Sheep are one of the most numerous farm animals globally; their welfare across wool, dairy, and meat production systems varies enormously.
Sheep in well-managed extensive systems have relatively good welfare: outdoor access, flock social structure, and natural grazing. Intensively housed sheep face lameness from inappropriate flooring, mastitis from high milk production demands, and foot rot from wet conditions. Separation from flocks causes acute stress measurable in cortisol and vocalization. The variation in sheep welfare standards globally is enormous.
