The data for lightness and yellowness are not presented. When analysed for dietary effects using time as individual days, there was no interaction of Flax × Algae (P N 0.05) found for lightness, yellowness, redness or brownness formation for any of the days. However, there were main treatment effects observed only on day 4 of display, where lambs fed the algae diet (average of Algae and FlaxAlgae treatments) had lower redness at day 4 of display (P b 0.05; 12.8 vs 13.4, SED = 0.19) than lambs fed without algae (average of Basal and Flax) in the diet, but brownness formation was not affected.
