The Del. leaf extract (VALE) contains several natural antioxidants, including flavonoids, which effectively ameliorate cholesterol levels while improving quail carcass traits and meat quality. This study aimed to evaluate the effects of VALE on Japanese quail () carcass traits and meat.
In total, 260 Japanese quails (aged 5 weeks and body weight = 129.1 ± 2.2 g) were raised in an open-sided house and randomized to four VALE treatments: T0: Control, T1: 10 mL/L, T2: 20 mL/L, and T3: 10 mL/L in drinking water. After 12 weeks, carcass traits and chemical and physical meat qualities were evaluated.
leaf extract in drinking water exerted significant effects (p < 0.05) on carcass weight, cholesterol levels, and meat water holding capacity (WHC) without significantly affecting carcass and non-carcass percentages, moisture, protein, fat, and meat color qualities. The highest carcass weights and lowest cholesterol levels were identified in the T2 group, while WHC improved in the T3.
Thus, VALE supplementation (20 mL/L) to quails improved carcass traits, especially cholesterol levels and carcass weights.
德尔叶提取物（VALE）含有多种天然抗氧化剂，包括类黄酮，可有效改善胆固醇水平，同时改善鹌鹑的胴体性状和肉质。本研究旨在评估VALE对日本鹌鹑胴体性状和肉品质的影响。
总共260只日本鹌鹑（5周龄，体重 = 129.1 ± 2.2克）饲养在开放式鸡舍中，并随机分为四种VALE处理组：T0：对照组，T1：10毫升/升，T2：20毫升/升，T3：10毫升/升，添加于饮用水中。12周后，评估胴体性状以及肉的化学和物理品质。
饮用水中的叶提取物对胴体重量、胆固醇水平和肉的持水能力（WHC）有显著影响（p < 0.05），但对胴体和非胴体百分比、水分、蛋白质、脂肪和肉色品质无显著影响。T2组的胴体重量最高，胆固醇水平最低，而T3组的WHC有所改善。
因此，向鹌鹑补充VALE（20毫升/升）可改善胴体性状，尤其是胆固醇水平和胴体重量。
