When it comes to the topic of parasites in pig farms, it is inevitable that people will feel a bit "diaphragm", and the harm of parasites to pigs is as small as causing skin diseases and causing pigs to die of exhaustion. Farm parasites are divided into two main categories: in vivo parasites and in vitro parasites.
The parasites in the body are: lung filariae, roundworms, whipworms, nephrodes, nodular nematodes, echinococcosis and so on.
Ectoparasites are: mites, mosquitoes, lice, flies, ticks and so on.
The most influential extratoparasite on pigs is mites (scabies mites), which is also one of the more common in vitro parasites in pigs. The harm of in vivo parasites to the pig body is relatively large, and in the later stage, it will compete with pigs for nutrients in the feed, and will also destroy the physiological functions and tissue structure of the pig's intestinal wall, liver and lungs, resulting in pigs "only eating for a long time", and immunity decreasing.
The author summarizes the main symptoms, treatment policies and prevention plans of the five parasites that have the most serious impact on the pig herd in the pig raising process.
<h1>The main symptoms of swine ascariasis and their prevention</h1>
Swine ascariasis is a common parasitic disease caused by swine roundworm parasitism in the small intestine of pigs. Pigs large and small can be infected, but piglets under 6 months of age have the most diseases, and are seriously affected, affecting growth and development, and often die due to complications or secondary to other diseases.
symptoms
About 1 week after the piglet eats a large number of invasive insect eggs, the larvae follow the blood through the neck to the lungs, which can cause ascaria pneumonia, showing lack of energy, loss of appetite, increased body temperature, cough, increased breathing, etc. Adults parasitize in the small intestine of pigs, take nutrients and secrete toxins, damage the intestinal mucosa, cause abdominal pain, mild diarrhea, wasting, anemia, growth and development and other phenomena. Occasionally, the worm body may obstruct the intestine, and in severe cases, it can cause intestinal rupture, or burrow into the bile ducts to cause obstructive jaundice and neurodegraded spasms.
prophylaxis
The disease should be mainly based on preventive deworming and fermentation of fecal mounds. Piglets should be dewormed 1 to 2 times during the 2 to 3 months of age after weaning, and sows should be dewormed once in the empty pregnancy period. At the same time, pens and utensils should be disinfected with 3% formalin or 2% sodium hydroxide solution every 10 days to kill invasive eggs. Pig manure should be treated with fertilizer outside the pen and accumulation fermentation.
treat
Castrocycles (piperazine compounds), 0.2 g per kilogram of body weight, mixed into the feed and fed, safe and effective.
Dichlorvos, 0.1 grams per kilogram of body weight, the total amount does not exceed 7 grams, combined with an aqueous solution once oral or mixed into the feed feeding, effective for adult insects.
Deworming net (tetrathiazole), 15 to 30 mg per kg of body weight, orally or mixed into feed to feed. Or at 10 mg per kilogram of body weight, mixed with 5% to 10% solution subcutaneous injection, the effect is higher.
Levimidazole, 7.5 mg to 8 mg per kg of body weight, is fed orally or mixed into the feed.
Mountain Road Year 0. 005 g/kg body weight, with calomel 0.003/kg body weight, once taken internally, 12 hours before taking the drug to 5 hours after taking the drug, do not feed.
<h1>The main symptoms and prevention of echinoccus pig disease</h1>
Echinoderosis is an internal parasitic disease called leech-shaped spinosa that parasitizes in the small intestine (mainly jejunum) of pigs. Humans and dogs can also be infected. The body is larger than that of pig roundworms, yellowish-white, slightly thicker at the front and smaller at the back.
When pigs are severely infected, they show digestive disorders, loss of appetite, abdominal pain and diarrhea, blood mixed in the feces, emaciation of sick pigs, intramuscular tremor, and abdominal muscle twitches.
Prevents pigs from swallowing intermediate host grubs (juveniles. worms, pupae, adults). Kill grubs and purify feces. Regular manure checks to find infected pigs should be kept in isolation or dewormed.
Combine the insect repellent and deworming net, 75 mg per head per kilogram of body weight, 15 mg net deworming, mixed orally once, once every other day, and used 3 times.
The combination of 10% nicotine sulfate (0.23 ml/kg body weight per time) and carbon tetrachloride (0.4 ml/kg body weight per time) has a certain effect.
<h1>The main symptoms and prevention of porcine lung filariasis</h1>
Pig lung filariasis is caused by the nematodes of the genus Posterior circle, so it is also called posterior roundworm disease, because the insect body is filamentous, and parasitizes in the bronchi and bronchi of the pig lung, so it is called swine lung filariasis. This disease is a common parasitic disease of piglets, which seriously endangers the growth and development of piglets, and even leads to death, so it is necessary to do a good job in prevention and control.
In pigs with mild infection, symptoms are often not obvious. Severe cases present with helminthic pneumonia and bronchitis. Sick pigs have paroxysmal cough, nasal mucus, shortness of breath, rales on auscultation of the lungs, coarse and dull hairs, slow growth, and emaciation and anemia.
prevention and cure
The pigsty should be built in a high and dry place, and the ground should be solid to avoid the presence of earthworms and the spread of pathogens. Enclosures can be disinfected with 1% sodium hydroxide solution or 30% ash water for grass and trees. The feces are stacked for fermentation. Pigs and pigs with insects should be repelled regularly.
Insect repellent method:
Net deworming is 20 to 25 mg/kg body weight per head orally and intramuscular 10 to 15 mg/kg body weight per head.
Levomidhi, dissolved in water orally or mixed in a small amount of feed, is fed at 8 to 10 mg/kg body weight per head.
0.1 g/kg body weight per head, formulated into a 30% solution, intramuscular or subcutaneous injection, once a day for 2 to 3 days.
<h1>The main symptoms and control of porcine cysts</h1>
Cysticercosis (cysticercosis) is a common parasitic disease in pigs. Porcine cysts are mainly parasitic in the muscles of pigs when people eat pork suffering from porcine cysticercosis can not only be infected with hook tapeworm disease, but also can also occur porcine cysticercosis. Therefore, it seriously endangers the health of people and pigs. Thanks to pork. The cysts in the shape of the rice grain embedded in the meat, so it is commonly known as: rice grits meat".
Prevention: To eliminate swine cysticercosis, it is necessary to carry out extensive publicity and take comprehensive measures such as "expulsion, inspection, reform, and reproduction".
Drive: If you want to completely expel the hook tapeworm in the human body, you must eliminate the source of infection of swine cysticercosis. Anthelmintic drugs are: chloronithiamine. Betel nut pumpkin seed blend and crane grass root.
Inspection: Strengthen the quarantine work of slaughterhouses, pig buying stations (points), and market trade sites. Detected cysticercosis pigs should be slaughtered separately, and cysticers pork factories should be conditionally processed, utilized or refined according to the degree of parasitism of the worms.
Change: Completely change the habit of building a thatched circle, that is, the toilet should not be connected to the pig pen, advocate raising pigs to go to the pen, and promote the accumulation method of high-temperature composting outside the circle to improve fertilizer efficiency and eliminate insect eggs and other pathogens.
Breeding: The implementation of "self-breeding and self-raising" is the way to develop the pig industry to prevent infection with swine cysticercosis.
<h1>The main symptoms and prevention of porcine scabies</h1>
Scabies is a common ectoparasitic disease caused by the parasitism of the scabies purpurea in pigs. The disease occurs severely in winter, and the infection is widespread by skin contact, if it is not treated in time, it will soon spread, and even the whole herd of pigs will be affected, causing serious losses.
Scabies likes to parasitize the head, neck, shoulders and other parts of pigs, and in severe cases, it can spread to the abdomen, limbs and even the whole body. At the beginning of the disease, the affected part is red, showing a sharp itch, and the sick pig is uneasy, often rubbing the itch on the wall, fence and other places. After a few days, the affected part appears small red dots, the hair falls off, the red dots gradually form blisters or pustules, after the rupture of the formation of rough scabs, the area gradually expands, the skin is thick or wrinkled, and in severe cases, the skin can be cracked, and then gradually emaciated, and even die
(1) The pig body and pen should be kept clean and dry frequently, the mat grass should be changed frequently, and the pig herd should have proper exercise and sunbathing to enhance the skin's disease resistance.
(2) Large and small pigs should be raised in pens, and the density of pigs should not be too high.
(3) When purchasing pigs, they should be carefully examined and fed separately for 1 to 2 weeks, and when there is no occurrence of this disease, they can be grouped together.
(4) If a sick pig is found, it should be treated in time; the same group of pigs can use 0.5% of the aqueous solution of the enemy worm, or 2% of the Lyso'er to spray the pig body. At the same time, pig houses, pens, pens and utensils should also be thoroughly disinfected, which can be disinfected with 10% to 20% lime milk; mat grass is burned or concentrated accumulation and fermentation, killing pathogens.
(1) Use 1% to 4% aqueous solution of dimethoate and directly rub or spray the pig body. It can be cured once every 5 to 7 days, usually 2 to 3 times.
(2) 1 part sulfur powder, 4 parts vegetable oil, fry, cool and rub. Or 1 part of kitchen tobacco leaves, add 20 parts of water, boil for l hours, take its water-soluble wave to wash the affected area.
When rubbing treatment with the above drugs, the whole body can be divided into four areas for generalized scabies and ringworm pigs, only one area is smeared a day, and after the whole body is rubbed again, every 2 to 3 days, and then apply it again, the medication should be selected when the weather is warm, first wash the skin of the affected part until it is congested and red; and then evenly apply the liquid, do not miss.
