Is there a worm in the stomach and intestines if the cow s hair is not smooth?

1. How does bovine lung nematode disease occur?

The disease is caused by several nematodes parasitic in the bronchi and trachea of cattle. The pathogens are mainly filamentous reticulotail nematodes and viviparous reticulotail nematodes. Female worms ovulate, reach the pharynx or oral cavity with bronchial and tracheal secretions, enter the gastrointestinal tract through swallowing, and are excreted with feces.

Under suitable external conditions, it can develop into an infectious larvae. In a humid environment, such as in the early morning when there is dew, this larvae like to crawl on the grass, when the cattle eat the infectious larvae, the larvae invade the blood vessels and lymphatic vessels of the intestinal wall while developing, and with the blood circulation to the lungs, from the blood vessels into the alveoli, from the alveoli gradually swim to the bronchi, trachea, where they mature and lay eggs. The conditions for the development of eggs in the outside world are warm and humid, so spring and summer are the main infection seasons for the disease.

2. What are the key points in the diagnosis of bovine lung nematode disease?

The key points of diagnosis are as follows: 1. During the epidemic season in endemic areas, pay attention to the clinical symptoms of the disease. It is mainly a cough, but the body temperature is generally not high, and the coughing of the cattle can be heard during the night rest or early in the morning, as well as the sound of breathing like a wind box, and the cough is worse when driving the cattle.

Sick cattle often have sticky nasal discharge from their nostrils and often sneeze and squirt. Coarse coat, gradual emaciation, anemia, edema of the head, chest, and limbs, rapid breathing, and difficulty breathing. Calves have severe symptoms and can cause mass deaths during the harsh winter months.

If the infection of adult cattle is mild, the symptoms are not obvious, and the process is chronic. 2. Eggs are examined with feces or nasal fluid, and if eggs or larvae are found, the diagnosis can be confirmed. When necropsy of sick and dead cattle, if the mucosa of the bronchi and trachea is swollen and congested, and there are small bleeding spots, there is more mucus in it, mixed with blood streaks, and there are more worms, eggs or larvae in the mucus mass, it can also be diagnosed.

3. How to prevent and control bovine lung nematode disease?

To prevent, the first is to graze in dry and clean pastures, and pay attention to the hygiene of drinking water for cattle. The second is to clean the cowshed frequently, ferment the manure and urine to kill the eggs. Third, it is necessary to concentrate on deworming in spring and autumn every year, or when cattle are converted from grazing to house feeding.

However, the feces after deworming should be strictly managed, and the eggs must be fermented to kill the eggs.

**, propyl dibenzole should be used, 5-10 mg per kilogram of body weight, prepared into a suspension, and administered once. Tetraimidazole, which can be administered by aerosol, is carried out in a closed barn, and the cattle should be allowed to stay in the barn for 20 minutes after spraying. 1% ivermectin injection, one subcutaneous injection per milliliter per kilogram of body weight.

Cyanoacetyl hydrazide, milligrams per kilogram of body weight, orally, the total amount should not exceed 5 grams. Only one dose is required at the beginning of the disease, and 2-3 consecutive doses can be given in severe cases.

Possibly, you can get a veterinarian to check it out, or pioneer deworming a try. If the cattle have been straining, the cow will also have bad hair, because the livestock grow well and generally have shiny fur.

Most of this disease is caused by fascioliasis hepatica, and the control method is oral nitrochlorophene, taking 3-4 ml per kilogram of body weight. Pentium Animal Husbandry Beef Cattle Breeding Farm provides improved breeds and exchanges technology.

There are five main types of nematodes that cause bovine gastrointestinal nematode disease. Its various life characteristics are:

1) Twist the stomach worm. It is parasitic on the true stomach of cattle, occasionally seen in the small intestine, and the body of the fresh worm is pale red, 15-20 mm long, hairy. Adults lay eggs in the true stomach and are discharged to the outside world, and develop into larvae in about 7 days, and cattle swallow larvae for 20 to 30 days to develop into adults.

2) Hookworms. Parasitic in the small intestine, the worm body is 10-30 mm long, grayish-brown, and the head is curved to the back in a hook-like shape. Adult worms lay eggs in the small intestine, develop into larvae in the outside world for 8 days, and develop into adult worms through oral or ** infected cattle.

3) Nodules. Parasitic in the large intestine, the larvae form nodules in the intestinal mucosa, the adult worms are milky white, 10 20 mm long, the adult ovulates and hatches as infected larvae in the outside world, enters the digestive tract through the mouth, and burrows into the mucosa of the large intestine to form nodules.

4) Broad-mouthed round worm. Parasitic on the colon and cecum. 15-30 mm long, pale yellow in color, the female lodges in the intestine to lay eggs, developing into infectious larvae in the outside. Cattle are infected by ingesting the larvae, which develops into adult worms in the intestine after 50 days.

5) Whipworms. Parasitic in the cecum, 35 80 mm long, the head is as thin as hair, the tail end is thick, resembling a whip, the eggs are excreted with the feces for about 2 weeks to develop into infected young eggs, through the digestive tract of cattle infection.

Bugs in the belly of cattle are generally parasites.

A parasite is an organism that spwells most of its life on another animal, called a host or host, and at the same time, causes damage to the parasitic animal. That is, all organisms that are in or attached to the host or host to obtain the nutrients or shelter necessary for their survival, development or reproduction. Many small animals survive in a parasitic manner, attaching themselves to animals larger than them.

Broadly speaking, bacteria and viruses are also parasites.

Parasitic infection] Cattle can be infected with parasites by the following methods:

1. Drinking water containing parasite eggs;

2. Eating food containing parasite eggs, including plants and breast milk;

3. Infection of other small animals (cats, dogs, etc.);

4. Infection with parasites due to trauma;

5. The bite of insects with parasite eggs;

6. Feces contaminate food, water sources, etc.

Prevention and control methods] 1. Pay attention to the hygienic conditions of cattle raising, especially water sources and food;

2. Reduce the feeding of small animals near the cattle farm, and pay attention to rodents, mosquitoes and flies;

3. If parasites are found, they will be eliminated and eliminated immediately according to their species.

The cow's is a cow tapeworm, no great harm to the human body, the picture is not clear, if it is a section of a very long section, it can be eaten if it is cooked, if you are not at ease, the pressure cooker cooks it.

I'll you. Throw it away, you can't eat it.

1 Common parasitic diseases in cattle and sheep.

Pyrosomiasis is an insect-borne disease transmitted by ticks. Pyrozoa parasitizes red blood cells, and the main clinical symptoms are high fever, anemia or jaundice, cessation of rumination, cessation of lactation, loss of appetite, and death in severe cases of weight loss. The disease is caused by the breeding of char worms in the body of ticks and the bite of ticks when cattle and sheep are grazing.

It is mainly sporadic and endemic epidemic, mostly occurring in summer and autumn, and the peak incidence is in July and September.

HelminthiasisHelminthiasis is the most common parasitic disease of cattle and sheep, and it is the most harmful parasitic disease. These include tapeworms, flukes, and nematode diseases. It is widely distributed in different parts of our country.

Some worms that live in various organs of cattle and sheep can cause serious pathological changes and are often irreversible. For example, when dairy cows suffer from flukeiasis, milk production decreases by 10 15; When sheep suffer from flukeiasis, the amount of shearing decreases7 12. In addition, if the disease passes in a hurry, it often causes the death of cattle and sheep, especially sheep.

If cattle and sheep are exposed to a high-intensity attack of Monitz extensions, it can cause mass mortality of young animals. Cattle and sheep infected with double-lumen flukes can have a huge impact on their performance. Often, fasciola hepatica and flukes parasitic in the liver of cattle and sheep at the same time, and their pathogenic effect is enhanced.

Tick-borne diseases.

It is mainly that ticks parasitize on the body surface of cattle and sheep, and invade them by sucking the blood of cattle and sheep, and at the same time, ticks are the most critical spreaders of pyroworm and rickettsial disease, and their destructive effect is very large.

Bovine and sheep nose fly disease.

Nosefly disease in cattle and sheep is mainly caused by nasal flies parasitic in the nasal cavity of cattle and sheep, which leads to sneezing and runny nose in cattle and sheep, and even purulent nasal discharge or severe pneumonia in severe cases.

Answer dear, hello, I will help you answer this question, I am answering it for you, please wait a while, don't be too anxious, I hope my answer can help you, solve your troubles, I wish you a happy life and good health.

Hello, there are worms in the belly of the cow, and the cow may have these reactions. Cattle lose their appetite and become thin and thin, their coat is backwards and dull, and their hair falls off to form scabies, which is a sign that cattle have parasites. Different parasites will have other different manifestations, such as edema in the head, abdomen and other parts of the cow may have Fasciola hepatica, cattle frequent cough, dyspnea but no fever and other respiratory tract infection symptoms may have lung filaria, cattle body temperature rises to 40 42, loss of appetite, blood in the stool, blood becomes thin may have Taylorella bovis.
