The effects of 0, 40 and 80 g/kg alfalfa meal on growth performance, carcass traits and meat quality of Chinese yellow-feathered broilers fed diets containing or lacking wheat (0 or 200 g/kg) as part of the energy source, were examined using random design with a 2 × 3 factorial arrangement of treatments. Dressing percentage and semi-eviscerated proportion were lower, and meat color a* (redness) value was higher in birds fed diets containing wheat than diets lacking wheat (P < 0.05). Drip loss was reduced by the addition of alfalfa meal to diets containing or lacking wheat (P < 0.05). Average sensory score of breast meat was higher in chickens fed corn-based diets than in those fed wheat (P < 0.05). Meat from those supplemented with 40 g/kg alfalfa meal had better taste than the other two levels (P < 0.05). The inclusion of wheat significantly reduced the activities of creatine kinase and calpain of breast muscle (P < 0.05). In conclusion, Chinese yellow-feathered broilers fed diets containing wheat had better meat color and lower drip loss than those fed the diets without wheat, and adding 40 g/kg alfalfa meal generally improved meat quality and taste.
采用随机设计和2×3析因处理安排，研究了0、40和80 g/kg苜蓿草粉对以含或不含小麦（0或200 g/kg）作为能量来源的日粮饲喂的中国黄羽肉鸡生长性能、胴体性状和肉品质的影响。与不含小麦的日粮相比，饲喂含小麦日粮的鸡的屠宰率和半净膛率较低，肉色a*（红色度）值较高（P<0.05）。在含或不含小麦的日粮中添加苜蓿草粉均可降低滴水损失（P<0.05）。饲喂玉米型日粮的鸡的胸肉平均感官评分高于饲喂小麦型日粮的鸡（P<0.05）。添加40 g/kg苜蓿草粉的鸡肉口感优于其他两个添加水平（P<0.05）。添加小麦显著降低了胸肌中肌酸激酶和钙蛋白酶的活性（P<0.05）。总之，与饲喂不含小麦日粮的鸡相比，饲喂含小麦日粮的中国黄羽肉鸡具有更好的肉色和更低的滴水损失，添加40 g/kg苜蓿草粉总体上可改善肉品质和口感。
