The milk replacer has a pH of about 5.8 and the concentration of percarbonate is effective to reduce bacterial growth within the milk replacer product. The milk replacer can also include at least one added organic acid. ## Claims ### Claim 1 A method of feeding livestock animals, the method comprising: feeding the livestock animals a milk replacer comprising an antibacterial system consisting of percarbonate and at least one added acid selected from a group consisting of: citric acid, malic acid, valeric acid, acetic acid, propionic acid, butyric acid, formic acid, caproic acid, oxalic acid, lactic acid, benzoic acid, carbonic acid, phosphoric acid, hydrochloric acid, sulfuric acid, succinic acid, tartaric acid, fumaric acid, adipic acid, gluconic acid, pyrophosphoric acid and carbolic acid, wherein the milk replacer has a reduced pH of about 5.8, wherein the milk replacer exhibits reduced growth of Salmonella over a period of about 2 to about 8 hours relative to a milk replacer of pH 5.8 that lacks percarbonate. ### Claim 2 (depends on 1) The method of claim 1, wherein the percarbonate comprises sodium percarbonate. ### Claim 3 (depends on 1) The method of claim 1, wherein the livestock animals are calves. ### Claim 4 (depends on 1) The method of claim 1, wherein the percarbonate is present in the milk replacer at a concentration of about 4 lbs. per ton by dry weight of the milk replacer. ### Claim 5 (depends on 1) The method of claim 1, wherein the milk replacer comprises about 18 to about 30 wt % protein and about 15 to about 30 wt % fat by dry weight. ### Claim 6 (depends on 1) The method of claim 1, wherein the livestock animals are fed the milk replacer between birth and about 2 to about 12 weeks of age. ### Claim 7 (depends on 1) The method of claim 1, wherein in response to ingesting the milk replacer comprising percarbonate, the livestock animals increase a rate of weight gain relative to animals fed a milk replacer lacking percarbonate and/or having a pH of about 5.2. ### Claim 8 (depends on 1) The method of claim 1, wherein in response to ingesting the milk replacer comprising percarbonate, the livestock animals increase a rate of consumption of the milk replacer relative to animals fed a milk replacer lacking percarbonate and/or having a pH of about 5.2. ### Claim 9 (depends on 1) The method of claim 1, wherein in response to ingesting the milk replacer comprising percarbonate, the livestock animals increase a rate of consumption of a starter feed relative to animals fed a milk replacer lacking percarbonate and/or having a pH of about 5.2. ### Claim 10 (depends on 1) The method of claim 1, wherein the Salmonella comprises one or more strains of Salmonella selected from a group consisting of: S. Heidelberg, S. Dublin, S. Cerro, and S. Montevideo. ### Claim 11 (depends on 1) The method of claim 1, wherein the milk replacer comprises about 8 to about 31 wt % fat by dry weight. ### Claim 12 A milk replacer product comprising: an antibacterial system consisting of percarbonate and at least one acid selected from a group consisting of: citric acid, malic acid, valeric acid, acetic acid, propionic acid, butyric acid, formic acid, caproic acid, oxalic acid, lactic acid, benzoic acid, carbonic acid, phosphoric acid, hydrochloric acid, sulfuric acid, succinic acid, tartaric acid, fumaric acid, adipic acid, gluconic acid, pyrophosphoric acid and carbolic acid, wherein a concentration of percarbonate is effective to reduce bacterial growth within the milk replacer product; wherein the at least one acid reduces the pH of the milk replacer product to about 5.8, wherein the milk replacer product exhibits reduced growth of Salmonella over a period of about 2 to about 8 hours relative to a milk replacer product of pH 5.8 that lacks percarbonate. ### Claim 13 (depends on 12) The milk replacer product of claim 12, wherein the concentration of percarbonate is about 4 lbs. per ton by dry weight of the milk replacer.
