Abstract
Abstract Quinoxaline-di-N-oxides corresponding to the formula ##STR1## wherein R 1 and R 2 represent hydrogen, alkyl, phenyl, alkanoyl, benzoyl, alkoxycarbonyl, carbamoyl, cyano, amino or together a polymethylene group, Y represents hydrogen or halogen, X represents oxygen, sulphur, the sulphinyl group or the sulphonyl group, N represents 0, 1 or 2 Z represents hydrogen, alkyl, halogen-alkyl, halogen or alkoxy Are useful as supplementary feed agents having a growth-promoting action.
