  • Patent number: 4421858
    Abstract: The present invention describes a method where, by using gentian violet as a tracer substance, the concentration of one or more selected components or factors of a complete animal feedstuff may be monitored throughout the life of the feed whether at the mill, in transit or at the place of its end use. In one embodiment, the method may be used to determine quickly whether any separation of components has occurred thereby destroying the homogeneity of the feedstuff and potentially endangering the animals to which the feedstuff is provided.
