摘要
以添加０．１％，０．１５％由甙、酚等组成的中草药活性物质，与抗生素类添加剂进行肉鸡饲养对比试验．结果表明：添加０．１％组的肉鸡增重、成活率、饲料转化率分别比抗生素组提高５．０％，８．９％，４．９％．４２日龄时，０．１％添加组的法氏囊显著小于抗生素组（ｐ＜０．０５），血清球蛋白含量极显著提高（ｐ＜０．０１），血钙含量以及血清碱性磷酸酶活性显著提高（ｐ＜０．０５），血清总蛋白、血红蛋白及血磷含量均有所提高．添加０．１５％组也优于抗生素组，但以０．
This paper was carried out to study the effects of herboriginated bioactive substances (HBAS, containing saponin, phenol, etc) on growth rate and some biochemical parameters in bloods in growing broilers The HBAS was added to the diets at the levels of 010% (T1) and 015% (T2), and a group added with antibiotics was designed as control At the age of 42 days, broilers for Groups T1 and control were examined for the immunerelated organs and biochemical parameters in bloods Compared to the control, addition of the HBAS at 010% resulted in an increase in growth rate, feed conversion ratio and survival rate of broilers by 50%, 49% and 89% The size of bursa Fabricii was significantly smaller (p<005) in Group T1 than in control The broilers had higher levels of calcium (p<005) and phosphorus in plasma, and higher concentrations of globulin (p<001), alkaline phosphatase (p<005), total protein, and haemoglobin in serum, when the HBAS was added instead instead of antibiotics
