Novel zootechnical compositions

Abstract

Novel zootechnical compositions and a method of upgrading of domestic animals such as cattle by administering under the skin of cattle a mixture of an anabolisant steroid of the formula ##SPC1## Wherein R is alkyl of 1 to 4 carbon atoms and X is selected from the group consisting of hydrogen, lower alkyl optionally substituted with phenyl, lower alkenyl, lower alkoxy-lower alkyl, lower alkyl-thialower alkyl, cycloalkyl of 3 to 7 carbon atoms, cycloalkyl lower alkyl, heterocycloalkyl, cyclic alkyl wherein the ring is derived from an unsaturated nitrogen, oxygen or sulfur heterocycle of 5 to 7 carbon atoms and acyl of an organic carboxylic or carbonic acid of 1 to 18 carbon atoms and an estrogenic steroid of the formula ##SPC2## Wherein R is alkyl of 1 to 4 carbon atoms, R.sub.1 is selected from the group consisting of hydrogen, alkyl of 1 to 5 carbon atoms and cycloalkyl of 3 to 7 carbon atoms, A is selected from the group consisting of hydrogen and .beta.-alkoxy of 1 to 4 carbon atoms, Y is selected from the group consisting of hydrogen, methyl, ethynyl and haloethynyl and X.sub.1 is selected from the group consisting of hydrogen and acyl of an organic carboxylic or carbonic aliphatic or cyclanic acid of 1 to 10 carbon atoms.
