It is no secret that worms in pigs can cause disruptions in the body. Animals become lethargic, sedentary, suffer from diarrhea. Infestation with parasites leads to a deterioration of appetite and slow muscle mass. This is directly reflected in the cost of pork and the profitability of the livestock farm. Failure to comply with sanitary and hygienic standards in the pigsty contributes to infection of pigs with various helminth infections.
Dangerous parasitic diseases of pigs
Infection of pigs with eggs, larvae, or adult forms of helminths is a serious problem faced by owners of small peasant farms and pig farms from time to time. The main reason for the spread of worms is the lack of hygiene standards in the care of animals, as well as the ingress of fecal masses into the feeders.
Worms in piglets reduce the rate of weight gain and significantly weaken their health. Young and immature individuals become susceptible to other infections, and their immunity weakens.
If you do not carry out timely treatment and treatment of the premises with antiseptics, then within a few weeks the entire population of your pigsty may be infected with dangerous worms. In addition to reducing the rate of increase in the average daily weight gain, certain types of worms can make the pork completely unsuitable for human consumption, and the livestock breeder will suffer very significant losses.
Signs and symptoms of helminth infections
The infection of pigs with worms may be indicated by a change in their behavior and other external signs that make it easy to distinguish a sick animal among healthy ones.
The main signs of worms in piglets are:
- loss of appetite and food left in the feeder;
- excessive appetite and eating feeds beyond measure;
- poor weight gain or loss;
- manifestations of nervousness and itching in the anus;
- increased body temperature;
- cough and hoarseness;
- vomiting or intestinal disorders;
- adult worms, their larvae or eggs are visible in the feces.
Often pigs infected with worms do not wish to communicate with other individuals of their herd and keep themselves isolated from them.
To determine the type of worms you need to show an infected pig to a veterinarian, as well as send a few grams of fecal matter to a laboratory test.
Affect meat quality and farm profitability
Helminths cause serious damage to pig farmers, because worms in pigs can cause several types of pathogenic effects on the body.
The larvae accumulate in the meat of pork and its implementation on the market becomes a huge problem. If you find worms in the intestines, lungs, or meat of a slaughtered pig, you must call a veterinarian who can determine the type of parasite and the suitability of pork for eating.
In most cases, the intestines of such pigs must be destroyed, for which it is best to burn it.
In no case should the worm of an infected pig worms be given to dogs and other domestic animals that themselves carry these parasites.
Novice breeders face a serious problem, not knowing whether it is possible to eat the meat of pigs with worms.
Now it remains to find out one of the main points: if pigs have worms, is it possible to eat meat after some kind of processing, for example, by boiling it.
Veterinarians give an unequivocal answer that infected meat cannot be eaten, because some types of helminths can be viable and develop in the human body itself.
In any case, before sending for slaughter, the pig must be thoroughly treated with antibiotics, and its slaughter can be carried out no earlier than 7-8 days after the completion of the medication. Read more in the article "About parasites in pork."
Types of worms in pigs
Worms affect not only adults, but also young animals, being transferred to piglets from sows. Depending on the methods of attachment, habitat, development cycle and the ability to move independently, the worms are divided into several large groups.
Nematodes can be localized in various organs and tissues of the pig. They have a different shape and reach a size from 1 mm to several meters, laying tens of thousands of eggs in the pig intestines.
Eggs go out into the environment along with feces, and infect the animal, into whose food they get.
The most common parasites of pigs are roundworm. These are worms that have an elongated body and reach a length of 35 cm. They are able to move independently and cause intestinal disorders in their host.
Cestodes have a ribbon-like body and are parasitic in the small intestine of a pig. They absorb the nutrients of the host, releasing into the external environment hundreds of thousands of eggs, coated with a protective sheath and long preserving their viability.
Trematodes or flukes can reach a length of 15 cm. They are localized in one of the host organs and feed on its blood.
Timely detection of pathogens
If you find signs of worms in pigs, then it will be very difficult to independently determine the parasites belonging to one of the species. The external manifestations of helminthiasis are very similar to each other, and only laboratory tests help to determine whether a parasite's eggs belong to a particular species.
The veterinarian will determine the symptoms and treatment of parasites for your pigs by prescribing medications that are required to be mixed into animal feed for several days.
One of the most dangerous diseases affecting the profitability of pig breeding is trichinosis of pigs. The causative agent of this helminthiasis is the nematode Trichinella spiralis, focal parasitizing in the small intestine of the host. A young pig or a pig that has become sick with trichinosis sharply loses interest in food, becomes inactive and lethargic.
Trichinosis and its danger
Females of the parasite are localized in the small intestine, damaging the mucous membrane with their hooks and suckers. A feature of the development of this parasite is that the adult female produces up to 2 thousand larvae, which are carried by the bloodstream to the body of a pig infected with trichinosis.
The larvae fall into all organs and tissues of the animal, but continue the developmental cycle only in the striated musculature, primarily in the muscles of the legs of the diaphragm, tongue, esophagus. In other tissues they die.
The symptoms of trichinosis are very similar to other infectious diseases. The main one is inflammation of the intestines, accompanied by diarrhea, toxicosis and vomiting. The piglet becomes sluggish and feels depressed. The disease may resemble pulmonary catarrh or pneumonia.
Effective treatment of trichinosis has not yet been developed, so when slaughtering sick pigs, a mandatory inspection of the carcasses by sanitary doctors is required, which decide on the use of pork for food or its utilization.
As a rule, the striated muscles of the pig infected with trichinosis are sent for destruction, and the rest of the pork is quite suitable for human consumption, although it requires careful heat treatment.
Another common helminthic disease is trichocephalosis of pigs, caused by the nematode Trichocephalus or pork whipworm. This parasite chooses a large intestine as a dwelling place, absorbing nutrients from the host.
An elongated worm body reaches a length of 3-5 cm. It does not have an intermediate stage of development. The eggs of the parasite come out with fecal matter.
In a warm and humid environment, they continue to develop, and are able to turn into an adult in 1-1.5 months. For this, it is necessary that a pig lovingly rummaging in fecal masses brought the pathogen eggs to its feeding trough or drinking bowl, and consumed them as food.
Most often trichuriasis sick piglets that become infected at the age of 2-8 months. They have an inflammatory process in the rectum, manifested in constipation. Animals suffer from exhaustion, and the most weakened of them may even die.
Since the pork whipworm is not localized in the muscle fibers, the consumption of the meat of a sick animal is allowed.
Other parasitic diseases
Macracantorina pigs are called Macracanthorhynchus hirudinaceus, the female can reach a length of 68-70 cm. Pigs become infected by eating intermediate hosts - insects, be it rhinoceros beetles, cockchafer, bronze or dung beetles.
The worm can be in the body of a pig for up to two years, and its eggs retain their vitality for 2.5 years. He lives in the small intestine, causing diarrhea, bleeding and peritonitis, which can lead to the death of the animal.
Scraper carriers are immediately sent for slaughter, as further feeding of the pig is not cost-effective.
Echinococcosis of pigs is caused by the larval form of tapeworm Echinococcus granulosus, the main carrier of which are dogs. They themselves become infected by the larvae, eating the meat and guts of the pigs. An adult parasite that grows in their intestines produces eggs that are distributed along with feces.
The larvae are localized in the internal organs of the pig, most often in the liver, causing its atrophy. With localization in the lungs cough appears. When the affected organs of echinococcus are sacrificed, they must be sterilized and disposed of.
No treatment can not do
Extremely dangerous helminthiases are fasciolopsis, echinosaciasis, cysticercosis, ascariasis, trichurosis, esophagostomosis, olllulanoz, each of which has its causative agents.
For helminth infections that are not subject to treatment include macracanthorhinhoz, echinococcosis, sparganosis, which are carried by small rodents. It is best to isolate the pig infected with such helminthiasis immediately from the rest of the herd and send for slaughter.
Remember that the sale on the market of worms infected with pork and beef is unacceptable, and such meat must be destroyed.
Therefore, the animal must first be treated. The veterinarian will advise how to remove the worms from the pig, using the methods of traditional and traditional medicine. Today there are a large number of drugs that can paralyze an adult parasite or kill its larvae without causing health problems in the animal itself.
Starting from the age of two months, the piglets from worms can add sodium fluorosilicate powder and Gigrovetin to the feed, and suckers are given a subcutaneous injection of the Nilverm preparation.
Adult pigs can be treated by folk remedies, as well as by means such as Albendazole, Baymek, Fenbendazol, Levamisole or Dektomax, each of which has a specific effect.
