The influence of biologically active additives of natural origin on mineral composition of edible body parts of broiler chickens

Abstract

The studies were carried out on broiler chickens of the Arbor Acres cross. The content of nutrients and trace elements in the basic diet of the examined birds was within the requirements of broiler chickens during the corresponding growing periods. Experimental scheme: control group - basic diet (BD); I experiemental group (BD + quercetin at a dosage of 10 mg/kg f.w./day); II experimental group (BD + quercetin (2.5 mg/kg b.m./day) + 7-hydroxycoumarin (0.1 mg/kg b.w./day)); III experimental groip (BD + 7-hydroxycoumarin (0.3 mg/kg f.m./day) + vanillin (0.3 mg/kg f.m./day)); IV experimental (BD + vanillin (0.5 mg/kg body weight/day)). It was established that the introduction of the studied plant additives into the diet of the experimental bird was accompanied by a decrease in the concentrations of Ca, Na, Co, Mn, Se, Al, As, Hg, Pb, Sr in the pectoral muscles. The addition of 7-hydroxycoumarin in combination with vanillin to the basic diet of broiler chickens was accompanied by an increase in sodium concentration by 19.5% (PЈ0.05), while the inclusion of the quercetin + 7-hydroxycoumarin complex increased the level of selenium in the thigh muscles by 108% (PЈ0.001). At the same time, vanillin was characterized by the greatest influence on the elemental composition of the femoral muscle. The established trend of an increase in the concentration of lead in liver together with a decrease in the content of lead in the pectoral muscles, indicates an increase in the intensity of the detoxification process of the body. It makes it possible to recommend using quercetin supplements to reduce the level of lead in the meat of broiler chickens.
