Meat lightness and redness in fresh samples and after storage were
similar in all groups, but yellowness was much lower (P ≤ 0.05) when
the herbal extract was used than in animals receiving BHT. Greater
color stability (lower ΔE) was found in meat of pigs fed with herbal extract
than in controls (P ≤ 0.05). Barrow meat was significantly brighter
(P ≤ 0.05) after storage than that of gilts.
