Access to nutritionally adequate, palatable feed is a fundamental welfare requirement for livestock, with feed restriction, poor quality, and competition for access all causing welfare harm.
Feed welfare encompasses access, quality, and competition dimensions. Animals denied adequate access to appropriate feed are in a state of hunger — a primary negative welfare state. Feed restriction programmes in breeder animals cause sustained hunger motivation that is chronically frustrating. Competition at feed barriers in group-housed animals means that stocking density relative to feed space determines whether all animals receive adequate nutrition. Feed quality affects metabolic health: poor-quality, unbalanced diets cause subclinical disease states that compromise both welfare and productivity. Good feed management addresses all three dimensions simultaneously.
