ABSTRACT:

The broiler meat production currently involves the production of ecologically safe products. The research aims to study the effect of different doses of antioxidant and adsorbent ferrocene (when excessive content of heavy metals) as feed additives in broilers’ diets based on corn, wheat and rape to increase productivity and prevention of metabolic disorders. Research methods. The objects of the study were broilers of cross “Smena-7”. Day-old chicks by analogue scale and due to their age, live weight and clinical state were divided into 4 groups of 100 birds each. Research results. During the first experiment mixed feed of the experimental birds was safe in the content of heavy metals. In their composition, different dosages of antioxidant selenopyran were tested. At this, selenopyran at a dose of 0,25 mg/kg feed is characterized by the best effect on the flock safety, due to which birds of the second test group exceeded the control by 5,5%. As for live weight gain, birds of the second test group exceeded the control by 7,6%. Different doses of adsorbent ferrocene supplementation in diets with excess content of zinc, lead and cadmium were used during the second experiment. Broilers of the second test group, which were fed ferrocene at a dose of 0,3% of feed weight and having surpassed the control counterparts by 6,6% had a higher level of the flock safety. Due to this stimulating factor broilers of the second test group had, respectively, 0,73х1012/l and 3,3 g/l more content of erythrocytes and hemoglobin in their blood. Broilers of the second test group had in samples of their blood, liver and pectorals a decrease in concentration of zinc by 1,79; 1,62 and 2,90 times; lead – by 2,44; 2,20 and 2,91 times; and cadmium – by 2,73; 2,48 and 3,60 times respectively. Keywords: broilers, heavy metals, antioxidant, adsorbent, detoxification, morphological and biochemical composition of blood.
