The effect of a protein feed additive based on the larvae of the Hermetia illucens fly on the amino acid and fatty acid compositions of quail eggs

In the course of the conducted research, it was found that the use of Black Soldier Fly larvae in dried and native forms in feeding laying quails led to an improvement in the biological and nutritional values of eggs. The amount of essential amino acids in quail eggs of experimental groups II and III increased by 5,1 and 4,4 % compared with the control. The amount of interchangeable amino acids in quail eggs of experimental groups II and III increased by 5,1 and 7,3 % compared with control analogues. The proportion of saturated fatty acids in quail eggs fed with dried forms of insect culture increased significantly: capric acid - by 80%, lauric acid - by 23,1 %, myristic acid - by 13,1 % compared with the control. In the eggs of quails fed with native forms of Black Soldier Fly larvae, the proportion of lauric acid significantly decreased by 42,3 %, myristic acid by 15,5 %, stearic acid by 12,2 %, the proportion of lenolic acid increased by 25,2 %, and linolenic acid by 3,5 times. The proportion of arachic acid in the eggs of quails that consumed the native form of the insect culture was 5 times higher than its proportion in the eggs of quails that used dried forms of the insect culture.
