Abstract
The article presents the results of laboratory tests for the presence of heavy metals and pesticides when adding a mineral feed additive to the diet of birds. The relevance of the study is related to the cultivation of healthy and highly productive quails in order to ensure food security of the Republic of Kazakhstan. The conducted studies of meat to assess the indicators for the presence of heavy metals and pesticides for the purpose of using a mineral feed additive on experimental birds (quails) allowed us to obtain the following results: pesticides in all samples - less than 0.005 mg/kg, mercury and arsenic - less than 0.0002, the presence of lead in four samples did not reach critical indicators. A comprehensive analysis of the results obtained on the basis of scientific and experimental studies of meat to assess the indicators for the presence of heavy metals and pesticides showed the harmlessness of mineral feed additives when used in the diet of quails.
