What are the effects of pen strep on pregnant cows?

Penicillin-streptomycin (pen-strep) can be used in pregnant cows to treat bacterial infections, but it should be administered cautiously. While it can effectively combat infections, there is a risk of adverse effects on the fetus, including potential disruption of normal development. It's important for veterinarians to evaluate the benefits versus risks and consider the stage of pregnancy when prescribing this antibiotic. Always consult with a veterinarian for the best treatment plan for pregnant cows.
