Parasitic diseases are the object of our need to focus on prevention and control in the process of raising pigs, after the occurrence of parasites in pigs, there will be a decrease in appetite, emaciation, loss of fat and other phenomena, which will have a great impact on the health of pigs and the cost of breeding. So what are the parasitic diseases in pigs? And how to prevent it?
What are swine parasitic diseases?
1. Ascariasis: caused by swine roundworm parasitism in the small intestine of pigs, which has a high infection rate, strong fecundity and high infection intensity. The harm after pig infection: first, the migration of larvae can lead to mechanical damage to pig internal organs and cause pneumonia; second, to seize the nutrition of the pig, resulting in anemia and weight loss in the pig; third, the parasitic stimulation of the insect body causes enteritis diarrhea; fourth, the insect toxin causes the pig body to reduce the resistance, secondary to other diseases, and eventually lead to death. This disease is the most harmful parasitic disease in pigs.
What happens to the itching and peeling of pigs? What are the common parasites in pig farms and how to deworm them effectively
2. Lung nematode disease. It is caused by lung nematodes parasitizing the pig bronchi and bronchiole, mild infection with strong paroxysmal cough, which can cause pneumonia, dyspnea after exercise and feeding, anemia and emaciation in sick pigs, and finally weaken and die.
3. Gastric roundworm disease. It is caused by gastric roundworm parasitism in the mucosa of the pig's stomach. When the pig resistance is strong and the number of insect parasites is small, no abnormality is seen; when the pig is weak, the resistance is poor or the insects are parasitic in large quantities, the mechanical stimulation of the insect body can cause gastritis, the spirit of the sick pig is poor, anemia, emaciation, dysplasia, and mixed blood black stool.
4. Echinococcus disease. Echinococcus parasitizes the small intestine of pigs caused by the body of the annotonic process firmly inhaled into the mucous membrane of the small intestine, mechanical damage to the nostril hook can cause enteritis, necrosis and ulceration, and when the pig is seriously infected, symptoms such as loss of appetite, diarrhea, bloody stool, abdominal pain and other symptoms are obvious, which can lead to intestinal perforation, peritonitis, and intestinal adhesions.
5. Ginger flakes fluke disease. It is caused by the parasitism of ginger flakes in the small intestine of pigs, mainly due to the mechanical damage of the intestinal mucosa adsorption by the insect body, seizing nutrients and toxins and causing disease. Severe infection can cause stubborn diarrhea, progressive wasting, loss of appetite, indigestion and other symptoms in sick pigs.
6. Scabies mite disease. Scabies mite parasitism is caused by the skin of the head, neck, shoulders and legs of pigs, the disease has a strong contagiousness, the insect body in the parasite under the skin to dig tunnels, spawn and reproduce, causing sick pigs to itch and bite the railing. Can cause a lot of economic losses.
7. Blood lice. It is mostly parasitic in the folds of the skin of the neck, ears, ribs, inner legs and abdomen of pigs. Blood lice make pigs restless and grow slowly.
1. It is recommended to self-breed and self-support
It is recommended that pig farms breed and raise themselves, such as the introduction of pigs from other places, should adopt a full-in and all-out breeding method to prevent the introduction of parasitic diseases. When it is really necessary to purchase live pigs, they should be purchased from places without epidemics, and the quarantine certificate should be checked before purchasing. Purchased pigs are kept in isolation for more than 2 weeks and their feces are checked to determine whether they have parasites. If the disease is found, it is necessary to deworm 1 to 2 times and do another examination, and after comprehensive testing to confirm that there is no disease, it can be transferred to the production area.
2. Formulate prevention and control plans
Pig farms shall, under the guidance of veterinarians, formulate parasitic control procedures according to the epidemic situation and law of parasitic diseases in the region or the farm, the medical history of the pig farm, and the breed, day age and feeding management of pigs. Locally raised hogs can be dewormed twice a year at the right time. The prevention and control of parasitic diseases should be regularized and institutionalized. Do a good job of parasite monitoring before deworming in large-scale pig farms, and use the monitoring results as the basis for deworming.
3. Environmental disinfection
The keeper's clothes and utensils are heated and disinfected; the pens and transport vehicles are sprayed and disinfected. Immature eggs have weak resistance to dry, high-temperature environments, and the pig house should use a concrete circle surface, and the pen should be sunny.
4. Do a good job of regular testing
Large-scale pig farms should regularly test pigs for parasitic diseases, and breeders should also conduct regular tests or health checks to monitor the infection of pig parasites at different stages and periods.
Treatment and prevention: choose a new, broad-spectrum, efficient, safe, and can simultaneously expel the porcine parasites. Because simple ivermectin and avermectin have a good effect on repelling parasites such as scabies mites, and have a poor effect on larvae such as roundworms and hairy nematodes in the migration period of pigs, while albendazole has a strong repellent effect on nematodes, trematodes, coccidioides and their migratory larvae and tapeworms, and has a strong inhibitory effect on the hatching of insect eggs, compound anthelmintic drugs should be used for deworming.
<h1 class = "pgc-h-arrow-right" > "deworming dispersion", the main components are ivermectin, fenbendazole, imported intestinal mucosal repair agents and complex enzymes. </h1>
Summary: We must pay more attention to the status of the pig herd in the feeding process, provide a comfortable and healthy environment for them, do a good job in epidemic prevention, and ensure the nutritional hygiene of the feed diet in order to exert their best production benefits. The health of sows is the foundation and fundamental of the health of the pig herd, and solving the above problems seriously affects the efficiency of pig farms, many pig farms try to solve them by means of antibiotics and vaccine immunization, but the practice of several years has confirmed that the effect is mostly not ideal.
We must reasonably match the feed in the pig raising process, provide clean and sufficient drinking water, properly enhance the movement of the sow, and add some vitamins to the feed "quick supplement 21" and probiotic "stomach power" to maintain the health of the sow's digestive system.
