摘要: 以中药黄芪为主组成方剂1、2、3,在含有高母源抗体的肉雏鸡群中饮用,用新城疫(ND) IV 系疫苗点眼进行常规免疫,然后分别于9、20、28、35、40、45日龄测定血液中HI 水平,组方3对7~45日龄免疫肉鸡新城疫抗体提高1.2个滴度(log2),并能提高抗体水平的均匀度,延长有效抗体效价14~18 d;提高出栏体重9.5%,提高成活率3.4%;料重比降低9.0%;组方3对雏鸡法氏囊指数和脾脏指数在9和45日龄测定值都极显著高于对照组(P<0.01),胸腺指数45日龄时,与对照组相比差异极显著(P<0.01);组方3雏鸡EAC 花环率均极显著高于对照组(P<0.01);试验组ANAE 阳性率极显著高于对照组(P<0.01);试验组在9和45日龄雏鸡红细胞C3b花环率显著提高, IC花环率降低,与对照组比较,差异极显著(P<0.01)。黄芪组方对肉雏鸡有显著的增强机体免疫作用。

Abstract: Taken the young meat chicken of high pathogenicity with prescriptions1,2 and 3, meanwhile immuning with ND IV,then determinating the level of HI on day 9,20,28,35,40,45.Prescriptions3 could pair the immune body 1.2 titers (log2) on day 7~45, make the uniformity of immune body , lengthen the effective immune body 14~18 days; enhanced leaves the pen body weight 9.5%;enhanced survival rate 3.4%; the material anharmonic ratio reduces 9.0%;the law pouch index and the spleen index in 9th the age and on 45th the age measured all extremely remarkably was higher than the control (P<0.01);the index of the chest gland on 45th was remakable(P<0.01);the rate of EAC was extremely remarkably (P<0.01);the gender rate of ANAE was dominotaly(P<0.01);the rate of C3b was remarkably enhanced and the rate of IC was lower on the 9th and 45th(P<0.01).The prescription of Radix Astragali could remarkably enhance the organism immunity function of the young meat chicken.
