Development of a new technology for improving the quality of food raw materials of animal origin

The use of silver, which is a potent antibiotic, has attracted our interest in testing it as an anti-stress drug for technological stresses such as transportation and pre-slaughter handling. Based on the results, we have developed a new technology for improving the quality of food raw materials, including the intramuscular injection of ultrafine particles (UFP) of silver at a dose of 0.01 mg / kg of live weight. This allows improving the quality characteristics of by-products (liver, kidneys, lungs), which is characterized by an increase of both saturated fatty acid (namely, palmitic one) by 23.7% and unsaturated (oleic) acid by 38.6%; and at a dosage of 0.05 mg / kg of live weight - in terms of myristic, palmitic and oleic fatty acids compared to the control group without the drug administration. This contributed to a decrease in the activity of free radical oxidation in animals and increased adaptive abilities. However, the best adaptive qualities with an increase in the amount of corresponding fatty-acids were animals who were intramuscularly injected with UFP of silver at a dose of 0.01 mg/kg of body weight.
