Sažetak
During the production cycle, especially under high production, continual monitoring of dairy cow health is essential in order to recognize animals that are at the edge of their adaptation abilities and to remedy any potential problems as soon as possible. The metabolic profile test is a useful tool to this aim. This study analysed indicators of energy status, protein status, mineral status and liver enzyme activity in the serum of 34 Holstein dairy cows from two farms. Samples were taken from three groups of cows in different phases of production. The first group consisted of cows lactating less than 45 days (N=6 from each farm). The second group included cows lactating more than 75 days (N=5 from each farm), and the third group consisted of cows in the dry period (N=6 from each farm). The following parameters were determined in blood samples: concentrations of glucose, triacylglycerols, cholesterol, total proteins, albumin, urea, beta-hydroxybutyrate (BHB), free fatty acid (FFA), calcium, magnesium and phosphorus, and activities of gamma-glutamyl
transferase (GGT), aspartate aminotransferase (AST) and alkaline phosphatase (AP). The glucose concentration in all three groups of cows at farm I was lower than the reference values specified in the literature. Average values of cholesterol concentration, FFA and BHB in all cows were higher than the reference levels set for these indicators, while the values of triacylglycerol, total protein, albumins, globulin, urea, calcium, magnesium and phosphorus, and activities of GGT, AST and AP were within the reference intervals. The results of this study indicate a negative energy balance, manifested as hypoglycaemia and hypercholesterolemia and by increased concentrations of FFA and BHB. Accordingly, feeding on the farm was corrected with glucose precursors added to meals, which has led to improvements in productivity and animal health.
