Safety Savvy - Cattle—Handle With Care |

Methods of handling cattle by Dan West In the United States, large animals are involved in many serious non-fatal injuries to farmers, and cattle are responsible for a majority of all injuries caused by farm animals. Studies have shown that more than half of the animal-related injuries were due to human error. Understanding cattle's behavior can often help farm workers avoid dangerous situations. Cattle have panoramic vision, which means they can see in nearly all directions without moving their head, except directly behind them. Additionally, cattle have poor depth perception, especially when they are moving with their heads up. This is why they sometimes balk at shadows and strange objects on the ground. Unfamiliar objects and shadows are the primary reasons for cattle balking and holding up the animals behind them. Therefore, handling and working facilities should be designed and constructed to minimize shadows. Cattle have a tendency to move out of darkness toward lighter, brighter areas. If working with cattle at night, use frosted light bulbs that do not glare in the animals' faces. Positioning these lights in the area where you are moving the cattle to, such as a trailer or barn, will encourage them to go in that direction. Safely moving a herd of cattle takes some knowledge and understanding of the animals' "flight zone." Understanding the flight zone is the key to easy, quiet handling of your cattle. Think of the flight zone as an animal's personal space. When someone moves into the flight zone, the animal will move away. Conversely, when you move away from the flight zone the animal will stop moving. The size of an animal's flight zone depends on its wildness or tameness, the angle of approach, and the state of the animal's excitement. Work at the edge of the flight zone at a 45 to 60 degree angle behind the animal's shoulder which is its pivot point. The flight zone radius varies greatly depending on the amount of contact with people the animal has had. Moving back and forth by the animal's shoulder, at the edge of the flight zone, on a line parallel to the direction you want the animal to travel will control the animal's speed and direction. Avoid approaching the animal abruptly. In addition to the flight zone, an understanding of the "herd" instinct is important. Cattle like to be in a group and follow a leader. They follow each other. Each animal should be able to see others ahead of it. Use single-file alleys and chutes at least 20 feet long. Don't force an animal in a chute or alley unless it has a place to go. If a cow balks, it will continue balking. Give it time to decide its surroundings are safe before urging it to proceed. In crowded pens, consider handling cattle in small groups—up to 10 head. The pen should not be so crowded that the cattle do not have room to turn. Use their instinctive following behavior to fill the chute. Wait until the single chute is almost empty before refilling it. A crowding gate should be used to follow cattle, not to shove up against them. If a lone animal refuses to move, release it and bring it back with another group. A cow left alone in a crowding pen may become agitated and attempt to jump the fence to rejoin the herd. Remember
Whether you work with beef cattle or dairy cows, these methods of handling them can make your work safer and less frustrating. For information on other farm safety and health issues call NYCAMH at 800.343.7527 or 607.547.6023. |
