Symptoms and Control Measures of Swine Ascariasis

Swine ascariasis is a very common disease in some pig farms, and it is not only in China; this disease is epidemic worldwide, and its infectivity is also relatively strong. Generally, infected piglets will show stunted growth, and their body weight drops sharply; in severe cases, they die directly. So what are the symptoms of this disease? How is it prevented and controlled? Below, Shuashuai will explain it to everyone!

I. Onset Symptoms

1. When the larvae of Ascaris suum burrow into the liver and lungs, they cause hemorrhage and necrosis of liver tissue, resulting in ascariasis pneumonia. The pig will cough continuously, breathe faster, and its body temperature will also rise. It will lose all appetite and not want to eat. Usually it just lies motionless on the ground and does not want to move. These are all symptoms after infection.

2. When adult worms travel through the pig's small intestine, they cause abdominal pain in the pig. Moreover, if there are very, very many roundworms, they will gather together and thereby block the intestinal tract, bursting the intestine. If larvae burrow into the bile duct, they will cause bile duct blockage and symptoms of jaundice.

3. Adult roundworms can also secrete a toxin, and this toxin can have a certain effect on the pig's brain, causing some mental symptoms in the pig. In addition, adult worms will absorb a large amount of the pig's nutrients, causing stunted development, stunted growth, and even death.

II. Prevention and Control Measures

1. Drug Deworming

The drugs mixed into feed for feeding include mebendazole, flubendazole, pyrantel, and albendazole; those given by subcutaneous injection or orally include avermectin and ivermectin; and those injected into chickens include doramectin.

2. Preventive Measures

① First, deworming must be carried out regularly. Boars should be dewormed twice a year. Sows should be dewormed once two weeks before farrowing. Deworming should also be carried out once when changing pens, and newly arrived pigs should also be dewormed first when entering the pen.

② In free-range pig farms, piglets after weaning should be dewormed, and dewormed again after one month.

③ The pigpen should be kept hygienic and clean, and the hygiene and safety of feed and water should be maintained.
