BOBYLEVAsAbstract The aim of the study is to assess the meat productivity and the specific features of metabolism inthe broiler chickens, raised in the industrial zone and fed with the diets, supplemented with theadsorbents (sugar beet pectin and ProSid TB 102) to provide the heavy metal detoxication. The experiments were conducted on the broiler chickens of the Smena-7 crossing. Four groups ofmatched day-old chickens were formed. The heavy metal content in the samples of forage, blood,and meat was measured with the atomic absorption analysis. The joint supplementation ofthe rations, containing increased amounts of heavy metals, with ProSid TB 102 (2000 g/ton offorage) and sugar beet pectin (2% of the forage weight) had the most pronounced beneficial impacton the economic and biological parameters of the chickens. The highest survival rates and liveweight gain in the birds of the 3rd experimental group were caused by the joint supplementationwith the chosen compounds. We observed positive effects of the examined substances on themorphological and biochemical parameters of blood. The birds of the 3rd experimental groupshowed 2.92-fold decrease in the lead content, 1.89-fold decrease in the cadmium content, and 2.03-fold decrease in the zinc content in blood. We detected an improvement in the sanitary andhygienic parameters of the poultry meat, 3.1-fold decrease in the lead content, 2.0-fold decrease inthe cadmium content, and 2.1-fold decrease in the zinc content. The levels of all studied elementsin the meat of the chickens of this group did not exceed the maximum permissible concentrations(MPC).
