The indexes of mineral exchange in laying hens under the influence of Selenium and Zinc nonoacquahelates and vitamin E

Abstract

The article presents the results of the study of the influence of nanoacquahelats of biogenic and biocidal metals Selenium and Zinc together with vitamin E, on the mineral metabolism indexes of hens of Loman Brown breed. It is known that the inflow of mineral elements such as Calcium and inorganic Phosphorus into the body and its proper usage is essential for the maintenance of egg productivity and egg quality. In this regard, it is promising to study the changes of the above-mentioned processes with the Selenium, Zinc and vitamin E nanoacqualates supplementation. It has been established that the feeding of Selenium and Zinc nanocarboxylic acids with vitamin E positively affects the exchange of Calcium and inorganic Phosphorus in the laying hens. In particular, the content of calcium in the serum of tested hens was significantly higher (17.3-26.7%), on the 60th and 90th days of the experiment, comparing with the control group. The level of inorganic phosphorus, on the 60th and 90th days of the experiment, also increased by 17.7% and 16.9%, respectively, in experimental group of layer hens compared to control one. It is known that macroelements Ca and inorganic Phosphorus are important components for the organism of animals and, especially, birds. These minerals have no nutritional value, are not used by the body as a source of energy, but their role as structural elements cannot be overestimated. Both Calcium and inorganic Phosphorus are part of almost all organs and tissues. The growth and development of the organism, as well as its productivity depends on the presence of these elements in the diet. In addition, Calcium and inorganic Phosphorus are actively involved in the regulation of a number of vital functions. In the birds, it is the synthesis of proteins and the intense formation of egg minerals. They are also necessary for the further formation of bone tissue of the embryo. Consequently, the presence of these minerals in the diet and in the body of layers hens, to a large extent determine their weight and quality of eggs. The obtained results show the use of nanoacquahelats of Selenium and Zinc together with vitamin E stimulate phosphorus-calcium metabolism and alkaline phosphatase activity due to their biophysical properties which are based on activation of many biochemical processes according to the effect of Borisevich-Kaplunenko-Kosinov. Key words: Calcium, Phosphorus, laying hens, Selenium, Zinc, vitamin E.
