摘要
选择１２０只１日龄ＡＡ商品健康雏鸡，随机分为４组，每组３０只。初步观察了日粮添加免疫生长促进剂Ｃ９６对血液中红细胞总数（ＲＢＣ）、比容（ＰＣＶ）、血红蛋白含量（Ｈｂ）、网织红细胞比例（ＲＣＣ）、白细胞总数（ＷＢＣ）等的影响。结果表明：肉雏鸡在１５ｄ时，日粮添加Ｃ９６为１１ｍｇ／ｋｇ，饲料的Ｃ９６组和疫苗－Ｃ９６组，与对照组和疫苗组比较，ＲＢＣ和Ｈｂ增高，ＷＢＣ显著下降，ＲＣＣ降低，ＰＣＶ无明显规律性变化；３０ｄ和４５ｄ时，添加Ｃ９６组和疫苗－Ｃ９６组的ＲＢＣ、Ｈｂ和ＰＣＶ，与对照组和疫苗组基本相近，ＷＢＣ和ＲＣＣ均比对照组和疫苗组低或明显低。但３０ｄ时疫苗组的ＷＢＣ比对照组高。整个试验期，ＲＢＣ、ＷＢＣ和ＰＣＶ随日龄的增长呈上升趋势，ＲＣＣ呈波动性下降。
One hundred and twenty healthy Arber Acres(AA) chickens at 1 day of age
were divided into four groups with 30 birds each.The effect of dietary immunegrowth promoter
C96 on red blood count(RBC),packed cell volume(PCV),hemoglobin
concentration(Hb),reticulocyte ratio(RCC),and white blood count(WBC)in blood of chickens was
investigated.The results showed that RBC and Hb increased,WBC decreased significantly,RCC
was lower,and PCV had no obvious change at 15 days of age in broiler chickens of C96 group
and vaccineC96 group with dietary C96 concentration of 11 mg/kg feed as compared with those
of the control and vaccine groups.RBC,Hb and PCV were similar among the groups.
However,WBC and RCC in C96 group and vaccineC96 group were lower or significantly lower
than in the control and vaccine groups on the 30th and 45th day,and WBC in the vaccine group
was higher than in the control on the 30th day.RBC,WBC and PCV tended to rise,but RCC
dropped fluctuently with the day of age during the whole experimental period.
