Pig farm health care plan should be carried out according to the following steps:

First, the introduction of excellent varieties is the premise and foundation of excellent breeding. Breeding pigs can only ensure the overall peace of the pig farm from the source if they have good production performance and strong disease resistance; Otherwise, it will lay a "curse" for future production.

Second, strictly control feed quality: on the one hand, strictly control the quality of premix; On the other hand, the quality of soybean meal, corn and other bulk raw materials, especially corn, affects the quality of feed to the greatest extent; The quality of feed is directly related to the growth speed and physical strength of pigs. If the nutritional index of feed can not meet the growth needs of pigs, it will directly lead to the decline of immune system defense ability of pigs. As long as the external environment deteriorates slightly, pigs are prone to various diseases. For example, moldy corn can cause reproductive disorders, wig infection and decreased immunity in sows.

When you can buy high-quality raw materials, you must not buy moldy raw materials to save money. "People cheat, pigs don't cheat." Good feed and strong resistance, otherwise it is easy to get sick. When it is inevitable to use moldy feed, we can consider using mold adsorbent to reduce the harm of mold to the body; However, mold adsorbent not only adsorbs mold, but also adsorbs trace components such as drugs in feed, which has great influence on feed nutrition and must be deeply understood.

Third, arrange the necessary disinfection procedures: only by doing a good job in disinfection of pig farms and controlling the pathogen index under the resistance of pigs can pigs be protected from pathogens.

Fourthly, it is almost impossible to make a perfect vaccine immunization plan, especially for virus-related vaccines (such as classical swine fever, blue ear disease, pseudorabies, Japanese encephalitis, parvovirus, etc.). Under the current large-scale circulation environment, it is almost impossible to keep all pathogens negative in pig farms. In this case, we can only improve the pig's own resistance, enhance the pig's specific and non-specific antibodies through various means, resist the infection of various pathogens, and inject.

Fifth, do a good job in drug health care: although all major pig farms can strictly control the above aspects, due to the large circulation and high feeding density, various pathogens are likely to multiply rapidly. In today's breeding environment, it is almost impossible to raise "sterile pigs" because there must be a large number of known and unknown pathogens in the environment, and even many conditional pathogens in pigs. Infection is inevitable.

Infectious diseases usually have three levels, namely recessive infection, subclinical infection and clinical infection. The most ideal way is to control the disease in the stage of recessive infection through drug health care.

At present, respiratory symptoms are the main diseases in various farms. In a considerable number of pig farms, the cost of drug prevention and treatment of respiratory diseases accounts for 70% or even higher of the total drug cost, and the use of drugs for respiratory diseases has almost become a "bottomless pit", which makes the breeding owners miserable. What is the reason for this phenomenon?

According to the investigation, the chief culprit of the above phenomenon is "Circle and Laner", followed by "Pseudorabies and Classical Swine Fever". After the above four viruses are infected, they will all cause respiratory symptoms in pigs. These factors are often ignored by pig farm technicians, so that many times only anti-mycoplasma and bacterial drugs are used for health care, while the combination of antiviral drugs is ignored. In this way, naturally, "the symptoms are well controlled when taking drugs, and will be repeated soon after stopping taking drugs;" The phenomenon of repeated medication and repeated medication. To fundamentally solve this stubborn disease, only by controlling the virus factor.

Because there is no effective vaccine against circovirus at present, and some misleading and unqualified attenuated vaccines for blue ear disease are widely used, the incidence of circovirus and blue ear disease remains high. Both viruses are immunosuppressive viruses, and once they occur, the immune level of most vaccines will be reduced or even ineffective, and often due to immunosuppression, many conditional pathogens may take the opportunity to cause secondary infection.

If you have chronic or recurrent respiratory symptoms in clinic, you can consider the above four virus infections. However, there are no effective antiviral drugs for animals except interferon on the market at present. Although there are products such as Astragalus polysaccharide on the market, it can activate the body to produce interferon in the case of animal disease, which is extremely limited or even minimal. Moreover, the process of stimulating the body to produce interferon needs to consume a lot of body energy, which is no different from the already overwhelmed patients. In order to effectively control respiratory symptoms caused by various viral factors, large-scale farms can choose imported interferon premixes.

Based on the above considerations, we can adopt the following schemes for pig farm health care:

First, do a good job in vaccine immunization (refer to the "Intensive Pig Farm Vaccine Immunization Procedure"): especially the following vaccines.

○ 1, Blue Ear Disease Vaccine: You can choose the "Inactivated Blue Ear Disease Vaccine" produced by Vico Company of Harbin Veterinary Research Institute (the only inactivated blue ear disease vaccine officially approved by the Ministry of Agriculture at present). At present, the domestic attenuated blue ear vaccine has not been certified and approved by the Ministry of Agriculture, which is of poor quality and extremely unreliable safety, and has the harm of detoxification and strong virulence in pigs.

○2. Pseudorabies: You can choose the "Pseudorabies Gene Deletion Vaccine" from Saiwei, Spain or the "Pseudorabies Double Gene Deletion Freeze-dried Vaccine" from Vico Company of Harbin Veterinary Research Institute-the vaccine has a long protection time (the protection time is twice that of imported vaccines, 7 to 8 months) and the antibody level is high.

○3. Classical swine fever: The "zero-free classical swine fever vaccine" (special for advanced immunization) produced by Yongshun, Guangdong is the first choice for super-immunity, and the "classical swine fever spleen-drenching vaccine" produced by Yongshun, Guangdong is the first choice for first and second immunity.

○4.JE: "Freeze-dried Japanese encephalitis vaccine" produced by Yahua, Hunan Province (the only JE vaccine officially approved by the Ministry of Agriculture of China at present) is preferred.

○5. Small: Choose products with the official approval number of the Ministry of Agriculture.

○6. Streptococcus: The "tetravalent inactivated Streptococcus type 2 vaccine" produced by Yongshun, Guangdong is the first choice (the vaccine contains strains C, D, E and II). Streptococcosis broke out in Sichuan in 2005, and the Ministry of Agriculture controlled it with this vaccine, which proved that this vaccine is the best streptococcus vaccine in China at present.

○7. Foot-and-mouth disease: Imported adjuvant vaccine No.5 produced by Lanzhou Veterinary Research Institute is the first choice (the vaccine has fast immune response, high antibody level and long protection period).

○8. Others: such as Haemophilus parasuis vaccine, asthma vaccine, enteritis vaccine, atrophic rhinitis vaccine, pneumonia vaccine vaccine, infectious gastroenteritis-epidemic diarrhea vaccine, etc.

Second, do a good job of insect repellent: every year in spring and autumn, you can choose the imported "ivermectin+fenbendazole" premix (such as "Duochongke" from Yongzhixin, England).

Third, do a good job of disinfection: routine disinfection every week 1 time; High incidence season 1-2 days disinfection 1 time. It is best to use chlorine dioxide (such as "stable chlorine dioxide" produced by Shanghai Kanglide) or glutaraldehyde (such as TH4 disinfectant produced by Sujihua, France) as disinfectant.

Fourth, seasonal prevention of blood protozoa (such as Toxoplasma gondii and Eperythrozoon): especially Toxoplasma gondii.

Summer and autumn are the high season of Toxoplasma gondii, and Toxoplasma gondii is the high season.

① The raw powder of sulfamethoxazole ("Shanshi" brand of Zhejiang Huangyan Veterinary Medicine Factory is the first choice, which has high bioavailability and strong antibacterial activity, and is the first brand of hexamethoxazole in China) can be put into feed once every 1-2 months, lasting for 7 days; (Cost: 165 yuan/ton of feed)

② Su Fosun (Compound Six -A, produced by Zhejiang Huangyan Veterinary Medicine Factory) can be fed with complete feed once every 65,438+0-2 months, and the product can be added with drugs to relieve respiratory symptoms on the basis of maintaining its excellent quality; The effect is better than the original powder, the cost is lower than the original powder, and the side effect is small): 1000g/T, seven days. (Cost: 120 yuan/ton of feed)

Fifth, improve the feeding environment and enhance physical fitness.

Harmful pathogenic microorganisms inevitably exist in any farm, and a large number of beneficial microorganisms are born with pathogenic microorganisms. In general, the two are in a dynamic balance; When pathogenic harmful microorganisms invade, harmful microorganisms multiply in large numbers, and the living space of beneficial microorganisms is seriously inhibited, and the above dynamic balance is broken. In this way, animals with low immunity or animals under stress are the first to be infected quickly, and pathogenic microorganisms multiply rapidly in these sick animals, becoming a de facto pathogenic microorganism culture bank. When pathogenic microorganisms proliferate to a certain number, healthy animals with strong immunity will also be infected.

How can we avoid the above situation? We can start from the following aspects:

1, supplement a large number of beneficial microorganisms, and let the pathogenic harmful microorganisms "have nowhere to hide" by letting "beneficial microorganisms" compete for the living space of "harmful microorganisms"; This kind of product has been supplied in the market for a long time, but the widespread use of antibiotics in premix seriously restricts the use of this kind of product. If the antagonism between "beneficial microbial agents" and "antibacterial drugs" can be solved technically, this method is promising before antibiotics are completely replaced. In the European Union, four kinds of antibiotics that were originally allowed were also cancelled. Facts have proved that pigs can not only be raised without antibiotics, but also be raised better.

2. Improve the digestion and absorption rate of feed and enhance animal physique: Why do pigs raised with the same formula have such a big difference in disease resistance? The key lies in the digestion and absorption rate of feed by different animals, which seems to be the same. Animals with poor digestion and absorption ability are naturally weak.

To improve the digestion and absorption of animals, we can use high-quality enzyme preparations and supplement digestive enzymes by exogenous sources to achieve this goal.

Suggested use: 1, a "live bacterial enzyme" produced by Korea Central Biotechnology Company, has both "live bacteria" and "enzyme", which technically solves the antagonistic problem between "beneficial microbial preparation" and "antibacterial agent". Dosage: 0.5- 1.5㎏/ ton of full-price material. 2. "Livestock and poultry ecological treasure" produced by Wuhan Huayang, dosage:1/ton full price material.

Six, common drug health care:

Drugs are only temporary exogenous interventions when the body is sick. It is impossible to stop taking medicine after all, whether it is for ten days or half a month. Once the drug is stopped, the body still relies on its own resistance to resist the invasion of external pathogens. Strong resistance comes from the absorption of nutrients, which drugs can't achieve. Therefore, the concept of relying on drugs for reproduction is completely wrong, and drugs are not allowed. What we want is not how to help animals treat diseases, but how to reduce diseases.
