METHOD TO IMPROVE THE CONSUMER QUALITY AND ENVIRONMENTAL SAFETY OF QUAIL MEAT DURING DENITRIFICATION

   Phospholipids are a kind of “solvents” of cholesterol and show a hepatoprotective effect. Also, phospholipids regulate fat and carbohydrate metabolism, improve the functional activity of the liver and its detoxification function. The study aims to study the impact of different doses of phos-pholipid lecithin preparation on economically useful indicators, meat productivity, nutritional value and environmental safety of quail meat at a subtoxic dose of nitrates in their compound feed. This article presents materials that indicate the feasibility of introducing phospholipid preparation of lecithin in the amount of 1.0 % by weight of feed under the presence of a sub-toxic dose of nitrates in the compound feed quail grown for meat. This introduction of phospholipid preparation of lecithin increases the preservation of livestock, body weight gain and reduces the cost of feed per unit gain. Poultry of the 2nd experimental group had an advantage over their control counterparts in preservation rate by 4.0 % and average daily growth by 9.50 % (P<0.05). The authors observed the benefit over the control samples in the concentration of dry substances by 0.98 and 0.99 %, protein by 0.98 and 0.97 % (P<0.05) in the examples of thigh and breast muscles of the poultry of the 2nd experimental group. The value of the protein-quality index (PQI) was higher by 13,55 % (P<0,05) in the samples of white meat from poultry carcasses of the 2nd experimental group as compared with the control counterparts. Also, the examples of poultry meat of the 2nd experimental group had better sanitary and hygienic characteristics. For instance, they had 36.83 % lower nitrate content (P<0.05) and 40.91 % lower nitrites content (P<0.05). This content indicates high denitrifying properties of phospholipid lecithin.
