Abstract

The nutritional utility of leguminous products such as corticated marama bean () 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 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% (/) FMENZ. Positive quadratic responses ( < 0.05) were recorded for overall feed intake and body weight gain in weeks 2 and 3. The control diet promoted the highest ( < 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 [ = 0.037] with FMENZ levels. Breast pH increased linearly, while haemoglobin and 1 h post-mortem chroma showed positive quadratic effects ( < 0.05) with FMENZ levels. The use of the enzymes did not improve the feed value of CMBM in Jumbo quail diets.

摘要

去皮马拉马豆()粕(CMBM)等豆科产品在鹌鹑日粮中的营养效用受到高纤维水平的限制。本研究评估了用纤维分解多酶(FMENZ)预处理的日粮CMBM对巨型鹌鹑生长性能、生理和肉质反应的影响。将240只7日龄巨型鹌鹑(初始活重29.4±2.72克)随机分配到五种实验日粮中,每种日粮设六个重复笼(每笼八只鸟)。日粮分别为不含CMBM的育雏日粮,以及添加了0、1、1.5和2%(/)FMENZ预处理的100克/千克CMBM的相同育雏日粮。在第2周和第3周,总采食量和体重增加呈正二次反应(<0.05)。对照日粮在第2周和第3周促进了最高(<0.05)的料重比,以及最佳的体重增加和葡萄糖水平,但降低了脂肪酶水平。最终体重随FMENZ水平呈线性下降[=0.037]。胸肌pH值呈线性增加,而血红蛋白和宰后1小时色度随FMENZ水平呈正二次效应(<0.05)。在巨型鹌鹑日粮中使用这些酶并没有提高CMBM的饲料价值。
