The present invention relates to new carbazates of the general formula (I), ##STR1## wherein A is C.sub.3-10 alkyl, C.sub.3-10 alkenyl, C.sub.2-10 haloalkyl, trifluoromethyl, phenyl-C.sub.1-3 alkyl, phenyl-C.sub.2-3 -alkenyl, naphthyl-C.sub.1-3 alkyl; phenyl optionally substituted by one or more identical or different substituent(s) selected from C.sub.1-4 alkyl, halogen, C.sub.1-4 alkoxy and hydroxy; C.sub.3-7 cycloalkyl-C.sub.1-3 alkyl; optionally nitro-substituted furyl; diphenyl-hydroxy-methyl or indazolyl optionally substituted by one or more C.sub.1-4 alkoxy group(s) and R represents C.sub.1-4 alkyl, with the proviso that if R stands for ethyl, A is other than tertiary butyl, and acid addition salts thereof, a process for the preparation thereof and feed-additives comprising the same. The compounds of the general formula (I) may be used in animal husbandry due to their weight-gain increasing and fodder utilization improving effect.
本发明涉及通式(I)的新的卡巴曾类化合物,其中A是C.sub.3-10烷基、C.sub.3-10烯基、C.sub.2-10卤代烷基、三氟甲基、苯基-C.sub.1-3烷基、苯基-C.sub.2-3烯基、萘基-C.sub.1-3烷基;苯基可选地被一个或多个相同或不同的取代基(所选自C.sub.1-4烷基、卤素、C.sub.1-4烷氧基和羟基)取代;C.sub.3-7环烷基-C.sub.1-3烷基;可选地硝基取代的呋喃基;二苯基-羟甲基或可选地被一个或多个C.sub.1-4烷氧基取代的吲唑基;R代表C.sub.1-4烷基,但如果R代表乙基,则A不是三丁基;以及它们的酸盐加成物、制备它们的方法和包含它们的饲料添加剂。通式(I)的化合物由于其增重和饲料利用率提高的作用,可用于畜牧业。
