Abstract

The metabolic profile test (Payne) characterises from the investigation of the blood of the 3-5% of animals, whether the nutrition of the whole herd Is sufficiant. In it the most important metabolic parameters are investigated (proteins, macroelements, blood plasma glucose and some other basic blood parameters). The aim was to determine the possibility of addition of the glycated protein parameters (glycated hemoglobin, GHb and serum/plasma fructosamine, SeFa) to the above mentioned ones. Blood samples of high yielding Holstein Friesian cows (n=32) were examined from two weeks before till six weeks after calving, in every two weeks (Table). Focusing on the parameters of the carbohydrate metabolism the basic values of GHb, SeFa, and blood plasma glucose and their changes in the critical state of the reproductional biology were described (Figure 1.). A close, significant retrospective correlation was found between GHb and the 4 weeks earlier, and between SeFa and the two weeks earlier measured blood plasma glucose concentration (r=0.95 and 0.97, respectively) (Figure 2.). Thus, beside of the actual blood glucose level which is determined from the blood sample on the same day, SeFa and GHb determined at the same tune give about the carbohydrate metabolism and energy supply for the previous 2 weeks and for the earlier 4 weeks, respectively a more accurate and more realistic information, than the concentration of the blood plasma glucose. (The latter one changes after the neurohormonal changes at every time). So, the suitable change of feeding regime can be done in time for the prevention of possible metabolic disorders (e.g. ketosis). It might be especially important in the case of the highly valuable, high yielding dairy cows (and similarly in some other species) to think about the possibility of adding the glycated parameters to the metabolic profile test.
