Abstract

Effects of vitamin/mineral nutritional modulation, preslaughter stress, and hot-fat trimming (HFT) on traits of 60 market hogs carrying one mutated copy of the halothane gene were determined. Both supplemented treatments resulted in more backfat over the longissimus muscle (P < 0.05) and darker Hunter L* values for the semimembranosus muscle (P < 0.05). Purge from the vacuum-packaged loin sections during 7 days of storage at 2C was reduced. Supplemented treatments had lower Hunter L* readings for the semimembranosus muscle (P < 0.05). Treatments did not affect muscle palatability. Shelf-life, water holding capacity and color of muscle was improved in chops from supplemented pigs (P < 0.05). HFT and transporting pigs for an additional 2 h did not affect meat quality. This study demonstrated advantages for improving pork muscle quality from pigs fed the vitamin/mineral supplement for at least 4 weeks before slaughter of market pigs monomutant for the halothane gene.
