Stress in farm animals is interpreted as a complex adaptive response of the body to unusual or extreme conditions caused by intense stimuli that can potentially disrupt its normal functioning. Among them, technological stresses, which are most common in modern pig breeding, are of particular importance. In such circumstances, the use of anti-stress drugs is considered as an effective tool for reducing their negative consequences.

The article presents the results of experimental studies aimed at scientific substantiation of effective approaches to reducing the effect of technological stress factors on the clinical and physiological state of young pigs by using a new anti-stress drug, in comparison with traditional means. Based on laboratory data, it was established that the introduction of the experimental drug from the very beginning of the development of the stress reaction activates hematopoietic processes in the body of young animals of Group III, causing an increase in the blood content of red blood cells by 8.4% (p<0.05) and 3.5%, white blood cells-by 3.4 and 0.9%, hemoglobin concentrations – by 5.7 and 4.3% and Total Protein – by 10.5% (p<0.001) and 5.2% (p<0.001), compared with analogues control and II experimental groups, maintaining the general trend of increasing these indicators at the end of the fattening period. In addition, the results of the studies clearly demonstrate the positive effect of the applied anti-stress drugs on the functional state of young pigs, while the studied indicators remained within the physiological norm, regardless of the group. At the initial stage of the experiment, piglets of Group I showed a slight increase in the respiratory rate, compared with peers of groups II and III by 0.4 and 0.8 movements/min or 1.1 and 2.2%, acceleration of the heart rate by 2.8 and 4.2 beats/min or 2.6 and 3.9% against the background of stable body temperature parameters, the difference in which was respectively 0.24 and 0.30 ^оС or 0.6 and 0.8% greater in young animals of the control group. At the final stage of the study, a similar dynamics of changes in clinical and physiological parameters was noted.
