¹FOD = basal diet + 2% fish oil; SOD = basal die + 2% soybean oil; FODs = basal diet + 2% fish oil + 370 g/d SP; SODs = basal diet + 2% soybean oil + 370 g/d SP.
²SEM = standard error of the means, Tr = treatment.
³ECM: Energy-corrected milk = (kg of milk×0.3246) + (kg of milk fat×12.96) + (kg of milk protein×7.04).
^a–cMeans within a row with different superscripts are significantly different (P < 0.05).
