Investigations refer to the influence of fodder containing soil dust as one of the ingredients on morphology of the liver and the weight of experimental animals. Fodder containing soil dust was given to animals for various periods of time, the longest was 18 weeks. The results indicate that the intensity of morphological changes in the liver depends on the time of giving fodder. The observed changes referred to the vacuolization of hepatocytes, increase in the number of stellate cells Browicz-Kupffer, and apart from that lymphocytic infiltrations occurred locally. The weight of the experimental animals in the initial period (up to 3 weeks) decreased and then came back to normal in the later period, but in some animals it even decreased.
