What does "bitting" refer to in horse training?

Bitting refers specifically to the process of selecting and using a bit as a tool for communication between the rider and the horse. This involves understanding the various types of bits available and how they function to influence the horse's movements and behavior. A properly fitted bit that aligns with the horse's level of training and sensitivity can enhance communication, making it easier to give cues and commands.

The other choices represent different aspects of horse care and training but do not accurately define bitting. The method of training a horse to jump relates more to jumping techniques and skills rather than communication tools. Feeding a horse for optimal performance is crucial for overall health and performance, but it falls under nutrition rather than bitting. Cleaning a horse's bit after use is an important maintenance task for ensuring hygiene and longevity of the equipment, yet it does not encapsulate the broader concept of bitting itself. By choosing the correct answer, one demonstrates an understanding of how bits are used as instruments of communication in horse training.
