The aim of our study is to examine the influence of administration of 3-isobutyl-l-methyl-xanthine (IBMX), inhibitor of cAMP and cGMP phosphodiesterases on ovarian functions (folliculogenesis, atresia and luteogenesis), as well as on some reproductiv

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
