【摘要】：近期在河南、山東、河北、安徽、山西等地,5~9周齡的雛雞和育成雞出現(xiàn)急性死亡,一般死亡率在10%~30%,嚴(yán)重時(shí)可達(dá)80%,給養(yǎng)殖戶(hù)造成巨大損失,經(jīng)流行病學(xué)調(diào)查、臨床診斷、剖檢診斷及實(shí)驗(yàn)室診斷,確診為由Ⅰ群禽腺病毒引起的心包積液-肝壞死綜合征。目前該病沒(méi)有特效的治療方法,筆者選取典型病例肝臟,加生理鹽水,經(jīng)勻漿、過(guò)濾、滅活制成滅活水苗免疫雞群,適時(shí)監(jiān)測(cè)抗體,當(dāng)抗體水平達(dá)到26時(shí),收集雞蛋,制成抗心包積液-肝壞死高免卵黃,對(duì)發(fā)病雞群進(jìn)行防治取得滿(mǎn)意效果。
