Background and Aim: The Vernonia amygdalina 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 (Coturnix coturnix japonica) carcass traits and meat.

Materials and Methods: 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.

Results: Vernonia amygdalina 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.

Conclusion: Thus, VALE supplementation (20 mL/L) to quails improved carcass traits, especially cholesterol levels and carcass weights. Keywords: chemical and physical, cholesterol, fat and meat color, moisture, non-carcass percentage, protein.
