Bovine neonatal pancytopenia (BNP), a newly emerged syndrome of discussed etiology in calves, has been diagnosed since 2006. Here we describe first cases of BNP in Poland. Between September 2008 and April 2011, 62 cases of BNP were diagnosed in dairy calves. Bleeding skin lesions were mostly pronounced in summer and early autumn. Severe thrombocytopenia was observed in all sick animals. All calves came from herds vaccinated against BVDV infection with PregSure BVD vaccine (Pfizer). Substitution of colostrum from dams of BNP positive calves with colostrum from dams from herds free of BNP was the only effective measure to avoid new cases in affected herds.
牛新生仔畜全血细胞减少症（BNP）是犊牛中一种病因尚在讨论的新出现综合征，自2006年以来已得到诊断。本文描述了波兰首例BNP病例。在2008年9月至2011年4月期间，在奶牛犊中诊断出62例BNP。皮肤出血性病变在夏季和初秋最为明显。在所有患病动物中均观察到严重血小板减少症。所有犊牛均来自用PregSure BVD疫苗（辉瑞公司）接种过牛病毒性腹泻病毒（BVDV）感染疫苗的牛群。用无BNP牛群中母牛的初乳替代BNP阳性犊牛母牛的初乳是避免受影响牛群出现新病例的唯一有效措施。
