¹The dietary treatments were based on the total mixed ration (TMR) with varying protein contents as follows: CON = control TMR without soymilk residue, SSR-50 = TMR with 50% of the SBM was replaced by soymilk residue, and SSR-100 = TMR with 100% of the SBM was replaced by soymilk residue. SBM = soybean meal; SSR = sundried soymilk residue; DM = dry matter; OM = organic matter; CP = crude protein; EE = ether extract; NDF = neutral detergent fiber; ADF = acid detergent fiber.
