A compound for promoting livestock production and for controlling obesity in humans and animals, of the formula ##STR1## in which A represents .dbd.CH-- or .dbd.N--,

(2-aminopropyl) pyridines useful as intermediates

A pyridine derivative of the formula ##STR1## in which A stands for ##STR2## is useful in the preparation of 4-bromo-6-chloro-5-amino-2-pyridyl-ethanolamines, their physiologically tolerated salts and their N-oxides. The 4-bromo-6-chloro-5-amino-2-pyridyl-ethanolamines are useful as yield promoters in animals and as feedstuff additives to achieve higher increases in weight and improved feed utilization.

4-bromo-6-chloro-5-amino-2-substituted pyridyl compounds

The present invention relates to the use of microbiologically prepared compounds and their mixtures, which are called efomycins, as performance promoters in farm animals and processes for their preparation, and furthermore new efomycins and their mixtures as new chemical compounds. The invention also relates to microorganisms which can be used for the preparation of the efomycins and their mixtures.
