THE CONTENT OF SATURATED FATTY ACIDS IN THE BLOOD PLASMA OF GOATS DEPENDING ON THE TONE OF THE AUTONOMIC NERVOUS SYSTEM

Abstract

Currently, goat breeding is actively moving to one of the first positions in the market of dairy and meat products. People are increasingly consuming goat's milk rather than cow's milk. Scientists are currently actively studying the factors affecting the content of fatty acids in the body of goats and in the milk they produce. Individual characteristics of each organism can be characterized as one of the most significant factors. The autonomic nervous system is one of the components of a number of systems in the adjustment of animal homeostasis. The purpose of the study is to establish the influence of the tone of the autonomic nervous system on the content of saturated fatty acids in the blood plasma of goats. Research was conducted on the basis of a private dairy farm in the village of Knyagininok, Lutsk district, Volyn region, goat breed – Zaanenskaya. Physiologically healthy 50 goats of 2-3 lactations were selected for variation-pulsometric research. The types of autonomous regulation were determined by determining the state of the cardiovascular system according to Baevsky. The content of saturated fatty acids in blood plasma lipids was determined by the method of gas chromatography with the study of the following fatty acids: butyric, caproic, caprylic, capric, lauric, myristic, pentadecanoic, palmitic, margaric, stearic, arachinic, tricosanoic acid. By comparing the obtained results, differences in the content of saturated fatty acids in blood plasma lipids of goats were established. It was established that the tone of the autonomic nervous system has an effect on the content of saturated fatty acids in the blood plasma of goats. It was determined that animals with a preference for the sympathetic nervous system have a lower content of saturated fatty acids (capric, myristic, pentadecanoic, palmitic, stearic, tricosanoic) in relation to other research groups (Р<0.05, Р<0.001). The experimental group of vagotonics has the highest content of saturated fatty acids (capric, myristic, pentadecanoic, palmitic, stearic, tricosanoic) in the blood plasma of goats (Р<0.05, Р<0.01, Р<0.001). The experimental group of normotonics occupied an intermediate place in terms of the content of saturated fatty acids in the lipids of the blood plasma of cows.
