n = number of ducks used in quality analysis; pH15 = 15 min post-mortem; pH24 = 24 h post-mortem; L* = lightness; a* = redness; b* = yellowness.

1

Each value represents the mean of four replicates (two ducks per pen).

2

1 = feed based on soybean meal, 2 = feed based on yellow lupin; values are means.

a,bColumns marked with different letters differ significantly between groups, P-value <0.05.
