China's rapid economic development, animal husbandry industry breeding technology is also constantly improving, however, due to the poor breeding conditions of cattle and sheep farmers in China, the epidemic prevention and disinfection is not perfect, coupled with the awareness of the prevention and control of cattle and sheep parasitic diseases is not strong, so that the infection rate of cattle and sheep parasitic diseases is high and the cure rate is low, causing harm to the yield and quality of cattle and sheep products, causing harm to the quality of cattle and sheep products, causing cattle and sheep product quality to be substandard, causing cattle and sheep to die, and even causing common diseases between humans and livestock, which in turn affects human health. Therefore, we must pay attention to and strengthen the prevention and control of common parasitic diseases in cattle and sheep. It's autumn again, it's the season of cattle and sheep deworming, and veterinarian Lao Wang tells you how to deworm well.
There are more than 30 kinds of common parasites in cattle and sheep, and the common in vivo and foreign parasites of cattle and sheep mainly include intestinal tapeworm, liver chip flukeworm, twisting stomach worm, intestinal tubercles, hookworm, whipworm, lung filaria, scabies, sheep nose fly, sheep lice, ticks and brain hydatids and schistosomiasis, etc., and even a variety of parasites often cause mixed infections, some parasitic diseases and even zoonotic parasitic diseases, such as liver slice trematodiasis. After the emergence of parasitic diseases in cattle and sheep, there is generally emaciation, jaundice, malnutrition and other conditions.
First, cattle and sheep common parasitic diseases
1) Tapeworm disease
The most common is Moniz tapeworm. The body of the insect is 1-5 meters long, white, slender. It mainly parasitizes in the small intestine, and in severe cases, the worm body blocks the intestinal tube. Goats infected with tapeworm disease are quickly emaciated, their fur is coarse and dull, their appetite is reduced and their appetite increases, and they develop diarrhea, anemia and edema, and, in a few cases, neurological symptoms.

2) Liver fluke disease
Also known as liver leeches, the insect body is flat, much like a leaf, slightly larger than pumpkin seeds, parasitizing the liver and bile ducts of sheep, with an infection rate of 20%-30%. Goats with liver fluke disease are emaciated, anemic, submandibular edema, and later diarrhea occurs, and finally leads to liver poisoning and exhaustion and death.

3) Gastrointestinal nematode disease
Common are twisted stomach worms, intestinal tubercle worms, hookworms, whipworms, etc., and the infection rate can reach 100%. Symptoms are: body emaciation, decreased appetite, blood poverty, sometimes diarrhea, more often in the spring, summer, autumn three seasons.
Twister stomach worms mainly parasitize in the true stomach. The insect body is 10-30 cm long, mainly to harm the true gastric mucosa and glands and secrete toxins. Sick sheep are mentally weak, emaciated and anemia, growth and development stop, diarrhea, often and anterior stomach diseases coexist with death.
Intestinal tubercoles predominate in the large intestine. The insect body is 10-20 cm long and forms countless nodules on the intestinal wall ranging in size from rice grains to broad bean grains. After a large number of nodules proliferate, the intestinal peristalsis, digestion and absorption function are seriously impaired, and the obvious symptoms of sick sheep are malnutrition, weight loss, blood in feces when diarrhea, and paralyzed hind limbs when severe.
Hookworms mainly parasitize in the small intestine, feeding on sheep's blood, causing ulcers of the intestinal mucosa. Extreme anemia, emaciation, submandibular edema, and long-term diarrhea in the affected sheep can cause a large number of deaths in sheep.
Whipworms are mainly parasitic in the large intestine and cecum. The body of the insect is 35-70 mm long, and after the infection of the sheep body, the general symptoms are not obvious, and when it is severe, it causes diarrhea, and causes anemia and decreased appetite due to the absorption of toxins

4) Pulmonary filariasis
Also known as reticulode nematode disease, it is a disease caused by reticulo nematode parasitizing the bronchi of the lungs. Main symptoms: continuous coughing, emaciation and weakness, runny nose, sneezing, dyspnea, often suffocated due to obstruction of the airways by insect blocks.

5. Scabies
Also known as "mite disease", to hair removal, itching as the main features, mostly in winter, spring, especially in winter spread the fastest. The disease is extremely itchy, manifested as rubbing everywhere and biting with the mouth, causing the skin to become inflamed and abscessed, the skin thickens and is covered with a large number of scabs, and the wool falls off in large pieces, especially the head. Sick sheep often die of chronic restlessness, anemia and wasting.

6) Rhinophila maggot disease
Sick sheep present with inflammation of the upper respiratory tract, large amounts of nasal discharge, pus, sneezing, coughing, and wasting. People who invade the trachea and lungs have difficulty breathing, and those who invade the sinuses and affect the meninges can cause neurological symptoms. The disease can recur periodically until death.

7) Echinococcosis
Also known as "crazy sheep" and "circle disease", the brain nerve symptoms based on circles are obvious and easier to diagnose.
Hydatid cerebropods
8) Schistosomiasis
Sick sheep have diarrhea, mucus and blood in the feces, increased body temperature, pale mucous membranes, increasing emaciation, and stunted growth and development, which can lead to infertility or miscarriage. It is mainly manifested as submandibular and sub-abdominal edema, anemia, jaundice, wasting, developmental disorders and affecting the fetus, miscarriage, etc., such as poor feeding management, which can eventually lead to death.
schistosome
At present, parasitic diseases in cattle and sheep show a trend of increasing infection rate, increasing infection intensity, susceptibility of different ages and sexes, and increasing mortality rates year by year. The shortcomings of traditional insect repellent methods are obvious: poor effect, easy to produce drug resistance, multiple toxic side reactions, and large amount of deworming workload.
In order to optimize the deworming mode and reduce the losses caused by parasitic diseases to the cattle and sheep breeding industry, after long-term market research, veterinarian Lao Wang visited a large number of cattle and sheep farmers, and after a long period of deworming tests, launched the joint drug deworming "2+1" deworming model:
1 The composition of the drug of this model
Albendazole suspension + ivermectin solution
Endosome net - iodosesalamide suspension
2. Advantages of the mode
(1) Strong combination, wide deworming spectrum: simultaneously kill gastrointestinal nematodes, trematodes and parasites in vitro.
Albendazole suspension + ivermectin solution has a special effect on all nematodes, tapeworms and trematodes, mites and parasitic insects, and the endosome net- iodother salixamide suspension has a special effect on liver flukes and large trematodes.
(2) Liquid dosage form, accurate dosage: avoid the problem of inaccurate dosage of filling tablets and uneven intake of mixing materials and drinking water.
(3) Completely kill and eliminate drug resistance: directly kill the insect body, avoid the resurrection of the insect body, and produce drug resistance.
(4) Drinking water can be mixed, the workload is small, the small scale of the field can be filled, easy to apply.
3. Recommended Dosage:
Ivermectin solution is applied once per 30 kg of body weight cattle and sheep with 2 ml.
After 7 days, the albendazole suspension is applied once per 30 kg of body weight of cattle and sheep with 4 ml kg.
After each week, the endosome net-iodother salion suspension should be applied once with 15 ml of cattle and sheep at a time according to the situation.
4, specific applications
(1) Newborn lamb calves:
35 days old first drive, apply once according to this program
60-day-old two-wheel drive, applied once according to this program;
(2) New cattle and sheep:
(1) Apply once according to this program to kill adult insects.
(2) After 7 days, apply once according to this procedure to kill the insect eggs.
