1. for the preparation method of the granular core of animal nutrition, described core comprises:

  • -active quantities is more than or equal to the hydrophilic active principle of 60% weight ratio, and described hydrophilic active principle is selected from lysine and salt thereof,-at least one is fusible binding agent, the fatty acid that is selected from polyethylene glycol wax class, paraffin class, oils or fats, contains 10-32 carbon atom, corresponding single-, two-and three-ester class, and corresponding alcohols,-at least one plasticizer, is selected from cellulose or derivatives thereof, and-starch,Described method comprises that (a) first step is by each composition mixing, (b) second step by gained mixture the extruder by being equipped with one or more moulds particularly single screw rod or double screw extruder melt extrude, to obtain shaft, described melt extrude by described fusible binding agent realize, and (c) the 3rd step is carried out round as a ball to described shaft, described method was characterised in that before extruding described mixture the preliminary step that described composition is dried altogether-is ground, described common-grind and carry out being no more than at the temperature of 50 ℃
