Final answer:
The neck is the proper injection site for vaccines and therapeutic medicines in cattle.
Step-by-step explanation:
The statement is true. In cattle, the neck is indeed considered the proper injection site for vaccines and therapeutic medicines. This is because the neck region provides easy access to the muscles and blood vessels, allowing for efficient absorption and distribution of the injected medication.
When injecting cattle, it is important to choose the correct site to minimize the risk of complications such as abscesses or damage to nerves or blood vessels. The neck is a commonly recommended injection site due to its large muscle mass and low risk of interference with milk or meat production. The neck area is chosen to prevent damage to valuable cuts of meat and to reduce the risk of causing tissue damage that can interfere with the movement and well-being of the animal. This is in contrast to humans where the common injection site for vaccines is the upper arm.
