BW – Body weight, DWG – daily weight gain, FI – feed intake, GE – gross energy,
CON – Control diet, SCLA – diet with 1.69% synthetic CLA replacing and equivalent amount of soybean oil, CONM – Diet containing control beef (see table 1), CLAM – diet containing high CLA beef (see table 1).
Protein intake – product of diet protein content and FI overall/100.
GE intake – product of diet GE and FI overall.
Consumed CLA c9, t11 or CLA t10, c12 – calculated from means, CLA c9, t11 or CLA t10, c12 percent in diet × diet fat content × FI overall/10000; respectively.
