^a,bMeans within a row with no common superscript differ when P < 0.05. n = 6.

Abbreviation: FCR, feed conversion ratio.

¹Control, diet 1, and diet 2 represent corn-soybean meal-based diets containing 0% microalgae (control), 2% microalgae (diet 1), and diet 1 + 100% more methionine (diet 2).

²Breast muscle weight (g) is reported with bones and without skin in samples collected at day 45 of feeding.
