中文摘要：本研究旨在探讨不同能量和蛋白质水平日粮对石岐杂仔鸡器官指数和血液生化指标的影响。选用21日龄健康石岐杂鸡120只,随机分为4组,每组3个重复,每个重复10只,饲喂4种蛋白质(CP)和能量(DE)水平不同的玉米-豆饼型日粮,分别为:Ⅰ组(12.09 MJ/kg;18.07%)、Ⅱ组(13.09 MJ/kg;18.01%)、Ⅲ组(12.09 MJ/kg;20.08%)和Ⅳ组(13.09 MJ/kg;19.93%)。试验期为21 d。结果显示:(1)Ⅱ、Ⅳ组较Ⅰ组能显著提高胸腺、脾脏和法氏囊等免疫器官指数(P<0.05);Ⅲ组较Ⅰ组能显著提高胸腺和脾脏指数(P<0.05)。(2)Ⅱ组较Ⅰ、Ⅲ组能显著提高肝脏指数(P<0.05);(3)Ⅱ组能显著提高葡萄糖和总胆固醇的含量(P<0.05);Ⅲ组能显著提高血清总蛋白、甘油三酯和尿酸的含量(P<0.05);Ⅳ组能显著提高血清总蛋白和葡萄糖的含量(P<0.05),并提高总胆固醇、甘油三酯和尿酸含量(P>0.05)。对于22～42日龄的石岐杂鸡,以免疫器官指数作为衡量标准,能量13.09 MJ/kg、蛋白质19.93%较为适宜;以血液葡萄糖和尿酸(或其他指标)为衡量指标,能量12.09 MJ/kg、蛋白质20.08%较为适宜。

外文摘要：One hundred and twenty 21-day-old Shiqiza broilers were used to investigate the effects of dietary metabolic energy and protein level on organ indexes and serum biochemical parameters.Broilers were randomly allotted to 4 treatments with 3 replicates and 10 birds per replicate,including Group Ⅰ （12.09 MJ/kg; 18.07 %）,Group Ⅱ （13.09 MJ/kg;18.01%）,Group Ⅲ （12.09 MJ/kg;20.08 %）,Group Ⅳ （13.09 MJ/kg;19.93 %）.The trial lasted for 21 days.The results were as follows： （1）Group Ⅱ and Ⅳ significantly raised the indices of immune organs（thymus index,spleen index and bursa index）compared to ⅠI （P 〈 0.05）;group Ⅲ raised the thymus index and bursa of fabricius index significantly compared to group Ⅰ （P 〈 0.05）.（2）Group Ⅱ raised the liver index compared to group Ⅰ and Ⅲ （P 〈 0.05）.Index of the cardiac and the pancreas were no significant difference among groups; （3）Group Ⅱ notably elevated the contents of glucose （GLU） and total cholesterol （TC）（P 〈 0.05）;group III remarkably sublimated the serum total protein（TP）,triglye- eride（TG） and uric acid（UA）（P 〈 0.05）;group IV significantly the contents of sublimated the contents of serum TP and GLU （P 〈 0.05） ,and raised the contents of TG,TC and UA （P 〉 0.05）.The result indicated that the diet nutrition of DE 13.09 MJ/kg,CP 19.93 % was suitable on organs indices;the nutrition level of DE 12.09 MJ/kg,CP 20.08 % was suitable of blood biochemical indices.
