1. The purpose of this study was to determine the metabolisable energy of high-protein distiller's dried grains with solubles (HP-DDGS) for meat quail (Coturnix coturnix coturnix; Experiment I) and evaluate the effects of dietary levels of HP-DDGS on animal performance, carcase characteristics, meat quality, and organ weights (Experiment II). 2. In Experiment 1, 96 meat quail were distributed in a completely randomised design with two treatments (reference or test diet) and six replicates of eight birds. The experimental period consisted of 5 d adaptation, followed by 5 d total excreta collection. The experimental diets consisted of a reference (control) and a test diet formulated with 800 g/kg reference diet and 200 g/kg HP-DDGS. 3. In Experiment 2, 612 meat quail were distributed in a completely randomised design fed one of six dietary levels of HP-DDGS (0, 85, 170, 255, 340, or 425 g/kg) as a replacement for soybean meal. At 42 d of age, birds were slaughtered and evaluated for carcase yield, organ weights, and meat quality. 4. Apparent metabolisable energy values corrected for nitrogen retention of HP-DDGS were 12.5 and 12.3 MJ/kg for males and females, respectively. 5. In the starter phase (1–21 d of age), increasing dietary HP-DDGS levels had a quadratic effect on body weight (BW) (P = 0.020) and body weight gain (BWG) (P = 0.019). The maximum BW and BWG values were estimated to be achieved with 296.0 and 296.2 g/kg dietary HP-DDGS, respectively. Overall (1–42 d of age), increasing dietary HP-DDGS levels in replacement of soybean meal did not affect animal performance, carcase yield, meat quality or organ weight in meat quail. 6. It was concluded that dietary HP-DDGS can fully replace soybean meal in meat quail diets without affecting growth performance, carcase yield, meat quality or organ weight. [ABSTRACT FROM AUTHOR] |
