EXCHANGE PROCESSES IN TURKEY ORGANISM BY USING THE PROTEIN FROM THE LARVAS OF THE FLIES OF THE POPULATION LUCILIA CAESAR

Romanenko Еvgenia Аlexandrovna, Istomin Аlexey Igorevich

One of the urgent directions of finding promising raw ingredients in the feeding of farm animals and birds is the use of larvae of flies as a source of alternative protein. In Russia, LLC « New Biotechnology » is engaged in the processing of organic waste using the larvae of the flies of the population Lucilia Caesar under a project accredited at the Skolkovo Innovation Center, which, after a global reconstruction, started its production. The use of flour from larvae of flies in feeding poultry, including turkeys, is a new direction that is becoming more widespread among leading world producers. The authors established the high efficiency of using protein-lipid concentrate (PLC) from the larvae of flies of the population Lucilia Caesar in the production of cross BIG-6 turkey meat. It is proved that the use of the studied additives in the amount of 5.0 and 7.5% in the diet of turkey-poults for fattening can increase the digestibility of nutrients of the feed. The digestibility of crude feed protein by turkeys of the experimental groups increased by 2.3 and 3.1%, crude fat - by 1.9 and 2.7%, NFE - by 2.7 and 3.8%. The deposition of nitrogen in the organism of turkeys exceeded the control by 5.07 and 7.43%, and its use from the accepted by 1.52 and 2.28%. The increase in digestibility of feed nutrients contributed to the activation of metabolic processes in the body of turkeys. The red blood cells in the blood of turkeys of the experimental groups increased by 6.63 and 7.53%, the concentration of hemoglobin increased by 4.48 and 7.84%. The total protein content in the blood serum of turkeys of the experimental groups increased by 10.17 and 15.59%, and the level of the albumin fraction - by 13.49 and 20.69% relative to the control, which is a reserve for the growth of body tissues, determines the growth rate of animals. The content of calcium and phosphorus, characterizing the level of mineral metabolism in the body, increased by 18.15 and 19.22%; 12.84 and 14.86% compared with the control. The results of the study allowed us to conclude that the protein-lipid concentrate (PLC) from the larvae of flies of the population Lucilia Caesar helps to improve the digestibility of feed nutrients, the use of nitrogen, and the activation of protein and mineral metabolism.
