| 摘 要： | 为了探讨不同剂量维生素C（vitamin C,VC）对蛋鸡免疫机能的影响，将240只体重相近的45日龄罗曼褐壳蛋鸡随机分为A、B、C、D、E 5组，每组4个重复，每个重复12只。A组不进行免疫，日粮中也不添加VC，为对照组，B、C、D、E 4组颈部皮下注射新城疫Ι系疫苗进行免疫，并在该4组日粮中分别添加0、250、500、750 mg/kg的VC，分4周测脾脏、胸腺、法氏囊等免疫器官指数及血清中新城疫HI抗体效价。结果显示，添加VC的C、D、E组，蛋鸡脾脏、胸腺等免疫器官指数均显著（P＜0.05）或极显著（P＜0.01）高于B组，法氏囊指数在第21、28天显著高于B组（P＜0.05），新城疫HI抗体效价极显著高于B组（P＜0.01），且以日粮中500 mg/kg的VC添加量效果最好。由此可见，在鸡的日粮中适当添加VC能促进脾脏、胸腺等免疫器官的生长发育，显著增强免疫系统合成分泌抗体的能力，从而提高鸡体的免疫机能。

| Abstract: | To explore the effects of different dietary vitamin C(VC) levels on immune fuctions of layer,240 forty-five-day-old Roman brown eggshell layers were randomly allocated to five groups(A,B,C,D,E) with 48 layers for each group which had 4 replicates(12 layers per cage).A group was control and B,C,D,E groups were injected with I series of Newcastle disease vaccine in subcutaneous.The basic diet with VC levels of 0,250,500,750 mg/kg were fed to B,C,D,E groups,and the spleen,thymus,bursal's organ index and serum ... |
