The whole-course immune and Health Care Technology of Commercial Pig in its whole Life

In recent years, the incidence of infectious diseases in pigs has increased, the condition is complex, the treatment is difficult, and the mortality rate has increased, especially the highly pathogenic blue ear disease occurred in 2006, which swept half of China in half a year, causing serious losses to China's pig industry, and many farmers lost all their money and lost everything. In this situation of high incidence of epidemic disease, it is very important to do a good job in pig immune health care and prevention, and now many new farmers do not know how to carry out vaccine immunization and drug health care. The following is to talk about: pig vaccine drug immune health care technology.

1. The vaccine injected into sows before mating. In order to prevent the transmission of classical swine fever and blue ear disease in sows and fetuses, sows must be injected with classical swine fever vaccine and inactivated blue ear disease vaccine (containing highly pathogenic blue ear disease vaccine) 2 weeks after breeding. From March to April before summer, sows will be injected with je vaccine before mating.

2. Prenatal vaccination of sows. In order to prevent newborn piglets from infecting pseudorabies, parvovirus, yellow and white dysentery, epidemic diarrhea and transmissible gastroenteritis, pseudorabies inactivated vaccine, K88Mel 99 trivalent or tetravalent inactivated vaccine, epidemic diarrhea and transmissible gastroenteritis vaccine were injected respectively 4 weeks before parturition in sows. Sows born for the first time and less than three births should also be injected with parvovirus inactivated vaccine before pre-delivery. A maximum of 3 vaccines are injected each time, with an interval of 5 mi for 7 days before you can be injected again.

3. Lactating sows: antibiotics should be added to the sow feed for one week before and after delivery, such as florfenomycin + lomefloxacin 1000 grams per ton feed for prevention, or 80% net 125g / ton + chlortetracycline 300g / ton + amoxicillin 150g / ton to reduce the bacteria excreted by sows to pollute the delivery house and cut off the horizontal transmission of disease from sows to piglets.

4. In order to prevent iron deficiency and selenium deficiency in newborn suckling pigs, they should be injected with bovine hemin (0.2ml/ kg body weight) on the 3rd day of birth.

5. "three stitches" health care. In order to prevent piglets from gastroenteritis and respiratory bacterial diseases during lactation, "three needles" health care should be carried out, that is, long-acting oxytetracycline was injected with 0.15-0.2ml/ kg body weight at the age of 3,7 and 21 days, respectively.

6. Piglets at the age of 20 cents and 30 days. Classical swine fever vaccine must be injected at 20 days old, 4 doses per head, and live blue ear disease vaccine and highly pathogenic blue ear disease inactivated vaccine must be injected at 25 days old (preferably strengthened once after 14 days). 30-day-old injection of pseudorabies inactivated vaccine 1ml; if the live vaccine is used, it should be strengthened again after weaning.

7. 1 week before weaning and 4 weeks after weaning, in order to prevent stress and bacterial infection, add doxycycline or florfenicol, 100-125g per ton of feed or 500g of Timi Pioneer 500g for 7 days, rest medicine for 7 days, then use 5rel for 7 days, then use 2mer for 3 times, and electrolyze multi-dimensional drinking water at the same time. In addition, piglets were injected with immunopeptide to enhance their immunity.

8. In order to prevent paratyphoid fever in piglets, oral paratyphoid vaccine can be given to piglets at 35 days of age and once again at 65 days of age. Farms with no epidemic situation or less occurrence can not be used.

9. At the age of 60 days, piglets must be injected with classical swine fever vaccine, 4 parts of cell vaccine and 2 parts of tissue vaccine.

At the age of 10 or 70 days, it is best to inject the combined vaccine of erysipelas and lung disease to prevent the occurrence of lung disease and erysipelas.

At the age of 11, 12 Mel and 13 weeks, add medicine and health care. Amoxicillin 250g, Zhiyuanjing 100g and doxycycline 100g were mixed in 1 ton of feed and used for 2 weeks to prevent bacterial infection. In addition, in order to increase the immunity of piglets, it is also necessary to feed Astragalus polysaccharides for 2 weeks.

At the age of 12 and 17, at the age of 18 weeks, it is also necessary to prevent bacterial infectious diseases, but also similar to the drug health care at the age of 12, 17, 13 weeks. Such as florfenicol 100g, Ailexin 50g, astragalus polysaccharides 200g, electrolytic multi-dimensional mixed in 1 ton feed, continuous use for 2 weeks.

In order to prevent high fever in high fever season, the preventive effect of Jiakang 200g + Antai 500g mixed with 1 ton was good; if the disease was treated, Jiakang 400g + Antai 1000g mixed with 1 ton was given to the whole group, and the drug was used continuously for 2 weeks. At the same time, tylosin + houttuynia cordata injection was injected intramuscularly with 0.2ml/ kg body weight, together with immunopeptide or interferon and antiviral I.

13. No matter big or small pigs, weaned pigs or breeder pigs, they should be vaccinated against foot-and-mouth disease every year when the cold season comes, and they will be injected again in spring, and the vaccine will be supplied free of charge by veterinary stations.

14. Deworming regularly. The worms were dewormed twice at 20Mel 30kg and 50Mel 60kg. Oral ivermectin or intramuscular injection of Shachongding once.

The above more detailed introduction of pigs from the birth of the fetus to fattening and selling, the vaccine, drug, immune and health care to be done in this lifetime, as long as the farm is done strictly, coupled with hygiene and disinfection measures, the incidence of the disease can be greatly reduced or even eliminated, and the industry can develop normally, pork can be supplied normally, pork prices can be stabilized, people can get benefits, and can also contribute to the construction of a harmonious society.
