What types of vaccines are commonly used in pig farms?

The pig farming industry is currently an industry strongly supported by the state, and now the National Food Safety and Quality Supervision Bureau has also stepped up supervision of pork. Pork from diseased pigs and pork that fails to meet quality standards due to other factors cannot be sold, and in the process of raising pigs, some common diseases inevitably occur, so pig farms often keep some preventive and treatment agents on hand. Below are several of the most commonly used vaccines in pig farms compiled by Qinnong Network. Let's take a look.

1. Blue ear disease vaccine

The incidence of blue ear disease in pig farms is very high. It mainly contaminates the farm environment and feed through feces, saliva, and other means, thereby causing respiratory diseases. It is highly contagious, so we must strengthen daily management and clean the pig farm in a timely manner. At present, there is no specific drug for blue ear disease, so pig farms commonly keep live vaccines and inactivated vaccines on hand, because the efficacy is somewhat better when these two vaccines are used in combination; using only one type alone takes effect very slowly.

2. Pseudorabies vaccine

Pseudorabies is an acute infectious disease. It can cause sows to miscarry or the piglets they give birth to to be stillborn, boars to lose sexual ability, and if piglets contract the disease, they will die in large numbers, so the losses to farmers are severe. The probability of this disease occurring in pig herds is very high, so farmers must keep preventive vaccines on hand. There are usually two types of vaccines: inactivated vaccines and attenuated vaccines.

3. Foot-and-mouth disease vaccine

Foot-and-mouth disease is actually what we often call mouth disease. It is an acute infectious disease. Many animals often suffer from this disease. Foot-and-mouth disease is mainly caused through the digestive tract, and it is also related to the feed used for raising them. We usually keep inactivated vaccines on the farm and inject the vaccine behind the ear root according to boars, sows, piglets, and their growth stages to achieve a preventive effect.

4. Classical swine fever attenuated vaccine

Classical swine fever is a disease with very strong infectivity and very fast transmission. Recently, classical swine fever has occurred in many areas, causing great losses to farmers, and recently a type of African swine fever has also appeared, so we need to strengthen management and preventive measures. For classical swine fever, pig farms generally keep attenuated live vaccines on hand and inject them at different growth stages for prevention.

5. Red dysentery vaccine

Red dysentery mainly occurs in piglets, especially newly weaned piglets, which are most prone to red dysentery. The main reason is that they need a process of adapting to new things, and some piglets with weaker constitutions cannot adapt to the new food for a time, resulting in diarrhea, and after prolonged diarrhea, red blood streaks appear in the feces. If not treated in time, it can also cause death. For red dysentery, pig farms commonly keep oxytetracycline on hand for prevention and treatment. At the same time, Clostridium welchii type C can also be used for injection.
