Zero-grazing systems confine cattle indoors year-round. Understanding the welfare implications helps evaluate these systems against outdoor alternatives.
Total confinement of cattle eliminates access to grazing, natural light, varied terrain, and the behavioral diversity of outdoor environments. Research demonstrating cattle preference for outdoor access when given choices confirms that confinement represents a welfare restriction even when health outcomes are maintained. Cattle in well-managed indoor systems may be physically healthy while experiencing behavioral deprivation from the absence of grazing, running, exploring, and social interactions possible in larger outdoor spaces. The welfare debate is not simply about health outcomes but about the quality of daily experience that confinement versus pasture provides.
