and organic trace elements, such as those produced in Taiwan, can increase the immunity of pigs, promote digestion and absorption of feed nutrition, make pigs healthier, and increase weight gain. , survival rate, reproduction rate increase. In this way, raising pigs not only has a high level of production, but also has no drug residues in the pig itself. The health of the pigs is disease-free and the pork is safe. The reports in this area are being published one after another. I hope that you will jump out of the cycle in epidemic prevention and control and try to raise the pigs happy. Experience will provide consumers with no anti-pork happiness.
