It is extremely dangerous to administer any medication without consulting a veterinarian.
Here's why:
* Dosage is critical: The correct dosage depends on the medication, the cow's weight, and its health condition. Getting the dosage wrong can be fatal.
* Drug interactions: Some medications can interact dangerously with others. A vet can ensure the medication is safe for your cow given its current health status and any medications it may already be taking.
* Underlying conditions: Your cow could have an underlying condition that makes certain medications unsafe or requires a different dosage.
Please contact your veterinarian immediately for advice on how to treat your cow. They will be able to assess your cow's condition and provide you with the proper dosage and instructions.
