(1)制定合理的免疫程序：在制定免疫程序时要考虑到疾病对鹅的日龄敏感性，疾病的流行季节、鹅品种或品系之间差异、母源抗体的影响，其他人为的因素、社会因素、地理环境和气候条件的影响等，以制定出适合.本场的免疫程序。<br></br></h3></br><p arial="arial" background-color:="background-color:"

(4)搞好疫苗的运输与保管：小鹅瘟冻干疫苗，自生产之日起在-15度的条件下可保存2年，在10-15℃的条件下只能保存3个月。因此，在疫苗运输、保管中要确保低温，防止疫苗包装标签虽然在有效期内，但效价明显降低。甚至失效。</h3></br><p arial="arial" background-color:="background-color:" border-box="border-box"

text-align:="text-align:" ui="ui" yahei="yahei"> (5)饮水疫苗应加倍，饮用疫苗前应停水4小时左右，.严禁用含氧离子的自来水、疫苗稀释后要在1小时内用完。避免阳光直接照射疫苗，否则影响免疫效果。</h3></br><p arial="arial" background-color:="background-color:"

sans-serif="sans-serif" sc="sc" text-align:="text-align:" ui="ui" yahei="yahei"> （6）避免消毒药对疫苗的影响 在养鹅生产中每周都用消毒药对鹅舍、用具进行消毒和洗刷，还有的养鹅户用 0.05%高锰酸钾溶液饮水，用于肠道防腐消毒，小鹅瘟冻干疫苗是一种活毒疫苗，与消毒药接触就会失去活力。使疫苗失效，引起免疫失败。因此，在接种小鹅瘟冻于疫苗前、后 5天内严禁饮用消毒药溶液，经消毒后的饮水器和食槽要用洁净清水冲洗干净。</h3></br><p arial="arial" background-color:="background-color:"

(8)降低母源抗体的中和：母源抗体是指种鹅较高的小鹅瘟等免疫抗体经卵黄传输给下一代雏鹅，这种天然被动免疫抗体，可抵抗小鹅瘟等相对应强毒的侵袭，如雏鹅过早接种疫苗，免疫期越短。因此，应根据雏鹅的母源抗体度，决定雏鹅的首次免疫接种日龄。</h3></br><p arial="arial" background-color:="background-color:"
