Features of Carbohydrate-Lipid Metabolism in Dogs With Different Types of Higher Nervous Activity

Abstract

The relevance of the study is due to the lack of data on the cortical mechanisms of regulation of carbohydrate and lipid metabolism in the body of dogs. In this regard, this article is aimed at revealing the issue of lipid and carbohydrate metabolism in dogs with various types of higher nervous activity under the influence of short-term food deprivation. It is shown that the effect of short-term food deprivation is characterized by changes in metabolism in the body of dogs, which are limited by the state of the nervous system of these animals. In the intact state, the glucose content in the blood of dogs with different types of higher nervous activity does not reliably differ, while the lactate content in the blood of dogs with a weak type of higher nervous activity is higher by 16.2% (P < 0.01), and pyruvate is lower by 6.3% (P < 0.001) from the indicators of dogs with a strong balanced mobile type. Within a day after the beginning of food deprivation, the glucose content in the blood of dogs decreases by 4.6–8.2% depending on the type of nervous activity (P < 0.05–0.01). During the day after the beginning of deprivation, the ratio of lactate to pyruvate in the blood of dogs, depending on the type of higher nervous activity, increases by 19.1–36.0% (Р < 0.01), the content of total cholesterol and triacylglycerols in the blood plasma decreases by 3, 5–12.9% and the ratio of lipids of different densities changes significantly. In particular, in the blood plasma of dogs of a strong balanced mobile type of higher nervous activity, the cholesterol content of high-density lipoproteins decreased during the day by 7.1% (Р < 0.05). Thanks to the conducted research, it was possible to obtain fundamental knowledge of the cortical mechanisms of regulation of carbohydrates and lipids in the body of dogs, which will form the basis of the development of new, modern methods of correction of metabolism, taking into account the type of higher nervous activity. Prospects for further research consist in the development of new methods of correction of metabolism based on the use of nanoaquachelates of biogenic metals, taking into account the individual characteristics of the body of dogs.
