Abstract
Abstract This disclosure describes a combination treatment for ruminants to synergistically enhance the growth rate thereof and improve the efficiency of feed utilization thereby. The treatment involves, orally administering a growth-enhancing amount of the antibiotic AV290, antibiotic AV290 sulfate, antibiotic AV290-syntan complex, antibiotic AV290-alkyl sulfate complex and/or antibiotic AV290 alkylated derivative, to ruminants which have been parenterally or orally treated with a growth-enhancing amount of a selected steroid or steroidal composition.
