Ivermectin Injection for Cattle: What You Have to Know

1. Overview of Ivermectin Injection for Cattle

Ivermectin injection is a widely used parasiticide for cattle, effective against a variety of internal and external parasites. It is particularly important in maintaining the health of cattle herds by controlling harmful species that can impair their well-being.

 

2. What Parasites Can Be Treated in Cattle by Using Ivermectin Injection?

It is effective against a range of internal and external parasites, including gastrointestinal roundworms (including inhibited Ostertagia ostertagi), lungworms, grubs, sucking lice, and mange mites in cattle.

 

3. How Does Ivermectin Work in the Body of Cattle?

Ivermectin primarily acts by binding to specific glutamate-gated chloride channels located in the nervous systems of parasites. This binding induces hyperpolarization of the nerve cells, leading to paralysis and eventually the death of the parasite.

In addition to its action on glutamate-gated chloride channels, ivermectin also affects other ion channels, such as gamma-aminobutyric acid (GABA) receptors. These receptors are crucial for the normal functioning of the nervous system in parasites.

The disruption of these channels further contributes to the drug’s effectiveness by incapacitating the parasites’ ability to control their movement and feeding behaviors and eventually kill them.

 

4. What Are the Benefits of Using Ivermectin Injection for Cattle?

Among the key parasites targeted by ivermectin injection are gastrointestinal nematodes, which can severely impact cattle by causing weight loss, reduced feed efficiency, and overall poor health. External parasites such as lice and mites are also effectively managed, preventing secondary infections and irritation.

Furthermore, by reducing the parasitic burden, it helps improve the overall well-being of the cattle, leading to better weight gain, increased milk production, and enhanced reproductive performance. This, in turn, has positive economic implications for farmers, making ivermectin injection an essential component of effective cattle herd management strategies.

 

5. What are the Administration and Dosage of Ivermectin Injection for Cattle?

It should be given to cattle only by subcutaneous injection in front of or behind the shoulder.

The recommended dosage is 1 ml per 110 lbs of body weight (maximum 10 ml per injection site).

 

6. Can Ivermectin be Injected Intramuscularly into Cattle?

No. This practice is wrong. First, it is poorly absorbed and cannot have a good deworming effect. Second, it is highly irritating to cattle, and cattle will feel strong pain. Finally, suppuration is easy to occur at the injection site.

 

7. What will Influence the Dosage of Ivermectin Injection for Cattle?

Factors influencing dosage adjustments include the age, weight, and health condition of the cattle. For example, younger or debilitated animals may require different dosages compared to healthy adults.

Additionally, factors such as the severity of the parasitic infestation and the presence of other health issues may necessitate adjustments to the standard dosage.

Finally, do not underdose. Ensure each animal receives a complete dose based on a current body weight. Underdosing may result in ineffective treatment, and encourage the development of parasite resistance.

 

8. What are the Adverse Reactions of Ivermectin Injection for Cattle?

There are several adverse reactions after administration, such as swelling at the injection site, allergic reactions, or neurological symptoms.

 

9. After the cow gave birth, Ivermectin was injected. After the injection, I found that it was written on the medicine box that it was forbidden to use during lactation. Do I need to stop the calf from feeding?

Ivermectin injection is one of the more commonly used anthelmintics, which has a good killing effect on nematodes and arthropods. Injection of ivermectin to lactating cows generally does not have much impact on calves, so there is no need to stop the calf from feeding.

The prohibition of ivermectin during lactation is mainly for dairy cows, because ivermectin takes a long time to metabolize in the body of cows, and there will be residual ivermectin in the milk that cannot be sold. It takes more than 20 days after stopping the drug to detect ivermectin in the milk.

 

10. Is there a Withdrawal Period for Treated Beef Cattle?

Yes. There is usually a withdrawal period before the meat or milk from treated cattle can be safely consumed. This period can vary, so it’s crucial to check the label instructions or consult a veterinarian.

 

11. How Can Ivermectin Injection Be Stored and Handled?

Store the ivermectin injection solution as recommended by the manufacturer, typically in a cool and dry place away from light.

Besides, check the expiration date before use and do not use expired products as they may not be effective or could be harmful.

 

Conclusion

Taking these tips when using ivermectin injections in cattle not only ensures the health and safety of the animals but also protects the environment and public health. If you have other questions, welcome to consult Gnee Bio.
