If you want sheep to be healthier, deworming is very important. What are the medicines to deworming sheep?

The problem of disease and pest control in sheep is a major problem in sheep production. Parasitic diseases, infectious diseases and common diseases of sheep constitute the three major diseases of sheep. Among them, although sheep parasitic diseases are less harmful than sheep infectious diseases and common diseases, sheep parasitic diseases can affect every sheep. This is also an unavoidable disease for every sheep, so sheep farmers should pay great attention to it.

Spring is warm, flowers bloom and everything comes back to life. This is a good time for sheep to gain weight and rejuvenate. Parasites must not affect the normal growth of sheep. In late February or early March, ivermectin can be administered orally by subcutaneous levamisole to co-deworm.

This is effective in repelling most internal and external parasites. If sheep farmers do not have the trouble of subcutaneous ivermectin, they may also choose to administer ivermectin-albendazole powder mixes or tablet anthelmintics orally to the sheep, but ivermectin is not as stable in absorption as subcutaneous injection.

After deworming, be sure to remember to clean the sheep house, strictly disinfect the sheep house, trough, etc., to prevent the parasites in the environment from re-infecting the sheep. To enhance the deworming effect, you can reapply drug deworming about 10 days after your first deworming so that you can remove lost parasites.

The sheep should be sheared after summer. After shearing, sheep can be sprayed with trichlorfon or amitraz solution at a concentration of 0.1% or treated with a medicinal bath. In general, spraying is sufficient when sheep show no obvious symptoms of ectoparasites. When there are obvious ectoparasite symptoms, such as hair removal or more parasites can be seen, in which case insecticide baths work better.

In addition, lambs are more prone to coccidiosis in the summer, mainly in the case of continuous rain and wet mud, coccidids in the environment can infect the lamb through the digestive tract, so the lamb should also be fed some coccidid-preventing drugs such as descraculi. Of course, when the barn is in good health, lambs have fewer coccidia, so there is no need to use drugs to prevent coccidia.

Fall and winter deworming can be done from September to October. After deworming, sheep can quickly gain weight and overwinter. Sheep can overwinter normally only if they keep good fat. At this point, ivermectin can be injected subcutaneously and albendazole can be taken orally for combined deworming. Similarly, ivermectin-albendazole powder or tablet repellent can be used orally in sheep.

This is why levamisole is replaced by albendazole in the fall and winter. Levamisole is more specific for nematodes and hookworms, but has almost no effect on Fasciola hepatica, while albendazole has a wider repellent range and has some effect on Fasciola hepatica.

In general, deworming is not done in winter, but in autumn, when deworming is incomplete and the sheep have obvious symptoms of parasites, it must be intensified so that the parasites do not affect the normal overwintering of the sheep.

The incidence of parasitic diseases in sheep is high and sometimes causes serious economic losses. Therefore, there is an urgent need to rid sheep of parasites. In general, sheep farms should be regularly dewormed 2-3 times a year, about once from March to April, and once from December to January of the following year. There are many commonly used drugs to expel internal parasites, such as levamisole and trichlorfon to expel nematodes; Praziquantel and albendazole are used to repel tapeworms and flukes; Ivermectin and avermectin, which expel internal nematodes and external parasites.

Precautions: Pregnant ewes should not be treated with insect repellent, which can cause miscarriage; Many parasites can be infected together, so use a combination of two or more repellents; Dewormed sheep manure should be collected and transported to a low-lying area below the sheep farm or nearby fields for accumulation and fermentation, which can be used as fertilizer after 1 month.

Choose a clear, windless day to bathe the sheep. The medicine bath is generally performed within a week after shearing, and adequate water should be added before the medicine bath. There are two kinds of medicine bath: fixed medicine bath and mobile medicine bath. The mobile medicine bath can be used in agricultural areas with few sheep, while the stationary medicine bath is used in large sheep farms. Sheep are usually bathed with a medicated solution containing 0.5% trichlorfon. The specific preparation method is: add 2 jin of trichlorfon drug into 400 jin of warm water, after stirring fully, it can be used for 40 sheep medicine bath.

Note: Sheep with external wounds can not take medicine bath; Pregnant ewes had better not be medicated bath; When taking a medicine bath, wash the healthy sheep first and then the sick sheep; Some sheep that are not suitable for medicated baths can be showered for deworming
