The article presents data on the influence of the basic characteristics of cortical processes and the type of autonomic regulation of cardiac rhythm on indicators of lipid metabolism in sows’ blood. In experiment dry sows of a large white breed of 3 years old were used. Depending on the type of higher nervous activity, 4 experimental groups of sows were formed: strong balanced mobile, strong balanced inert, strong unbalanced and weak types. Depending on the type of autonomic regulation of cardiac rhythm, 3 experimental groups of sows were formed: normotonic, vagotonic and sympathicotonic. Cholesterol and triacylglycerol content were determined in serum, and the data were processed using correlation methods and analysis of variance. The results of studies have shown that there are no significant differences by the cholesterol and triacylglycerol content of sows' blood depending on the type of autonomic regulation of cardiac rhythm. It has been established that sows with weak and strong types of higher nervous activity are significantly different by serum triacylglycerols and cholesterol levels. According to the correlation analysis, significant relationships were found between strength (r=0.77; p<0.01), balance (r=0.47; p<0.05) and mobility (r=0.55; p<0.05) of cortical processes and triacylglycerols content in blood, as well as the strength and balance of cortical processes (r=0.56-0.59; p<0.01) and cholesterol content in blood. Under these conditions, the degree of influence of indicators of conditioned reflex activity on triacylglycerols and cholesterol content in blood was η2 x=0.31–0.41 for р<0.05. Thus, the typological features of higher nervous activity have a significant effect on indicators of lipid metabolism in sows’ blood, whereas the degree of influence of the type of autonomic regulation of cardiac rhythm is negligible
