Scale pig farm infectious disease prevention

1. Foot and mouth disease

Relevant animal medical experts tested the herds of foot-and-mouth disease symptoms that occurred in many places in China this year. The detection was variability of foot-and-mouth disease, symptoms of pigs, blisters in mouth, hoof, breasts, etc., causing pigs to be painful and difficult to eat. The appetite is reduced, which causes the body's resistance to decline. In the end, the body is thin, and the pigs whose appetite is abolished will only slowly die. The pigs with strong body resistance will only slowly heal themselves. In general, the infection rate of the pigs Very high, but the mortality rate is not high, but it has caused double cost waste, drug waste, waste of feed, prolonged feeding cycle and increased breeding cost.

Prevention: People generally take vaccination, drug prevention and treatment. But the final result is not ideal. Uninfected farms should strengthen the nutrition of the herd and strengthen the movement of the herd, thus improving the overall body resistance of the herd. However, for large-scale pig farms, the feed formula that has been studied has been difficult to change, so large-scale pig farms are difficult to prevent foot-and-mouth disease.

2, porcine transmissible gastroenteritis

Porcine transmissible gastroenteritis is a highly contact, infectious intestinal disease caused by porcine transmissible gastroenteritis virus. This pig disease occurs mostly in the late winter and early spring, and spreads very quickly. In the same epidemic area, all pigs can be infected. Piglets under 2-3 weeks of age will die in large numbers. After 5 weeks of age, the mortality rate of pigs is very high. low.

Symptoms: The suckling pigs suddenly develop, the sputum is yellow watery, sometimes it sheds white dilute containing curd block, vomiting, rapid dehydration, quickly losing weight, severe thirst, loss of appetite or abolishment. Mortality decreases with increasing age.

The growth period of pigs and sows varies in severity and is usually limited to anorexia and diarrhea for one to several days. Individual pigs vomit and their abdominal circumference increases. Some sick sows have elevated body temperature, no milk, anorexia and diarrhea.

Treatment: Infectious gastroenteritis in pigs is easy to cause group infection, difficult to control, so it is very difficult to treat, the mortality rate of infectious gastrointestinal inflammation is not lower than foot-and-mouth disease, treating porcine transmissible gastroenteritis, first of all Pigs are fasted and usually fasted for 2-3 days. However, during this period, 30-50 grams of "oral rehydration salt" should be dissolved in 1000 ml of warm water to allow pigs to drink. Then combined with the following drugs, you can receive satisfactory results.

Intravenous injection of interferon inducer - 2-4 ml of polymyocytes, once a day.
