  1. L* = lightness; a* = redness; b* = yellowness. Warner-Bratzler shear force (WBSF), Newton (N). Intramuscular fat (IMF) (%). #pH recorded at 45 minutes post mortem. @Drip loss obtained by hanging muscle on day 1 post mortem for 48 hrs according to method of Honikel et al. [25]. Significant values are indicated in italics. Within rows, for day 1 to day 7 comparisons means which do not share a common superscript are significantly different.
