At weaning, place ewes on poor quality hay and withhold water for 24 hours to help stop milk production and reduce mastitis problems. Cull ewes and market barren producers. Use your records. Market lambs either as feeders or finished lambs when they reach appropriate size and weight. Observe condition of ewes - don't allow them to get overly fat or too thin.
Heavier ewes require more feed.
At all times provide ewes with a salt-mineral mix that contains selenium to meet the requirements for selenium in your area.
