ABSTRACT:
A zinc bacitracin composition for use as a feed supplement which possesses improved stability to heat, mechanical mixing and moisture when used in substantially dry animal feeds. Zinc bacitracin is precipitated by the addition of zinc cations, as in the range of between 0.5 to 0.7 g Zn++/g bacitracin to a bacitracin fermentation broth. Finely divided carrier material, such as calcium carbonate, is then added to the extent of 50 to 100 weight percent based on the dry matter, and the mixture is agitated to get a uniform mix. The uniform mixture is then spray dried to produce substantially spherical particles of the zinc bacitracin composition.
