What is the primary use of a syringe in cattle management?

The primary use of a syringe in cattle management is to administer medicine. This can include vaccinations, antibiotics, hormones, or vitamins that are essential for maintaining the health of the cattle. By using a syringe, a precise dosage can be delivered directly into the animal, ensuring that it receives the necessary treatment effectively and quickly. This method is crucial for disease prevention and treatment, promoting overall herd health and productivity.

While there are various roles for the other choices in cattle management, their functions do not align with the primary purpose of a syringe. Supplemental feed is typically given through feeding equipment, identification of animals involves tags or other markers, and castration is performed through surgical methods rather than using a syringe. Each of these methods serves important functions in cattle management, but administering medicine is specifically what a syringe is designed for.
