The influence of polyphenol extract from nettle (Urtica dioica) on the zinc concentration in the blood serum of roosters

Abstract

Zinc, being a trace element necessary for vital activity, is indispensable for the survival of living organisms. This element is of major importance in animal nutrition, but it also contributes to the metabolic activity of over 200 enzymes of living organisms, cell division and synthesis of DNA, proteins, tissue growth and development, immune system functioning, bone mineralization, blood coagulation, carrying out spermatogenesis, etc. Through its biological properties, it stimulates digestion, assimilation and has an important role in the activity of the reproductive organs and the metabolism of the digestive tract. It is found that zinc can exert a protective effect against testicular damage and plays an essential role in maintaining reproductive functions. Feed is the main source of zinc for animals, only a small part can be obtained from drinking water. Foods differ in their content of zinc. The daily ration is dependent on gender, age and the general state of the body`s health. Based on these considerations, this study was dedicated to the research of the quantitative changes of this element under the influence of polyphenols from nettle.
