Abstract

One of the current challenges in the meat industry is the efficient use of protein raw materials and the development of rational ways to utilize meat from spent laying hens in order to compensate for the shortage of raw meat resources in processing industries. The aim of this study was to determine the mineral composition of chicken meat and to comparatively evaluate the levels of macro- and microelements in the meat of broiler chickens and spent laying hens. In this study, the mineral composition of the drumstick, breast, and thigh muscles of chickens withdrawn from egg production at Saryagash Kus LLP was analyzed. Carcasses of broiler chickens from Aleel-Agro JSC were used as control samples. The analysis was performed using inductively coupled plasma mass spectrometry (ICP-MS) with a Varian-820MS instrument in accordance with ST RK ISO 17294-2-2006. The results showed that chicken meat contains macroelements such as sodium, magnesium, phosphorus, potassium, and calcium, as well as microelements including aluminum, zinc, and silicon. In the drumstick meat of spent laying hens, the content (wt. %) was: Na – 7.16; Mg – 2.85; K – 25.96; in breast meat – Na – 5.35; Ca – 1.24; and in thigh meat P – 17.42; K – 28.71; Mg – 2.55. These values were higher compared with those found in broiler chicken meat. Overall, the differences in the content of major macro- and microelements between the two types of chicken meat were relatively small.
