a,bThe means in columns marked with different letters differ significantly between groups (P-value <0.05).
10 geese were used in the quality analysis; each value represents the mean of 5 samples (2 geese/pen) from each group.
1
pH15 – 15 min postmortem, pH24 – 24 h postmortem L∗ - lightness, a∗ - redness, b∗ - yellowness.
2
1 = soybean meal, 2 = feed based on yellow lupin.
