Correction of protein metabolism in cows using nanoaquachelates taking into account vegetative regulation

Improvement of protein metabolism in cows will contribute to better body weight gain and ensure sustainable milk production. The experimental groups of cows were formed by means of a variational pulse oscillometric study, which resulted in the formation of three groups: normotonic, vagotonic, sympathotonic, each of which was divided into 2 groups: control and experimental. The experimental group during lactation for 30 days is fed a nanopreparation of trace elements Mg, Zn, Ge and Fe, in a dose of 10 ml per day with the content (mg/day): Mg – 50 mg/day, Zn – 50 mg/day, Ge – 10 μg/day and Fe – 20 mg/day, the results were evaluated by biochemical blood test. In the experimental group of normotonics, the content of total protein was 6.78 % lower than in the control group (P < 0.01), but the content of albumin was 14.56 % higher than in the control group (P < 0.001). In the group of vagotonics, total protein did not change significantly between control and study, but the albumin content increased by 17 % in the study group compared to the control group (P < 0.01). In sympathotonics in the blood of cows of the experimental group, an increase in the level of total protein by 3 % was found, which was provided by albumin, which was 16 % higher in the experimental group of cows (P < 0.01), while the control group was characterized by a higher content of globulins by 7 % (P < 0.01). It was found that due to the increased metabolism of structural proteins in the experimental group of animals, the level of glucose in the blood of cows decreased by 26 % (P < 0.001), vagotonics by 21 % (P < 0.05) and sympathotonics by 11 % (P < 0.05), respectively, compared to the control groups that did not receive food additives. It has been established that, depending on the tone of the autonomic nervous system, the increase in protein metabolism in cows has different efficacy. The prospect of further research is the use of nanoaquahelates with adjusted doses in accordance with the individual characteristics of animals and the evaluation of further efficacy.
