摘要
为了解安溪县鸡白痢流行情况,于2021-2023年对安溪县4家规模蛋鸡场、随机抽取24个乡镇的34家中小规模场、61家散户进行鸡白痢血清学调查。通过调查发现,不同养殖年份、养殖条件下鸡群鸡白痢的感染程度不同,散户的鸡白痢感染率(30.33%)高于规模蛋鸡场(7.26%)和中小规模养鸡场(15.80%),母鸡鸡白痢感染率(18.91%)略高于公鸡的感染率(17.92%)。总体分析可知,安溪县鸡群中鸡白痢感染情况普遍存在,感染水平与多个因素有关。亟需开展鸡白痢病种的净化工作,通过检测淘汰阳性鸡,并加强生物安全措施,达到区域净化该病种的效果。
In order to understand the prevalence of pullorum in Anxi county,a serological survey of pullorum was carried out in 4 large-scale hens breeding farms,34 small and medium-sized breeding farms and 61 free range households randomly selected from 24 townships in Anxi county from 2021 to 2023.The results showed that the infection degree of pullorum varied in different breeding years.Among them,the infection rate of pullorum in households was 30.33%,which was higher than that in the large-scale layer farms(7.26%)and the small and medium scale chicken farms(15.80%),The probability of chicken pullorum infection in hens(18.91%)was also slightly higher than that in cock(17.92%).Overall analysis showed that pullorum infection was common in Anxi chicken flocks,and the infection level was related to many factors.It is urgent to carry out the purification of pullorum,eliminate the positive chickens by testing,and strengthen the bio-security measures,to achieve the effect of regional purification of the disease species.
