ABSTRACT The invention relates to new carbazic acid derivatives, a process for the preparation thereof and compositions - particulary feed additives and animal feeds - containing the same. The new compounds according to the invention correspond to the general formula /I/ R1 = N - NH - COOR3 /I/ wherein R1 stands for a C7-12 cycloalkylidene group, an indanylidene group or a group of the general formula /IX/ Image /IX/ wherein A reprssents a phenyl group optionally carrying one or more identical or different substituent/s/ selected from the group consisting of nitro, hydroxy, C1-4 alkoxy, C1-4 alkyl, amino or C1-4 alkoxycarbonylhydrazino; a phenyl-/C1-4 alkyl/, a C1-16 alkyl, a C3-7 cycloalkyl or an indolyl group; R2 denotes a hydrogen atom, a C1-16 alkyl or a C3-7 cyclo- alkyl group; and R3 represents a C1-4 alkyl group, The compositions - particularly fodder additives and fodders - according to the invention comprise as active ingredient an amount of 1 ppm to 85% by weight of a compound of the general formula /I/, wherein R1 and R3 are as defined above, or a biologically acceptable salt thereof in admixture with suitable inert solid or liquid carriers or diluents and can be used to advantage in animal husbandry.
