An application of biochemical methods and surface tension measurements of cow blood in the laboratory diagnostics
Blood tests allow an objective assessment of the state of animal health and the timely identification of changes occurring in the body. Measurement of dynamic surface tension (DST) serum is a modern analytical method for the preliminary assessment of its biochemical composition. In is known that feeding one of the factors determining the state of health of the animal. To assess the effect of diet at the transition to the winter diet the two animal groups of 10 cows were formed. Animals of the experimental group received a diet typical of the winter period (“silage and the concentrate” nutrients), whereas the control group - typical for the summer period. The diet was balanced by nutrients and energy. The influence of winter diet on such metabolic parameter as cholesterol, triglycerides, total protein and albumin fraction. The paper assessed the reliability of the application of the method of dynamic surface tension measuring of blood in a comprehensive assessment of the impact of diet on the physiological-biochemical status of lactating cows.
