| 摘 要： | 试验用ＡｒｂｏｒＡｃｒｅ肉仔鸡６７２只，随机分成７个处理，每处理９６只，雌雄各半。２×３因子设计，其中维生素Ｅ２个水平分别为２０、８０ｍｇ／ｋｇ；抗坏血酸３个水平依次为２００、４００和８００ｍｇ／ｋｇ。另外设一个不添加维生素Ｅ和抗坏血酸的对照组。试验期分为０～２周龄和３～４周龄两个阶段。试验结果表明，提高日粮维生素Ｅ水平（８０ｍｇ／ｋｇ）对肉仔鸡体内抗坏血酸的合成有促进作用，抗坏血酸对维生素Ｅ的作用不明显。随着日龄的增加，肉仔鸡血清维生素Ｅ的含量呈下降趋势，日粮尽早添加维生素Ｅ可以减缓血清维生素Ｅ的下降；肉仔鸡体内可以合成一定量的抗坏血酸，合成能力随日龄的增加而增强。日粮高水平的维生素Ｅ（８０ｍｇ／ｋｇ）可提高２８日龄肉仔鸡血液淋巴细胞转化率和血清新城疫抗体滴度，抗坏血酸对肉仔鸡细胞及体液免疫功能影响不显著。

| Abstract: | newly hatched chicks of Arbor Acre which consisted of half male and half femals were fed from 1 to 28 day of age on diets containing different concentrations of vitamin E(40, 80mg/kg)and ascorbic acid(200, 400, 800mg/kg).The control group contained no vitamin E and ascorbic acid.Results from the study indicated that ascorbic acid synthesis in chicks is increased in high dietary vitamin E(80mg/kg)status. However,a sparing effect of ascorbic acid on vitamin E was not observed although exogenous supply was furnished. The serum vitamin E of the chicks declined rapidly with the increase of the age.Meanwhile, the chicks could synthesize some ascorbic acid in body and this capacity was increased with the increase of the age, High dietary vitamin E(80mg/kg) could improve the antibody titers of hemoagglutination inhibition of chicks immunized by New Castle disease vaccine and blood lymphocyte transformation function of the chicks stimulated by phytohemagglutinin(PHA),but same effect was not documented with ascorbic acid. |
