Indicators of blood quails when feeding flour from dried larvae of Lucilia Caesar

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.
