ABSTRACT
Three trials were conducted to examine the effect of including specific amino acids, fatty acids, and fat sources in 20 and 22% CP and 20% fat milk replacers (MR; as-fed) fed at 454 g daily. Trial 1 measured selected blood constituents in calves fed a 20% CP, 20% fat MR including all added fat from lard and no added synthetic amino acids (CON20); a MR with added butyrate (BUT20); a MR with added coconut plus canola oil (FB20); and a MR with added L-Lys plus DL-Met (LM20). Trial 2 compared CON20, LM20, and a MR with 22% CP (CON22). Trial 3 compared CON22, a MR with 20% CP with added Lys and Met, 20% lard, coconut, and canola fat with sodium butyrate (MOD20), and pasteurized whole ...
