摘  要：
探讨了不同水平苜蓿黄酮对崇仁麻鸡母雏后期生长性能、屠宰性能及肌肉化学成分的影响。选用30日龄健康崇仁麻鸡母雏480只,随机分为4组,每组4个重复,每个重复30只。Ⅰ组、Ⅱ组、Ⅲ组、Ⅳ组分别在基础饲粮中添加0,0.05%,0.10%和0.15%的苜蓿黄酮。预试期5d,正试期28d。试验结果表明:与对照组相比,试验组添加苜蓿黄酮后平均日采食量有下降趋势(P>0.05),日增重和饲料报酬提高(P>0.05),其中以组Ⅲ效果最好,日增重比对照组提高3.27%(P>0.05),料重比降低5.82%(P>0.05)。苜蓿黄酮对崇仁麻鸡母雏屠宰性能和肌肉蛋白质、肌苷酸含量无影响(P>0.05),但抑制了鸡只的脂肪沉积,其中Ⅲ组的皮下脂肪厚度和肌间脂肪宽度分别比对照组低26.22%和20.53%(P<0.05),Ⅳ组的腹脂率和腿肌脂肪含量分别比对照组低11.66%(P<0.01)和9.35%(P<0.05)。由上可知,生长后期的崇仁麻鸡母雏饲粮中添加苜蓿黄酮后,生产性能不受影响而平均日采食量下降,脂肪沉积减少,综合考虑以0.10%的苜蓿黄酮添加量较为适宜。

摘  要：
To investigate the effects of alfalfa flavones on the growth performance,slaughter performance and muscular ingredients of female Chongren chickens at a late growth stage,480 30-day-old healthy female Chongren chicken were randomly allotted to 4 groups with 4 replicates per group and 30 birds per replicate.The groups of Ⅰ,Ⅱ,Ⅲ and Ⅳ were fed the basal diet supplemented with 0,0.05%,0.10% and 0.15% alfalfa flavones respectively.There was a pretrial period of 5 days followed by an experimental period of 28 days.Compared with the control group,the average daily feed intake(ADFI) of the treatment groups supplemented with alfalfa flavones had a slight tendency to decrease(P>0.05).There were slight increasing trends in the average daily gain(ADG) and feed conversion efficiency in the treatment groups(P>0.05).The best effect on increase of ADG(3.27%) was in Group Ⅲ,while the ratio of feed/gain(F/G) decreased by 5.82%(P>0.05).There were no significant differences in the slaughter contents of protein and inosine monophosphate(IMP) in muscles of the groups(P>0.05),but a supplement of alfalfa flavones significantly inhibited fat deposition.The subcutaneous fat thickness and intermuscular fat width of groups Ⅲ were lower than those of the control group by 26.22% and 20.53%(P<0.05) respectively.The percentage of abdominal fat and content of fat in thigh muscle of groups Ⅳ were lower than those of the control group by 11.66%(P<0.01) and 9.35%(P<0.05) respectively.In conclusion,alfalfa flavones reduced ADFI and fat deposition without affecting the growth performance at the later growth stage of female Chongren chickens.The best alfalfa flavone dose was 0.10%.
