INFLUENCE OF PROBIOTICS IN THE COMPOSITION OF FEED SUBSTRATE ON THE AMINO ACID PROFILE OF HERMETIA ILLUCENS LARVES

, ,
 39-47 p.
The use of probiotics Bacillus subtilis B-8130 and Bacillus licheniformis B-4162 as part of the feed mixture in the cultivation of larvae of the black soldier fly Hermetia illucens influenced the features of the amino acid profile of the larvae. The greatest impact was caused by B. licheniformis B-4162, which caused a statistically significant decrease in the level of 10 of the 18 essential amino acids, including the sulfur-containing amino acids cystine and methionine. B subtilis B-8130 demonstrated an unreliable tendency to decrease the total amino acid content, but statistically significantly reduced the cystine content compared to the control.
The revealed changes in the amino acid content in the larvae occurred against the background of an increase in their mass compared to the control larva. It is assumed that the decrease in the level of amino acids is associated with their expenditure on the formation of glucose and metabolic energy in a more intensively developing larva on a feed mixture with a probiotic.
