^a,bLeast square of means within a row without a common superscript letter differ (p<0.05).

¹Each least squares mean represents 4 pens with 2 birds sampled per pen.

²Fatty acids were denoted by the number of carbons: number of double, followed by the position of the first double bond. SFA, saturated fatty acid; MUFA, monounsaturated fatty acid; PUFA, polyunsaturated fatty acid.

⁴The number of days in the parenthesis represents each experimental period.
