Description
Summary:The nutritional utility of leguminous products such as corticated marama bean (<i>Tylosema esculentum</i>) meal (CMBM) in quail diets is limited by high fibre levels. This study evaluated the impact of dietary CMBM pre-treated with fibrolytic multi-enzyme (FMENZ) on growth performance, and physiological and meat quality responses in Jumbo <i>Coturnix</i> quail. Two hundred and forty 7-day-old Jumbo quail (29.4 ± 2.72 g initial live weight) were randomly distributed to five experimental diets, with six replicate cages each (eight birds/cage). The diets were a grower diet without CMBM, and the same grower diet plus 100 g/kg CMBM pre-treated with 0, 1, 1.5, and 2% (<i>v</i>/<i>w</i>) FMENZ. Positive quadratic responses (<i>p</i> < 0.05) were recorded for overall feed intake and body weight gain in weeks 2 and 3. The control diet promoted the highest (<i>p</i> < 0.05) gain-to-feed ratio in weeks 2 and 3, and the best weight gains and glucose levels, but reduced lipase levels. Final body weights declined linearly [<i>p</i> = 0.037] with FMENZ levels. Breast pH increased linearly, while haemoglobin and 1 h post-mortem chroma showed positive quadratic effects (<i>p</i> < 0.05) with FMENZ levels. The use of the enzymes did not improve the feed value of CMBM in Jumbo quail diets.
