“…Личинок черной львинки выращивают на субстрате из растительного сырья или пищевых отходов, причем его биоконверсия достигает 77 %, что обуславливает низкую стоимость готовой продукции [8]. Достоинством личинок, как компонента кормов, является высокое содержание в них протеина -35-48 %, при этом на долю переваримого протеина приходится 85-95 % [9]. Содержание жира в личинках также высокое и составляет 20-45 % [10].…”

“…Личинки черной львинки имеют высокую влажность -60-65 % [9], поэтому для использования в составе кормов их необходимо предварительно высушивать [11].…”

“…Для включения биомассы личинок черной львинки в состав комбикормов ее необходимо предварительно обработать. Наиболее простым способом обработки является конвективная сушка личинок при температуре 70-80 ºС и последующее измельчение [9,11]. Недостатком этого способа является разруше-ние части белков при длительном нагреве и наличие в корме непереваримого хитина.…”

“…Выделенный белок подвергают измельчению и конвективной сушке, получая высушенную массу, представляющую собой аналог рыбной муки [13]. Экспериментальные исследования показали, что протеинсодержащая мука из личинок насекомых может служить адекватной заменой рыбной муке в составе комбикормов, не уступая ей по содержанию аминокислот [9,14]. Выделенный из личинок насекомых жир также включают в рационы животных [15].…”

The experimental studies were carried out in the Rostov region of Russia in 2019. Three variants of grinded wheat grain mixed with biomass of black soldier fly larvae with raw animal material content of 10, 12.5 and 15 % by mass were extruded at varying temperature. The content of amino acids in raw material and finished extrudate was determined. It has been established that the feed mixture containing grinded wheat grain and biomass of black soldier fly larvae can be successfully extruded at the temperature of 121-135 ºC. As the extrusion temperature rises in the range of 115º-140 ºС, the content of amino acids in a finished extrudate decreases. Change in larvae content in the feed mixture does not affect the nature of the correlation between the amino acids content in the extrudate and the extrusion temperature and process behavior. It has been found that with increasing temperature the amino acids content in the extruded feed decreases with an accelerated velocity irrespective of the insect biomass content. The rational temperature range for extrusion of feed mixture containing grinded wheat grain and larvae biomass was determined within 121-127 ºC. This range provides no more than 30 % decrease in indispensable amino acids content in the extrudate. The extruded feed containing 15% of insect larvae biomass contains 9.6±0.13 % of amino acids, including 4.38±2.01 % of indispensable amino acids. Extrusion of larvae biomass mixed with grain of cereal crops is considered to be a promising direction for improving production of feed for fish and farm animals.

The aim of the research was to study the effect of compound feed with the addition of flour from dried larvae of the Lucilia Caesar fly on the morphological and biochemical parameters of the blood of young quails. The experiment was conducted on 160 Phoenix quail at the age of 10 days, of which two groups were formed according to the principle of balanced groups. The results of the tests showed that all the studied blood parameters of the experimental bird were within the physiological norm. When feeding compound feed with a protein supplement from flour of the Lucilia Caesar larva, the content of albumins in the blood serum of quails of the second group decreased by 2.0 g/l (p≤0.05)., globulins - by 1.0 g/l (p≤0.05), urea - by 0.24 mmol/l (p≤0.01). Probably, a decrease in albumins and urea in the blood of quails of the second group indicates that they are involved in protein synthesis. Gamma-glutamyltransferase (GGT) is an enzyme involved in amino acid metabolism. Catalyzes the transfer of a gamma - glutamyl residue from a gamma-glutamyl peptide to an amino acid, another peptide, or, during hydrolysis, to water. The activity of the enzyme in the blood increases in liver diseases. In our experiment, a decrease in the GGT content by 2.66 u/l in the blood of a bird receiving flour from the larvae of the Lucilia Caesar fly probably indicates an activation of amino acid synthesis in the body, which is quite consistent with the data of the average daily increments of the experimental bird. Lactate dehydrogenase (LDH) in the blood is an enzyme localized inside cells. The composition necessarily includes zinc ions. The main function is to catalyze the oxidation of lactic acid to pyruvate. In diseases accompanied by tissue damage and cell destruction, LDH activity in the blood increases. In this regard, it is an important marker of tissue destruction. According to our data, LDH levels in the blood of the experimental bird of the second group significantly decreased by 2909.75 mmol/l (p≤0.05), which indicates an improvement in the functional activity of the liver.
