Breeding cattle inevitably accompanied by the fight against parasites, among them - the worms in cows. The world of worms is large and diverse, their infection manifests itself in different ways. It happens that the disease has no pronounced signs. At the same time, the productivity of animals decreases, they slowly gain weight, there are problems with reproduction. We have to increase feed consumption. In advanced cases, worm diseases can disrupt vital processes so that they lead to the death of animals, especially for young cattle.
What is dangerous helminthiasis
Parasites exist at the expense of their host: use the cells of its tissues, take away nutrients, vitamins and minerals. Their metabolic products are generally toxic. Settling in any organ, they are able to block the ducts and cause inflammation. Parasites disrupt the natural circulation of substances in the body, lead to structural damage, causing chronic diseases.
In severe cases, for example, when infected with tapeworms, in the intestines of the cow there is inversion of the intestines, and even strong drugs are powerless here. If the liver is damaged by flatworms (fascioli), a high concentration of worms in a cow can lead to fatal peritonitis. High invasion by dikrocelii disrupts the digestion process, as a result of which the cow receives cirrhosis.
How does the infection occur?
The biological food chain contributes to the spread of helminths: parasite eggs, along with the faeces of infected animals, infect pastures and livestock housing. When grazing together, worm infestation along with grass is passed from one group of animals to another. So, for example, tapeworms, which usually settle in sheep, also infect cattle.
On wet soils, snails or ants feeding on contaminated manure can become carriers of the worms larvae. Moving through the pasture, they, along with the grass, themselves become food for cattle, while infecting cows, for example, with fascioli or wild broods.
Eggs and larvae of worms enter the body of livestock in other ways: along with contaminated water or insect bites.
Features of helminthiasis in young
The body of the calf is more susceptible to helminth infection and more often experiences serious complications. Calves are infected not only by cow parasites, but also by worms from lambs. For young cows, high invasion can be fatal. For example, with dictyocaules, helminth larvae settle in the walls of the intestine, from where they penetrate into the pulmonary capillaries. The structure of the vessels is broken, respiratory functions are almost lost. Blocking the respiratory system can result in the death of an infected calf.
Often it is the worms in calves that lead to digestive disorders, decreased appetite and severe pneumonia, taking away energy and strength for growth. Without timely treatment, some types of helminthiasis in young cattle end in death.
How to reduce the chance of infection
Cattle are in constant contact with possible sources of infection by parasites. Eliminating helminthiasis is almost completely impossible, but you should try to reduce the likelihood of infection. To do this, follow these rules:
- monitor the quality of water in drinking bowls, prevent water from stagnant water;
- control the quality of feed, prevent the use of hay lying underfoot;
- maintain cleanliness and dryness in cattle rooms;
- twice a year to carry out general disinfection in stalls and in common courtyards;
- young animals are separated from the adult herd;
- observe pasture change;
- carry out systematic deworming of livestock.
A single farm animal can excrete several million worms eggs per day with faeces into the environment. Therefore, regular cleaning and reliable disinfection of manure in premises for cattle can reduce the spread of helminths.
What drugs will help get rid of invasions
For the destruction of worms in cows, there is a wide range of drugs that neutralize parasites by various methods. These include:
- alvet and flubendazole, which affect the worms nutrition system;
- Albendazole (Alben), which suppresses the metabolism of parasites;
- tetramisole, causing paralysis of the worm;
- febtal, violating the carbohydrate metabolism of worms and the ability to reproduce.
Veterinarians most often prescribed broad-acting drugs. For example, Alben is a complex anthelmintic agent of the new generation, acting at all stages of the development of parasites. Active against cestodes, nematodes, and trematodes. Alben is available in tablets, administered once, low toxicity if the instructions are followed, it can be used for removing worms in calves and milk cows.
It has long been practiced removal of worms with the help of folk recipes. However, this process is long, often with individual intolerance causes undesirable reactions in the animal. The most benign and effective of them is recognized as castor oil.
Fighting worms with folk remedies can be dangerous for the animal and requires veterinary control.
What you need to remember in the anthelmintic treatment
If a parasitic disease is found in individual animals in the herd, then all cows and calves should be treated. Properly selected modern drugs can rid the body of the animal from worms.
Medicines are taken orally, according to the instructions. The dose of the drug should be strictly controlled in accordance with the weight of the animal. For example, for cattle, Alben is given at the rate of one tablet per 50 kg of animal weight. In some types of invasions, it is possible to increase the dose to 35 kg per tablet. Before treatment, it is best to consult a veterinarian. Virtually all anthelmintic drugs have side effects. Overdose can be dangerous for the animal.
Experienced owners advise to perform the procedure together: it is necessary for the partner to hold the animal's head in the correct position. After the procedure, the time and name of the drug should be recorded. All used instruments need to be disinfected.
The dangers of cow helminthiasis for humans
As a rule, worms parasitize on certain types of living organisms. Many cow helminths are not dangerous for sheep or goats, and vice versa. However, some species of worms in cows are dangerous to humans.
Care should be taken when handling infected animals. Milk from infected cows should not be eaten, as well as given to other pets. After treatment with anthelmintic drugs for some time neither milk nor meat is suitable for humans. For example, taking Alben implies restrictions on meat products for at least three weeks and milk for a week. It should be remembered that the drugs themselves to combat worms are to a certain extent toxic. During the medical procedures can not drink, eat, smoke.
Launched helminthiasis leads to various complications and is more difficult to cure. Given that infection can be difficult to recognize, it is recommended that anthelminthic prophylaxis be used regularly — twice a year, in the fall and spring.
Having an idea about the symptoms and treatment of helminthiasis in cows, the owners can notice the infection of their pets with parasites on time. Timely consultation with a veterinarian and the use of appropriate drugs will help maintain livestock productivity, and competent prevention will reduce the likelihood of helminth infection.
