| 摘 要： | 为探索不同剂量维生素C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 共5 组,每组设4个重复,每个重复12羽.A组为对照组,对B、C、D、E 4组的鸡颈部皮下注射新城疫Ⅰ系疫苗,在4个试验组的日粮中分别添加0、250、500、750 mg/kg的维生素C,分别在处理后的第7、14、21、28天采样测定供试鸡的脾脏、胸腺、法氏囊等免疫器官指数及血清中的新城疫抗体HI效价.结果显示,添加维生素C的C、D、E 组的脾脏、胸腺、法氏囊等免疫器官指数均显著高于B 组(P＜0.05),HI效价也显著高于B组(P＜0.05),日粮中500 mg/kg的维生素C添加量效果最好(P＜0.05).表明在鸡的日粮当中适当添加维生素C能显著促进脾脏、胸腺、法氏囊等免疫器官的生长发育,增强免疫系统产生抗体的能力,能改善鸡体的免疫机能.

| Abstract: | To explore the effects of different dose of dietary vitamin C(Vc) on immune fuctions of layer,240 forty-five-day-old Roman brown eggshell layers were randomly divided into five groupes with 48 layers for each groupe which had 4 replicates(12 layers per cage).The A groupe was control and the B,C,D,E groupe were injected with series of Newcastle disease vaccine subcutaneously.The basic diet with Vc levels of 0,250,500,750 mg/kg were fed to the C,D,E groupes,and the spleen,thymus,bursa organ index,the serum HI... |
