What is the primary purpose of a snubbing rope in veterinary practice?

The primary purpose of a snubbing rope in veterinary practice is to assist in restraining a pig's head. This tool is specifically designed to provide a safe and effective means of control during veterinary examinations or procedures, particularly with large or unruly animals like pigs. By facilitating better control over the animal's head, the snubbing rope helps ensure the safety of both the animal and the veterinary staff. It allows for necessary examinations or treatments to be performed without causing undue stress to the animal or risking injury to the personnel involved.

The other choices, while presenting plausible scenarios in a veterinary context, do not align with the specific function of a snubbing rope, which is focused on head restraint rather than securing equipment or transporting supplies.
