Herd and flock health management programs aim to prevent disease at the population level but must be designed to minimize welfare cost of interventions and maximize early treatment.
Herd health management welfare is about the quality of attention given to individual animals within population-level programs. Farmers who know their animals, can recognize early signs of disease, and have rapid access to veterinary advice achieve better welfare outcomes than those relying on periodic veterinary visits. Digital health monitoring tools are extending the reach of veterinary oversight in large operations. The transition from reactive to preventive health management is the highest-leverage welfare improvement available in most livestock systems.
