| Summary: | The article presents comparative studies of the meat productivity of geese of the Lindovskaya breed when zeolite and nanostructured zeolite feed additives are introduced into their diets. It was shown that the use of zeolite contributed to an increase in the live weight of geese by 4.0 %, the use of different doses of nanostructured zeolite led to an increase by 6.2–10.2 % (P≤0.05), in comparison with control analogues. When using zeolite in meat, the content of zinc and copper salts decreased by 28.0 and 13.1 %. The introduction of nanostructured zeolite into the diet led to a decrease in zinc content by 27.5–31.3 % and that of copper by 27.1–48.6 % compared with the control. The meat of birds of all groups corresponded to hygienic quality requirements for the content of chemical elements.
