Abstract

The purpose. To study features of growing ducks on aboriginal feedstuffs at different systems of their growing and to develop methods of production of ecologically safe duck meat in terrains with different density of radioactive contamination of soils. Methods. 2 groups of young animals of ducks are generated: I group (control) – non-exercise growing in poultry yards with easy approach to water in pans; II group (test) – exercise growing on the natural bounded pools. Determination of specific activity of 137Cs in feedstuffs, water and killing products of an auk was carried out with the use of AMA-05E and BDEG-20R, the concentration of heavy metals was measured using atomic absorption method on spectrophotometer S-115M. Results. In conditions of extensive growing experimental ducks in II and III zones of radioactive contamination on aboriginal feedstuffs and unbalanced rations on calcium, phosphorus and microelements they got meat of ducks with concentration of 137Cs did not exceed allowances (DU-2006=200 Becquerel/kg) and fluctuated within the limits of 9,3 — 75,9 Becquerel/kg. Concentration of lead and cadmium in muscles and liver of experimental ducks did not exceed maximum concentration limit. Conclusions. Ecological safety of production of duck meat as one of main products of feed of population in regions with radioactive contamination was proved theoretically and in practice.
