Dynamics of Some Mineral Elements Content in the Muscle, Bone and Liver of Quails Under the Apimin Influence

Abstract

In the system of full-fledged poultry feeding, particular importance is attached to providing them with mineral substances. The purpose of this study was to determine the effect of the Apimin mineral additive based on bee podmore on the content of zinc, copper, magnesium, and iron in the meat, liver, and bone tissue of quails. During the study, the following methods were used: zootechnical (to analyse the productivity of quails), physiological (to determine the digestibility of nutrients in the poultry diet), biochemical (to analyse the content of minerals in muscles, liver, and tubular bones), morphological (to determine the meat qualities of quails: mass of edible parts, meat carcasses), statistical (to determine the presence or absence of a substantial difference between the values). Justification of the effectiveness of feeding the Apimin additive was carried out based on a comprehensive study on the chemical composition of Apimin, retention of minerals, meat indicators, dynamics of zinc, copper, iron, magnesium content in muscle, bone, and liver tissues of quail. The research was conducted on Pharaoh meat quail from 1 to 56 days of age and quails from 60 to 120 days. Apimin contains calcium, magnesium, iron, zinc, manganese, phosphorus, silicon, and selenium. Feeding Apimin increases metabolism, the digestibility of copper was higher by 21.7%, zinc – by 5.9%, iron – by 8.9%, and magnesium – by 12.9%. Including the additive in the diet influenced increasing muscle mass, the ratio of pulp to bone was higher by 0.26. The content of zinc in pectoral muscles increased by 15.6%, in femoral and lower leg muscles by 2.6%, in the liver – by 5.3%; in pectoral muscles iron increased by 5.1%, in liver – by 13.1%. The copper content was 8.0% higher in the thigh and lower leg muscles, 3.2% higher in the liver, and 14.0% higher in the pectoral muscles. No effect of Apimin on magnesium content was found. With age, the content of ash in the bones of quail fed with Apimin decreased by 3.87%, the content of copper increased by 18.3%, and zinc by 27.6%.
