A study looked at how the way grass and clover are arranged in a field affects how much sheep eat. They found that sheep eat more white clover than grass, especially in spring. The height of the plants in the field also affects what the sheep choose to eat. Even small differences in height can make a big difference in what the sheep graze on. The way the plants are mixed together horizontally doesn't seem to matter as much as their height. Overall, the arrangement of grass and clover in a field can change what sheep choose to eat.
