Abstract
1. No evidence was found for an interaction between dietary crude protein content and the presence or absence of two proprietary food additives used as sources of avoparcin and zinc bacitracin.
2. The food additives had a similar effect in increasing rate of growth resulting in significant improvements of about 2% in the food conversion ratios.
