Monitoring pig body condition throughout the production cycle is a fundamental welfare practice that identifies animals that are too thin or too fat, both of which indicate welfare problems requiring management intervention.
Body condition monitoring is a welfare tool that translates visible physical indicators into actionable management information. A thin sow is not merely an aesthetic concern but evidence that the animal has been burning protein and fat reserves to meet metabolic demands that her intake cannot satisfy. This chronic energy deficit involves sustained physiological stress and increasing vulnerability to disease. Identifying thin animals early through regular condition scoring allows targeted nutritional intervention before conditions become severe. In group-housed sows, thin individuals may indicate inadequate trough space, competitive exclusion by dominant animals, or disease affecting feed intake. Systematic body condition monitoring across the herd provides a welfare early warning system that, when combined with responsive management, prevents welfare problems from developing into welfare crises.
