Eighteen acid-souble (free) nucleotides in the liver of calves from the Black-and-White and Bulgarian Brown cattle breeds were found by the two-way paper chromatography method. The quantity of adenosine- and guanodine-diphoshate nucleotides was significantly higher (P0.05) in comparison with that of tri- and monophosphate nucleotides in both examined breeds. The total quantity of adenosine and guanodine nucleotides was significantly higher (P0.001) in the liver 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 nucleotide was significantly (P0.05) higher in comprison with the quantity of diphosphate and monophoshate nucleotides in the liver of the calves in both examined breeds. The total quantity of uridine nucleotides was significantly higher (P0.001) in the liver of the calves from the Bulgarian Brown breed in comparison with that of the calves from the Black-and-White breed. It was found that the quantity of the uridine diphosphate sugars was significantly higher (P0.001) in the liver of the calves from the Bulgarian Brown breed in comparison with that of the calves from the Black-and-White breed. It was found that the quantity of the NAD was significantly higher (P0.001, P0.01), in comparison with that of the NADP in the liver of the calves in both studied breeds. The quantity of NAD and NADP was significantly higher (P0.01, P0.001) in the liver of the calves from the Bulgarian Brown breed in comparison with that of the calves from the Black-and-White breed.
