Stockperson attitudes and handling styles are among the most powerful determinants of pig welfare, with positive stockpersonship producing measurably better outcomes.
Stockperson attitude and behavior is arguably the single most important determinant of pig welfare on commercial farms — more important than housing system, space, or even enrichment. Pigs handled by people who use aversive techniques including hitting, kicking, and shouting develop chronic fear that permeates every aspect of their welfare. The welfare and productivity evidence for positive stockpersonship is mutually reinforcing: fearful pigs grow slower, have more health problems, and are harder to manage. Training programs that address both behavior and underlying attitudes produce the most durable welfare improvements.
