Description
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 diets of turkey-poults for fattening can increase the live weight of females and males of the experimental groups. By the end of the feeding, the excess in live weight of the females of the experimental groups relative to the control was 858 (8.67%) and 1211g (12.24%), males - 980 (6.17%) and 1362g (8.58%), respectively. The average daily gain in live weight of females of the experimental groups during the feeding period exceeded the control by 6.7 and 9.8 g, males - by 8.8 and 12.2 g, and feed costs per 1 kg of growth decreased: in females - by 0.06 and 0, 17 kg, for males - 0.09 and 0.18 kg. The protein level in the average meat sample increased in the I experimental group by 1.26, in the II experimental group - by 1.57%, and the cholesterol level decreased by 7.21 and 10.95%. The results of the study allowed us to conclude that the protein-lipid concentrate (PLC) from the larvae of flies of the Lucilia Caesar population contributes to an increase in the growth and development of turkey poultry, lower feed costs and improve the quality of meat
