It was established that feeding up to ewe's diet additives of lysine, methionine and sulphur is accompanied by intensification of metabolism in ewe's organism as evidenced an increase of urea content, phosphorus, calcium concentration, total lipids, phospholipids and triacylglycerols. Feeding these supplements to sheep leads to increased milk productivity in ewes and the improving biological value of milk by raising the protein, fat, carbohydrates contents and calories. As a result the lamb's body weight was bigger by 4,0 - 10,4 % compared with the control group. The wool growth intensity increased by 17,9 - 27,3 % and its physical and chemical properties, including strength fibers (5,5 - 7,5 %) and protective properties of grease was preferable. It was established that the effect of lysine is directed to the formation of meat qualities, but sulfurcontained compounds (methionine, sodium sulfate) - on wool productivity. Investigations of the adsorption capacity of native and functionalized wool were conducted. It was established that the efficiency of adsorption of pollutants by oxidized wool four times higher compared to the native wool. Product Description popup.authors Гавриляк В.В. Параняк Н.М.
