  • Patent number: 6406726
    Abstract: For preparing cattle feed mixtures, especially pumpable liquid feed mixtures, the feed components are added consecutively to a weighing and mixing container and mixed. Before or while the feed mixture is being prepared, the pH of the mixture is measured and, if it exceeds a specified value during a continued mixing process, acid is added as the last additive to the feed mixture until the specified value is reached. For this purpose, a pH measuring probe, which is passed through the wall of the container, is provided in the lower region of the weighing and mixing container.
