Deworming methods of pregnant ewes

Raising sheep is now a very important breeding project in many parts of our country. When raising sheep, we should do a good job in management to ensure the healthy growth of the sheep. Therefore, we should strictly follow the process to carry out deworming and epidemic prevention. Avoid producing parasites and various diseases that affect the growth of ewes. But if it is a pregnant ewe, can it be dewormed? How do you get rid of worms? The following editor will introduce it for you, let's have a look!

1. Drug selection

When deworming pregnant ewes, we must first choose appropriate deworming agents, mainly with high efficiency and low toxicity, such as avermectin, avermectin and so on. The toxicity of these agents is very low, and can control all kinds of parasites, has a strong killing effect. But it is important to note that these agents cannot kill the eggs. Because if the efficacy and toxicity is strong, then the pregnant sheep will cause great harm, prone to abortion, stillbirth and other adverse phenomena, so we must pay more attention.

2. Drug use

The time of deworming of pregnant sheep must be well controlled, and the number of deworming should be kept at about twice a year. It is generally carried out in spring and autumn, because spring and autumn is the season with high incidence of parasites, and ewes are also vulnerable to parasites. Then when we carry out deworming, we should carry out prenatal deworming before the pregnant sheep give birth. To prevent the occurrence of fecal worm eggs in 1-2 months postpartum, resulting in postpartum increase in ewes. If the parasite damage is more serious, then the postpartum deworming work should be carried out in the ewe about one month after delivery.

3. Use dose

There are many ways of deworming, such as injections, powders and tablets. If the injection is used, it must not be injected intramuscularly or intravenously, but mainly subcutaneously to avoid affecting the growth of ewes. According to the weight to control the pigsty dose, generally about 10 jin injection 0.7 mg. If it is the use of powder deworming, then to take, mix mainly, every 10 jin of the dosage is maintained at about 1 mg. Finally, if the tablet is taken internally, then the dosage is the same as the powder.

4. Points for attention

When we are deworming, we must pay attention to control the amount of insect repellent. For ewes that are not pregnant, the dosage can be increased appropriately. Ewes with insect repellents should not be eaten immediately and should not be eaten until about two weeks later, while goat milk can only be drunk after about three weeks. If there is an extracorporeal parasite, use the drug again a week after deworming. After deworming, it is necessary to do a good job in the sanitary work of the sheep house and regularly deal with sheep excrement to avoid the breeding of parasites and germs again.

The above is a brief introduction to the deworming methods of pregnant ewes. If parasitic diseases do not occur in the area or are already sporadic, try not to deworm pregnant sheep, preferably after the end of the lactation period. That's all for today's introduction.
