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.

Zinc bacitracin is precipitated by the addition of zinc cations, as in the range of between 0.5 to 0.7 g Zn.sup.++ /g bacitracin to a bacitracin fermentation broth, and then concentrated to 25 to 35% dry matter. 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.

Abstract: A proteinaceous aqueous sludge, previously precipitated with a precipitating agent, is mixed with calcium chloride, and treated with a base selected from the group consisting of alkali metal hydroxides and alkaline earth metal hydroxides to adjust the pH to a value in the range of 6.5-9.5. The mixture is then heated to a temperature in the range of 60.degree.-120.degree.C. to coagulate and agglomerate the sludge, which is then separated from the aqueous phase containing the precipitating agent.
