These requirements may include; blood work, vaccinations, permanent identification, USDA health certificate, and entry permit number. There may also be a quarantine requirement. Ask for specifics and get that in writing so you may share it with your vet. Some of the blood work requirements may not be mandatory if your herd has been tested for the year. Ask questions and make notes. The information can vary from person to person, office to office, and state to state.
Please remember that the USDA or APHIS requirements are completely separate and unique to the airline requirements. You must comply with the USDA first, and the airline second for legal shipping into another state.
Ground shipping that crosses state lines will need the same USDA/APHIS requirements be met. A ground transport company may have separate and unique requirements that should be met second to the USDA.
