Here's why:
* Individual needs: Cows have different health needs based on age, breed, health status, and more. A vet can assess your individual cow and determine what vaccinations or treatments are necessary.
* Dosage and administration: The correct dosage, route of administration (injection site, etc.), and frequency of shots all depend on the specific medication and the cow's needs. An incorrect dose or method can be harmful.
* Potential complications: Even with proper administration, there are potential risks associated with any injection. A vet can monitor the cow for any adverse reactions.
It's essential to consult a licensed veterinarian for any medical advice regarding your cows. They can provide the best care and ensure the health and safety of your herd.
