日粮中添加溪黄草对三黄肉仔鸡生长性能及血液生化指标的影响

试验选用1日龄三黄肉仔鸡210只随机分为7组，每组3个重复，每个重复10只，研究溪黄草对三黄肉仔鸡生长性能和血液生化指标的影响。Ⅰ组饲喂基础日粮，Ⅱ组和Ⅲ组分别在基础日粮中添加0.2%恩诺沙星粉末和1%双黄连粉末，Ⅳ～Ⅶ组分别在基础日粮中添加0.5%、1%、2%和4%溪黄草，进行为期49 d的饲养试验，测定肉仔鸡的生长性能和血液生化指标。结果表明，日粮中添加2%溪黄草可使4周龄以后三黄肉仔鸡平均日增重比空白对照组显著提高13.1%～22.7%，料重比比空白对照组降低8.1%～14.2%，其效果优于双黄连和恩诺沙星；同时可提高血清TP、GLO和GLU含量，维持血清ALB含量基本稳定，降低35日龄后鸡血清TC。

The Effects of Robdosia Serra(Maxim.) Hara on the Growth Performance and Serum Biochemical Parameter of Three-yellow Chicken

To study the effects of Robdosia serra (Maxim.) Hara on the growth performance and serum biochemical parameter of three yellow chickens, 210 one day old three yellow chickens were divided randomly into 7 groups,and each group had 3 duplicate.GroupⅠwas given basal diet.The groupsⅡand Ⅲ were added 0.2% enrofloxacin and 1% ShuangHuangLian powder to the basal diet respectively. The groups Ⅳto Ⅶ were added 1%,2% and 4% Robdosia serra (Maxim.) Hara to basal diet respectively.After 49 days of feeding，the growth performance and serum biochemical parameter were determined.The results showed that,compared to the control group,added 2% Robdosia serra (Maxim.) Hara into the basal diet could remarkably increase the daily gain from 13.1% to 22.7%,and decrease the ratio of feed/gain from 8.1% to 14.2%, and the effect was better than ShuangHuangLian and enrofloxacin. 2% Robdosia serra (Maxim.) Hara could also increase the content of serum total protien, globulin and glucose,maintain the content of serum albumin at a stable level,and decrease the content of serum total cholesterol of three yellow chickens which were 35 days old.
