APPLICATION OF GLUTAMINE DERIVATIVES FOR PRODUCING AN ANIMAL FEED ADDITIVE Russian patent published in 2022 - IPC A23K20/142 C07D295/185 

FIELD: animal husbandry.

SUBSTANCE: invention relates to animal husbandry, in particular, to production of feed additives and feeds. Proposed is an application of a glutamine derivative by the formula (I) , wherein Y constitutes an OC₁-C₂₀ alkyl group or OH; X constitutes an NHC₁-C₂₀ alkyl group; R¹ constitutes H; R² constitutes R^2aC(=O) or R^2bC(=O); R^2b constitutes a C₁-C₂₀ alkyl group; R^2a constitutes a C₅-C₁₂ aryl group or a C₅-C ₁₂ aryl group, optionally substituted with one, two, three, four, or five R⁴; R⁴ constitutes -OH, -NH₂, -NO₂, -CN, -SH, -X₂, a -C₁-C₅ alkoxy group, a -C₁-C₅ alkyl group, or -a C₁-C₅ alkyl group substituted with X₂, wherein X₂ is selected from F, Cl, Br, or I, a racemate thereof, a stereoisomer thereof, a geometric isomer thereof, a tautomer thereof, a solvate thereof, or a feed-acceptable salt thereof for producing animal feed additives for raising the productivity of animals and the effectiveness of digestion of the feed additive.

EFFECT: application of feed additives containing the glutamine derivative by the formula (I), a racemate thereof, a stereoisomer thereof, a geometric isomer thereof, a tautomer thereof, a solvate thereof, or a feed-acceptable salt thereof in the process of rearing animals ensures improved digestion of feeds and accelerated growth of animals without a toxic effect on the body of the animal.
