The effect of gamma-octalactone supplementation on the content of chemical elements in the muscles and liver of broiler chickens

Relevance. In recent years, a large number of new herbal preparations have appeared on the market, including gamma-octalactone. It is a naturally occurring compound isolated from Eucalyptus viminalis leaf extract. This compound has a wide range of therapeutic properties, which is associated with its antiinflammatory, antiseptic effect, stimulates appetite, increases the secretion of digestive enzymes and increases performance in animals.

Materials and methods. The paper studied the features of the accumulation of chemical elements in the body tissues of broiler chickens when the compound gamma-octalactone was included in the diet. The studies were carried out on broiler chickens of the Arbor Acres cross at the age of 7–42 days. According to the scheme of the experiment, inthe diet of chickens of the 1st, 2nd and 3rd experimental groups was added gamma-octalactone at a dosages of 0.05, 0.1 and 0.2 ml/kg of b.w./day. The elemental composition of biosubstrates was studied using atomic emission and mass spectrometry.

Results. It was found that the addition of gamma-octalactone contributed to the redistribution of chemical elements in the body tissues of the experimental poultry. In particular, the broilers of the experimental group that received gamma-octalactone at a dosage of 0.05 ml/kg of b.w./day had higher concentrations of B, Co, Ni, Se, V, Zn in the pectoral muscles. An analysis of the concentrations of the main essential elements in the thigh muscles of broiler chickens showed that feeding gamma-octalactone at a dosage of 0.05 ml/kg of b.w./day was accompanied by a significant increase in the content of Ca, Na, Fe, Si and Zn and a decrease in the levels of Cr, Cu and Ni relative to poultry of the control group. There was also a significant increase in the concentrations of Cu, Fe, Se, Zn, Mg, P in the liver of chickens of the experimental group, who received gamma-octalactone in the diet at a dosage of 0.1 ml/kg of l.w./day, against the background of a decrease in the concentrations of Si and Na.
