Lipid oxidation was lower (P < 0.001) after 4 d of storage in fresh ground pork from pigs fed 200 and 400 IU of VE/kg of feed compared with pork from pigs fed 40 IU of VE/kg of feed (Table 2). Fresh ground pork had lower TBARS values in the long-term feeding periods (6 and 9 wk) than pork patties from pigs fed 3 wk of VE diets after 4 and 6 d of chilled storage (P < 0.001).
No interaction was observed between VE level and feeding duration for fresh ground pork patties.
