Bacitracin-MD and zinc bacitracin at 0, 10, 20 and 40 g per ton levels were individually added to a 13.2% protein low density mash diet (Table 1). In addition, the control and diets containing 40 g of antibiotics per ton were pelleted to investigate the effects of antibiotics and/or pelleting on egg production parameters and feed consumption. Twelve 24-week old pullets were initially used for each treatment replicated eight times using randomized complete block designs. Feed and water were provided ad libitum.
