Each livestock species expresses pain differently — species-specific pain recognition knowledge is essential for prompt intervention that prevents prolonged suffering.
Pain recognition across livestock species requires species-specific knowledge because each has evolved different pain expression strategies based on its ecology and social structure. Sheep, as highly prey animals, mask pain particularly effectively — a lame sheep continues to feed until it is severely impaired. Pigs vocalise pain but their calls are so routine in farm environments that abnormal distress calls go unnoticed without listening education. Cattle facial expression changes require proximity and training to detect. Validated pain scales for each species are now available and translate this species-specific knowledge into practical assessment tools that stockpersons can use without specialist training.
