Animal feed and process

Abstract

A process for increasing production in meat-producing, egg-laying or milk-producing animals comprising feeding a compound of the formula: ##STR1## wherein R is a member selected from the group consisting of hydrogen, R.sub.5, ##STR2## wherein R.sub.5 is alkyl of from 1 to 8 carbon atoms, inclusive, including isomeric forms thereof; alkenyl of from 2 to 8 carbons, inclusive, including isomeric forms thereof, cycloalkyl of from 3 to 7 carbon atoms; or R is lower acyl wherein acyl is up to and including 5 carbon atoms; R.sub.1 is a member selected from the group consisting of R.sub.5 and ##STR3## wherein R.sub.6 is selected from the group consisting of hydrogen, ##STR4## or lower acyl wherein acyl is up to and including 5 carbon atoms; R.sub.2 is a member selected from the group consisting of hydrogen, R.sub.5, bromo or chloro; R.sub.3 and R.sub.4 are the same or different and are selected from the group consisting of hydrogen, provided that R.sub.3 and R.sub.4 are not both hydrogen; R.sub.5, cycloalkyl of from 3 to 8 carbon atoms, alkyl substituted cycloalkyl of the formula ##STR5## wherein n is an integer of from 2 to 7, inclusive and R.sub.7 is a member selected from the group consisting of hydrogen and alkyl of from 1 to 5 carbon atoms, inclusive, including isomeric forms thereof; alkenyl of from 2 to 8 carbon atoms, inclusive, including isomeric forms thereof, aralkyl wherein Ar is a member selected from the group consisting of phenyl, substituted phenyl wherein 1 or 2 hydrogens are replaced with chlorine, fluorine, bromine, iodine, R.sub.5, --OR.sub.5 or --CF.sub.3 and the substituents can be the same or different, and alkyl is from 1 to 4 carbon atoms, inclusive, including isomeric forms thereof; and R.sub.3 and R.sub.4 taken together with ##STR6## is a heterocyclic moiety of from 4 to 8, inclusive, ring atoms and 1 or 2 hetero atoms selected from the group consisting of nitrogen, oxygen or sulfur or substituted heterocyclic moiety wherein 0, 1, 2 or 3 of the carbon atoms of the heterocycle are substituted with R.sub.5 in combination with a nutrient feed.
