Abstract

ABSTRACT This study evaluated the effect of dietary red grape pomace (RGP) powder on physiological and meat quality responses of Japanese quail. Three hundred quail birds were randomly distributed to five dietary treatments formulated as follows: a negative control diet without antibiotics (NegCon); a positive control diet with antibiotics (PosCon); NegCon diluted with RGP at a rate of 1.5% (RGP15), 3.5% (RGP35), and 5.5% (RGP55). Diet RGP55 promoted higher (p < 0.05) overall feed intake (934.3 g/bird) than diet RGP35 (809.2 g/bird). The NegCon diet promoted the highest breast meat lightness (L*) value (46.1) while the lowest value (42.7) was observed in RGP35 meat. In conclusion, quail birds reared on RGP-containing diets had similar physiological and meat quality parameters as those on the antibiotic-containing diet. An optimum inclusion level could not be determined using the physiological and meat quality responses, suggesting a need to investigate higher levels of dietary RGP.

分级红葡萄渣粉对日本鹌鹑生理和肉质反应的影响

摘要本试验旨在研究饲粮中添加红葡萄渣(RGP)粉对日本鹌鹑生理和肉质反应的影响。将300只鹌鹑随机分为5种饲粮处理:阴性对照饲粮不含抗生素(NegCon);阳性对照饮食加抗生素(浦项康);用RGP稀释NegCon，稀释率分别为1.5% (RGP15)、3.5% (RGP35)和5.5% (RGP55)。饲粮RGP55促进总采食量(934.3 g/只)高于饲粮RGP35 (809.2 g/只)(p < 0.05)。NegCon组胸肉轻度(L*)值最高，为46.1,RGP35组胸肉轻度最低，为42.7。由此可见，饲粮中添加rgp的鹌鹑与饲粮中添加抗生素的鹌鹑具有相似的生理和肉质参数。根据生理和肉质反应，无法确定最佳的添加水平，这表明有必要研究更高水平的膳食RGP。
