Bedding materials significantly affect pig welfare by enabling rooting behavior, providing thermal comfort, and reducing leg and skin problems.
Bedding is not a luxury for pigs but a fundamental welfare provision. Straw meets multiple welfare needs simultaneously: rooting substrate, thermal insulation, and absorptive material. Systems that eliminate bedding for management convenience impose chronic welfare costs on the animals. Investing in bedding as a core welfare provision rather than an optional extra would transform pig welfare in commercial systems.
