METHOD OF PRODUCING DERIVATIVES OF CYCLOALKYLIDENHYDRAZINE

The invention relates to new cycloalkane derivatives, a process for the preparation thereof and compositions-particularly feed additives and animal feeds-containing the same. The new compounds of the present invention correspond to the general formula I I wherein n is 3, 4, 5 or 6; R denotes a phenyl group optionally carrying one or more substituent/s/ selected from the group consisting of halogen, lower alkoxy and lower alkyl; R1 and R2 each represent hydrogen or form together a valence bond; R3 represents lower alkoxy or a phenyl optionally substituted by one or more C1-12 alkoxy. The fodder additives and fodders according to the invention contain as active ingredient an amount of 1 ppm to 85% by weight of a compound of the general formula I in admixture with inert solid or liquid carriers or diluents and can be used to advantage in animal husbandry.
