摘要
试验研究了在日粮中添加100～300mg／kg姜黄提取物对文昌鸡生长性能、血液指标和免疫器官指数的影响。300只1日龄雏鸡集中育雏2周后，随机分为4个处理组，每个处理5个重复，每个重复15只。T0组饲喂基础日粮，T100、T200和T300组分别在基础日粮中添加100、200mg／kg和300mg／kg姜黄提取物，饲养至12周龄。结果表明，日粮中添加100～200mg／kg姜黄提取物能提高9～12周龄文昌鸡生长性能。日粮添加姜黄提取物对文昌鸡血液指标无显著影响（P〉0．05），但可提高9～12周龄文昌鸡胸腺和法氏囊指数。上述结果提示，在日粮添加100～300mg／kg姜黄提取物可促进和提高文昌鸡后期生长性能和免疫器官指数。
The purpose of the study was to determine the effect of increasing dietary levels of turmeric rhizome extract （TRE） on growth performance, blood biochemical parameters and immune organ index- es of Wenchang broiler chickens. Three hundred, 1-day-old Wenchang broiler chickens were brooded together for 2 weeks, and then randomly allocated into four treatment groups with five replicates of 15 birds each. Birds were fed a basal diet of corn and soybeans supplemented with TRE at 0, 100, 200 mg/kg and 300 mg/kg for 12 weeks. The results revealed that a TRE-supplemented diet increased the growth performance of birds from 9 to 12 week. Diet supplementation with TRE at 100 to 300 mg/kg had no significant effect （P〉0.05） on the blood biochemical parameters of birds. However, diet supple- mented with TRE increased the organ indexes of thymus and bursa of birds. In conclusion, dietary TRE supplementation increased the growth performance and enhanced the development of immune organs of Wenchang broiler chickens.
