Effect of probiotics on the chemical, mineral, and amino acid composition of broiler chicken meat

Ju. N. Podolian


The experiment was conducted to examine the influence of probiotic preparation on the mineral contamination of the broiler chicken muscles. Investigational product contains probiotic lactic acid bacteria of genus Lactobacillus and Enterococcus. It is proved that additional feeding of probiotic “Entero-active” to broiler chickens increases retention of mineral elements of the fodder. To study the effect of probiotic on chicken meat the contamination of minerals in the experimental poultry meat was researched. The studies proved that the additional use of the studied probiotic supplements with food of broiler chickens allowed increasing phosphorus contamination by 4.7%, magnesium by 3.9% and iron by 46.5% in the pectoral muscles compared with the control group. The use of probiotic for broilers feeding has increased phosphorus by 4.7%, calcium by 4.1 times, iron by 70.5%, zinc by 5.4%, magnesium by 31.5% and copper in 4.2 times in thigh muscles of poultry. Thus, consumption of probiotic preparation by broilers in various doses improves the mineral compound of meat carcasses this meat is also considered as free range food. It was proved that probiotic increases the synthesis of such essential amino acids in the pectoral muscles as lysine by 1.66%, histidine by 0.03%, arginine by 0.38%, threonine by 0.07%, valine by 0.16%, methionine by 0.33%, leucine by 0.1% and phenylalanine by 0.17%. The increasing of level of lysine and histidine respectively by 0.05 and 0.08% is observed in the thigh muscles of broilers under the influence of probiotic. We have proved that the optimal dose for broiler chickens is 0.25% for the age of 1-10 days, 0.1% for the age of 11-28 days, 0.05 % for the age of 29-42 days, the percentage is for broiler chickens feed weight.
