A.S. Series 79-19
With the current concern over the use of antibiotics in poultry feeds, greater interest is being given to antibiotics which are not absorbed into the blood stream. Bacitracin is one of that type being considered and actually is in extensive commercial use.
Previous studies at this station showed Bacitracin-MD to improve production of laying hens fed a low density diet with the antibiotic at levels of 10, 25 and 50 grams per ton (see A.S. Series 77-21). No responses were obtained with the 100-gram per ton level or any level when supplementing a high density diet. In addition, bacitracin has been used routinely at this station in growing turkey diets.
