Influence of lipid levels in the diet on the degree of absorption of minerals in the body of broiler chickens

Abstract

Relevance. Precocious modern crosses of broiler chickens need a high-energy diet. Vegetable oils, being a concentrated source of energy, cover the necessary energy demand. At the same time, the amount and type of fat used in the diet to increase energy value can affect the metabolism of trace elements. Thus, there may be a relationship between the concentration and type of lipids in the diet and the metabolism of trace elements.The purpose of the study was to evaluate the effect of various doses of sunflower oil in the diet on minerals in the body of broiler chickens.Methods. Experimental studies to assess the effect of a high-energy diet on the mineral status of the body were conducted in three groups of broiler chickens of the Arbor Acres cross, formed by the method of pairs of analogues (n = 35). The basic diet was adjusted for metabolic energy. The subject of research is the mineral composition of the liver and bone tissue, as well as biochemical and morphological parameters of blood.Results. Based on research, it has been established that feeding broiler chickens is highly co-energy diet causes changes in the metabolism of certain trace elements and leads to to malabsorption. In the liver, blood serum and bone tissue, the studied elements (Fe, Cu and Zn) decreased in the experiment. The result obtained requires further research and indicates on the possible need for correction of mineral nutrition in high-energy diets.
