The growth rate of an animal is stimulated by administering to the animal a growth-promoting amount of a compound of the formula
wherein
- R₁, R₂, R₃, R₄ and R₅, which can be the same or different, are each selected from the group consisting of hydrogen, alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms and halogen;
- X is selected from carbonyl and a ketal group of the formula:
wherein R₆ and R₇, which can be the same or different, are each selected from hydrogen and alkyl having 1 to 3 carbon atoms;
- A is a linear or branched alkylene having from 1 to 8 carbon atoms;
- Y is selected from OQ (wherein Q is hydrogen, C₁-C₄-alkyl or a cation of an alkali or earth alkali metal, or of a non-toxic organic base); and a group of formula -NR₈R₉ , wherein R₈ and R₉ are hydrogen, C₁-C₄-alkyl, C₂-C₄ 2-hydroxyalkyl or, heterocyclic ring optionally including other heteroatoms; provided that, when X is a ketal group and A is ethylene, the group R₈R₉ is a group other than morpholino.
