1, there is no one, deworming drugs are universal
Many people think that after using ivermectin (or avermectin), everything is fine. Although it is a broad-spectrum anthelmintic drug, it is not effective for all parasites and is ineffective for tapeworms, trematodes and protozoa. There is no one kind of anthelmintic drugs is universal, should be based on the actual situation of cattle farms using different anthelmintic drug staging or joint practical.
2, ivermectin, not intramuscular injection
Ivermectin (or avermectin) can only be taken orally, subcutaneously, or externally, but many people give it intramuscularly. This approach is wrong. First of all, poor absorption cannot have a better deworming effect. Second, it is more irritating to cattle, and cattle will have a strong sense of pain. Finally, the injection site is prone to suppuration.
3, ivermectin skin, injection effect is better
Many people like to use ivermectin (or avermectin) as a mixture because it is more convenient. But ivermectin is not soluble in water in the gastrointestinal absorption is not as good as subcutaneous, and there are more unstable factors for oral administration, so the effect of subcutaneous injection is better. It is recommended that conditional cattle farms should also take the form of subcutaneous injection.
4. Pregnant cow, deworming
Although many anthelmintic drugs are available in pregnant animals, they still need to be cautious. Because the toxicity of injection and insect repellent can cause abortion of cattle, it is better to adjust the insect repellent time to the empty pregnancy period of cows, especially before pregnancy.45 days before delivery30Day must avoid the use of deworming drugs.
5. First small group experiment,Large group again
In order to avoid poisoning or other problems caused by incorrect dose calculation, a small amount of cattle should be dewormed first, etc.1~2 days without any problems on the whole herd of cattle deworming.
6. The key to deworming is not medication but environment
In the case of poor hygiene, it is very conducive to the spread and growth of parasites. Therefore, the key to deworming is not medication, but to do a good job in the sanitation and disinfection of cattle houses to give cattle a good living environment. Especially during the deworming period, we must do a good job in the sanitation and disinfection of the cowshed to avoid the eggs left in the cowshed to continue to cause infection to the cattle.
7, can not be excessive, use
Now there are more unqualified anthelmintic drugs on the market, used5 times even.10Double the dosage has no effect. Many people have developed the habit of super-practical anthelmintics, but in case they buy qualified anthelmintics, they will be in trouble. Because most anthelmintic drugs have strong toxicity, excessive use of the case is very easy to cause poisoning. Considering the liquid medicine left in the syringe or the loss of liquid medicine due to other reasons, it is generally necessary to exceed the stated dosage, but the maximum dosage shall not exceed the stated dosage.1.2Times. Eligible anthelmintic drugs in excess of the stated dosage1.5Poisoning may occur. Everyone must remember that it is better to use less and be ineffective than to be poisoned in excess.
