The data are percentages. Different amounts of CNSL were fed in Run 1 (4 g/100 kg BW) and Run 2 (6 g/100 kg BW). Feed without CNSL was fed to cattle as control period 1, and CNSL was fed to the cattle for periods 3 and 4. The detailed experimental schedule can be found in Figure S1. Different superscript letters indicate that the means are significantly different between the periods (P < 0.05). CP, crude protein; DM, dry matter; EE, ether extract; GE, gross energy; NDF, neutral detergent fibre; OM, organic matter.
