Effect of enterosorbents and vitamin C on food quality and environmental safety of broiler meat

Detoxification of salts of heavy metals at rational introduction of adsorbents in combination with a number of biologically active additives in the formulation of mixed fodders of meat poultry first of all with vitamins and antioxidants has been studied. At cultivation of broiler chickens in conditions of technogenic zone for increase of their meat productivity, nutritional value and ecological safety of meat in composition of mixed fodders of wheat-corn-rapeseed type with increased level of salts of heavy metals the adsorbent Evosorb in a dose of 1000 g/t and vitamin C in a dose of 500 g/t of feed should be jointly introduced. The research and production experiment was conducted in 2024 according to the generally accepted methodology. Four experimental groups of 100-day-old chickens of “Ross-308” cross in each group were formed for the research. Broilers of the 4th experimental group had the best slaughter performance, exceeding the control in terms of semieviscerated carcass weight by 10.29% (p < 0.05), eviscerated carcass weight by 10.35% (p < 0.05) and slaughter yield by 0.67% (p < 0.05). There was a significant (p < 0.05) increase in dry matter in the femoral and pectoral muscles of poultry by 1.08 and 1.12% and protein by 1.10 and 1.08% in broilers of the 4th experimental group against the control, accompanied by a decrease in fat by 0.54% (p < 0.05) and 0.55% (p < 0.05). Meat of broilers of the 4th experimental group was characterized by the highest biological value of protein, which surpassed the value of protein-quality index of pectoral muscle of the control by 15.48% (p < 0.05). Due to the joint feeding of the adsorbent and vitamin C compared to the control in the samples of the femoral and pectoral muscles of poultry the content of zinc was significantly (p < 0.05) lower by 3.06 and 3.46 times, lead by 3.12 and 3.18 times and cadmium by 3.07 and 3.18 times. There were no exceedances of the maximum permissible concentrations of these elements in the meat of broilers of the 4th experimental group in any case.
