Nineteen acid-soluble (free) nucleotides, two mononucleotides and one unidentified nucleotide in the kidneys of calves from the Black-and-White and Bulgarian Brown cattle breeds were found by the two-way paper chromatography method. The quantity of triphosphate nucleotides was significantly higher (P0.001) in comparison with that of di- and monophosphate nucleotides in both studied breeds. The total quantity of adenosine and guanodine nucleotides was significantly higher (P0.001) in the kidneys of the calves from the Bulgarian Brown breed in comparison with that of the calves from the Black-and-White breed. It was obtained that the quantity of uridine triphosphate nucleotides was significantly (P0.001) higher in comparison with the quantity of di- and monophosphate nucleotides in both examined breeds. The quantity of NAD was significantly (P0.001) higher in comparison with the quantity of NADP in both examined breeds.
