Zusammenfassung: | The new compounds of the general Formula I < IMAGE > (wherein A1 stands for hydrogen, C1-4 alkyl or C4-8 cycloalkyl A2 represents C3-10 alkyl, C3-10 alkenyl, C4-8 cycloalkyl, phenyl-C1-4, alkyl, phenyl-C2-4 alkenyl phenyl optionally substituted by one or more C1-4 alkyl, C1-4 alkoxy or hydroxy naphthyl pyridyl optionally substituted by C1-4 alkyl or furfuryl and X is a valency bond or a -CO- group with the proviso that if X stands for a valency bono, A2 is other than phenyl), exhibit useful weight gain increasing and fodder utilization improving effect and can be used in animal husbandry, particularly in broyler or lamb. The compounds of the general Formula I may be prepared by methods known per se. |
