Abstract
Young Large White boars (33), weighing 27 kg, were distributed into 3 groups. Boars in treatment 1 were fed according to a liberal scheme (from 1.5 kg feed/day at 30 kg live weight up to 3.2 kg/day above 95 kg). Boars in treatment 2 and 3 were more restricted (25% restriction). Fat androsterone content was measured by radioimmunoassay for each boar at 80, 95 and 105 kg live weigth in treatment 1 and 2, and at the same age in treatment 3 as for treatment 1. No significant difference was observed between treatment for fat androsterone level. Neither age nor live weight alone, had a significant influence on androsterone production and storage. Fat androsterone was not significantly related to growth performances, but was correlated (rs = -0.59; P < 0.05) with loin/backfat ratio, a good indicator of muscle/fat ratio in carcasses.
