按日龄采集某场5窝免疫母猪所产仔猪血样259份,运用农业部规定的猪瘟正向间接血凝试验法检测猪瘟抗体效价,并以抗体效价对数对日龄作图。运用了残数法对猪瘟母源抗体代谢动力学进行了研究,建立数学模型,求算出该场哺乳仔猪猪瘟母源抗体代谢动力学参数 ka、k、t1/2(a)和 t 分别是2.2144/d、0.03887/d、7.5 h、和17.83 d。依据猪瘟母源抗体代谢动力学参数 t 为17.83 d,确定该场哺乳仔猪在28~30日龄进行首免,可获得满意的合格免疫率。
按日齡採集某場5窩免疫母豬所產仔豬血樣259份,運用農業部規定的豬瘟正嚮間接血凝試驗法檢測豬瘟抗體效價,併以抗體效價對數對日齡作圖。運用瞭殘數法對豬瘟母源抗體代謝動力學進行瞭研究,建立數學模型,求算齣該場哺乳仔豬豬瘟母源抗體代謝動力學參數 ka、k、t1/2(a)和 t 分彆是2.2144/d、0.03887/d、7.5 h、和17.83 d。依據豬瘟母源抗體代謝動力學參數 t 為17.83 d,確定該場哺乳仔豬在28~30日齡進行首免,可穫得滿意的閤格免疫率。

259 blood samples were collected according to piglet ages from 5 broods of classical swine fever immunized sows and were tested for classical swine fever antibody titers by using the MOA-approved indirect hemagglutination assay.And the classical swine fever antibody titer logarithm was plotted in relation with the ages.The maternal CSF antibody metabolic dynamics was studied by means of the residual method and a mathematical model was established.The results showed that the maternal CSF antibody metabolic kinetic parameters ka,k,t1/2(a)and t were calcutated respectively as 2.2144/d,0.03887/d,7.5 h and 17.83 d.According to the maternal CSF antibody matabolic dynamic parameter t=17.83 days,the first vaccination day for suckling piglets in the farm was determined at 28~30 day-old,with satifactory immune efficiency.
