What are the symptoms and prevention and treatment methods of swine fever?

Swine fever is a highly contagious infectious disease with an extremely high mortality rate, causing countless losses to the pig farming industry in various countries, and even more serious for some pig farms. Although it has gradually been brought under control, it has not been completely eliminated, and the danger still exists. Today, the editor will introduce to you the symptoms of swine fever and its prevention and treatment methods.

1. Current epidemic situation

Apart from North America and Oceania, where swine fever is not prevalent, all other continents and regions have been ravaged by swine fever. At present, swine fever has been brought under control in most countries, with no large-scale outbreaks, and the disease tends to develop more slowly. However, in some local areas, the prevalence of swine fever is still very high; the incidence rate in adult pigs has decreased, while the incidence rate in piglets has increased. The onset period of swine fever is unstable, and outbreaks can occur in all four seasons, generally being especially severe in spring.

2. Reasons for prevalence

The swine fever virus is highly variable, has extremely strong resistance to the immune system, and is difficult to eliminate. Because breeding pigs and piglets, adult pigs and young pigs all live together in the pigsty, it is difficult to find a suitable immunization period when carrying out immunization programs for the herd. The dirty and messy environment of the pigsty leads to the reproduction of the virus, and there is no correct cleaning and operating system. A series of problems such as delayed cleaning and disinfection and lack of attention to sick pigs are all reasons for the spread of the swine fever virus.

3. Symptoms of onset

In the early stage of swine fever onset, the symptoms vary. Some sick pigs are listless, do not eat, their body hair becomes rough, their body temperature rises above 40 degrees, and some even turn pale. Some develop neurological disorders; some have weak limbs, cannot stand, or are lame; some breathe loudly, like to huddle together in groups, have runny noses and sneeze. Some have feces that are both dry and loose, sows miscarry, the feces have a strange odor, and so on. These are all symptoms of swine fever onset.

4. Prevention and treatment

At every change of season, use swine fever blood antibody and Qingwen Baidu San mixed into the feed for half a month continuously for prevention. If sick pigs are found, the sick pigs should be isolated immediately, and iodine preparations should be used to disinfect the herd and the pigsty. Inject sick pigs with a mixed injection of swine fever blood antibody and Boke; add baking soda to drinking water and feed; after the feces return to normal, let the sick pigs drink some multivitamins. At one week, use Juntai Nuo and swine fever blood antibody at the therapeutic dose, and then use the preventive dose for half a month.

Among all pig diseases, swine fever is the most ferocious for pigs, with extremely strong contagiousness. Once a sick pig is found, it must be dealt with promptly; otherwise, the sick pig can infect the entire herd within a week, and the sick pig will also die within 2-3 weeks. Actually, at present, as long as the hygiene of the pigsty and the prevention for the herd are ensured, the possibility of swine fever occurring will be greatly reduced. Try to keep the incidence rate to a minimum.
