Producers use ractopamine and porcine somatotropin (pST) pre-slaughter to improve growth performance and carcass composition. This project aimed to determine the interaction of ractopamine, pST and moisture infusion post-slaughter, and examine the interaction between ageing and moisture infusion, on sensory pork quality. These findings indicate that ractopamine supplementation or pST pre-slaughter did not interact with moisture infusion post-slaughter to improve the sensory quality of pork. Moisture infusion improved sensory pork quality to a greater degree than ageing. Therefore, processors can use moisture infusion to improve sensory pork quality, particularly when the supply chain does not allow sufficient ageing time.
