| [目的]比较喹赛多和喹乙醇对肉兔生产性能、肉品质及内分泌的影响。[方法] 选择120只30日龄齐卡兔,随机分成5组,每组24只,单笼饲养,对照组饲喂基础日粮、试验组分别饲喂添加50,100 mg/kg喹赛多及50,100 mg/kg喹乙醇基础日粮,试验期60 d,试验结束时测定肉兔的生产性能、肉品质及内分泌指标。[结果] 与对照组相比,各试验组肉兔的平均日增重,屠宰率和血清IGF-Ⅰ含量显著提高,料重比和腹泻率显著降低。各组胰腺指数、肝脏指数、肾脏指数和脾脏指数差异均不显著(P>0。05)。各组肉兔肌肉pH值、粗蛋白、粗脂肪(除100 mg/kg喹赛多处理组外)、水分和粗灰分含量差异均不显著(P>0。05)。试验组肉兔血清T3和T4含量均有提高,添加量为100 mg/kg时差异均显著(P<0。05)。[结论] 肉兔饲粮中添加喹赛多效果优于喹乙醇,37～90日龄肉兔饲粮喹赛多适宜添加量为100 mg/kg。 |

| Abstract: |
| 【Objective】 This experiment studied the effects of Cyadox and Olaquindox on productive performance, meat quality and internal secretion of meat rabbit 【Method】 120 thirty-day-old meat rabbits were randomly allotted to five groups by sex and weight,twenty-four rabbits each group,and housed individually.Every group received the same basal diet，supplemented with 0,50 mg/kg cyadox,100 mg/kg cyadox,50 mg/kg olaquindox and 100 mg/kg olaquindox respectively.The experiment lasted 60 days.Detected the indicators of productive performance,meat quality and internal secretion of meat rabbit after finishing the experiment. 【Result】 The results showed as following:Compared with control group,the treatments could all significantly improve daily gain,reduce feed/gain ratio,improve dressing ratio,reduce diarrhea rate，increase the concentration of IGF-Ⅰ(P<0.05)；The index of pancreas,liver,kidney and spleen had no significant difference among the five groups（P>0.05）；The pH,crude protein,crude fat(except the group of 100 mg/kg cyadox),water and crude ash of muscle of each group had no significant difference（P>0.05）；T3 and T4 were increased in each group,and there was significant difference when the 100 mg/kg cyadox or olaquindox in diets (P<0.05).【Conclusion】 The results indicated that,cyadox was better than olaquindox,and that 100 mg/kg cyadox in diets was feasible for 37-90 day-old meat rabbit. |
