<abstract xmlns="http://www.w3.org/1999/xhtml"><p> The aim of this study was to demonstrate the histochemical and histopathological alterations in the livers of cows with a tendency to become emaciated (body condition score - BCS1 and 2) and a tendency to become fattened (BCS4 and 5) in comparison to the cows of average body condition (BCS3) presented as a control. The histochemical analysis (PAS reaction) showed that the influence of emaciation and fattening in our study was manifested by a decreased occurrence of glycogen and a decreased level of the PAS-positive matter in the hepatocytes of dairy cows with BCS1, 2, 4 and 5. An abundant accumulation of lipids in the form of large lipid droplets, liposomes and lipoproteins observed in the hepatocytes of emaciated and fattened (BCS1 and 5) cows may be related to moderate-severe steatosis.
