Sheep are also considered colorblind, but do have good depth perception. Instead, sheep have difficulty picking out small details, such as the open space created by a partially opened gate. Cattle, horses and mules have a panoramic field of vision, which means they can see everything around them except what is immediately behind their hindquarters. Therefore, approaching from the side or front can be less startling to these animals than approaching from behind. Horses and mules commonly kick toward their hindquarters, while cows kick forward and out to the side.
Cows also have a tendency to kick toward a side with pain from inflammation or injuries.
For example, if a dairy cow is suffering from mastitis in one quarter, consider approaching her from the side of the non-affected udder. Livestock with young exhibit a maternal instinct. They are usually more defensive and difficult to handle. When possible, let the young stay as close to the adult as possible when handling. They develop a very distinctive, comfortable attachment to these areas.
