There are several controls we can implement to reduce the risks associated with livestock management:  

• First! Study animal behaviour. This will improve your ability to anticipate and manage potential risks.
• Learn to ride. The better trained the rider, and the better trained the horse, the stronger and more effective the working relationship.
• Be patient when working with livestock.
• Use correct livestock handling techniques.
• Be quiet. Loud noises tend to spook animals.   
• Ensure all gates are in good working condition, and kept securely closed.
• Avoid working with animals in confined spaces (e.g., chutes).
• Give animals lots of space when herding them. When available, use support animals (e.g., dogs) to help. This increases the space between you and the livestock.
• Avoid slippery work areas. These are potentially hazardous to both man and beast.
