Sheep have numerous uses on a smallholding. They are excellent grazers and are ideal at revitalizing old pastures as well as an excellent follower of the cows in a rotational grazing system. Cropping the grass at 2-3 inches that the cows have left at 8 inches encourages new growth in the spring. Their manure is usually in pellet form and is spread throughout a pasture as they graze. A sheep shares a ton a year of fertilizer with the earth.
