The present study was conducted to evaluate the efficacy of Mucuna pruriens seeds ethanolic extract on survival, growth performance and masculinization of Oreochromis niloticus juvenile. To this end, 600 O. niloticus juveniles with an average weight of 8.43 ± 0, 52 g were randomly distributed in 20 happas measuring 0.7 × 0.7 × 1 m placed in a 28 m3 tarpaulin tank at a density of 50 juveniles per happa and subjected to natural temperature and light conditions. Offsprings were fed with 5 experimental feeds including 02 controls (negative control (no treatment) and positive control (treatment with 17a – methyltestosterone at 60 mg/kg feed)) and 03 based on M. pruriens seeds ethanolic extract at doses of 0.15; 0.20 and 0.30 g/Kg feeds. After 60 days post-treatment, survival and zootechnical growth parameters were assessed. The study em.. View more»
