The measurement of the surface tension (ST) parameters of the major animal fluids (blood, urea, milk, etc.) is one of the promising methods for monitoring of animal’s physiological-biochemical status (APBS). Our group is working over 20 years on APBS fundamental and applied aspects. The aim of this work was to obtained equilibrium surface tension (eST) and extrapolated tilt angle (eTA) of the blood serum of hybrid pigs using PAT-device (“Sinterface Technologies”, Germany). The PAT-device is using “hanging drop” method. The average eST and eTA data of the blood serum at initial (final) point of hybrid pig’s fattening were the following: mean 44.04±0.16 (43.58±0.23) mN/m and 13.16±1.16 (14.40±1.46) mN•m-1•s-½; Standard deviations (SD) 0.88 (0.84) mN/m and 6.33 (5.28) mN•m-1•s-½, respectively. The SD values had the following meaning: the low standard deviation in the case of eST indicated that the values tend to be close to the average eST data (“expected values”) of the set, While a high standard deviation in the case of eTA indicated that these values are spreading out over a wider range. It is important to highlight that moderate correlations were found between the eST (eTA) parameters and the studied biochemical parameters: total amount of proteins, albumins, globulins, The ratio of albumins to globulins, Total phospholipids, Activity of aspartate aminotransferase, Activity of alanine aminotransferase, De Ritis coefficient, Total cations and Total anions. The authors recommended to use the eST and eTA data in the range of 42-46 mN/m and 10-30 mN•m-1•s-½, Respectively, As reference for the blood serum evaluation APBS at initial (final) point of hybrid pig’s fattening.
