¹The dietary treatments were based on the total mixed ration (TMR) with varying protein contents as follows: CON = control TMR without sundried soymilk residue, SSR-50 = TMR with 50% of the SBM was replaced by sundried soymilk residue, and SSR-100 = TMR with 100% of the SBM was replaced by sundried soymilk residue. SEM = standard error of the mean; DM = dry matter; BW = body weight; BW^0.75 = metabolic body weight; CP = crude protein; OM = organic matter; NDF = neutral detergent fiber; ADF = acid detergent fiber. ^a–cMeans in the same row with different letters differ ().
