Effect of methanabol (17βhydroxy‐17α methyl‐l, 4‐androstadiene‐3‐one) on growth and breast muscle nucleic acid content in the chicken

Abstract
1. The effect of methanabol (17β hydroxy‐17α methyl‐1,4‐andro‐stadiene‐3‐one) on growth and breast muscle nucleic acid in White Rock chickens grown to 8 weeks of age was tested. Methanabol was administered by mouth daily during this period at 0.05 mg/kg body weight in aqueous suspension to 30 birds, with appropriate controls. 2. Growth was significantly increased by methanabol. 3. Breast muscle RNA was significantly increased by methanabol but DNA was not affected.
