摘 要:为研究不同日粮结构对京红1号蛋雏鸡生长性能及抗体水平的影响,试验选用健康、体重相近的0日龄京红1号蛋雏鸡720只,随机分成2个处理组,每组360只,每组3个重复,每个重复120只,对照组饲喂基础日粮,试验组日粮中添加1%酵母水解物和2%超级蒸汽鱼粉,各组日粮营养水平一致,采用颗粒破碎料,试验期42 d。结果表明:试验组3周龄体重有高于对照组的趋势(P=0.092),试验组4、5、6周龄体重显著高于对照组(P<0.05);试验组5周龄平均日采食量较对照组降低2.87%,差异显著(P<0.05)。0~3周龄,试验组体增重较对照组提高1.92%,差异显著(P<0.05);4~6周龄,试验组体增重较对照组提高1.97%,料肉比降低4.02%,差异显著(P<0.05);0~6周龄,试验组体增重较对照组提高1.95%,料肉比降低2.79%,差异显著(P<0.05)。与对照组相比,试验组14日龄禽流感H5-Re12株、禽流感H5-Re11株、禽流感H9抗体水平分别提高6.78%、10.00%、5.63%(P>0.05);21日龄新城疫抗体水平试验组显著高于对照组,提高41.5%(P<0.05),禽流感H5-Re12株、禽流感H5-Re11株、禽流感H7、禽流感H9的抗体水平试验组比对照组分别提高了36.9%、16.6%、17.1%、16.6%,差异不显著(P>0.05)。通过添加优质鱼粉、酵母水解物,优化蛋雏鸡日粮原料组成,能够提高0~6周龄雏鸡的体重,促进雏鸡的生长发育;对雏鸡新城疫、禽流感抗体水平的提升有积极作用。The trial was conducted to study the effects of rational structure on growth performance and antibody levels of Jinghong No.1 layer chicks.Seven hundred and twenty 0-day-old Jinghong No.1 layer chicks with the same similar body weight and good health were randomly divided into 2 groups with 3 replicates per group and 120 chicks per replicate.The trial lasted for 42 days.Chicks in control group were fed a basal diet,and chicks in trial group were fed experimental diet which was added 1%yeast hydrolysate and 2%fish meal on the basis of the basal diet.The results showed as follows:The body weight at the age of 4,5 and 6 week in experimental group were 2.7%,2.4%and 2.0%higher than those in control group(P<0.05).The body weight gain of 0~3,4~6 and 0~6 week of age in experimental group were 1.92%,1.96%,1.94%higher than those in the control group(P<0.05).The antibody level of Newcastle disease at 21 days was 41.5%higher than that of the control group and there was significant difference(P<0.05).The supplemented with 1%yeast hydrolysate and 2%fish meal on the basis of the basal diet could promote body weight of chickens developed well and had good performance on antibody leves.
