[Biological value of Mironovskaya-808 winter wheat grown using the herbicide simazine]

The biological value of spring wheat Mironovskaya-808 grown with the use of simazine which was introduced into soil prior to appearance of shoots at doses of 0.5 and 1.0 kg/ha has been studied. The organoleptic parameters evaluated by the method of closed testing and physicochemical parameters characterizing the corn quality (protein fat, gluten and ash content, moisture, acidity) of experimental samples did not differ from those of the reference sample. Relative biological value of wheat grown with the use of simazine at a dose of 1.0 kg/ha evaluated by the test-object Tetrahymena pyriformis was slightly higher as compared to the control. The effect of test wheat samples on some parameters of protein metabolism was also studied in male rats (the content of protein and its fractions in blood serum, liver and brain as well as activity of enzymes participating in protein metabolism regulation: aminotransferases of blood serum and liver, catepsins, histidase and tryptophan oxygenase of the liver). According to the data obtained no adverse effect of spring wheat Mironovskaya-808 grown with the use of simazine on the above parameters of protein metabolism was recorded in test animals.
