What document is required for livestock movement into California?

The requirement for livestock movement into California includes several essential documents to ensure the health and safety of animals as well as to comply with state regulations. An interstate livestock entry permit is necessary as it authorizes the transport of the livestock across state lines and helps state authorities track and manage movements for health and regulatory purposes.

A health certificate is also a prerequisite; it is an official document from a veterinarian stating that the animals are free from disease and fit for entry into California. This certificate generally needs to be issued shortly before transport to ensure accuracy regarding the health status of the animals.

Additionally, a certificate of veterinary inspection (CVI) within a specific timeframe, such as within 30 days of entry, is typically required as this document also verifies the health and condition of the livestock being moved into the state.

The necessity of all these documents underscores the importance of maintaining animal health standards during interstate transport and aligns with California's regulations to protect its livestock population and agricultural environment. Thus, all of the listed documents work together to ensure compliance and safety, making the correct answer comprehensive in encompassing all the required documentation.
