Influence of copper nanopowder on parameters of carbohydrate and lipid metabolism of Holstein heifers

The paper presents the results of the analysis of the usefulness of the mineral composition of diets and the effectiveness of the use of mineral and vitamin supplements in feeding cows of different technological groups. The analysis showed that the amount of calcium and phosphorus in the diets was close to the norm. Extremely high concentrations of elements such as magnesium, potassium and sodium were noted with an obvious lack of chlorine and sulfur. The cation-anion balance was positive: the range of indicators ranged from 14.98 to 23.49 and a tendency to increase this indicator by the end of lactation was revealed. The ratio of calcium and phosphorus, as well as potassium and sodium did not exceed the established norms. For most of the trace elements, the excess of the recommended norms was determined, which can be justified due to the low digestibility of trace elements in the body of cows.

“…For animals from the age of 1 month, an aqueous suspension of a dietary copper nanoparticles supplement in a dose of 0.04 mg/kg was orally administered on daily basis by considering the live weight. The suspension was administered during the second, fourth, sixth, ninth, and eleventh month of age, due to the high chemical activity of the nanoparticles and prolonged action, confirmed by previous studies (Polischuk et al, 2015b;Makarov et al, 2017;Nazarova et al, 2019). The weight of the control and treatment groups was measured in kg every month (Graph 1).…”

The current study aimed to investigate the effect of copper nanopowder on physiological and mineral metabolism indicators of Holstein cattle during the growth process of the animal. There were two experimental groups (control and treatment) and each one included seven Holstein heifers. From the first month of each heifer in the experimental group, a suspension of copper nanoparticles in a dose of 0.04 mg/kg was orally administered daily to the usual diet. The biologically active additive was administered to the animal’s diet at intervals. The weight of the animals was measured monthly, a clinical blood test was performed, the mineral composition of the blood was studied, the mineral composition of animal hair was also examined. The findings indicated a positive dynamics in the increase of body weight in the treatment group, compared to the control group. As a result of clinical blood tests, it was noted that the number of erythrocytes, the level of hemoglobin, and hematocrit increased in the experimental animals due to copper nanoparticles compared to these parameters in these animals at the beginning of the tests. Mineral analysis of blood samples in the treatment group presented an increase in the levels of copper, potassium, iron, zinc, and manganese while in animals of the control groups there was an increase in sodium, calcium, and phosphorus. According to the blood serum and hair analysis, copper in the nanodispersed state indicated antagonistic effects on boron, silicon, antimony, molybdenum of the treatment group and there was a synergist in aluminum, titanium, manganese, cobalt, iron, and potassium levels compared to the beginning of the experiment. The obtained results indicated that the addition of copper nanopowder to the diet of experimental animals increased the growth, stimulated the function of hematopoiesis, and improved the characteristics of mineral metabolism of the Holstein heifers.

“…Recent developments in the field of physiology of horse breeding have led to intensification of biotechnological and neuroimmunoendocrine studies [1][2][3][4]. The use of nanotechnology, in particular, ultrafine metal polymer compositions, is of great interest, but their effect on the animal organism has not been fully studied [5][6][7][8].…”

The paper presents the results of studies of the physiological state of stallions and their reproductive function in respect of the season, and according to blood samples the mechanisms of their physiological processes are adjusted using the ultrafine metal-polymer composition “iron-copper-zinc”. According to such biochemical blood parameters of stallions as total protein and its fractions: lactate dehydrogenase (LDH), alkaline phosphatase (ALP) and α-amylase, significant differences in the seasonal aspect were revealed. A number of features of blood morphology in connection with the season were noted. These were an increase in the concentration of erythrocytes, leucocytes, hemoglobin, eosinophils and lymphocytes in spring. An increase in the concentration of testosterone, the main populations of lymphocytes and subpopulations of T cells in the blood of stallions in the spring-summer period was established. The positive effect of the composition of nanosized metals on metabolic and enzymatic processes was revealed.
