Abstract: Novel antiacaridal composition comprising an effective amount of at least one compound selected from the group consisting of cis and trans, racemic and optically active isomers of a compound of the formula ##STR1## wherein R.sub.1 is selected from the group consisting of hydrogen, halogen and alkyl of 1 to 8 carbon atoms, R.sub.2 is selected from the group consisting of hydrogen, halogen, alkyl of 1 to 8 carbon atoms and alkoxy carbonyl of 2 to 8 carbon atoms and R.sub.1 and R.sub.2 taken together with the carbon atom to which they are attached form a cycloalkyl of 3 to 6 carbon atoms and R is selected from the group consisting of ##STR2## and a pharmaceutical carrier and to a method of combatting acarids in warm-blooded animals.

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.
