Immune inoculation

I sent several materials saying that now I am afraid of being fooled, it is difficult to earn forum coins, and so on. I've read other people's files, too. This situation does exist. Now it feels like there are some signs of a massive outbreak. I don't know what to judge. I can only do my own thing. Immunization 1. Types of preventable diseases. Immunization is a very important link in the epidemic prevention system of large-scale pig farms. (1) routine prevention of epidemic diseases, including classical swine fever, swine erysipelas, porcine lung disease, piglet paratyphoid, foot-and-mouth disease, etc. (2) the diseases that must be prevented in breeding pigs: there are mainly viral diseases such as Japanese encephalitis, porcine parvovirus disease, porcine pseudorabies and so on. These diseases mainly cause reproductive disorders of sows and cause a large number of deaths of newborn and weaned piglets. As this kind of epidemic disease is very harmful and there is no possibility of treatment, it is only possible to control its harm by vaccination. (3) selectively preventable diseases: there are mainly porcine Escherichia coli (piglet yellow dysentery, white dysentery, edema disease) piglet red dysentery, porcine streptococcosis, porcine infectious atrophic rhinitis, porcine asthma, porcine transmissible gastroenteritis, porcine epidemic diarrhea, porcine chlamydia trachomatis, porcine transmissible pleuropneumonia and other diseases, which can be vaccinated selectively according to the actual situation of the region and the intestine. 2. Matters needing attention in vaccine application (1) Transportation and storage of vaccine: porcine vaccine can be divided into freeze-dried vaccine and liquid vaccine, and the preservation time of freeze-dried vaccine is shortened with the increase of preservation temperature, which is less than 1 year below-15 and about 6 months at 4MU8. When the temperature is higher, the shorter the preservation time is, the more this kind of vaccine should not be frozen repeatedly and not at high temperature. (2) Vaccine quality: the vacuum degree of freeze-dried vaccine must be checked, and the quality of vacuum-lost vaccine must be decreased. Oil emulsion inactivated vaccine must be fully shaken before use, such as oil emulsion vaccine with oil phase and water phase stratification should be discarded, because although manual shaking is difficult to make antigen and adjuvant fully mixed, some pigs fail to be immunized. (3) the quality of vaccine injection: 1, diluted strictly according to the required method; 2, used within a specified time after dilution; 3. Antibiotics shall not be used in pigs within a specified time after using live vaccine; 4. Strict disinfection of injection equipment and injection site, replacement of needles to prevent cross-infection and iatrogenic transmission. (5) deworming is the same as preventive injection, livestock owners have higher and higher requirements for deworming drugs. The new generation of antibiotic anthelmintic drugs-ivermectin and avermectin not only have a good effect on intestinal parasites, but also have a good killing effect on pig scabies. The insect mites Kexing and Chongmijing produced by the School of Animal Medicine of Huazhong Agricultural University have achieved good results in controlling the harm of internal and external parasites in pig farms. (6) Drug prevention large-scale pig farms can not only use immune injection to prevent and control some infectious diseases, but also give drugs (drinking water, mixed feeding) to related groups at the initial stage of possible disease in pigs. Chuanhuning, as a prophylactic or therapeutic drug, has achieved good results in clinic, specifically 200g (prevention)-400g (treatment) / ton feed for 5rel for 7 days. It has a good effect on the prevention or treatment of respiratory and digestive tract bacterial diseases. (7) Surveillance of epidemic diseases, daily diagnosis and treatment, and epidemic situation eradication may monitor the above diseases. Pig immune procedure (for reference) 1. Sows: before sow mating: 30 days parvovirus inactivated oil vaccine 25 days pseudorabies inactivated vaccine (concentrated) 20 days Japanese encephalitis attenuated freeze-dried vaccine before giving birth to sows: 30 days porcine Escherichia coli vaccine 25 days porcine reproductive and respiratory syndrome live vaccine 2, 1 hour before colostrum for commercial pigs, swine plague rabbit attenuated vaccine Advanced immunization 7-day-old pig atrophic nose (AR) oil emulsion inactivated vaccine 28-day-old classical swine fever rabbit attenuated vaccine 35-day-old porcine infectious pleuropneumonia oil vaccine 40-day-old swine pseudorabies + 60-day-old hog-and-mouth disease genetic engineering vaccine each field can choose to prevent other diseases according to the actual situation of this field. The above is for reference only. -- Immunization is the first point of comprehensive prevention and control measures for animal diseases.
