FFA = free fatty acids; S = soybean; P = palm; BW = body weight; ADFI = average daily feed intake; FCR = cumulative feed conversion ratio.

^a-c Means within each variable with more than 2 levels (experimental diet or FFA content) not sharing a common superscript differ according to Tukey's test (P < 0.05).

Pooled standard error of the means.

Linear responses to dietary FFA content.
