延安市鸡新城疫免疫抗体水平测定与分析
|
摘要
为了解延安市各县(区)鸡新城疫的免疫情况和疫苗免疫效果,于2017年春季和秋季分别对延安市甘泉、志丹、吴起、宝塔等13个县(区)的鸡新城疫疫苗免疫鸡进行了新城疫免疫抗体水平检测,并对测定结果进行分析,做出相应的评价,同时在各县(区)进行了调查。结果表明,采集的1 573份新城疫疫苗免疫鸡血清新城疫抗体总体合格率为83.73%,说明延安市13县(区)新城疫免疫抗体合格率较高;但活禽交易市场所采集鸡血清和雏鸡血清鸡新城疫免疫抗体合格率分别为68.93%和75.26%,抗体合格率相对较低,且抗体水平也较低,存在潜在的风险,应该引起足够的重视。经过二免和三免后鸡新城疫免疫抗体水平较高,说明生产中进行二免和三免的免疫操作程序是有必要的和值得推广的。
In order to understand the immune status and immune effects of the chicken Newcastle disease in each county(district)of Yanan city,the serum antibody levels of Newcastle disease virus in 13counties(district)of Ganquan,Zhidan,Wuqi and Baota of Yanan city were tested in Spring and Autumn of 2017,and the immune effects was monitored and measured.The analysis and corresponding evaluation were carried out.The results showed that the total qualified rate of immune antibodies in 1 573 chicken sera was83.73%,which indicated that the qualified rate of immune antibody of NDV in 13counties(districts)of Yanan was higher.But the qualified rates of the seral immune antibody in market chickens and chicks were68.93%and 75.26% respectively,the qualified rate of antibody was relatively low,and the level of antibody was also low,and there was potential risk.It should be paid enough attention.After two or three immunizations,the antibody level was higher,which indicated that two or three immunization procedures were necessary and worthy of promotion.
