【摘要】 探讨非洲鸵鸟早期血清抗体免疫球蛋白 (IgG)含量的变化规律。建立双抗体夹心ELISA方法检测 7～15 0日龄鸵鸟的血清抗体IgG水平。结果表明 ,30日龄前 ,雏鸵鸟血清抗体IgG水平持续呈极显著性下降(P <0 0 1) ;30日龄后 ,显著性上升趋势一直保持到 6 0日龄 (P <0 0 5 ) ,然后上升缓慢 (P >0 0 5 ) ,75日龄达最大值 ,之后缓慢下降 (P >0 0 5 ) ,趋于稳定更多还原

【Abstract】 TO STUDY THE CHANGING LAW OF IGG OF EARLY SERUM ANTIBODY IN OSTRICH DOUBLE ANTIBODY SANDWICH ELISA WAS ESTABLISHED TO DETECT THE LEVEL OF IGG OF SERUM IN OSTRICH AGED FROM 7 TO 100 AND 50 DAYS. THE RESULTS SHOWED THAT THE LEVEL OF IGG OF SERUM ANTIBODY IN LITTLE OSTRICH DECREASED SIGNIFICANTLY(P<0 01)BEFORE THIRTY DAYS OLD AND INCREASED SIGNIFICANTLY (P<0 05)FROM THIRTY TO SIXTY DAYS OLD AND REACHED THE HIGHEST VALUE AT SEVENTY-FIVE DAY. AFTER THAT, THE LEVEL TENDED TO STABILITY DESPITE INSIGNIFICANT DECREASE.更多还原
