Common parasitic diseases in cattle and prevention and control measures

author:Swine Disease Classroom

As a hermit animal, the parasite is attached to the host body, and in the process of growth, development and reproduction, it will have a huge impact on the host, destroy the immune function of the cow, absorb the nutrients of the cow itself, multiply, cause physical damage to the cow, and may even produce zoonotic diseases, endangering the breeder and other healthy cattle. There are many types of bovine parasitic diseases and their distribution is relatively wide; cattle are very susceptible to factors such as environment, season, feeding and management methods in the feeding process, resulting in the occurrence of parasitic diseases; this paper briefly analyzes the identification and treatment of bovine parasitic diseases.

Common parasitic diseases in cattle and prevention and control measures

Common parasitic disease symptoms and differentiation in cattle:

1. Bovine coccidiosis

The source of bovine coccidiosis is parasitism parasitizing the bovine intestine and causing clinical hemorrhagic enteritis, there is an incubation time of about 2 to 3 weeks before the onset of the disease, the entire pathogenesis process is about 10 to 15 days, due to the destruction of the intestinal mucosa by parasites, and after the bacterial infection, the clinical manifestations are bloody stool and abdominal pain; at the beginning of the disease, the sick cow is depressed, loose with hair, and the body temperature is slightly elevated or normal. The stool is thin and slightly bloody. After about 1 week, the symptoms worsened, the sick cow was deprived of appetite, emaciated, mentally weak, and liked to lie down. Body temperature rises to 40 ° C to 41 ° C, rumen peristalsis and rumination stop, intestinal peristalsis increases. Discharge of thin feces with blood, mixed with a fibrous pseudo-membrane, foul odor. At the end of the disease, the stool is black, almost all blood, the body temperature drops, and it dies in a cachexia state. During the wet and rainy seasons of summer and autumn, it is endemic; the disease is often found in calves.

Prevention and control measures for bovine coccidiosis: For cattle infected with bovine coccidiosis, the drug dinofloxamycete can be selected, and then the dosage is selected according to the age of the onset of cattle, the specific incidence of the disease and the degree of the disease. If 3 consecutive injections are ineffective, vitamin injections are given to prevent rebleeding in the intestine.

Formula 1: Tampere, according to 20-50 mg/kg body weight, take once internally for 5-6 days.

Formula 2: Sodium sulfamethazine injection, 100 mg/kg body weight, once intramuscularly once daily for 5 days. After 2 days of continuous use, it was converted to internal medication.

2. Bovine mite disease

Bovine mite disease has a strong contagiousness, it is mainly divided into two categories, scabies mites and itch mites, the symptoms after infection are: causing local hair removal, dermatitis that damages the skin, etc., after infection with this disease, a mixed infection will occur, resulting in itching of the skin around the cattle body

, causing the cow to rub the affected area for a long time, causing the skin to thicken until the lesion spreads throughout the body. This leads to a decline in the appetite of cattle, and the increasing wasting affects the health, which leads to stagnation of its growth rate.

Prevention and control of bovine mite disease

First of all, managers and breeders should regularly clean the barn, improve ventilation in the barn, regularly disinfect the barn with 1% of the solution of the enemy worm, and pay attention to the living environment of the cattle.

Western medicine treatment: The affected area of the cattle is treated locally, and the affected area of the cattle is sprayed with 0.5% of the insects, once a week. The drug ivermectin 0.2 mg/kg·bw was also used for subcutaneous injection.

Traditional Chinese medicine treatment: Fang Yi Sulfur 30 g, Peppercorn 30 g, Wood Turtle in 30 g, Maple in 30 g, Mercury 6 g, Cnidium monnieri 60 g, Salt 15 g, Walnut Kernel 120 g. Study the fine powder together, mix with cotton oil and apply it evenly to the affected area.

Fang 2 500 grams of vicious poison, 150 grams of torch sulfur, 45 grams of fried white pepper. A total of fine powder, take 30 grams of medicine, add 750 ml of boiling vegetable oil and stir well, after cooling, apply the affected area with a brush with a handle.

3. Liver tablets fluke disease

Liver flukes are a major parasitic disease in cattle. The pathogens of liver fluke trematodiasis are liver flakes and large trematodes. The insect parasitizes in the bile ducts of cattle and can cause cholangitis, hepatitis, and liver hardening. The nutritional decline of sick cattle, the reduction of milk production in dairy cows, and sometimes even death, are more harmful to cattle.

symptoms:

The severity of symptoms is related to the number of insects and the age and constitution of the cattle. Clinical symptoms are generally absent and can cause onset in severe infection. Acute cases present with sluggishness, diarrhea, tenderness of the liver, and sometimes sudden death. In chronic cases, cattle suffer from depression, coarse hair, loss of appetite, slow walking, pale membranes, followed by periodic rumen distension or anterior gastric relaxation, diarrhea, and increasing emaciation. In the later stages, edema appears under the jaw and under the chest, there is a feeling of fluctuation or dough-like sensation on palpation, severe anemia, decreased fertility of bulls, infertility or miscarriage of cows, and often death due to extreme exhaustion.

treat:

1, nitrochlorophenol is an ideal drug for expelling bovine and sheep liver tablets, this drug has three types of powder, tablets, injections, the first two types can be filled, can also be mixed in the feed, the amount of irrigation according to fattening cattle per dry gram hugh weight administration 3-4 mg injection dosage of 0.5-1 mg per dry gram hugh weight, injection of insect repellent convenient, high accuracy. When poisoning occurs. Inject glucose solution* or lead the cow to a cool place and spray with cool water.

2. Thiobisdichlorophenol, taken internally, 40~60mg per kilogram of body weight.

4. Psoriasis

Psoriasis is a very common parasitic disease in breeding, which will cause a significant decline in cow milk production, and will cause calves to be unable to grow and develop normally, at the same time, once infected with cow skin maggot disease, the cortex of cattle will have a stepwise decline, which is very unfavorable to cattle breeding, and will also lead to a decline in the economic income of farmers. Psoriasis usually occurs in the summer, when the temperature is relatively high, mosquitoes and flies multiply in large quantities, which in turn leads to the occurrence of psoriasis, and when the larvae burrow into the skin of cattle, they cause itching, restlessness and local pain. The larvae migrate in the body for a long time, causing tissue damage, causing pharyngitis and inflammation of the esophageal wall when the pharynx and esophagus are migrated. The impact on the normal rest and feeding of cattle will also cause the problem of abortion of cows, so it is imperative to effectively prevent and control maggot disease in cow skin.

Western medicine treatment

The extermination of migrating larvae can be injected intramuscularly into the buttocks in 10% to 15% refined aqueous solution of 0.1 to 0.2 ml/kg body weight, respectively, in mid-October and late January of the following year. Or in 11 to 12 months with hypothion, 7 mg / kg body weight, intramuscular injection. To destroy the larvae that have not yet reached the subcutaneous skin of the back of the cattle, 10% or 15% of the dimethodium solution can be used, and at the end of the mosquito activity season every year, with ivermectin or epimycin, 0.2 mg / kg body weight, a subcutaneous injection can effectively prevent psoriasis.

Fang 2 kg of angelica, soaked in 4 liters of vinegar for 48 hours, in mid-September, early October, to the back of the cow on each side of the dip once, the big cattle with each dip of 150 ml, the calf with 80 ml, to soak the coat and skin as a degree.

Fang 2 Pulu tea (gourd tea) loo grams, Chen lime 25 grams, mashed compresses the affected area.
