The metabolic profile of Simmental service bulls

The levels of biochemical parameters in the blood serum of Simmental service bulls were studied.The research was conducted on twelve bulls at the age of four to seven. The blood was taken on four occasions by needle biopsy from the vena Jugularis externa. In the samples of blood serum, the activities were specified of alanina aminotransferase (ALT), aspartate aminotransferase (AST), gamma glutamyl transferase (GGT), creatine-kinase (CK) and concentrations of the total proteins, albumins, calcium and magnesium, triglycerides and cholesterol. Since there are no data concerning bulls, the results obtained were comapred with data from literature on cows. The levels of total proteins, albumins, GGT and CK in the serum of examined bulls are higher than in cows, while the levels of AST and magnesium are lower. The levels of tryglicerides, cholesterol and calcium are almost equivalent. The differences observed indicate the necessity of establishing referential rates for biochemical parameters in bulls as opposed to cows. The results obtained will be useful in routine diagnostics as the metabolic profile of Simmental bulls.
