Does echinococcosis occur in all seasons? Porcine hydatidosis is caused by the larvae of the echinococcosis, the echinococcosis, and is a global zoonotic parasitic disease. It has a high incidence and a wide range of epidemics in China. Adults of Echinococcus granulosus mainly live in the small intestine of dogs, wolves and foxes. The larvae are parasitic in the liver, lungs and other organs of humans and cattle, sheep and pigs, which seriously endanger people's health and the development of animal husbandry.
I. Overview of echinococcosis in pigs
1. Porcine hydatid disease occurs all year round, and pigs of no age can infect pig hydatidosis.
2, the lifelong host of the hydatid is a dog, the egg section excreted with the feces to pollute the environment, and after being swallowed by pigs, it will be infected with hydatidosis, and the hydatid will parasitize in the liver, lungs and other organs.
3, the parasitic pig, in the process of death slaughter, will find that the pig's liver is slightly larger or normal, the liver surface is uneven, there are a number of different sizes of broad white or yellow round, such as broad beans, soybeans, walnuts, etc. Oval echinococcosis vesicles. The vesicles are firmly bonded to the surrounding liver tissue and are not easily peeled off. There is an inflammatory red or bleeding area around the wall of the capsule. After the incision, the honeycomb is filled with a colorless or light yellow transparent liquid.
Second, pig hydatid disease prevention and control measures
1, prevention
From the above we can know that the lifelong host of Echinococcus granulosus is a dog, which mainly invades the liver of pigs and reduces the normal function of the liver. Therefore, any carcass and viscera after slaughter must be discarded and burned when it is found. Feed the dog. At the same time, it is necessary to strengthen the management of the farm dog, regularly deworming the pig, and pay attention to the isolation and tying of the dog during the deworming period (23 days after taking the medicine).
2, deworming
(1) Praziquantel: The amount of the dog is 510 mg per kilogram of body weight once orally, and the insects are dewormed once a month. The amount of pig used was 2,540 mg per kilogram of body weight, once orally, for two days.
(2) Arecaline Hydrobromide: The amount of dog is 1 mg per kilogram of body weight, once orally.
