The primary use of a twitch in horses is to calm aggressive behavior. A twitch is a device applied to the upper lip or other sensitive areas of a horse to create a mild distraction and induce a state of calmness. This action helps to alleviate anxiety and allows the handler to perform necessary procedures, such as veterinary examinations or grooming, in a safer manner. The pressure applied by the twitch stimulates endorphin release, which can help reduce the horse's stress levels and make it more manageable during potentially uncomfortable situations.

The other options do not accurately reflect the primary purpose of a twitch. While there may be instances where a twitch could assist during transportation by keeping the horse calmer, that is not its primary function. Retraining horses, although potentially related, involves more comprehensive training techniques that address behavioral issues, rather than relying solely on the temporary restraint of a twitch. Lastly, increasing a horse's speed is unrelated to the use of a twitch, as this device does not enhance performance or speed but focuses more on modifying behavior during handling or treatment.
