Abstract
Dissolving nitrogen-containing forage additives based on carbamide, grain, and mechanochemically obtained filling material has been studied. Samples were made by mechanical mixing, processing in an extruder, planetary and centrifugal activator mills. Variation of the grain and filler (straw, fats, bentonite) contents in the additive can serve as an efficient method for controlling the rate of carbamide isolation from forage additives. Conditions of mechanochemical production of forage additives are chosen according to the selection criteria, which are based on the requirement for the maximal admissible disturbance of the internal medium (acidity) of the organism during assimilation of the additive by an animal. The viability of application of mechanochemically obtained carbamide-containing additives has been shown by tests on animals.
