The effect of substances isolated from an aqueous extract of oak bark on the concentration of chemical elements in the body of broiler chickens

Abstract

Relevance. A comprehensive study of the properties of plants containing phytobiotic components will make it possible to widely use plant extracts in animal feeding as biologically active additives of the latest generation based on raw materials of natural origin. The aim of the work is to study the effect of substances isolated from an aqueous extract of oak bark (BBVECD) on mineral metabolism in the body of broiler chickens.Methodology. The object of the study are broiler chickens of the Smena-8 cross. 120 heads of broiler chickens were selected for the experiment, which were divided into 4 groups by the method of analogues (n = 30). The control group received the basic ration (RR), I experimental — RR + BBVECD (1 ml/kg of live weight.), II experimental — RR + BBVECD (2 ml/kg of live weight.), III experimental — RR + BBVECD (3 ml/kg of live weight). The analysis of chemical elements in the obtained ash of the studied samples was carried out using the «Elan 9000» mass spectrometer and the «Optima 2000 V» atomic emission spectrometer.Results. The results obtained in the context of the effect of BBECD on mineral metabolism in broiler chickens should be discussed in the context of already available data that a number of compounds found in plant extracts may have the ability to chelate transition metal ions, especially Fe (II) and Cu (II), which is important. During the experiment, it was shown that the introduction of oak bark extract into the diet of broiler chickens mainly led to the accumulation of macronutrients (potassium — from 0.8 to 6.24%, magnesium — from 1.02 to 7.14%, phosphorus — from 5.31 to 7.9%) and essential trace elements in muscles (cobalt — 1.5 times, chromium — 3.67 times, lithium — 1.67 times, nickel — 4 times, silicon — 1.34 times), as well as to reduce the content of toxic and conditionally toxic elements in them: aluminum — 1.62 times, lead — 2 times. In this case, the most appropriate is the use of oak bark extract in a dose of 1 ml/kg of live weight of poultry.
