The experiment was conducted on 200 broiler chickens (Ross-308) with the purpose of evaluating the effect of the probiotic preparation “Entero-active” (containing lactic acid bacteria of the genus Lactobacillus and Enterococcus) on the mineral content of chicken muscles. The chickens were divided into 4 groups of 50 each. The control group used the main diet – complete feed. The experimental groups were fed with different doses of the probiotic feed additive for 42 days in addition to the main diet. It was established that supplementary feeding of broiler chickens with the probiotic “Entero-active” increases the retention of mineral elements of the feed. The use of the studied probiotic contributed to the increase of phosphorus content in the pectoral muscles by 4.7%, magnesium by 3.9% and iron by 46.5% compared with the control group. The mineral content in thigh muscles also increased: phosphorus by 4.7%, calcium by 4.1 times, iron by 70.5%, zinc by 5.4%, magnesium by 31.5% and copper by 4.2 times. Thus, the consumption of probiotic preparation by broiler chickens in various doses improves the mineral composition of carcass meat and contributes to obtaining safe food.
