[Microbiological evaluation of milk feed mixtures for calves]

Hundred-and-two samples of four kinds of mild replacers for calves, produced in Czechoslovakia, were examined and evaluated. None of the studied pathogenic germs was detected in the samples. More than a half of the samples contained 1000 and 10000 mesophilous germs per 1 g. More than a third contained 1 to 1000 coliform germs per 1 g. On the basis of the results it is recommended--within microbiological requirements for the product--to propose that the maximum total number of microorganisms should be 100000 per 1 g of product.
