Restrictions on transporting cattle, sheep or goats with injured or diseased udders
Do not transport an animal with an injured or diseased udder (mastitis), or lesions on her udder. If your animal has signs of mastitis, including inflammation or discharge, she is not fit for transport.
The exception is for a short distance, for treatment. Consult your veterinarian if you are unsure if your animal is fit for transport. FINE: $500
