Disease prevention of farmed pigs: how to prevent and cure pig whipworm?

Pig whipworm disease is caused by pig whipworm (Trichurychus suis), also known as Trichurychus suis disease, has long been a common problem affecting the development of pig industry, the following is to introduce the disease prevention of raised pigs: How to prevent pig whipworm disease?

1. Brief introduction of swine whipworm disease

Trichuriasis, also known as Trichuridae, is an endoparasitic disease caused by Trichuridae parasitizing pig caecum. It is widely distributed and can occur all year round. It has been a common problem affecting pig industry for a long time. The disease occurs in pigs raised intensively and in pigs raised freely, especially in some aged and neglected pig farms. Piglets are especially vulnerable to trichuriasis. Serious infections often lead to death. Every year the pig industry suffers huge losses from this disease.

The eggs of Trichuris suis are excreted with feces, and develop into infectious eggs after about 3 weeks. The infection performance lasts for 6 years. Pigs ingest infectious eggs by eating feed, drinking water or digging soil, and they hatch and develop in the small intestine and cecum of pigs. They rob pigs of nutrients, inhibit mucosal immunity of pigs to common bacteria, and cause necrotic proliferative colitis, resulting in pig death.

II. Diagnosis and treatment of swine whipworm disease

When diagnosing whether pigs suffer from whipworm disease from clinical symptoms, it should be distinguished from swine dysentery. If antibiotic treatment is ineffective, combined with pathological changes, it should be considered as whipworm infection. In addition, eggs examination can be carried out for definite diagnosis. Weigh about 10g of sick pig feces, crush them, put appropriate saturated saline, stir well, filter and stand for half an hour, dip the surface liquid film on the slide, cover it for microscopic examination. If a lot of drum-shaped, brownish yellow eggs with egg plugs at both ends are observed, You can confirm whipworm infection.

III. Clinical symptoms of swine whipworm disease

Light infection generally has no obvious symptoms, if parasitism several hundred can appear symptoms, mild anemia, intermittent diarrhea, increasingly thin, rough hair, severe infection (thousands of worms) when depressed spirit, decreased appetite, conjunctiva pale, anemia, stubborn diarrhea, thin feces, sometimes blood or blood, weak body, bow waist hanging abdomen, walking swing, temperature 39.5~40.5℃, drainage before death, bloody feces, with mucus, finally due to breathing difficulties, dehydration, He died of extreme exhaustion.

IV. Prevention of swine whipworm disease

Piglet weaning should be dewormed once, after 1.5~2 months and then dewormed once, do a good job in pen sanitation, regular disinfection or shovel off a layer of topsoil, feces retting fermentation, to eliminate eggs.

5. Treatment of swine whipworm disease

1. Trichlorfon 100mg/kg body weight, mixed feed or irrigation, every 3 days, to seriously ill patients to oral rehydration salts and furazolidone 10mg/kg body weight, once a day, for 2 days.

2. Deinanthrene (thiamizole) 25mg/kg body weight, oral; or prepared into 3%~10% concentration, 15~20mg/kg body weight, intramuscular injection.

3. Albendazole 20mg/kg body weight, oral, 36 hours after the worm can be expelled.

4. Levamisole 7.5mg/kg body weight, po or im.

5. Pyrimidine 2~4mg/kg body weight, dissolved in water and administered orally (injection is prohibited).

The above is the introduction of the prevention and treatment of swine whipworm disease by soil drift net. The method to prevent swine whipworm disease is to do a good job in pig house hygiene, timely deworming treatment, and prevent problems before they occur.
