Abstract
One way to improve rate and efficiency of lamb production is by the use of growth stimulating compounds. Resorcylic Acid Lactone (RAL) is a relatively new growth stimulating compound that has been shown to improve weight gains and feed efficiency of growing and finishing beef cattle. South Dakota researchers have reported 13% faster gains on 9.7% less feed for yearling steers implanted with 36 mg. RAL when compared to control steers. Two trials were conducted to determine if a 12 mg. implant of RAL would be effective in improving performance of young growing lambs
