Diets used in this study included the following: 1) unmedicated corn-soybean meal (SBM) basal without SDP (Control diet); 2) unmedicated corn-SBM basal into which bacitracin methylene disalicylate (BMD) was added at 0.055 g/kg diet (BMD diet); and 3) SDP diet in which spray-dried plasma was incorporated into unmedicated corn-SBM basal at 3% level (i.e., 30 g/kg diet). Each of these 3 diets were separately formulated for the starter (D 1 to 14), Grower (D 15 to 28), and finisher (D 29 to 42) phases of broiler production cycle.
