Abstract: The invention relates to a method of increasing the protein contents of milk in milk producing animals by introducing into the animal a culture of one or more non-pathogenic lactic acid producing live bacteria in admixture with a carrier. The invention also relates to a preparation containing said lactic acid producing bacteria in admixture with a carrier facilitating the optimal growth of the bacteria in the stomach-intestine system of the animal. The invention also deals with the use of non-pathogenic lactic acid producing live bacterial for increasing the protein contents of milk in milk producing animals.

Abstract: A process for supply of low concentrations of biologically active materials to base materials such as a processed foodstuff or an animal food, in which the biologically active material is slurried in an inert carrier, where it is insoluble, to form a homogeneous suspension, after which the suspension is applied to the base material by means of a device converting the suspension to an easily applicable form, the suspension coating the surface of the base material in an even layer. The suspension is maintained homogeneous by stirring and at an even temperature before being applied to the base material at such a rate than an even and predetermined concentration of the biologically active material is obtained per weight unit distributed on the surface of the base material.

Abstract: Green fodder is fermented with a lactic acid producing Streptococcus faecium producing a metabiolite having anti E-coli activity.

Abstract: A method for cultivating fast growing bacteria and their stable metabolites in order to reach optimal cultivating time is disclosed which comprises introducing a volume of inoculum containing the bacterium sought to be cultivated and a quantity of nutriment containing a nitrogen source, growing factors, a carbon source, and a pH-stabilizer into a fermentor. The volume of inoculum in the fermentor is utilized as a production determinative factor and is determined according to the following equation:a = V.multidot.n/2.sup.twherea = volume of inoculum in litersV = cultivating medium's total volume in litersn = bacterium strain's generation time in hourst = cultivating time in hours.The result is that a grown cultivating medium is obtained which includes a mass of the desired bacterium.
