Sheep should be kept in adequate pasture. For basic ewes, a large amount of stocking exercise is beneficial to estrus mating of ewes and reduces dystocia rate, and ewes are not easy to lack nutrition and vitamins because of the overgrown grass on the grassland. According to the physical condition of ewes and the length of pregnancy, concentrated feed can be supplemented after grazing. For fattening lambs, if the pasture is nearby, grazing and house feeding can be combined. If the pasture is far away, the lambs have a large amount of exercise and are not suitable for grazing. It is best to fatten them in the house.
