Preliminary Research on Dietary Supplementation of Potassium Magnesium Sulphate on Transport Stress in Finishing Pigs Prior to Slaughter
Abstract
Simple Summary Transport stress prior to slaughter frequently induces a stress response, compromising meat quality. The aim of this study was to investigate the effect of dietary potassium magnesium sulphate (PMS) supplementation during the fattening stage on the stress response and meat quality in finishing pigs subjected to a transport challenge prior to slaughter. Our findings indicate that while dietary PMS supplementation did not affect growth performance during the fattening period, it significantly enhanced antioxidant capacity and meat quality. In the transportation model, PMS supplementation significantly improved the antioxidant capacity, stress response and meat quality of finishing pigs. These results suggest potential applications of PMS in the livestock industry to enhance animal welfare and meat quality.
